thank you for all of the people who work hard to made this bullen finally published and done.

In our first edion, we would like to inform you about NACE SCUI history, how and when was NACE SCUI built as the first Organizaonal of Corrosion Engineers Student Chapter. We also inform you about our alumnus, arcles that related with corosion, and many more. Last words we hope you could get much informaon about corrosion or about NACE SCUI by reading this bulen. And we are please you to give your comments and crics SCUI by reading this bulen. And we are please you to give your comments and crics about this bullen. So, happy reading Corr-Buzz, dear our beloved Members!

irst of all we would like to say Thank You to God for his blessing and merci. Thanks to all of NACE SCUI members, you guys are the inspiraon to us to made this bullen. And

Depending on whether you want to be employment (engineer) or specialist. If you want to become engineers, should joined development trainer such as Pertamina for learning overall, but if you want to be a specialist, but if you want to be a specialist, take the cerficaon and the cerficaon should focus on only one area.

Cerficaon is usually not cheap, a fresh graduate may actually rely on theory and experience when applying for a job. The theory gained in college, experience gained in the internship and praccum. internship and praccum. Moreover, if indeed the skills needed in the job you will, for sure you will be facilitated to parcipate in the cerficaon company.

A fresh graduate should know manners, should not be close themselves. Must develop so skills, adaptability to each person different.

Medco E&P Indonesia as an inspecon, and moved to OMLP. OMLP is a two-year program consisng of four six-month rotaons that allow members to build leadership and funconal skills through challenging rotaonal assignments and world-class training. Typical rotaons include one or more of the following: Manufacturing Shop Operaons Supervisor, Sourcing/Materials and Technical. Program members are also involved in GE's strategic iniaves-including GE's drive for LEAN Six Sigma.drive for LEAN Six Sigma.

I am a corrosion & integrity engineer 'in one of the oil and gas companies. Scope of my work is centered to corrosion control, so more struggling with coupon corrosion, cathodic protecon, corrosion inhibitors, and integrity issues such as vibraon, etc.

All of the course certainly useful when work, but the poron of each course is different. If in my field, 100% corrosion materials are used and supported by such other course such as failure analysis,thermodynamics,analysis,thermodynamics,material standardizaon. Science that gained aer work is how to apply all that we learned in college to the real world.

Adaptability actually is trained since our internship. there are so many we can get from the internship: network, get new knowledge, get experience to go directly to the field, get and the 'simplicity' if we want to go the 'simplicity' if we want to go back into the company's future aer graduaon. The early months work is the most severe period. We have to get used to 'the new people' every day while holding a big responsibility. responsibility.

Coang types could be limited by exposure, environmental or other ancipated condions. Determining the frequency and duraon of contact is important. Determine the type of containment structure, for example, is the containment structure being design for containment structure being design for drum or bulk storage areas. And then the physical condions of use, for what the areas will be subjected. The ambient condions is about the condions of the secondary containment, is it subjected to ultraviolet, thermal cycling or thermal expansion? And the condion of expansion? And the condion of containment structure is about the age of the containment. Is the structure new or exisng. If new, there could be areas with flaw or faulty details that need to be repaired. If the structure is exisng may have been exposed to chemical leaks or spills that could require neutralizaon, spills that could require neutralizaon, decontaminaon, or removal and replacement secon of the structure.

The lining types and selecon, there is wide array of lining systems that available for use in secondary containment structure, for example epoxies, polyester, polysulfide, etc. And the last is the surface preparaon and lining applicaon, surface and lining applicaon, surface preparaon will vary with the lining type specified. Roune inspecons of any lining systems should be performed to check. The lining system’s ability to survive these condions is directly related to the design and the construcon. construcon.

ining systems for outdoor applicaons require resistance to weathering and thermal cycling. Concrete is one of the more difficult surfaces to coat because of

