settlement process. Stilt houses and riverside settlements

include vernacular architecture. This house is aligned and

adaptive to the Musi River natural environment. The

magnitude of the potential of traditional houses is less

realized by the rapid changes that marked the emergence of

new forms the more abandoned form of traditional homes.

There are three vernacular settlement modes that have been

living for centuries by the people of Palembang in addressing

the Musi River that is the Raft House settlement on the Musi

River, then the tidal settlements with their stage houses on the

pole (Limas House and Limas Gudang House), and

settlements land. Raft houses are now getting smaller and

disappearing from the banks of the Musi River, houses on

stilts and houses at the bottom of the moon turned into a

dwelling because the conditions are dry and changed the

function leads to the pattern of living land. This study used a

qualitative approach with a case study strategy, aimed at

identifying the existence of vernacular settlements in 3-4 Ulu

and 30 Ilir Palembang. Data were collected from six main

sources, namely documentation, archival records, interviews,

direct observation, participant observation, and physical

artifacts. The findings of riverside settlements still show their

existence among the new houses and riverside settlement.

Neighborhood Relationship Among Villages in

Jabung District, Malang Regency:

Multidimensional Poverty Approach

Ismu Rini Dwi Ari

Brawijaya University of Malang, Indonesia

Corresponding email: [email protected]

Currently, poverty does not only measured by single

economic aspect, but also covers a much wider range aspects

of life. Poverty can emerge to the community when the

community have no basic abilities, have no income, not

served adequate education, have a bad health condition, feel

not safe, have low confidence or lack of rights such as

freedom of speech. This research takes place at Jabung

District, Malang regency that is characterized with 35%

households identified as poor household that is spread within

their 15 villages. In order to deal with poverty alleviation,

main research aims are to i) measure multi-dimension poverty

index and ii) scrutinize neighborhood relationship among

vilages. There are two research methods are used i)

Multidimensional Poverty Index (MPI) - covering three

dimensions (health, education and living standard) and ii)

Spatial Data Analysis, wherein data collection has been

conducted through field observation as well as face-to-face

questionnaire survey. Estimation result of the MPI, it is

identified that among 5 poverty level there are 4 poverty

level: high - medium - low - very low covering 5, 5, 2, 3

villages, respectively. Hence, based on the MPI measurement,

there are five villages with high value as the targeted area on

dealing with poverty alleviation - Jabung (0.34), Taji (0.31),

Kemiri, Gunungjati and Slamparejo with value of 0.29. In

addition, result of LISA map by spatial data analysis indicates

that cluster of High-High is form by village of Kemiri and

Slamparejo. It is assumed that when poor village have nearest

physical border with another poor village, it will be more

difficult for the villages to move out from poverty condition,

so that the poverty alleviation program should focus upon

those areas.

Double Layered Home-based Enterprises: Case

Study in Kampung Lio, Depok

Farrah Putri, Joko Adianto, Rossa Simatupang,

Indonesia University, Indonesia.


Struggling to fulfills economic needs in between rapid growth

of urbanization, one of the trend happened in Kampung Lio,

Depok, Indonesia is to rely on informal economic activities

such as HBE (HBE). As HBE become an important topic in

informal housing and economic activities, the existing

literature has discussed HBE and its implication to spatial

strategies. However, in Kampung lio a unique case has risen

where the locals are renting HBE for another layer of HBE,

making a double-layered HBEs occurred in one housing. By

doing site observation and empirical data collecting, this

research aims to examine how the locals using a certain type

of HBEs until the double-layered HBEs emerged. The

expected results are to understands how the houses are

modified and the activities pattern as they adapt to the change

of living spaces in a double-layered HBE in Kampung Lio.

This later could be used to serve as the inspiration to

designing low-income housing with home base enterprise and

public spaces in the urban kampong.

The Shift of Zoning in the Architectural Adaptation

of Stilt House

Widya Fransiska Febriati Anwar1 , Zuber Angkasa2

Indonesian's society has character as collective society

because of the stronger group interest than personal interests.

It is reflected on the architecture of traditional stilt house

particularly on its space order. However, the modern life

brings the concept of individualism in the society and some

changes in space order of stilt house. This paper aims to

understand how the stilt house adapts to the space demand in

responding the collective culture in current context. Study

hypothesize that there is a change in applying the collective

culture that influence the adaptation of the stilt house. In

order to achieve that, this study observed the space used of

nine old stilt houses in Palembang which were built in the

period of 1928 to 1964. This study used the theory of

collectivism and individualism to examine the origin and

current space usage. Paper founds most of stilt houses use the

space under the stilt structure as a part of its inner space.

Furthermore, that there is a shift in the zoning of the space

under the stilt house. For first use, the space change from

collective function to individual as it bordered the space as

inner side the house. Then the bordered space was arranged

as public zone, shifted again to the collective function. Paper

concludes that the shift reflect the life orientation changes in

the society.

The building performance of Palembang’s

traditional houses

Widya Fransiska Febriati Anwar

Sriwijaya University of Palembang, Indonesia


As one of old city in Indonesia, Palembang has some

traditional houses at its old area. The houses are still occupied

by modern people. The modern lifestyle threatens the

authenticity of the houses as the occupants tend to change

them. They change the design of the house to get the

performance of the building to be in line with their activities

and lifestyle. Paper aims to know the building performance

traditional houses in Palembang. To achieve the aim, paper

examined the natural lighting performance of three types of

traditional houses in accommodating the visual comfort for

current activities. The analysis of performance was done

through the simulation of lighting performance. The result

shows that the houses have different ability to accommodate

the visual comfort. Paper shows that the changes need to be

done to accommodate the current need of natural

illumination. In order to maintain the authenticity, the change

can be done by adding openings at building skin and roof.

