Foreword by the Act. Rector Universitas Negeri Jakarta

On behalf of the act. Rector, I am

honoured and delighted to welcome you to

the Science and Mathematics International

Conference (SMIC) which is organized by

the Faculty of Mathematics and Natural

Science, Universitas Negeri Jakarta,

Indonesia. Welcome to all speakers,

presenters and participants of the

conference and wish you all have great

success in the conference.

Distinguished guest, ladies and gentlemen, the globalisation

processes which related to the revolution industry 4.0 have linked

education to technological and economic development. The advanced

technology and development economy contribute to the complexities

of social life and underpinning the importance of preparing the young

generations. Educators and education systems are charged with the

task of preparing students to live in a complex global society that will

require them to deal with local, national and global issues. Therefore, it

is essential for the education system and educators for preparing

generation in facing these challenges.

Science and mathematics play important roles in the development of a nation that eventually we can stand high and

compete at the global level. However, the challenges are how to build

the mindset of the next generation taking part in this development.

SMIC aims to bring together academics, scientist, students,

postgraduate students and practitioners to share and discuss theoretical

and practical knowledge of problems, new trends and applications in

science and mathematics.

Distinguished guest, ladies, and gentlemen, the success of the

conference depend ultimately on the many people who have worked

hard in planning and organising both the technical program and

supporting social arrangements. Please let me extend my deepest

gratitude and highest appreciation to all committee members. I would

also like to thank all keynote speakers, invited speakers as well as

workshop speakers for the contributions. I would like to thank all

sponsors and individuals who have contributed to the organisation and

success of this conference, each of the participants for attending our

STEAM and revolution industry 4.0:

Empowering higher education for preparing

future generations

Intan Ahmad*

Universitas Negeri Jakarta and Institut Teknologi Bandung

Ministry of Research, Technology, and Higher Education Indonesia

Email: [email protected]

Abstract

The current challenges of globalisation as the era of industrial

revolution 4.0 (the era of technology disruption) in term of rapidly

changing, highly competitive, and the increasingly complex world

require higher education for preparing their graduates. As globalisation

increases through international trade, transportation, and the ubiquitous

transfer and sharing of information, it will require higher education

graduates who are skillful and able to adapt to and face fast

connectivity and transformation. Higher education plays an important

role in preparing the nation's young generations to be globally

competitive. Global challenges have led to the transformation of

higher education organisations, policies, and strategies. This

transformation focuses on developing students' competencies and

empowerment as individuals, as the citizen, and as agents of change

who are responsible, creative, innovative and able to contribute to

society, the nation, and to world civilisation. In specific, STEAM

becomes the current topic in science and mathematics and play

important roles in the industrial revolution 4.0, not only the skillful

graduates in these fields but also the holistic individuals who can

develop empathy and ethics. The graduates not only require

understanding the theoretical and practical knowledge of problems in

STEM, but also develop 4C (Critical Thinking, Creative Thinking,

Communication, and Collaboration). It is important for higher

education for shaping economic development by creating graduates

who can provide job opportunities as entrepreneurs with literacy,

leadership skills, social and multicultural skills, and other life skills.

Therefore, reformation of the higher education system, especially in



14

creating holistic individuals for facing the challenges and being the

agent of changes in the nations.

Keywords: higher education, generations, revolution industry 4.0,

Mathematics teachers working and learning

collaboratively in communities of practice

Berinderjeet Kaur*

National Institute of Education

Singapore

Email:[email protected]

Abstract

Mathematics teacher learning beyond pre-service education takes many

forms, even though they may have the same intent of improving classroom

instruction. The forms of continuing professional development (PD) teachers

engage in are often related to systemic support, the acceptance of PD by

teachers as a career-long endeavour or an administrative duty and teacher

compliance due to top-down directives or teacher agency. In addition, there

are several models of continuing PD and they may be categorized as

transmission (training, award-bearing, deficit and cascade), transitional

(standards-based, coaching/mentoring, community of practice) and

transformative (action research). This categorization suggests increasing

capacity for teacher autonomy as one moves from transmission through

transitional to transformative categories. In this lecture we describe how

communities of practice emerged in two PD projects involving mathematics

teachers in Singapore. Both projects were based on a hybrid model of PD that

integrates the “training model of PD” with sustained support for teachers to

integrate knowledge gained from the PD into their classroom practice.

Keywords: continuing professional development, mathematics teachers,

communities of practice, hybrid model

* Berinderjeet Kour is Professor in Mathematics, National Institute of

Education (NIE), Singapore. She played the critical role of training

Mathematics teachers for Singapore schools and many students in the

schools have benefited from her work which motivates them to learn

Mathematics in the most engaging ways. She has been engage in numerous

international studies of Mathematics Education and was Mathematics

consultant to TIMSS 2011. She is also a member of the MEG (Mathematics

expert group) for PISA 2015.

Keynote Speaker 3

New directions of STEM education

Russell Tytler*

Deakin University

Australia


Abstract

There is increasing global concern about the engagement of students with the

STEM subjects, and the need for students to acquire the STEM skills

necessary for participation in 21st century living and work futures. Calls for

new directions in STEM Education amount to a re-thinking of the STEM

subject disciplines. Drawing on an analysis of the discourse around STEM

advocacy, this paper investigates the nature of drivers of a strong STEM

interdisciplinary agenda, and the implications for school systems and for the

STEM disciplinary subjects. An analysis of integrated STEM innovations in

Australian schools raises questions about the relationship between authentic

interdisciplinary STEM tasks and the nature of STEM subject epistemes. It is

argued that the STEM subject disciplines in schools need to remain the basis

of STEM learning but need to be significantly re-thought if they are to

answer the call for critical and creative thinking that underpins STEM

advocacy.

Keywords: STEM, interdisciplinary, critical and creative thinking

The nature of mathematics and its challenges

Carlene Arceo*

University of the Philippines

Philippines


Abstract

Much of the time, mathematics is taught with focus on computational skill.

Whilecomputational skill is critical, it is not the only concern of mathematics.

A major concern ofmathematics is making sense of real world phenomena, of

helping to create an understandingof how things work and what can happen

next. Thus, instead of leaving students with theimpression that math is only

for classroom consumption, it should be taught as something useful,

powerful, and beautiful. Consider the natural partnership between science

and math. Math is called the “language of the sciences”. It can also be the

language of other disciplines and do for these disciplines what it does for the

sciences. Math performs different roles for its different users, depending on

their area and purpose, but its unifying thread and reason is its logic,

organization and elegance. This keynote will depict mathematics as a bridge

which provides services as varied as the userswho use it. Meanwhile, it is a

bridge that may be just as appreciated for its sheer beauty.

Keywords: mathematics, computational skills, language of science, real

world

Keynote Speaker 5 Large-area (001) faceted anatase TiO2 for

high-photoactivity in dye-sensitized solar cells

Akrajas Ali Umar* and Siti Khatijah Md Saad,

Universiti Kebangsaan Malaysia

Malaysia


Abstract

Charge-transfer or reaction at an interface of a photoactive materials, such as

anatase TiO2, is critically influenced by the nature of available exposed

crystalline plane of the surface. A highly-energetic crystalline plane,

particularly (001) in anatase TiO2, promises an active physico-chemial

reaction, generating various process including facile and rapid charge

transfer, efficient exciton transport and separation, for enhanced

photocatalysis or photon to current conversion performance. In this talk, we

will present a discussion on various aspect of (001) faceted anatase TiO2 that

includes the review of its unique electronic properties and surface physico-

chemical properties and their synthetic strategy. In order to giving a clear

idea on the role of facet in anatase TiO2 on their photoactivities, their

performance in dye-sensitized solar cell application will be discussed. The

nature of interfacial charge-transfer on this surface will also be review in this

talk.