In carbonaon, CO2, are from he atmosphere, reacts with Ca(CO)2 will form CaCO3 and water. The comsumpon of hydroxides ions reduces the pH of the concrete and deplete the passive layer at the surface of the steel. The penetraon of chlorides to the steel surface also breaks down the passive layer rather than aacking the steel directly. Relavely minor metal losses that do not compromise the structural integrity of metal losses that do not compromise the structural integrity of the steel can generate a volume of corrosion product that can spall and crack the surrounding concrete. This accelerates the penetraon of aggressive species. This is key factor in the corrosion of bridge decks. So, by the mid1970s, the deterioraon of concrete bridge structure in cold climates was caused by corrosion of the reinforcing steel in the concrete, which, in turn, was induced by the intrusion of chlorides from deicing salts into the concrete.

In areas of strategic importance such as highway belts of most modern cies, the total cost of repairs is greatly amplified by adding the indirect cost of traffic disrupons. A number of fundamental measures can be taken to address the problem of reinforcing steel corrosion; for example, creang a barrier between the concrete and/or the rebar and the exisng environment or applying cathodic protecon to the rebar environment or applying cathodic protecon to the rebar structure. For new stuctures, much progress will be made toward effecve corrosion control as life-cycle cosng strategies are adopted, as opposed to awarding contracts solely on the

basis of lowest inial capital cost outlays. Using alternave methods of reinforcement, such as fiber-reinforced polymer composites, corrosion-resistant stainless steel rebar, epoxy-coated rebar to reduce the exposed steel surface is the best thing to decrease the cost.

Another is that the extremely high pH of the cement content (commonly pH bigger than 13 for new concrete) passivates the steel surface against corrosion acvity. The main causes of corrosion of steel in concrete are chloride aack and carbonaon. These two mechanisms are unusual in penetrang the concrete without significantly damaging it structurally. These chemical species pass through the pores in the concrete and deplete the alkanity that passivates the steel surfaces. But, deterioraon process resulng from chemical aack on concrete by acids and aggressive ions, such as sulfates, destroy the integrity of the concrete before the steel is affected. integrity of the concrete before the steel is affected.

teel-reinforced concrete is a very importan material of construcon. One reason for the success of the combinaon is the similarity of the thermal expansion properes of carbon steel and concrete.

ne of the board of Professional division, Danang and another member of NACE SC-UI, Aziz and Fashana get invitaon to present a presentaon their paper in a conference in

Kyoto, Japan. We thank not only because of the rain water rain water provides a source of water and irrigate the fields but because of the rain water has led us to go to Kyoto, Japan.

Then why rain ? We realize that rain water nowadays not just contain H2O or Cl-, but also contain mixture of other weird things. Someday we were astonished to see some experiment about rain water in different parts of the world that indicate such ions like experiment about rain water in different parts of the world that indicate such ions like nitrate , sulfate , fluoride , etc. We heard in our lesson those ions cause ping corrosion. And then we want to know how big the effect of rain on corrosion in our neighborhood. The queson is what our environment like? then we want to put on a great mother of stainless steel that is 304 but dillema appears when a lot of data already discussed corrosion of stainless steel in SS304, we finally tried using the children of mothers stainless steel that in fact is the 316 series 300 with the addion of Mo the most widely used . Finally we make a simulaon of rainfall and its influence on literature , but it turns used . Finally we make a simulaon of rainfall and its influence on literature , but it turns out aer we study literature because of things they will be less cool rainwater and SS316 no variable that changed , for that we ulize the exisng ions in water as the rain all variables to compare the effect of ion the nature of the exisng corrosion . Aer to see if it can be made to the research we began to ask Prof. Johny, Mr Munir, Mr Yudha, Mr Diles, and Mr Akbar on a cool method for research, and abstract. As we connue to make our meline for the study for approximately one month and a half with a 40-day detail to learn literature and preparing the samples remainder. And finally we were invited to learn literature and preparing the samples remainder. And finally we were invited to present in that conference.