Microwave Assisted ZnCl2 Activation of Salacca

Peel Derived Activated Carbons as Adsorbents for

Cu(II) Removal from Aqueous Solution

Arenst Arie

Parahyangan Catholic University, Indonesia


In this present study,salacca peel based activated

carbons (SPAC) were prepared by microwave assisted

ZnCl2 activation method. The effects of microwave

power, activation time and impregnation ratio on the

characteristics of activated carbon were studied. The

activated carbons were characterized by N2 adsorption-

desorption and scanning electron microscopy (SEM)

instruments. The BET surface area of 1796 m2/g were

obtained at a microwave power of 540 W, activation

time of 25 minutes with an impregnation ratio

(ZnCl2:salacca peel) of 4:1. The resulting activated

carbon was used for removal of Cu(II) from aqueous

solution. The prepared activated carbons were then

used as adsorbents for removing Cu(II) metal ions from

aqueous solutions. The adsorption equilibrium was

investigated using using Langmuir, and Freundlich

model equations. It was found that the adsorption

equilibrium data followed the Langmuir isotherm

equations with maximum capacity of 1262.62 mg

Cu(II)/g SPAC at room temperature. The adsorption

kinetics were also studied using the pseudo first order,

pseudo second order and intraparticle diffusion models.

The adsorption kinetics was shown to fit well with the

pseudo second-order kinetic model.

Monoglyceride and Monoglyceride Derivatives from

Glycerol Generated in Catfish Based Biodiesel

Production Process

Hue Bui, Jr

Campus II, 3/2 Streeet, Ninh Kieu, Can Tho, Vietnam


Glycerol is a major byproduct in the biodiesel

manufacturing process which causes environmental

problem since glycerol cannot be released without

treatment. In this study, crude glycerol was refined into

a pure form by using phosphoric acid. Esterification of

the purified glycerol with oleic acid afforded glycerol

monooleate in 43% yield using p-toluenesulfonic acid

as a catalyst. The obtained glycerol monooleate was

then allowed to react with lactic acid, acetic acid or

diacetyl tartaric acid to provide the corresponding

lactylated, acetylated or diacetyl tartarylated glycerol

monooleate, respectively, in reasonable yields. These

ester derivatives of monoglycerides have been known

to be the most commonly used food surfactants.

Utilization of PT. HOK TONG Liquid Waste

Rubber Industry in Making of Liquid Organic

Fertilizer with Addition of Eceng Gondok and EM4

(EFFECTIVE MICROORGANISM 4)

Farida Ali, Farida Ali, Tuti Indah S, Arina, Switri



The liquid waste of the rubber industry is currently not

fully utilized, whereas the industrial rubber waste is the

nutrient needed by plants, especially nitrogen (N),

phospate (P2O5), and potassium (K2O). The presence

of macro nutrients contained in the liquid waste of

rubber industry is expected to be an alternative material

for the manufacture of liquid compost. Water hyacinth

is a plant that also contains a good macro nutrients for

plants, so it can be used as an additional material to

improve the nutrient elements of liquid compost

fertilizer. This research aims to know the utilization of

industrial rubber waste in the manufacture of liquid

compost fertilizer with the addition of water hyacinth

and EM4. The method used in making this liquid

organic fertilizer was anaerobic fermentation process.

The variables studied were addition of water hyacinth

and volume of EM4 added. The results of fermentation

were analyzed to obtain data of percentage of nitrogen,

phosphate, and potassium content. Obtained results of

liquid compost fertilizer, with the largest nitrogen

content is 1.6% found in EM4 25 mL and water

hyacinth 30 gr, the highest percentage of Phospate

0.160% found in liquid compost fertilizer with addition

of water hyacinth as much as 20 gr and EM4 25 mL,

highest percentage of Potassium equal to 0.358% is

found in water hyacinth as much as 25 gr and EM4 25

mL.

Ultrafiltration of Oil-In-Water Emulsion Stabilized

with Surfactant.

Nita Aryanti

Diponegoro University, Indonesia


Application of ultrafiltration membrane in separation of oil-

in-water emulsion has a consequence of fouling formation

and relate to significantly flux reduction. Filtration of oil-in-

water emulsions is challenging since both oil and surfactant

have interaction with the membranes. In addition, there is a

possibility of droplet deformation to enter the membrane

pores. This research was focused on the effect of surfactant

type on the ultrafiltration performance. Models of oil-in-

water emulsion consisted of crude oil, diesel oil and lubricant

oil as dispersed phase and mixture of distilled water with

addition of 0.1% of Tween 80 or Alkyl Benzene Sulfonate as

the continuous phase. Flat sheet Polyethersulfone having 10

kDa molecular weight cut-off was selected as the membrane.

The result showed that there was fluxes decline during 2

hours of operation in ultrafiltration of oil-in-water emulsion

stabilized with non-ionic surfactant (Tween 80). On the other

hand, when oil-in-water emulsion was stabilized with anionic

surfactant (Alkyl Benzene Sulfonate), the fluxes were

relatively constant during 2 hours filtration. The COD

rejection was in the range of 98-97%, 94-96% and 90-94%

for oil types of crude oil, diesel oil and lubricant oil

respectively. Total oil content rejection was found as 98-99%

for both crude oil and lubricant oil and 98-97% for the diesel

oil. Based on Scanning Electron Microscopy, images of

Saponin extract from pericarps of Sapindus rarak DC is

utilized to replace synthetic surfactant in the surfactant-

enhanced ultrafiltration process. The process conduct to

treat real batik wastewater. The extraction by

maceration methods was performed in various ratio of

solute to solvent. The extract with proper calculation is

used in the wastewater treatment process in various

CMC concentration. The highest yield is obtain at

solute to solvent ratio of 1:40 (w/v). The flux value of

solution without saponin is higher than the one with

saponin addition. The flux value is decreased by the

increase of saponin concentration on the feed solution.