Keywords: anatase TiO2, (001) facets, charge-transfer, photoactivity, solar

cells

ST2EAM education in the anthropocene:

Transforming the dark side of human nature

Peter Charles Taylor*

Murdoch University

Australia


Abstract

Humanity has created a new geological era – the Anthropocene -

characterized by the massive impact of our collective footprint on the

planet’s natural and social systems. Witness escalating global crises due to

anthropogenic global warming – genocidal sea level rise, catastrophic

wildfires, super destructive hurricanes, death of coral reefs, record droughts

threating national food security – and pollution of the world’s oceanic

ecosystems and food chains by microplastic waste.

Despite decades of international commitments, most recently the

UNFCCC’s 2015 Paris Agreement on Climate Action, progress has been

disappointingly slow, with economically powerful nations such as the USA

threatening to withdraw cooperation. For the past 10 years, ongoing attempts

by Australian Governments to establish carbon emissions reduction policy

for industry have been derailed by climate change sceptics. The sceptics have

created in the public mind a false but compelling dichotomy between national

economic security and trust in climate science.

Clearly, science education is failing to create a well-informed and

ethically astute citizenry capable of not only understanding modern Western

science - its strengths and limitations - but, most importantly, engaging in

critical reflection on vested interests framing (and hijacking) public debates

about how to achieve a balance between economic, social and environmental

sustainable development

The current push to create curriculum synergies between Science,

Technology, Engineering and Mathematics (i.e., STEM) promises to prepare

students for employment in the fourth industrial revolution; a largely

economic imperative. However, an uncritical perspective on the historic role

of STEM in society is likely to encourage students to (continue to) turn a

blind eye to the ways in which STEM provides us with the means for

destroying spaceship Earth.

In this presentation, I will argue that to save the future of our

planetary ecosystems (and our own species) from the dark side of human

nature we need a transformative curriculum perspective that enriches STEM



20

education. This transformative curriculum perspective can be represented by

the equation: STEM + T + A = ST2EAM. By integrating the Arts (A) with

STEM we can create an interdisciplinary curriculum design space for

enacting transformative (T) pedagogies that not only enable students to

develop disciplinary knowledge/skills, but also (i) awaken their creative self-

consciousness, (ii) elevate their moral/ethical and spiritual awareness, and

(iii) empower them to practice social and environmental justice.

Keywords: ST2EAM, interdisciplinary, transformative, self-consciousness,

social and environmental justice

Transformative Education at Murdoch University and Coordinator of the

has chapters throughout Asia, Africa, Middle East and Philippines. Peter’s

vision for education integrates the Arts and Sciences to foster creativity,

critical self-reflection, ethical astuteness, political awareness and

intercultural connectedness, which are essential transdisciplinary

capabilities for living and working sustainably in the complex, diverse and

contested worlds of the 21st century.

Keynote Speaker 7 Beeswax: A multi-query optimization tool for

big data

Mohamed Helmy Khafagy*

Fayoum University

Egypt


Abstract

Recently, both of academia and industries become interested in the high

potential of Big Data researches and applications. These extensive researches

led to the emergence of Apache-hosted Big Data analytics systems for both

stream and batch Big Data analytics such as MapReduce, Spark, and Flink.

However, the Big Data analytics systems need more deep researches to

optimize huge data processing with high productivity. Beeswax is an

optimized tool for Big Data analysis that built on top of Hive as the most

popular and mature Big Data querying language. The Beeswax tool can

improve the storing and processing Big Data in different optimization levels;

query translation, Join optimization, resources consumption, sharing

opportunity for multi-query optimization, multi-user in the multi-session

environment.

Keywords: big data, query optimization, map reduce

Stratosphere project and big data analytics as a whole, especially the optimization

and benchmarking of big data analytics systems. This work fits very well into the

scope of the Stratosphere project at TU Berlin, which has the goal to build a web-

scale information management system on an infrastructure as a service platform. this

project is conducted with DIMA research groups at TU Berlin, Humboldt Universität

Structure of matter – diagnosis of

misconceptions and challenge

Hans-Dieter Barke*

University of Muenster

Germany


Abstract

In teaching science we differentiate two kinds of misconceptions:

Preconcepts which young boys and girls are bringing from home or every-

day life – their special mental models about burning processes, about gases

and their properties, about substances and their changes (Barke, Hazari,

Sileshi, 2009). On the other hand we found “school-made” misconceptions

(Barke, Hazari, Sileshi, 2009) which are caused by inappropriate teaching

methods or by complexity: equilibrium, acids and bases, redox, energy

(Barke, Hazari, Sileshi, 2009).

Salts and salt solutions are not easy to teach because students know the

idea of atoms and molecules, but mostly do not follow the idea of ions. Like

in Organic chemistry they are thinking of molecules: “NaCl molecules” in

sodium chloride, even of “Cl-Ca-Cl molecules” in solid calcium chloride or

in aqueous solutions. Same with acids and bases: Students often are thinking

of “HCl-molecules” in hydrochloric acid or “NaOH-molecules” in sodium

hydroxide solution. Because they know only formulae like HCl and NaOH,

they don’t consider hydronium ions and hydroxide ions which react to form

water molecules. If a Periodic Table (www.chemischdenken.de) is introduced

with atoms and ions as basic particles of matter, students may better accept

the ions. When additionally beaker models are showing the involved ions of

salt solutions, of acids and base solutions, the world-wide stated

misconceptions should be challenged (Barke, Harsch, Schmid, 2012).

Misconceptions can be diagnosed by Concepts Cartoons (Barke, Harsch,

Schmid, 2012), they show four or five pictures of students, one with the

scientific answer, others with well-known misconceptions. Showing those

cartoons students should discuss them and come up with the scientific

answer.

The presentation will also reflect new empirical research concerning

explanations on the Submicro level. We presented Indonesian and German

students at universities usual chemical equations according to acid-base and



23

redox reactions and asked: “Which atoms, molecules or ions are involved in

the reaction, which particles are giving or accepting protons or electrons”?

If the reaction “Na2CO3 + 2 HCl H2CO3(aq) + 2 NaCl” is asked, we liked

to see the particles which react: “CO32-

+ 2 H3O+(aq)”, hydronium ions as

acids are giving each a proton (H+) to the base carbonate ion, H2CO3

molecules are formed which decompose to CO2 and H2O molecules. Sodium

and chloride ions don’t react and remain in solution, they are called

“spectator ions”. Some answers were good, but many other answers are

showing misconceptions [Wisudawati, 2018; Awilag, 2018]: students are not

used to argue on the Submicro level. Also the Laboratory jargon

(“hydrochloric acid gives one proton”) can develop misconceptions [Barke &

Buechter, 2018] – the presentation will show examples.

Keywords: chemistry misconceptions, submicroscopic level, structure of

matter, laboratory jargon

REMAD COCOPER learning strategy for

improving global competitiveness of biology

education students of State University of Malang

Herawati Susilo*

E-mail: [email protected]

Abstract

Facing the 4.0 industrial revolution, Malang State University chose life-based

learning (LBL) as the paradigm of education and its learning. As an effort to

translate LBL into the practice since 2016 a REMAD COCOPER Learning

Strategy has been developed. This strategy includes Reading activities,

creating mind or concept Maps, Discussing, Collaborative Learning,

Cooperative Learning, Presenting, Elaborating, and Reflecting. Through this

learning strategy Biology prospective educators are given the opportunity to

develop their capabilities through a professional learning community that

allows them to design learning that best suits the needs of the times and pay

attention to the development of 21st century life skills for their students. This

learning strategy has been piloted in several courses at the undergraduate and

graduate levels. The test results show that this strategy can be used to teach

students LBL and develop their capabilities because every activity has the

potential to develop basic literacy, 4Cs competencies, and their character.

