Graduated from Metallurgy and Materials Engineering and Next Planning

My graduation was on Saturday February 18, 2012 in which exactly one month ago, on January 18, 2012 I was facing a thesis defense. I finally feel relieved because I've finally got a bachelor degree in engineering (SARJANA TEKNIK "ST").
On February 3, 2012,I officially became a master degree student because I'd got a new NPM, username for SIAK- NG and student identity card (KTM).
I've been getting estimate topic of my thesis for master degree. I will continue to consult with my supervisor to discuss further on the topic of my thesis. Should be made clear that the topic of my thesis is concerned with topic of my bachelor degree's thesis. I have the same supervisor, but the topic of my thesis for master degree, of course newer and more refined.
In addition, this semester I took four courses which are research methodolgy and computation, materials selection and design, advanced corrosion, and corrosion protection.
So keep reading this blog, and you'll get the latest information from me.

*Cheers*

Thesis for Bachelor Degree

Finally my thesis for bachelor degree has finished!!!!
A title for my thesis is Wet Mechanochemical Treatment on Coal-Based Activated Carbon for Hydrogen Storage.
Here is an abstract for my thesis:
Activated carbon from bituminous coal with submicrometer and nanometer size was developed for hydrogen storage materials. The purpose of this research is to increase the effectiveness of mechanochemical process on coal-based activated carbon sample used a planetary ball mill with ratio of carbon and KOH 1:1 and thermal activation process is not necessary. Activated carbon results from mechanochemical process will be made in the form of pellets with the addition of binder which is containing fructose, sucrose and oligo of by compacting. After mechanical milling process coal activated carbon obtained by the size of 414.7 nm which increased by 98.9%. Increasing the effectiveness of the hydrogen storage material can be seen from the increased capacity of adsorption of hydrogen at a temperature of-5 oC where there was an increase of ± 386.48 times and at a temperature of -25 oC there was an increase of ± 398.56 times compared with the untreated sample.

Biocomposites

In this semester I took a subject named Engineering Materials as my master degree's subject.
One of the topics in this subject is about composites. On this occasion, I will inform more details about bio composites in the aircraft industry.

Carbon Dioxide Corrosion

In this post, i will inform you about Carbon dioxide corrosion in oil and gas pipeline. i decided to choose this topic because this topic is related with my assignment in Corrosion's subject and I've just attended Corrosion seminar that discussed about corrosion in oil and gas pipeline and the main causes are due to carbon dioxide corrosion and hydrogen sulfide corrosion. but, in this post i'll only explain about carbon dioxide corrosion in oil and gas pipeline and being specific is what kind effect of acetic acid on carbon dioxide corrosion in oil and gas pipeline. so, enjoy!

Extraction of Aluminium

In my previous post, I've already inform you about High Temperature corrosion. Now, I'll inform you about extractive metallurgy. Extractive metallurgy has been called corrosion in reversed. Extractive metallurgy is the study of the extraction and purification of metals from their ores. There are several steps to extract metals from their ores. In this post, i will explain about how to extract aluminum from bauxite as its ore. (This topic is also a part of my subject)

High Temperature Corrosion

As I said,I take Corrosion Engineering as my specific major in my Master Degree Program.Now I wanna inform you about what corrosion is. Corrosion is the destructive result of chemical reaction between metal or metal alloy and its environment. There are several types of corrosion such as uniform corrosion, localized corrosion, intergranular corrosion, stress corrosion cracking, hydrogen induced cracking,erosion corossion and so on. Corrosion is also divided into aqueous corrosion and high temperature corrosion. In this time i will give you an example about high temperature corrosion.

Relaxor Ferroelectrics

Relaxor Ferroelectric is one kind of advanced ceramics. I've learned about advanced ceramics in my master's courses (subject: Engineering Materials) Here's the explanation!