The lowest average flux value of 31.35 L/m2.h was

obtain from the feed solution with saponin

concentration of 2 times CMC. Both process with and

without addition of saponin exhibit permeate flux

declined over time. This is due to the interaction of

saponin molecule with the pollutant where the pollutant

is covered by saponin molecules. The membrane

performance shows that saponin is successfully worked

to solubilize or bounded the heavy metal molecule,

dyes molecules, and other pollutant on its micellar

structure. This is prove by the decrease of Cr and COD

concentration after the ultrafiltration process enhanced

with saponin. Saponin at concentration of 2 times CMC

giving the best result with lowest Cr and COD

concentration of 18.3 ppm and 108.4 ppm, respectively,

and highest rejection of Cr and COD of 95.88% and

One area that is developing in Indonesia is in the area of

textile industry. These industries absorb a lot of labor and

contribute to the country's foreign exchange but have a

negative impact in the form of wastewater produced. The

wastewater produced generally contains synthetic dyes such

as Reactive Red 2 (RR2). This synthetic coloring material

will pollute the environment if it is not well treated first

before being discharged into the environment. In this study,

RR2 will be used as a pollutant model. RR2 will be treated by

several methods. Pollutant concentration is an important

parameter in determining the most appropriate treatment

method. The purpose of this research was to study the effect

of RR2 initial concentration on reducing COD and color

using Fenton, Fenton/TiO2, Fenton/UV, and

Fenton/TiO2/UV methods. RR2 concentration was varied

between 150-300 ppm. As the results, RR2 concentration

from 150-300 ppm does not significantly affect the

percentage of color degradation. However, at high

concentration of 250 and 300 ppm, the percentage of COD

degradation decrease by increasing concentration of RR2.

When using 150 ppm of RR2, the highest COD and color

degradation of 98.8 % and 89.5 %, respectively were

achieved by using the Fenton/TiO2/UV methods.

and the lack of petrodiesel feedstock sources becoming a

problem that can not be ignored. Therefore, to overcome

these problems researchers developed alternative fuels that

are environmentally friendly such as biodiesel. Biodiesel is

produced through a transesterification reaction that reacts

vegetable oils or animal fats with an alcohol assisted using an

alkaline or acidic catalyst. This research was conducted to

find out the influence of catalyst type, molar ratio of alcohol

and fat, and transesterification reaction time to the yield and

the characteristics of biodiesel produced. The

transesterification reaction takes place at 65°C, and the

catalyst weight is 1.5% by weight of beef tallow. Variations

of catalyst type are NaOH and MgO, methanol molar ratio of

6:1, 9:1, and 12:1, and transesterification time for 1 hour, 2

hours, and 3 hours. The results showed that the optimum

commercial ferry in Indonesia is Palembang - Bangka

trajectory. In 2013, there was displacement of

Palembang ferry port from 35 Ilir port in central of

Palembang to Tanjung Api-api port in the countryside

of Palembang to improve ferry service quality. The

displacement reduce travel distances of the ferry from

92 miles to 30 miles. This paper discusses analysis of

the effectiveness of port displacement by analysis of

operating expenses of the vessel, load factor, and the

feasibility of fare. The results showed that operating

expenses of vessel decreased by 9.09% after

displacement. Load factor of passengers and vehicles

shown increasing as well as the production. The

analysis shows the minimum fare become decreasing

proportionately with reducing of travel distance. With

that result, the displacement is an appropriate way to

improve the quality of Palembang ferry services.

Road as infrastructure should be able to serve the flow of

movement of seizure caused. In further review, the current

movement has resulted in poor service levels and congestion

of the road leading to the city center of Malang. Land use

change is evidently authorized by the local government,

which makes the area along the main streets of the city as a

regional trade and services. The purpose of the research was

to identify the characteristics of the main road network, to

identify the characteristics of land use, and to formulate a

model of generation/attraction of land use in the main road

network, to formulate a model of the interaction of land use

and road network. It is expected that the interaction model

can estimate the important actions related to the influence of

land use on the level of service. The research used Pearson

Product Moment, the correlation of factors affecting trip

attraction and Regression analysis (stepwise method and

ANOVA). The sensitivity analysis showed, that traffic

engineering can be done to increase road capacity and to

modify land-use, especially land which is in the frontage area

in order to achieve the ideal level of service (at least C).

Another finding is that the ratio (e), which is a representation

of the characteristics of movement generation / attraction for

each land use every hour is needed. Mixed land use

development that is expected to reduce movement of land use

did not occur in this study. Mobility of traffic flow in mixed

of land use was still high, so it can be concluded that the

mixed used in this case did not work.

Beyond the boundary and design criteria of Low Crested

Breakwater (LCB), the successful of LCB application is

largely determined by the layout of the installation. The

layout includes vertical and horizontal layout. Vertical layout

related to the peak elevation position of the structure to sea

level, both to Mean Sea Level (MSL) and High Water level

(HWL). Horizontal layout regarding LCB placements related

to the optimal distance from the coast to LCB position, the

length of the structure, and the width of the gap between

LCB. These three parameters determine sediment budget.

This paper presents a summary of field experiences that

magnitude and timing information in response to changes in

water stage in stream. A device, namely the Photo Electronic

Erosion Pin (PEEP), which utilizes sunlight intensity

("photo"=light) to quantify the degree of exposure, was

adopted to provide automated, localized, quasi-continuous

measurements of mass fluvial erosion retreat lengths in

response to different magnitude of hydrologic events. Photo-

resistant PEEPs have been inserted horizontally into the bank

face (into the crest, midbank, and toe of the bank) at the

mouth (site 2) of Clear Creek, a representative stream of the

U.S. Midwest with mostly cohesive, loess-derived banks

many things including flood modelling in the river. One of

these modelling packages is HEC-RAS Hydrodynamic Model

which can be used to simulate both steady flow and unsteady

flow flow. On the other side, the development of Geographic

Information System (GIS), is now rapidly evolving for a

variety of purposes with a wider range of fields and scope,

including the preparation of river geometry data based on

Digital Elevation Model (DEM) in Triangulated Irregular

Network (TIN) format as the input of the model. The aim of

this study is to perform flood routing for determining the

river capacity and for estimating the factors that cause floods

by integrating TIN data into HEC-RAS Hydrodynamic

Model, using Lantikadigo River in Central Sulawesi,

Indonesia as a model. In this river, almost every year flooding

occurs with fluctuating intensity of inundation. Data

integration provides the effectiveness of the use of simulation

time due to input geometry data is done using import data

facility when compared manually input geometry data. The

results of the study show that the maximum water level of 1-

year return period has exceeded the river bank elevation both

on the left and on right side on the entire segment. The peak

discharge of hydrograph for 1-year return period is 55.3 m3/s

at the outlet of Lantikadigo Watershed. This means that the

average channel capacity is far below the peak discharge.

Based on simulation results it can be predicted that the cause

of flooding in Lantikadigo River is due to morphological

change of river geometry.