Based on the results of the trial it was concluded that this strategy can be

utilized to improve global competitiveness of prospective biology educators.

The recommendation is that efforts can be made to improve the learning

processes by emphasizing authentic assessment more rigorously and

consistently.

Keywords: REMAD COCOPER, learning strategy, global competitiveness,

capability development, biology education students.

Invited Speaker 2 Some contributions of mathematics in the

management of biological resources: Maximum

sustainable yield for commercial species with the

influences of spatial heterogeneity, intra specific

competition and alee effect

Asep K. Supriatna

Universitas Padjadjaran

Indonesia


Abstract

Conservation and exploitation issues often occur simultaneously, especially

when it comes to living things that have high economic value. Several

theories concerning the use of natural resources have been successfully

developed with reference to sustainable use, for example the concept of

maximum sustainable yield (MSY) and maximum economic yield (MEY).

The MSY and the MEY values are strongly influenced by various processes,

e.g. by both internal and external aspects of the related biologal processses of

the species, such as interactions between and intra species. In this talk I will

discuss about the contribution of mathematics in developing the MSY and

MEY resulting from a bio-economic model by looking at the effect of

aforementioned processes above, including spatial heterogeneity of the

species, internal competition in the species (intra-specific competition) and

the existence of Allee effects in the species. In many literature it is known a

critical threshold value for some species where if the population of the

species is below the threshold - known as the population viability threshold

(PVT) - the species will be at risk of extinction. This is known as the Allee

effect. In this talk I will discuss the influence of the threshold in determining

the level of the MSY and the MEY, through several approaches. A method

on how to parameterize the model will be also explored. Then considering in

reality almost all parameters that exist in life in nature always have

uncertainty properties, then the model with the crisp parameter is extended

into the model with fuzzy parameters. Both results are compared to see the

effect of uncertainty in determining MSY and ME.

Keywords: bioeconomic model, exploitation, conservation, spatial

heterogeneity, intra-specific competition, Allee effect, MSY, MEY,

uncertainty, fuzzy numbers

Abstract

Femtosecond laser is an advanced type of laser source that can reveal

behavior of electron dynamics of materials. This kind of laser can be used for

material synthesis and material optical characterization. In this talk, we

would like to briefly describe application of femtosecond laser to synthesis

nanoparticles and to characterize materials for batteries and fuel cells. In the

first talk, we would like to present synthesis of metal nanoparticles can be

used for catalyst material for fuel cells. Metal nanoparticles, such as gold

nanoparticles, silver nanoparticles and platinum nanoparticles were easily

synthesized using both laser ablation and photoreduction methods, in which

both methods utilized femtosecond laser. Physical properties of synthesized

nanoparticles will be exposed in this talk. In the last tallk, we would like to

describe the used of short pulsed laser to detect lithium content in material

used for lithium batteries. Identification of lithium element is important and

difficult to do using x-ray difractrometer or EDAS. Since lithium is a light

element, thus very expensive tools, such as neutron scattering, is possible to

detect lithium presence in materials. However, using simple laser-induced

plasma spectroscopy, we can detect lithium content in material easily. We

hope that this talk will open further research and application of femtosecond

laser for material synthesizing and characterizing.

Abstract

The explosion in the quantity and diversity of high frequency digital data

such as mobile phone data, mobile and online financial transactions, or social

media traffic, provides more data resources and a different way of data

collection. The Big Data’s potential keeps growing makes companies,

governments and other users must incorporate sophisticated data analytics for

faster decisions. Dealing with this big data requires a different approach and

poses challenges for so called data scientist in retrieving, managing,

visualizing, analyzing, interpreting and presenting the data. Here the

conventional statistical approaches can no longer be used. This talk would

discuss the expected profile of data science, followed by various advanced

statistical techniques from simple to the latest implemented in several big

data cases such as in health, finance, business, and public policy. In addition,

the issue how the education institution especially IT and Statistics department

should adopt this demand would be discussed. Finally, Big Data development

and research direction would be discussed as well.

Workshop Fasilitator 1

Value and Teaching Character: Ethical dilemma story pedagogy – a

strategy for teaching values in the context of science classrooms

Elisabeth Taylor* and Peter C. Taylor

Edith Cowan University

Murdoch University

Australia


Abstract

Science is perceived by many as an objective, content driven, values-neutral

discipline, while traditional science education is viewed as having a strong

emphasis on “technical rationality” and an unquestioning acceptance of the

knowledge to be learned. Many science teachers are heavily invested in this

epistemological view of science which necessitates a distinction of values

from facts. However, with the rapid advance of science and technology in an

increasingly globalised world context, new ethical questions are being raised.

Australian schools have been charged with explicitly teaching values across

all learning areas. This workshop focuses on the use of ethical dilemma

stories as a strategy for teaching values that can be used in any subject and at

any grade level. The stories present a realistic situation in which the actors in

the story encounter an ethical dilemma. In our research, participating teachers

narrated the dilemma story to the students. The story was paused at

appropriate times at which a dilemma question was asked, and students were

given opportunities for personal reflection followed by discussions with

peers. The use of ethical dilemma stories helps develop critical thinking skills

necessary to help students make ethical and moral decisions in life beyond

school.

Keywords: value and teaching character, dilemma story pedagogy, critical

thinking skills, ethics

Abstract

Seymour Papert (Papert & Harel, 1991) determined that ‘play involved

experimenting, taking risks, testing the boundaries, and iteratively adapting

when things go wrong. He sometimes referred to this process as ‘hard fun.’

Can we then create Makerspaces, places where students can go to play and

have ‘hard fun’ and still meet learning outcomes in both content knowledge

and skills? This workshop considers creating educative Makerspaces and

how to measure students’ knowledge and skills in STEM.

Learning Environment Measurement for

Teaching and Learning Improvement

Rekha Koul*

Curtin University

Email [email protected]

Abstract

Students spend up to 20,000 hours in classrooms by the time they graduate

from university, leaving a significant impact on student’s experiences and

perceptions of the learning environments they encounter. Research and

evaluation in science education focus heavily on conceptual change, which

cannot give a complete picture of the educational process. One such area

which needs more focus is the student’s understanding of and interaction

with place when engaging in place-based learning. Place-based pedagogies

were developed in a reaction to concerns that, due to globalisation, students

were becoming disconnected from the local communities, cultures and the

ecological environments surrounding them in the places that they lived. The

goal of place-based learning is to actively engage students in interacting with

their local communities through hands-on, real-world problem-solving which

leads to greater appreciation of the natural environment within which they

live and a greater connectedness to local community.In this workshop we will

briefly review the research into conceptualising, assessing and investigating

the determinants and effects of the learning environments of science

classrooms. Following which participants will be familiarised with the

structure and practical applicability of the place-based learning environment

instruments.

Two bromonaphthyl chalcones and four bromonaphthyl pyrazolines

have been docked to evaluate their potencies as anti-inflammatory. The

molecular docking study showed that compounds 2a and 3a have good

potencies as an anti-inflammatory agent, furthermore, it can be

synthesized and developed as a new anti-inflammatory agent.

Compound 2a and 3a have been synthesized under microwave

irradiation via two steps reaction. The structures of both compounds

were confirmed based on the interpretation of spectroscopic data

include UV-Vis, FT-IR, HRMS, 1H and 13C NMR. The in vivo

evaluation showed that compounds 2a and 3a with various dosages of

25, 50 and 100 mg/kg body weight have abilities to reduce

inflammation of the carrageenan-induced paw edema in male mice

(Mus musculus L.), significantly (p < 0.05) compared than negative

Carbon nanodots (CDs) from some natural materials have been

synthesized with green synthesis method assisted by microwaves.