Big city development as the center of economic activity is a

powerful pull for society, influencing high work force from

both inside and outside of the city, causing a strong current of

urbanization. One main problem that always accompanies

urban areas development is density population. Urbanization

has caused a very rapid explosion in the city population; one

implication is the clumping work force in large Indonesian

cities. The high number of people who choose to settle in the

city increase the number of both legal and illegal settlements.

In the high-density settlement, many houses are not liveable

and irregular. In the densely populated settlements will be

found many houses that are unfit for habitation and irregular.

along the weld toe of brace-chord intersection for most

critical brace due to the joint loading. In this paper tubular

KT and K Double T (KDT) joints as an element of an

offshore jacket platform are modelled as finite element

models. The effect of multi-planarity caused by adding a

brace to the stress distribution along the weld toes is

investigated under two different loading conditions: balance

axial load and in-plane bending moment. To ensure validity

of the model, Stress Concentration Factor (SCF) of the KT-

joints model was validated by Efthymiou SCF equations. An

additional brace has been added within the validated KT-

joints models to form a multi-planar KDT joint, and the stress

distribution along the weld toes of the joints are investigated

under balance axial load and in-plane bending moments. The

results showed that under balance axial loading, maximum

stress occurred at a point of Crown 1 on the KDT-joints were

smaller than maximum stress occurred in the KT-joints as

well as the case of in-plane bending moment loading

conditions.

Model of Municipal Solid Waste Treatment Using

Mixture Design

Christia Meidiana

Brawijaya University, Indonesia


A model describing the relationship between waste treatment

method and GHGs emission is proposed in this study. Three

constituents, i.e. composting, reuse and recycle are analyzed

using extreme lattice mixture design to determine the model.

Mixture design enables identifying of optimum combination

of each constituent which produces the lowest GHG

emission. Greenhouse gas (GHG) emission as a regressand is

analyzed to how it changes as the waste amount is changed.

The result showed that there are 4 possible models. One best

model is chosen for its least standard deviation, lowest P-

value and the highest adjusted R-squared which is 5.764E-

003, less than 0.005, and 0.9908 respectively. The model

describes that lowest GHGs emission can be achieved by

maximizing plastic recycle (into flakes), limiting composting

and increasing paper, glass and metal reuse. Composting,

reuse and recycle is proportional to the GHGs emission

individually, while combination of two constituents is

inversely proportional to the GHGs emission. The lowest

GHGs may be emitted from the plant is 0.107 Gg CO2e/y

with the composition of constituents as followed: 14 %

composting, 50 % reuse, and 26 % recycle equals to 1.3 m3,

4.7 m3 and 2.1 m3 waste from each method

The flood incident of Bekasi City was caused by the flow of

run-off from the upstream Bekasi watershed and the limited

capacity of Kali Bekasi River. The amount of flow caused by

changes in land and also erosion in the upper of watershed.

The amount of erosion that occurred not only resulted in

lower water absorption capacity, but also the erosion carried

to Bekasi river and settle which ultimately reduce the flow

capacity of Kali Bekasi. Several efforts are needed to

overcome erosion problems in the upper of Bekasi watershed,

thus indirectly reducing flood problems in Bekasi City

in Universitas Jambi Mendalo

Riki Chandra Wijaya*, Rohati

Jambi University, Indonesia


The create of a hydraulic model of the water pool in the

university of Jambi Mendalo is an information system-based

performance of the existing condition of the water storage

pond at UNJA Mendalo. This information system is created

using HEC RAS software. HEC RAS is software that can be

used to create a hydraulic model of a natural channel or

artificial channel to calculate its hydraulic condition so that

the value of the storage capacity, flow rate and the inundation

area can be determined. The purpose of this study was to

create an information system from the hydraulics model of

the water pool in UNJA mendalo. With this model we can

find some related information from the hydraulic system from

the water storage pond at UNJA Mendalo. The base of this

information can be done the level of pond optimization

planning or the ability of the pool to provide water resources

for the community around the location. Furthermore, with

this information can be carried out some study of flood or the

level of pool capacity in the future so that the pool can be

used as a source of water for meeting water needs at Jambi

University. This research was carried out with the primary

and secondary data collection process. The primary data

prepared are data on the cross-section area into the pond, the

pool area data, the water level data, the length data of the

inlet into the pond, and current pool and the drainage

conditions. While the secondary data used in this study is the

average daily rainfall data from 2001 to 2010 in the district of

Muaro Jambi. Furthermore, by using these data, a direct

survey was conducted to see the conditions of land use in

every part of the area at Jambi University. Land use data will

be used as a CN (curve number) determination in

hydrological analysis. Based on the results of hydrological

analysis, it is known that the value of UNJA Mendalo water

storage capacity is around 85060 m3. By using the results in

the hydrological analysis, further analysis of the hydraulics of

the Jambi Mendalo University's channels and ponds can be

determined.

Drivability Analysis Based on the Mathematical

Model of Soil Flow Resistance

Budijanto Widjaja*, Raymond Utama, Dominico Savio

Steven Saerang

Parahyangan Catholic University, Indonesia


When a pile is driven, the soil around the pile reaches a

critical condition. This results in a failure condition for

the soil, which then moves as a viscous element. The

flow is caused by the external driving force exceeding

the static resistance of the soil. When the failure

condition is reached, the dynamic resistance of the soil

will counter the penetrating force of the pile. The

rheology model is accurate in representing the soil flow

when the critical condition is reached, because the

parameters used for the mathematical model of soil

flow resistance represent static and dynamic resistance.

The dynamic resistance is influenced by the shear

viscosity of the soil, which was determined using the

Bingham and Casson models. Discrepancy exists

between the analytical output used in the mathematical

model of soil flow resistance and the actual result.

Therefore, a correction factor is needed to calibrate the

displacement of the pile.

Study on Tropical Organic Soil Stabilization Based

on Biogrouting

Jack Widjajakusuma

University of Pelita Harapan, Indonesia


Biogrouting is a new environmental friendly

stabilization method to stabilize soft soils applying

microorganism. The microorganism produce CaCO3,

which fill voids of soil particles and bond the particles.

This work studied biogrouting of high plasticity

tropical organic soil applying Bacillus subtilis bacteria.

In order to study the effectiveness of biogrouting using

Bacillus subtilis, unconsolidated undrained triaxial and

direct shear tests were conducted on the untreated and

stabilized soils. The curing time for the stabilized soil

specimens are 7, 14 and 28 days before the tests were

conducted. In order to study the influence of the

amount of Bacillus subtilis, 6 ml and 12 ml of Bacillus

subtilis liquids were injected into the soil specimens.

The soil became stronger as the amount of subtilis used

increased. The results indicated that the longer curing

time and the higher amount of Bacillus subtilis

reflected better soil improvement in term of cohesion,

friction angle and shear stress. Injection of 6 ml and 12

ml Bacillus subtilis and after 28 days curing time

increased the effective stress cohesion values by 180%

and 270%, respectively.

The effects of solar radiation that are trapped in Earth's

atmosphere, because these events take place repeatedly,

then there is accumulation of solar radiation in the

earth's atmosphere that causes the temperature on earth

to become warmer. One of the industrial sectors that

contribute to greenhouse gas emissions in Indonesia is

the palm oil mill. Indonesia is one of the largest

producers of crude palm oil in the world. Palm oil

agribusiness invites national and global attention

related to environmental issues because they're one of

major contributor to greenhouse gas emissions. The

research will be conducted on one of the existing Palm

Oil Mill in Riau Province. The Mill that sampled is

located at Kampar Regency. Primary data was obtained

through field observation and interview with company

employee. While the secondary data is obtained from

the company's regular reports and the relevant

literature. From this research, the total emissions

generated from the palm oil mill X are 1,405.83

Using plastic waste as a construction material was one

of the techniques used to overcome the inconsistencies

associated with environmental pollution created by

indiscriminate dumping of plastic waste. It was refined

into aggregates that were utilized as a fractional

replacement for coarse aggregates in concrete mixtures.

The sole objective of this research work is to analyze

the use of plastic waste in concrete. Two types of

aggregates extracted from plastic waste namely:

Polypropylene (PP) and High-Density Polyethylene

(HDPE) were used in carrying out this study. The

percentages of PP used were 5%, 10%, 15%, while

15%, 20%, 25% were used for HDPE. Similarly, the

slump value, compressive strength, and tensile strength

were tested for 28 days and at a concrete age of 3.7.

The results obtained proved that a percentage increase

in plastic aggregate would invariably reduce the value

of slump, compressive strength, and tensile strength.

The optimum percentage of PP and HDPE used were

10% and 15% respectively. This research contributed to

providing an alternative to overcoming plastic waste.

Cold-Formed Steel (CFS) has been widely used for

residential, commercial and light industries due to

lightweight and ease to install. Development of suitable

shear connector for composite beam systems with CFS

is proposed in this research. This paper presents the

performance of the proposed shear connector using

rebar in CFS composite beam systems. A new method

is introduced to install the proposed shear in composite

beam system encased in Self-Compacting Concrete

(SCC). Three specimens are tested until failure for the

rebar of a shear connector with different configurations

with a dimension of 12 mm and 16 mm and interval

distance longitudinally 200 mm and 330 mm for the

standard push-out test. The shear capacity, ductility and

failure modes are recorded from the test specimens.

The experimental results are compared with Eurocode

4 to establish the relationship between theoretical value

and experimental value. It can be concluded that the

increased in dimension size and the reduced in intervals

longitudinal distance of rebar contributed to an increase

Effect of Temperature and Heating Time Variation

on Characteristics of Fibrous Peat Soils

Yulindasari Sutejo

University Sriwijaya of Palembang, Indonesia


Peat soil is a soil that has a large organic content and high

moisture content. During the dry season, on the island of

Sumatra, especially South Sumatra, the earth's atmospheric

temperature has increased, causing frequent cases of forest

fires on peatlands. Both those caused by humans and the sun's

heat. Increasing the atmospheric temperature of the earth and

fires on peatlands will have an impact on the characteristics

of peat soils. To find out the changes in peat soil, in this

research using temperature variations (30˚C, 50˚C, 80˚C,

100˚C, 120˚C, 150˚C) and heating time variations (6 hours,

12 hours, 24 hours, 36 hours and 48 hours). The locations for

peat soil sample: KTM Telang Mulya Sari, Dusun I Banyu

Urip, and Dusun III Banyu Urip. The optimum value of the

remaining water content (wopt) is 93.65 % of the location of

the peat soil KTM Telang Mulya Sari. These results were

obtained at a temperature of 30˚C and a heating time for 6

hours. Then for testing the unconfined compressive strength

for peat soil without heating obtained the most optimum cu

value of 0.285 kg/cm2 in the soil of Dusun I Banyu Urip. As

for the testing of unconfined compressive strength test with

heating, the highest cu value was also found in the peat soil

test specimen in Dusun III Banyu Urip which was heated

with a temperature of 150oC and a heating time of 48 hours

which was equal to 0.93 kg/cm2.

The Effect of Gypsum Plafond Waste on Shear

Strength of Soft Clay Soil

Reffanda Kurniawan Rustam

University of PGRI, Indonesia


Soil has an important role in a construction work site. One

type is soft clay soil (red soil) which has a compressibility

value and high water content that causes the carrying capacity

of the soil to be low. In this research, soil improvement was

carried out chemically by soil stabilization method using a

mixture of gypsum plafond waste with a percentage of 5 %,

10 %, 15 %, 20 %, and 25 % in a laboratory scale. Soft clay

samples used for the study were taken in the Pakjo area of

Palembang, South Sumatra Province. The use of gypsum

plafond waste as a mixture is expected to increase the shear

strength of soft clay soil. Tests carried out include testing

Direct Shear. Based on the USCS classification system, the

soil was classified as clay or CH and based on AASHTO

classification system was A-7-6. The value of wop is 22 %

(optimum moisture content) and the value of gdmax is 1.74

gr/cm³ (maximum dry weight). The maximum cohesion (c)

value is 24.20 kPa from 15 % mix of gypsum plafond waste

(WPG15) sample. For the maximum value internal friction

angle (ϕ) is16.36 °C from 5 % mix of gypsum plafond waste

(WPG5) sample. The maximum shear strength (τ) is 26.57

kPa from 5 % mix of gypsum plafond waste (WPG15)

sample.