Natural materials used are mustard stems, mustard leaves, bintaro skin,

bintaro meat, pumpkin skin and pumpkin meat. To determine the

optical properties of visible-light absorption and energy band gap, CDs

samples were analyzed using a UV-vis spectrometer. CDs from

mustard stem and leave show light absorption at a wavelength of 200-

800 nm with the highest absorption intensity at a wavelength of 300

nm with intensity of 6.08%. CDs from bintaro skin and bintaro meat

show light absorption at wavelengths of 200-600 nm with the highest

absorption intensity for CDs from bintaro skin at a wavelength of 274

nm with an intensity of 4.46%, while CDs from bintaro meat have the

highest absorption intensity at wavelength 220 nm with an intensity of

27.38%. CDs from pumpkin skin and pumpkin meat show light

absorption at a wavelength of 200-600 nm with the highest absorption

intensity at wavelengths 208 and 291 nm. The results show that natural

materials can be synthesized into CDs and have the potential to be

used as dye in the synthesis of quantum dot dye sensitized solar cell

(QDSSC).

.


In this study, we design reactor operating with five aluminum

electrodes in bipolar for harvest chlorella sp. The reactor has good

electrical stability, good stability of the good voltage circulation and

does not form accumulation of flocs on the electrodes Considering

the relative easy handling of the reactor. The experiment was done by

batch method used 1 Liter microalgae for each treatment on direct

current variated from 9, 12 and 15 volt, variated of pH from 9 to 11,

and operation time from 10 to 40 minutes. The result of treatment were

remarkably good and the efficiencies to total suspended solids (TSS)

as the amount of microalgae removed reached to 51,55% using a

current density of 8.3 mA cm-2 potential 15 volt, pH 11 for 30 min

The energy consumption at these optimal conditions was very low

(0.163 kWhm−3). The analysis proximate of chlorella biomass showed ash content 32,45%, fat content 1,62%, water content 15,32,

carbohydrate content 32.15% and protein 34,86, 0.89% lipid content

0,89%, carotenoid content 37% and total choropil 1.4%

Impact Of Power Harmonic On Presice And Discriminative

Tripping Of The Relay System For Earthing Protection In

Un-Grounded 6kv Grids Of Quangninh Underground mines

Ho Viet Bun1, Le Xuan Thanh

1,2Hanoi University of Mining and Geology, Hanoi, Vietnam

.


The ratio of earthing in underground mines’ electrical system of is

from 75% to 86% of the total faults. When an earth fault happens,

there are always odd level power harmonics (3, 5, 7, 9, 11, 13). These

harmonics can have bad influence on the relay system. Consequently,

the protection system could operate abnormally or have wrong

tripping. Article bases on the real data measurements (as shown in

figure 1, 2) and the simulation in Matlab to analyze the kinds of

harmonics to filt/eleminate for improving the sensitivity as well as the

discriminative tripping of the relay system. The analysis is also the

recommendations for operators of 6kV grid to have a better relay

protection system’s performance. The ratio of earthing in underground

mines’ electrical system of is from 75% to 86% of the total faults.

When an earth fault happens, there are always odd level power

harmonics (3, 5, 7, 9, 11, 13). These harmonics can have bad influence

on the relay system. Consequently, the protection system could operate

abnormally or have wrong tripping. Article bases on the real data

measurements (as shown in figure 1, 2) and the simulation in Matlab to

analyze the kinds of harmonics to filt/eleminate for improving the

sensitivity as well as the discriminative tripping of the relay system.

The analysis is also the recommendations for operators of 6kV grid to

have a better relay protection system’s performance.

In the designing procedure of MV grid, ecotechnic assessment must

cover a not only technical matters but also economic effect. MV grids

are set of facilities, including conductor, insulator strings, and

connection devices. Actual operation indicates that the losses of grid

are approximately over 50% of total network losses. Because of the

importance of these losses, it must be taken into account in designing

as well as operating procedure of network. Certainly, it is a strong key

factor influence significantly on ecotechnic assessment. However, the

application of the losses in ecotechnic assessment always gets

difference because of lines’ physical properties. The paper focuses on

analyzing this kind of difference called skin effect. An algorithm based

on Matlab calculation is utilized to compare with real data

measurement to deduct an elastic factor corresponding to each line’s

cross section. The approach set of factors help the power utilities to

have better ecotechnic assessment in the beginning stage of grid

designing.

Neem has been well known as a medicine herbal because of its

benefits, such as antihyperglycemic, antifungi, reducing cholesterol,

spermicide, especially in herbal contraception. The mice were orally

administered the aqueous seed extract of neem (0.25, 0.50 and 1.0

mg/kg body weight) for 36 days and then stopped the treatment for 36

days. This experiment observed on reversibility anti fertility and

morphometry of the reproductive organ of male mice (Mus musculus).

Reproductive organs were observed were litter size, size of testis and

epididymis. Research used a completely randomized design, and the

data were analyzed by Tukey’s multiple comparison tests. The results

showed that reduction fertility, but both normal on testis and

epididymides size. Aqueous seed extract of neem with doses 0.25 and

0.50 mg/kg body weight (BW) did not cause appreciable alterations in

morphometry appearance of the epididymis (P>0.05), while doses of

0.25 and 0.50 mg/kg affected testis weight. Size of male mice

reproductive organs that were testis length, testis width, and

epididymis length gave significantly different results (P<0.5).

However, fertility and reversibility of reproductive organ were affected

by this treatment and gave significantly different (P<0.05). After 36

days of withdrawal of the treatment, the alterations in the reproductive

organs of male mice were recovered to control levels. So, aqueous seed

extracts of neem caused anti fertility and reversibility alterations in the

male reproductive organs of DDY mice.

Optimal Retention for Stop-Loss Reinsurance with

Distribution-Free Approximation

Reinsurance is a service of reinsurance of decisions made by insurance

companies, guarantee companies or other reinsurance companies.

There are several types of reinsurance, one of them is stop-loss

reinsurance. In stop-loss reinsurance, reinsurance company will

determine the bound of its ability to guarantee the risk and the

remainder of the risk that cannot be guaranteed will be transferred to

the reinsurance company. The bound of this ability is called retention.

Therefore, optimal retention is needed for the insurance company to

prevent bigger loss. One of the ways that can be used is an

optimization of VaR (Value-at-Risk) risk measure. However, this

optimization cannot be done if incomplete information is known to

estimate the distribution of total loss that accepted by the insurance

company, for the example, there are only two first moments and

support in the interval [0, b] where b can have value +∞. Therefore, an

approximation that utilizes this incomplete information can be used,

this called distribution-free approximation. With this approximation,

can be seen the result that the obtained optimal retention is depended

on 2 first moments and safety loading obligation that determined by

the reinsurance company.

It is well recognized that the value at risk (VaR) gives a benchmark

risk measure in the area of modern risk management. Here we estimate

VaR for the portfolio problem which consists of two risks random

factors. We consider the situation that these two random variables are

not necessarily independent but possess certain nonlinear relation

represented by a copula. As it is well known, a copula function

provides an analytical tool to investigate a possibly nonlinear

connection between random variables. Because of its flexibility, the

method of copulas has now become a standard issue in the risk management. We deal with the estimation of VaR for the portfolio

problem with related to a copula. Some examples are computed.

Commuting can’t be separated from worker’s routine. This mobility

can reduce the population density on city. The difference between high

wages in the city and the low cost of living in the suburbs can also

provide benefits for commuter workers. However, these benefits must

be paid by reducing the health conditions of commuter workers. The

health conditions of poor commuter workers will cause harm to the

company and himself. This study aims to determine the factors that

affect health complaints on commuter workers who come from the

area of Bodetabek. The data used in this research is sourced from the

Jabodetabek Komuter Survey 2014. The samples in this survey were

selected by Two-Stage Sampling so that the data collected will have a

hierarchical structure. Hierarchically structured data is more

appropriate when analyzed by multilevel logistic regression. However,

the limited number of units at the level two causes the parameter

estimation in multilevel logistic regression will be bias. By applying

Bayesian multilevel logistic regression analysis, the results showed

that commuting distance, commuting time, commuting mode, stress,

traffic congestion, education, and employment status significantly

affects health complaints of commuter workers. Thus, government is

expected to improve the quality of public transportation services in

terms of convenience, timeliness, ease of access, and low cost.

Clustering is a common technique for statistical data analysis used in

machine learning and data mining. Most of the existing clustering

algorithms are designed to focus on one data type only, either numeric

or categorical type only. In fact, much data that has categorical and

numerical attributes exist universally in real life. K-prototype (KP) is

the most popular algorithm for clustering mixed data, because it is

effective for large data. However, k-prototype has several weaknesses,

i.e.: the use of mode at the cluster center for categorical attributes

cannot accurately represent the objects, and the algorithm may stop at

local optimum solution because affected by random initial cluster

prototypes. To overcome the first weakness, we can use fuzzy centroid

and for second weakness is implement genetic algorithm to search

global optimum solution. Finally, To accommodate those two

weaknesses we will combine the genetic algorithm and Fuzzy K-

prototype (GA-FKP). The experiments show GA-FKP has a better

results than FKP according to four indexes to evaluate the clustering

result. Besides that, according to CV index shows FKP and GA-FKP

gives better result than KP.

The cholesteryl acrylate polymer-ITO (CAP-ITO) composite in this

study was successfully synthesized by UV Curing method with

variation of dopant ITO nanoparticle concentration 0, 5, 10, 15, 20, 25,

30, 35, 40, 45 and 50 % w/w. The CAP-ITO composite characteristics

are functional groups and surface morphology identified using FTIR

and SEM. The result of FTIR characterization show a peak shift in the

1658,85 cm-1 which is a stretching C=C. This shows that the CAP-

ITO composite has been polymerized. Reduced hydroxyl and carbonyl

group in the spectrum show an interaction between the cholesteryl

acrylate polymer and ITO. The results of testing the effect of ITO

nanoparticle dopant on the CAP-ITO composite conductivities with

LCR Meter show that the addition of ITO as a dopant in a polymer

cholesteryl acrylate can increase the conductivity of the composite

even when compared to an ITO micrometer-sized dopant. The CAP-

ITO composite with 10% w/w ITO concentration has the highest

conductivity value that is equal to 5,70x10-7 S/m and reach the

threshold value at the concentration of ITO 20% w/w. These results are

also supported by SEM characterization which show an equal

morphological structure for the CAP-ITO composite with ITO 10%

w/w.

Gene's expression data sets provide powerful insight of functional

genomics in life sciences. Here, we used the Maize NAM expression

data sets from Maize Teller and performed the Support Vector

Machine (SVM) to classify the high-dimensional information on gene's

expression based on organ's characteristics: apex, ear, root, shoot, and

tassel. We conducted a filtering process by removing null value and

ANOVA test to reduce data complexity before analysed using SVM

provided in e1071 R package. We used the ratio 70%:30% for training

and testing data set and found the cost value for C=0.1. We evaluated

the SVM prediction using accuracy, precision, and recall functions. As

a result, we found an accuracy rate of 100% for apex, ear, and tassel,

while 88.89% for root and shoot with AUC value = 0.9895. We

obtained the sum of 8,470 genes expression with various weight values

and visualized the gene's expression based on weight value ≥ 0.03.

Hence, we found genes that probably the key players on the specific

metabolic pathway in maize organs.

Digital signal modulation is a way of transforming binary data to

continuous signal so that they could be carried by the signal carrier in a

certain band-pass channel. There are several digital signal modulation

techniques that are often used, they are BPSK (Binary Phase Shift

Keying), QPSK (Quadrature Phase Shift Keying) and QAM

(Quadrature Amplitude Modulation) which are simulated in this study

with Matlab Simulink model. Two parameters are employed to

compare the performance of the five signal modulation techniques in

Multipath Rayleigh Fading Channel: the bit error rate (BER) and the

power spectral density (PSD). Results show that in terms of bit error

rate, BPSK has the lowest rate (2.75e-5), followed by QAM (2.81e-5),

QPSK (2.61e-3), 16-QAM (2.72e-3) and 16-QPSK (6.34e-3). In terms

of power spectral density 16-QPSK ranked first with (55.508 dBm),

came second BPSK (55.561 dBm), QPSK (59.589 dBm), QAM

(66.436 dBm), and finally 16-QAM (89.722 dBm).

A single condensate partition function in the canonical ensemble of the

one-dimensional Gross-Pitaevskii equation has been used to construct

the partition function of N noninteracting condensates. In this paper we

employed the appropriate transformation in order to make the partition

function of a single condensate to be an extensive quantity by

introducing a harmonic volume as the inverse cube of the average

geometric trapping frequency. We found that some expressions of the

thermodynamic quantities must be corrected to keep the consistency of

the thermodynamic expressions based on the Gibbs paradox in the

statistical mechanics. This only can be done if a collection of

condensates is considered as the indistinguishable macroscopic

quantum oscillators with a weak nonlinearity instead of the

distinguishable ones.

outcomes on statistic course. It happened because the college students

admission is not only from the natural sciences department in senior

high school, but also from social sciences, linguistics or from

vocational schools which the mathematic concept that’s taught in

school is not to broad. As a result, there were no strong basic math

skill of college students, which cause the lack of understanding on

statistic concept. Hence, There were the lack of student activities in

class. One of the solutions to solve that problem is by using Student

Teams Achievement Division Learning model. The uniqueness of this

model is about the learning process which emphasize at the student

activities. The research aims to improve the mathematic education’s

college student learning outcomes, university of flores on statistic

course using Student Teams Achievement Division Learning (STAD).

The research approach which used is quantitative research with

research type is classroom action research involve planning, action,

observation, and reflection. The result shows that the college student

learning outcomes of statistic course using student team achievement

devisions learning has increased.

studies in chemistry education report the students’ alternative

conceptions and difficulties in chemistry learning. One of the difficult

concepts for students is electrolyte and non-electrolyte solutions which

many students have misconceptions in understanding the concepts.

This research conducted in a secondary school in Karawang, which

involved 127 of year-10 students in the chemistry classroom. Data

collection was carried out using a two-tier diagnostic test and in-depth

interview. The two-tier instruments were developed in relation to

chemistry curricula, existing kinds of literature, and students’

characteristics, which were validated using construct and item

validation. The study result showed that 18, 31% students have

alternative concepts in an electrolyte and non-electrolyte solution

concept; 16, 54% students have alternative concept's chemical bonding

and its impact for electricity, and 16.01% students have alternative

concept's phase of a compound and its impact for electricity. This

result indicates that the students' alternative concepts were influenced

by students' experiences, teachers’ language, the textbooks, and

students’ thinking process in developing their knowledge. Therefore,

it’s important for the teachers to understand students’ alternative

concepts and thinking process and to overcome these challenges.

The research was conducted to reconstruct molecular engineering

activity for chemistry teacher education through interactive simulations

on cellulose dissolution in ionic liquids as “designer” solvents. This

activity is aimed to enhance the View of Nature of Science and

Technology (VNOST) of the pre-service chemistry teacher. This study

refers to the Model of Educational Reconstruction (MER) with stages:

(1) analysis of content structure, (2) research in learning, and (3)

development of learning design. The instruments used were text

analysis form, validation form, interview guidelines, VNOST

questionnaire, expert assessment form and the test items available in

the interactive simulation program. The questionnaire and interview

were conducted to 20 pre-service teacher from the third

year. According to the scientific perspective and the results of the

validation of learning outcomes, the chemical concepts related to the

topic of ionic liquids as cellulose solvents are ionic bonds, forces

between particles and polymers. The results of the interviews as

preconception data indicated that the topic of ionic liquids as cellulose

solvent is new to students but some students can relate them to the

related chemical concepts after analyzing illustration pictures and

The Neutralization Model on an Empty Number Line for

Integer Addition and Subtraction

Puspita Sari, Swida Purwanto, Mimi Nur Hajizah



Studies indicated that the use of models and contexts could support

students’ thinking in performing addition and subtraction of integers.