In this study, effects of crushed stone waste from Katunun's

quarry as fine aggregate on mortar and concrete properties

will be examined. Samples with varying crushed stone waste

replacement ratio, ranging between 0% until 100%, will be

analysed at 3, 7 and 28 days curing time. Mortar sample is

using 0.5 w/c ratio, while concrete sample is using 0.45 w/c

ratio. The mixture of mortar sample is based on SNI 03-6825-

2002, whilst concrete sample is based on SNI 03-2834-2000.

The examination of concrete samples workability was

conducted based on the slump test according to SNI

1972:2008. Moreover, the compressive strength test of mortar

sample is based on SNI 03-6825-2002. In addition, the

compressive strength test of concrete sample is based on SNI

1974:2011. Regarding compressive strength of mortar

samples, the average compressive strength results of mortar

with crushed stone waste rose significantly in line with the

increase in replacement ratio. As for the workability of fresh

concrete, sample using natural river sand had better

workability compared to sample using crushed stone waste.

However, the workability of concrete with crushed stone

waste is still meet the slump value specified in the job mix

formula. In addition, it has been found out that the

combination of 75% crushed stone waste with 25% river sand

will give the highest compressive strength compared to others

combinations. Based on these findings, the utilization of

crushed stone waste from Katunun's quarry in mortar and

concrete mixture can be proposed.

compressive strength of foamed concrete with various

concrete density. This paper reports experimental

investigation on lightweight foamed concrete of 300,

600, 800 and 1000 kg/m3 densities and correlates

compressive strength and density for further strength

prediction. A total of 72 foamed concrete cubes with

various densities and water cement ratio were prepared

and tested for compressive strength at the concrete age

of 7 and 28 days. Inverted slump and flow table spread

value were obtained based on the test method stated in

ASTM C1611. The foams were produced by using

foam generator by mixing them with cement mortar

(Ordinary Portland Cement, OPC and dry sand of size

850µm). The experimental results showed the highest

compressive strength was recorded as 2 MPa for the

density of 1000kg/m3 and water cement ratio of 0.6.

The results revealed that consistency of the foamed

concrete is in the range of 0.97 to 1.03, whereas

stability index is in the range of 0.98 to 1.19 which

showed the bubbles in the foamed concrete were stable

during casting and curing process. A prediction model

with exponential equations were proposed for foamed

concrete compression strength with different water-

cement ratio and it can be preliminary used to predict

the foamed concrete strength.

paper presents the use of 10mm thick hot-rolled gusset

plate slipped between double lipped C-channel

arranged back-to-back to form the proposed composite

connection. Two specimens with and without seat angle

were tested until failure. The weakness of thin plate

behavior at the joint area was reduced by means of

angle stiffener placed at the column web. The

calculation procedure was developed due to limited

design rule in Eurocode for this connection type, and

compare with the experimental results to obtain the

relationship between these two methods. It can be

concluded that the use of seated angle has contributed

to an increase in connection capacity.

prefabrication of construction components in controlled

environment and then installed on site. It promotes faster,

neater, safer, easier and cheaper construction works in future.

Interlocking Brick (Blockwork System) is one of the IBS

which has not commonly known in Malaysia. The key

objectives of this research are to investigate the compressive

strength of long interlocking brick column with cement

mortar and SikaGrout®-215 filler under concentric and

eccentric load, in addition to study its failure mechanism and

compare the experimental result with existing design code.

Four number of 2.3-meter height column was built by using

interlocking brick with Y12 steel bar and different filler and

performed compressive strength test and the result is compare

with the existing design code which is Eurocode 2 and BS

8110. From the research, Interlocking brick column with

cement mortar filler had lower compressive strength capacity

compare to column with SikaGrout®-215 under concentric

and eccentric load. In term of failure mechanism, the column

samples were failed by sudden crushing of interlocking brick.

For column sample with grout, the percentage of difference

of BS 8110 and Eurocode 2 modified equation compare to the

experimental result is 10.20% and 12.56% respectively under

concentric load. Moreover, for column sample with mortar

infill, the percentage of difference is 67.16% for BS 8110 and

73.23% for Eurocode 2. For eccentric load, Eurocode 2 did

not provide reasonable agreement where the percentage

difference is range from 66.40% to 482.47%. The optimum

design of interlocking brick column in this study is the

column sample with SikaGrout®-215 as it has higher

compressive strength compare to Type M cement mortar.

Water is a basic human need in everyday life. However in

some areas consumable clean water is still unattainable.

There is an urgent need for water purification equipment.

Several researches on water purification devices has been

carried out with different methods. One of the methods

amongst them is using the Dielectric Barrier Discharge

Reactors. This method applies appropriate temperatures to

make it safe for use. This paper discusses about the various

methods used in water purification. The previous researchers

discussed a lot about the parameters of the ozone producing

capability. They also explained the characteristics and effects

of voltage related to voltage sources. Furthermore, the factor

of non-potable water is also used as a research material.

Based on these previous researches, the researcher reviewed

and investigated two of the types of electrodes used - The

Multi spectral capacitive sensor (MSCS) is a sensor that is

formed based on the concept of white noise impedance

spectroscopy. This concept utilizes the spectral noise

frequency approach of the frequency domain signal resulting

from the field effect on the dielectric. As a sensor, the

consistency results obtained is stable, so that it can facilitate

analysis. In this study, we tried to compare data groups,

starting with 100 data sets and 300 data sets from a total of

600 data sets for H2O and H2O mixed with NaOH materials

and H2O mixed with HCl using a new transformation,

namely Tamsir statistical transformation (TST). Furthermore,

grouping data uses the total amplitude value of each data set

obtained. We obtain the results in the form of differences

between groups of data with fluctuations in response patterns

that are close together which are shown in 2D graphics.