Researchers suggested that the use of number line model could be

helpful for supporting integer addition. Others found that the number

line should be avoided in integer subtraction, and hence the

neutralization model was offered as an alternative. However, the use

of neutralization model also gives another conflicting problem for

students. Therefore, a combination of the two models is introduced in

this research, namely the neutralization model on an empty number

line, so that students can apply the procedure of the neutralization and

draw their strategies on the number line at the same time. The purpose

of this study is to contribute to the instructional theory on integer

addition and subtraction as well as to improve teaching and learning

practice. Design research methodology was used by designing an

instructional design, conducting the lessons, and then analyzing how

the learning process took place as well as how students engage during

the lessons. The results showed that the use of context and

neutralization model on an empty number line could give meaning to

students that subtracting a negative means adding a positive.

Laboratory work is the core of learning chemistry. Research showed

students who are well prepared for laboratory classes and possess high

competency in laboratory skills are more likely to gain the maximum

possible benefit from the laboratory learning environment. Therefore,

the video of laboratory skills and techniques was developed in order to

deliver prior knowledge to the students regarding laboratory skills

needed in the basic chemistry experiment course. Basic laboratory

skills video adapted the Kemp model as instructional design models.

Cognitive Conflict activity was added by applying “do” and “don’t”

strategies in the video. First, the video presents the common mistakes

in doing laboratory skills, which pays special attention and induces

cognitive conflict to student’s prior knowledge. Then, the appropriate

laboratory skills are displayed in the following section which remains

of the topic to be more lasting. It is hoped that facilitated video in pre-

laboratory phase can be an aid to reduce and avoid from the potential

mistake laboratory skills and do the practical lab effectively.

However, teaching and learning activities at PKBM is not yet feasible.

In this article, we report the case study results by giving algebraic test

for students. The aim is to observe at students' algebraic abilities and

matching the difficulty found with the type of difficulty based on

AVAE theory. First, we given algebraic test for the students from the

national exam of equality paket B last year. Next, we analyzed students

results and matched students answer based on the types of algebraic

difficulties in AVAE theory. We found that students ' abilities of

algebraic operations are still very low and students' difficulties in

answering algebraic test correspond to the types of algebraic

difficulties in it. These findings suggest that students' algebraic

abilities need to be a major concern for improvement and the

difficulties that exist in students are not much different from the

findings gained in the results of research that created the AVAE

theory. For further investigation, we consider to examine the problem

designed based on the difficulties put forward in it on students of

In Indonesia, oil palm plants are one of the most consumed and

produced palm oil plants in the world, reaching 36,000,000 tons out of

a total of 58,800,000 tons of production in the world. This causes oil

palm as the largest foreign exchange earner in Indonesia. However, the

growth of palm oil is inhibited by palm leaf-eating pest insects, one of

which is a caterpillar pest or nettle caterpillar which has the potential

to eliminate about 35% of the total palm oil production in Indonesia or

about 6.4 tonnes per hectare. The purpose of this study is to monitor

the presence of nettle caterpillar with Raspberry camera remotely. The

monitoring includes object detection of nettle caterpillar species. This study uses nettle caterpillar image collection taken from internet

as training data sets and real nettle caterpillar as testing data sets. The

real-time image captured from our custom device is then identified.

The results of this identification can be used to determine the exact

quantity of pesticides to be provided according to the growth of the

pest insect. The anticipated outcome of this research is the

identification of the nettle caterpillar that affects oil palm growth. The

findings may be useful in reducing the usage of pesticide.

Appreciating the dynamics of policies on innovation partnership

networks is critical to policy developers and effectors. We adopt a

time series data to develop a set of dynamic networks that reflect the

structure and quality of innovation relations that develop and fizzle-out

as specific reforms are applied to innovation partnerships. Industry-

specific policies are also considered in relation to the period under

consideration. Using specifically selected attributes of the networks,

we examine the variations as a means of extrapolating the impact of

policies on the innovation network. The degree of change in the

gradient of structural holes of the networks per period was used to

showcase how individuals within the network are being impacted by

the policies over time. The evidence shows that the structure and

individual attributes have a direct impact on the innovation networks

ability to generate research or commit to research funding. These

Findings indicate that national policies affect the evolution of

innovation networks while influencing the desired aims of partnership

formation in such evolving systems.

Innovation partnerships provide the unique landscape that facilitates

the production, diffusion and adoption of innovation. The adoption

probabilities of individual enterprises within the innovation space are

influenced by external and internal forces and are susceptible to

imitative behavior of competitors and the number of competitors

adopting the innovation. Dynamically, this determines the

sustainability of the adoption process and, possibly, the likelihood of

future adoptions. Using a network approach, we empirically tested the

impact of the influencers on the innovation adoption process within

University-Industry networks and concluded that the life span of the

innovation process is strongly affected by the conditional influencing

factors that determine the adoption behavior of enterprises within

industrial networks.

In this paper, a new model for kriging as predicting spatial value of

circular random fields at non-observed points from a collection of

circular spatial data observed at several locations. This model employs

a median-polish algorithm for circular data. Median-polish algorithm

for circular data is used to remove the trend in circular spatial data.

Removing the trend in the circular spatial data is required to meet the

stationarity assumption prior to predicting circular spatial value using

circular ordinary kriging method. The new model is evaluated on

simulation and real-world data sets. Leave-one-out cross validation is

used to evaluate performance of the new model. The mean absolute

cosine error (MACE) and mean cosine difference error (MCDE) as

two metrics are used to measure the performance of the new model.

The experiments on both types of data sets i.e. simulation and real-

world data sets show that the new model can be considered as a

promising tool for predicting value of circular random fields at non-

observed points.

MapReduce is a programming model and a runtime environment for

big data processing over distributed systems (e.g., Cluster, cloud and

grids). In addition, the task failure has become a critical issue and

could increase the cost of the job and affect resource utilization in

MapReduce. Currently, MapReduce fault tolerance mechanism is

based on rescheduling failure tasks on other nodes, which will be re-

executed again, and this rescheduling affects resource utilization, as

well as, execution time. In this paper, concerning MapReduce fault

tolerance, a new Rollback-recovery model called Pessimistic Log-

based Rollback (PLR) is introduced. The central principle of the

proposed PLR model is a logging process to enable rollback by

recording the task, which is determinant in the log report when the

failure occurs. When a task is failed, the proposed PLR model will reactivate the execution of this task starting from the last state before

failing on the same node which optimistically can solve the

MapReduce task failure problem. In the worst case, the task will be

rescheduled into another node to be re-executed. The experimental

results of the proposed PLR model show that MapReduce performance

is improved in the case of failure by reducing the execution time by

35% approximately.

Consider a new repairable system, for example a production machine,

that starts to operate at time 0. After some amount of time, the system

fails. Soon after the failure, the system is repaired perfectly so that the

system functions like a new one. After operating again for some time

the system fails, and then the perfect repairment is performed. This

process goes continuously. We assume that the operating time, and the

repair times are random. When the system is in operation then it

generates some income, which depend on the length of the operation

time. On the other hand, when the system is repaired then the

maintenance cost is incurred, which is also depending on the length of

the repair time. So, during the time interval [0, t] the system generates

the total profit which is equal to the total income minus the total

maintenance cost. In this paper, we discussed a method for computing

the expected profit of total profit generated by a repairable system.