Hence, we can implement the data groups as a reference

pattern of fluctuations in a material

of land use. The occurrence of wind disaster can not be

predicted, when and where they occur, because the cause of

natural factors, namely differences in pressure. Disasters that

occur in Indonesia is caused by human factors, namely

changes in land use and a way of life that does not pay

attention to environmental conservation. Public preparedness

in the face of the possibility of disaster increases, when

disaster occurs they immediately evacuate themselves to a

safer place. Therefore it is necessary socialization and

understanding to the community against the possibility of

disaster, another thing to think about is preparing early

warning facilities and infrastructure. Yogyakarta is one of the

areas that must be wary of the threat of a tornado, especially

when there will be seasonal changes. The damage caused by

the wind disaster is increasing, indicating that wind speed

plays an important role in relation to the impact of damage

caused. In this research methodology of system development

that will be used is System Development Life Cycle (SDLC).

For estimation of direction and wind speed will be used

The Implementation of Permanent Magnet Material

Variations on the Reduction of Cogging Torque in

PMSG

Herlina, Rudy Setiabudy, Amien Rahardjo

Sriwijaya University, Universitas Indonesia


Permanent magnet synchronous generator is a type of electric

machine that is extensively adopted for wind turbines.

However, the operation of permanent magnets in the rotor

sets up a unique issue, particularly an enormous cogging

torque value. Cogging torque is a torque that occurs because

the interaction that takes place between the flux provided by a

permanent magnet and the slot on the stator. This torque

affects the rotor's initial movement in the generator where the

rotation of the rotor will be heavy and not smooth. Therefore,

this torque is crucial to be decreased so that indeed in small

wind speed inputs, the rotor can rotate. In this research,

variations in the handling of permanent magnets will be

analyzed, especially ALnico, NdFeB, Ceramics and SmCo

employing the anti-notch method. From the results achieved,

each type of permanent magnet influences the value of

tangential flux density which further influences the value of

cogging torque reduction. By applying the new anti-notch

method, the cogging torque value is significantly reduced

compared to the reference generator design.

Ambo Intang*, and Hendra Dwipayana

University of Tamansiswa Palembang, Indonesia *Corresponding email: [email protected]

Basically, the variation of the pump arrangement in the

piping installation is done to get the performance / flow

characteristics needed in a particular usage according to the

needs, namely the need for a head height that is higher than

the flow rate (capacity) or vice versa. Flow regulation method

with variations of valve openings (Senen 2004), which is

applied in this study with consideration of energy use

efficiency, it can be stated that the pump efficiency range of

the parallel circuit is high to get a larger flow rate than the

series circuit pump. To get the head maximum, the pump

efficiency series is smaller than the pump efficiency of the

parallel circuit, so that it does not provide an illustration that

the optimum pump work has been achieved, so that further

research needs to be carried out research with variations in

pump rotation (Mastur and Warso 2015) below or above the

standard round. But based on the purpose of this study in

terms of pump performance, to meet the needs of a high head,

the pump installation is arranged in series and vice versa if

what is needed in the pump installation system is a high flow

rate, the pump is arranged in parallel, so the results of this

study have been can meet the needs of practicum for students

of Mechanical Engineering Study Program FT. Unitas in

terms of how to get the performance of a centrifugal pump

installation.

In this paper, we study the estimated spread of fatigue crack

in the kiln shell welded under cyclic load using S-Version

FEM. By using the S-FEM technique, it makes the local mesh

which is re-meshed automatically, then it becomes easier to

make a numerical study of crack growth on the welded kiln

shell. Virtual crack closure integral method (VCCM) uses the

stress intensity factor evaluated. From the results, it was

observed that the crack depth grows faster as the number of

cycles increased. It was found that the initial crack of welded

shell propagates slowly, and beyond 8 × 105 cycles increase

quickly. In addition, the effect of stress distribution and stress

intensity factor on cracking have been evaluated and

discussed. The life of the component depends on the initial

crack depth, stress intensity factors and crack inclination

The Analysis of the Dimple Arrangement of the

Artificial Hip Joint to the Performance of

Lubrication

Hasan Basri*, Tri Ramadhoni


Artificial hip joint surgery is one of the most successful

methods used to restore the functioning of damaged hip

bones. But there are obstacles to the use of artificial hip bone,

which is the amount of friction occurring and wears. To

overcome these obstacles a surface of the artificial hip joint is

modified by adding dimples in order to minimize the contact

pressure of solid and to reduce friction and wear. The aim of

this study is to determine a better lubrication performance

with the variations of the number and pitch of dimples in

normal walking condition. Simulation results have already

passed the stage of convergence studies, and the obtained

results are such as hydrodynamic pressure, contact pressure,

and the film thickness of the lubricant with the variations of

the number and pitch dimples. The results of the CSM

method under dry condition, it shows that the addition of

surface with dimples has a positive effect to reduce the

contact pressure and indirectly reduce wear. The maximum

surface contact pressure is 54.84 MPa with dimple and 94.22

MPa without a dimple. The results of the FSI method under

lubrication condition, it was found that the variation of 7

dimples with a dimple pitch of 500 μm has the best

lubrication performance. The hydrodynamic pressure is 0.73

Pa, the contact pressure is 0.42 Pa, and the film thickness of

the lubricant is 29.59 μm. The increase of film thickness that

occurs due to hydrodynamic pressure will cause the fluid lift

force to withstand the loading of the solid structure.

This study was aims to demonstrate that bagasse as a waste

can be used for enhanced oil recovery process. Bagasse has

sufficient lignin content to be processed into sodium

lignosulfonate surfactant. The use of bagasse as raw material

of surfactant for the chemical flooding is the development in

the science of petroleum. Synthesized bagasse to

lignosulfonate was done by isolation process using sodium

hydroxide reagent and sulfonation process using sodium

bisulfite reagent. From FTIR test and NMR test, sodium

lignosulfonate (SLS) surfactant from bagasse consist of

sulfonate groups (hydrphilic groups) and benzene (lipophilic

groups). The synthesized SLS surfactant of bagasse has a

HLB value of 11.62. The presence of hydrophilic and

lipophilic components resulted in the stability of middle

phase emulsion in the range of 5% - 10% and the core flood

obtained recovery factor reaches 1.05% - 9.50%. With HLB

value of SLS surfactant from bagasse indicated that it can be

used as an injection fluid in the oil/water emulsion system,

which is indicated by the presence of a middle-phase

emulsion. Conclusion of this study indicate that the

synthesized lignosulfonate of bagasse can use an injectin

fluid in O/W emulsion and bind oil and water to form

microemulsions. The bagasse is a local raw material for

sodium lignosulfonate (SLS) surfactants which can be useful

for enhanced oil recovery.