This work presents a method based on the Generalized Auto-

Regressive Conditional Heteroskedasticity (GARCH) model to

determine structural breakpoints in volatility of a time series. In many

time-series models, volatility is approximated to be constant over a

period of time or moving from one regime to another. In such cases, it

is important to determine when shifts in volatility patterns occur. The

model is used to identify periods of high and low volatility, and to

assess the long-term volatility of time series. The method is then

applied to the Philippine Peso-US Dollar currency exchange rate. The

results agree with events in Philippine history indicating periods of

economic instability.

Monitoring the spread of diseases, especially with very high levels of

dissemination, is urgently needed by researchers, practitioners, and

policymakers in the health sector, in order to make accurate decisions

as quickly as possible. In such efforts, the availability of a spatial-

temporal information system capable of monitoring the spread of

disease in a particular geographic location over a period of time is a

vital necessity. A system can be which able to provide clear

information, in which areas disease spreads and how far its extent is

spread, so policymakers will be able to predict the pattern of spread of

the disease and as early as possible to identify areas vulnerable to

infectious diseases. There are various spatial-temporal models that have been developed today: Space-Time Autoregressive Moving

Average (STARMA) model, Space-Time Autoregressive (STAR)

model, Generalized Space-Time Autoregressive (GSTAR) model and

GSTAR model development, Generalization Space-Time

Autoregressive model -Kriging (GSTAR-Kriging). To find out where

the disease was found and when it occurred, how many victims, and

how many died, then used a spatial-temporal model. The Data

observed in this study only comes from one region only, so the

problem is limited to models in the order of 1 in time lag and order 1

for spatial lag. Data used in this research is data of dengue fever

patient in Makassar City 2017. So for the locations that are not used

samples used GSTAR-Kriging modeling by borrowing data inter

Big data streaming is the most trending term nowadays, collecting a

stream of data from different places and devices needs to be processed

in real time. Hadoop is the suitable framework for this large stream of

data because it supports handling of big data as storage in HDFS and

real times processing with map-reduce functions. Big data streaming

needs a security model to achieve data confidentiality. According to

the work in this paper, a comparative study has been done among

different security approaches (i.e., block, stream, and hybrid) which

have been applied for Hadoop. The implementation of these

approaches is based on the performance and the output data for each

approach. The results of the comparative study show that the streaming

The stock market is a vital area of research due to its higher earnings,

which. Consequently, implies to higher risks, so a large amount of data

generated by the stock market is considered a treasure of knowledge

for investors. Although there are several aspects that affect the stock

market fluctuations, however, the most important of them is news data.

News data have an influential effect on the investors' thoughts and

beliefs. Applying machine learning and textual data processing is

considered a significant approach of the stock market analysis. Many

researchers have focused on the strong relationship between stock

news and changes in the stock prices. Following this direction, this

study proposes an intelligent framework which focuses on two main

directions, first detecting the stock market fake news that helps in

avoiding the higher investment risks, and second, improving the stock

market prediction accuracy. The proposed model aims at discovering

the best combination of machine learning algorithms that lead to the

best performance of the prediction model based on news sentiment

analysis and numeric data analysis. Different experiments have been

applied to uncover algorithms that guaranteed the highest performance

and raised the prediction accuracy by up to 92%.

Questions given to students to identify their understandings after

learning, particularly chemistry learning generally only follows what is

presented in lectures and textbooks, which commonly provide just one

solution to each problem. The emphasis on Higher-Order Thinking

Skills (HOTS) question type is generally less concerned. However, the

crucial role of teaching and evaluation of HOTS in science education

such as critical thinking and problem solving has been confirmed from

much literature. HOTS, such as critical-thinking skills and problem-

solving ability are essential for future study and employability because

this type of question will challenge students to think deeply and

critically. This study aimed to identify Indonesian students’ HOTS in

solving chemical kinetic's questions. 379 chemistry students from

Haluoleo University participated in this research. Students’ HOTS was

assessed by using Chemical Kinetics HOTS Instrument in the form of

pictorial and algorithmic type questions. By comparing students’

answers to both types, students’ HOTS is revealed. This study shows

that students’ HOTS is not as well developed. In some questions, only

a small number of students gave analytical answers. It seems that

Indonesian students are not familiar with questions that demand

critical-thinking skills to be solved.

Anticipating students’ responses is an important element in planning a

lesson. This involves teachers’ knowledge of the mathematics taught

and knowledge of the students. This paper discusses pre-service

teachers’ anticipation of students’ responses in a lesson study context.

The lesson study was embedded in a teaching practice program at one

university in Jakarta. It was conducted at two lower secondary schools

in Jakarta, involving seven pre-service teachers, three mentor teachers,

and two university lecturers. The researcher took the role of the

knowledgeable other in the lesson study. Using case study

methodology, data were collected through written test, video of the

lesson study meetings, and interviews. The findings showed that the

pre-service teachers’ anticipation of students’ responses was vague and

lacked details. In making the anticipation, the pre-service teachers

considered students’ previous learning and characteristics. In

teachings, having the anticipation of students’ responses did not help

the pre-service teachers to handle contingent moments. The pre-service

teachers needed handy prompts to respond to students’ questions. The

pre-service teachers found that anticipating students’ responses was

difficult but rewarding. Despite the extra detailed work, anticipating

students’ responses helped the pre-service teachers plan the lesson

better and improved their confidence.

Moslem-oriented schools have attracted some Indonesian researchers

to study how students learn and think mathematically. This paper

addresses the process of translation among mathematical

representations from both male and female students in Madrasah

Tsanawiyah Negeri II Surabaya Indonesia. From nine classes, only the

8th-D grade students were involved in this study. Twelve boys and

fifteen girls completed the BSRI’s questionnaire, the maths’ ability and

open-ended translation–representation tests. There was one

androgynous with high maths’ ability, 2 masculines of five students

with medium, and 21 students (2 masculine, 4 feminine, 7

androgynous, and 7 undifferentiated) with low maths’ ability,

respectively. One masculine and one feminine, from medium students,

were volunteers selected to be detail interviewed, based on their maths’

representations answers. Data were analysed through four translation

processes. In general, all students demonstrated all translation stages

improperly. However, feminine perform better than a masculine

student in implementing translation from source to target

representation. Related to translation from symbolic to visual and

verbal to visual, masculine performed less compatibility in making line

graphs, due to carelessness in writing coordinate axes. This study

emphasizes that translation mathematical representations need to be

strengthened for students in supporting their understanding to learn

new mathematical concepts.

the perception of present curriculum from the contextualization

perspectives?’ If the curriculum is not/contextualized, then why? What

are the steps to be taken to make our curriculum? contextual? And

what are the advantages of contextual curriculum? On the respective

questions respondents focused that our curriculum became traditional.

Students’ achievement is marked by their scores in the summative test.

Curriculum is not contextualized. Much content which is taught in the

classroom are not getting its applicability in their field other then

teaching inside the classroom. Curriculum should focus the need of the

students. They need to stand on their own feet after they pass the

certain level exams. Our curriculum has not been able to teach the

morality matter to the students. These matters were focused by the

respondents on their paper, as well as in the communication. Further,

applicability of curriculum and Individual efforts of the students

should be encouraged and credited, are the pivotal parts of the project.

analogies

Joshua S. Soldivillo and Nelson A. Rosaroso

Bacong, Negros Oriental, Philippines 6216


This study aimed to develop a teaching-learning sequence (TLS) on

normal force, surface friction force, and tension force using bridging

analogies (Camp & Clement, 2010) and investigate its effect on

students’ conceptions to promote conceptual understanding. This is so

since traditional methods of physics teaching do not usually consider

students’ debilitating alternative conceptions; thus, failing to

engender conceptual change. Hence, a Type-3 developmental

concurrent-nested mixed method's research design was used in which

the target alternative conceptions on the three forces were based from

the literature, and the quantitative data set provided a supportive role

to the qualitative data. The quantitative data included a conceptual

inventory to determine students’ initial and final conceptions. The

qualitative data gathered from focus group discussions, journal

entries, activity sheets, and voting sheets helped in describing

students’ conceptual changes. The study involved intact

heterogeneous General Physics 1 class of Grade 12 STEM students

(n=44). The results revealed that there were correct and incorrect

conceptions before and after the implementation, and that the

bridging cases were successful in promoting conceptual change. The

study also affirmed the resistance of alternative conceptions, which

harbor among students.

This study investigated the incorporation of a formative assessment

strategy called the Novel Written Task (NWT) in Physics instructions

and its impact on the cognitive learning achievement of seventy eight

Grade 10 students. The researcher designed 5E lessons with embedded

assessment activities for three physics modules, namely, Electricity

and Magnetism, Electromagnetic Spectrum, and Optics. Three physics

experts characterized the assessment activities as a rich tool in

assessing students’ knowledge and conceptions. Achievement tests and

short quizzes measured the effect of the intervention throughout the

course. The NWT results revealed low consistency in students’ factual

knowledge and reasoning, their misconceptions, common errors, and

over generalizations. The students exhibited significant learning gains

during formative and summative evaluations wherein small to large

effect sizes were determined. Findings also revealed meaningful

improvement in the higher-order cognitive process skills of the

Motivation

Tolentino, Analyn N., Roleda, Lydia S.

De La Salle University, Manila


Gamification is the incorporation of game elements in non-game

contexts. This study explored the effects of a gamified instruction to

the motivation of high school students in Physics. The framework of

the study is anchored on the Self-Determination Theory which claims

that humans are inherently active, inquisitive and self-motivated even

without external reward. However, extrinsic motivators can be

converted to intrinsic motivators if they are meaningful, pleasurable

and consistent with a person’s world view. To determine if

gamification has a significant effect on the student motivation, the

students’ responses to the pre-gamification and post-gamification

administration of the Physics Motivation Questionnaire were compared

using the paired sample t-test on SPSS. Results showed that gamified

instruction brings about a significant increase in student in student

motivation. Feedback coming from students, teacher-implementer and

external observers substantiate the influence of gamification to student

motivation. The technique was found to be fun and enjoyable,

rewarding and highly motivating for students. It fosters positive

attitude toward learning and towards assessment. However,

implementation must be done with utmost caution so that no unhealthy

competition develops. With proper execution, no student should

become extremely grade conscious that he or she ends up resorting to

cheating. This way, an environment conducive to learning is

maintained inside the classroom.

Teacher Support Material in Physics for the Explicit-

Reflective Instruction of the Nature of Science Leading to

Scientific Literacy

Mylha H. Baltazar and Marie Paz E. Morales

Philippine Normal University


Nature of science (NOS) is one of the components of scientific literacy

that is poorly represented in science curriculum materials in the

Philippines. Thus, the main goal of this study was to find out how the

nature of science (NOS) would develop scientific literacy through the

developed teacher support material (TSM) for the explicit-reflective

instruction of the nature of science for K to 12. The student

understanding of scientific inquiry (SUSSI) revealed that both the

student- and teacher-respondents held naive views on scientific laws

vs. theories and social and cultural influence on science. Based on the

findings on NOS views, a teacher support material was designed,

developed and validated. The material was implemented to Grade 9

students where the participants demonstrate unchanged level of NOS

literacy however, test of basic scientific literacy’s (TBSL) test of

knowledge of the nature of science reveals that it still appears that the

TSM can change the students’ NOS views. On the other hand, the use

of TSM was effective in enhancing the scientific literacy of students.

Suggestions for further studies were made which include the use of

explicit-reflective instruction of NOS in the present curriculum as an

innovative approach of promoting common and accurate views of NOS

in science classrooms.

The composites of cholestyl acrylate-ITO polymer (PKA-ITO) in this

study have been successfully synthesized by UV Curing method with

variations in the concentration of cholesteryl acrylate 0.04M monomer;

0.08M; and 0.16M. Characteristics of PKA-ITO composites in the

form of functional groups, X-ray diffraction patterns, crystal

properties, and surface morphology were identified using FTIR, XRD,

and SEM. FTIR characterization results indicate a peak shift in a wave

number of 1624.061632.53 cm-1 which is a stretching group C = C.

This shows that the PKA-ITO composite has been polymerized. Shifts

also occur at wave numbers 1600-1750 cm-1 which are stretching

group's C = O. This shows the interaction of ITO with cholestyl

acrylate in PKA-ITO composites. The XRD characterization results of

PKA-ITO composites showed X-ray diffraction peaks at 2 = 2.0200o;

5,2800o; 8,2188o; 16,4721o; 30,7321o which is a typical ITO peak

and a typical peak of cholesterolil acrylate. This shows that the PKA-

ITO composite has a crystalline phase. These results are strengthened

by the results of SEM characterization, which shows a uniform and

uniform morphological structure for PKAITO composites (0.08M

This study aims to improve elementary school students' understanding

of light concepts through implementation of the Learning Cycle 5E

model. The research was conducted in the second semester of the

academic year 2017/2018. The participants were students of thirty-five

of year-5 students. This study employed qualitative approach with data

collection techniques of interviews, reflective journals, classroom

observation and test concepts. Classroom observations and interviews

were conducted before and after implementation of the study to

understand the students’ characteristics and the classroom learning

environment. While the interview conducted after the learning process

to explore the students' conceptual understanding of light concepts.

The data were analysed and represented through the key concepts in

learning light topic. The results showed that fifth-grade students based

on the student test on the properties of the light and the optical

instrument project which is generated two categories of good

understanding and limited understanding. There were 85,2 % students

who have good understanding of the concepts and 14,8% of students

who have limited understanding of the concepts. Students express their

ideas through discussion and collaboration. Therefore, the students

have developed good understanding and collaboration through the five

steps of learning cycle 5E.

Keywords: science learning, light concept, learning cycle 5E

Pre-Service Teachers’ Misconception on Acid-Base through

the Analysis of Laboratory Jargon

Tritiyatma Hadinugrahaningsih*, Achmad Ridwan



This study aims identifying pre-service teachers’ misconceptions in

acid base through Laboratory Jargon analysis. The Laboratory Jargon

as the statement by experts which use in teaching can lead to students’

misconceptions. The study employ survey as a methodology which

involved 216 pre-service chemistry teachers from the pedagogical

university. The data collection of Laboratory Jargon instrument,

interview, and observation. The instrument of laboratory jargon is

developed based on the Broensted’s theory with 10 multiple-choice

problems (Barke & Joline, 2018) consist of acid base concepts on

atoms and molecules, acid base theory, water dissociation, weak acid-

base, water concentration, formation of acid-base ions, neutralization

reaction; acid strength (pH), acid base indicator, and amphoteric properties of water. The results of the study show that the pre-service

teachers hold the misconception on all the concepts. The average

49.2% pre-service teachers provide the misconceptions answers on the

questions. The four lowest percentage of pre-service teachers’

misconception are on the formation of acid base ions (32%),

amphoteric properties of water (31%), neutralization (21%), and acid-

base theory (19%). Based on following depth interviews and

observations, there are large number of the pre-service teachers who

use the Laboratory Jargon to understand the acid-base concepts which

lead to misconceptions in understanding of the related concepts.

Keywords: pre-service teachers, Laboratory Jargon, chemistry,