Parting Control on Coal Seam Quality Based on

Ash Content and Total Moisture, North Musi

Rawas, South Sumatera

Jefri Putra*


In its utility, coal is measured by how much the quality values

contained inside such as ash content and total moisture. One

of the factors that affect the value of coal seam quality is the

existence of partings. Partings is an inorganic material that is

formed in coal syn-depositional. Therefore, this study aims to

identify the extent influence of the presence of the parting

layers that in comparison of the laboratory test results from

two sampling techniques. The application of the methods

used was channel sampling where the coal sample was taken

without partings and include partings. Coal seam thickness

become the object of the research was 9.01 m with the

presence of the four partings that have a thick layer of 6-8

cm. Comparative laboratory test result show ash content

include partings more bigger than without parting with a

difference of 2.7% adb. Deviation ash content the most

indicated on ply 5. Suggesting parting layer has form of

tuffaceous sandstone. Characteristic tuff is a volcanic

deposits contain a high fly ash thus increasing ash content.

While the total moisture include partings more smaller than

without partings with a difference of 0.3% ar, It was

suggested that partings just control the ash content, this is due

to the type and character of lithology parting.

The issue of earthquake with magnitude 8 SR that threatens

Jakarta has recently become a major concern due to the

chance of catastrophic. This is closely related to the existence

of a seismic gap located in Southern Java, Sunda Strait

Megathrust. The seismic gap is a segment of an active fault

known to produce a significant earthquake that shows no

earthquake activities for an unusually long time. This

situation implies that the moving crust is reserving potential

energy which going to be release and resulting massive

earthquake. The potential earthquake source located around

200 km from Jakarta which has densely populated and

frequent annual disasters such as floods and fires. Matraman

district is one of the densely populated areas in Jakarta with a

population density of 319,291 per km2. Through Geographic

information system, this research uses network analysis

methods to create an evacuation route in the event of a

disaster. This method works with a cluster system to obtain

the most effective paths in pre-determined zones. The

evacuation route resulted from this analysis used 21 zones

located in Matraman sub-district. Each zone has various

evacuation time. The fastest time range between 1 to 3

minutes and the longest about 4 to 12 minutes. This

evacuation route is also usable for SAR team and firefighter

to reach the area of disaster.

Late Neogen Deformation of Rock Successions at

Renah Gajah Mati I Region Seluma Regency in

Bengkulu

Wahidin Zuhri*, and Edy Sutriyono


Studies on tectonic deformation of the Late Tertiary sequence

during Late Neogene time has been carried out at the Renah

Gajah Mati I region using balancing and restoring techniques,

kinematic and dynamic analyses. The Late Neogene

deformation was mainly controlled by compression, which

has resulted in folding and thrusting. Hence, the rock sections

underwent shortening that varied from 1.42-1.83 km or

0.75%-0.78% with the estimated rate of deformation 0.12-

0.15 mm/year. Two types of tectonic structures developed

within the region, fault propagation folds and trishear faults.

The brittle deformation extended sequentially in the direction

of tectonic transport, resulting in a series of faults. The

generated faults constitute imbricate fans with a relatively

closely-spaced thrust system. The array of thrusts is

apparently associated with folds that strike NW-SE, implying

the geometry of fault-linked folding. The hanging wall

anticlines are generally asymmetric overturned folds,

indicating a shallow ramping fault with a high shear pattern.

In regional context, the general strike of structures within the

study area appears relatively parallel to the NW-SE trending

Barisan orogen. This feature suggests that tectonic transport

was likely at the NE- SW direction.

On January 23rd 2016 there was a landslide in the Lahat-

Lubuk Linggau railway, right at the mouth of the railway

tunnel in Lahat Regency. About 5 meters thick of soil

covered the railway, causing the railway to be stopped for

several days. Since the tunnel was built in 1928 until

landslides occur in 2016 which means it has been 88 years.

The landslide can be caused by several factors, these factors

are slope geometry, physical and mechanical characteristics

of rocks or soil, geological structure, hydrology and

hydrogeology, and external forces such as ground vibration

due to railway traffic and earthquake. The results of research

on the main causes of landslides in the mouth of the railway

tunnel include relatively steep morphological influences,

degradation of rock strength due to weathering, dip rock

structure in the direction of slope, and ground vibration due to

earthquakes. Based on field observations, the slope next to

the case study area of the landslide is also unstable.

Therefore, it is necessary to analyze the slope stability in the

area that has the potential to landslide, using a pseudo-static

slope stability analysis on the consideration of the effect of

ground vibration due to earthquakes is quite significant to

slope stability. The results of the pseudo-static slope stability

analysis is showing out that the factor of safety is around

1.22-1.16 with a seismic coefficient of 0.10-0.125 g. To

anticipate future landslide we suggest to be conducted studies

on slope stabilization methods including building retaining

walls, drainage channels and shotcrete walls.

A study of coal upgrading in briquette making

based on briquette characteritics using heated

mechanical metods

H E Handayani, Y B Ningsih and M A Arifin


Indonesia has low quality coal reserves which are quite

abundant. The low quality of coal is due to the inherent water

content that is still quite high. Therefore, an upgrading

process is needed. The upgrading process is intended to

increase the calorific value of coal. The upgrading process

can be applied to the process of coal briquettemaking.

Generally, the manufacturing of low quality coal briquettes

uses mechanical and heating methods in two different

processes. In this study, the manufacturing of the briquettes

uses the tools in a series of processes. The working principle

of this tool is based on the strength of pressure and heating

temperature. The maximum pressure is 900 psi, and the

maximum heating temperature is 1500C. One of the

important factors that determines the success of the upgrading

process is the magnitude of heating temperature. The

variations of heating temperature used are 500C, 750C,

1000C, 1250C, 1500C. The heating temperature affects the

characteristics of coal briquettes produced. The heating

temperature that produces the best quality coal briquettes is

1500C. The results of analysis of the coal briquette’s

composition are as follows: the inherent water content is

11.00%, the volatile substance level is 46.48%, the ash

content is 6.13%, the fixed carbon value is 36.39, and the

calorific value is 5.235cal / gr.
