Hello All!

My name is Reyhan Fachriansyah, you can call me fahri. This is my page that contains the progress of my ongoing assigned project for Numerical Method course in my fourth semester. My future goal is to establish several high-tech manufacturing company revolving around robotics, sensors, and renewable energy. I hope by undertaking this course, i will bring my self closer to my goal by expanding my knowledge and conciousness

23 May 2023

This day is the first day of our course, lectured by Pak Dr. Ahmad Indra Siswantara or commonly called as "pak Dai". In this day we were given knowledge about how conciousness highly important to our daily life espescially affecting Numerical Methodology. Pak Dai also lectured us about Cara Cerdas Ingat Tuhan.

On today's session, Mr. Dai assigned us to discuss together about our main project of Numerical Method with our friend Patrick Samperuru as the discussion moderator as the head of class's replacement. Each of the attendants will given several chance of public-explanation in front of the class in order to complete our project, which entails designing a functional hydrogen tank that is optimized within the constraints of pressure constraints at 8 bar, 1 liter capacity, and a maximum budget of IDR 500,000, all participants are asked to contribute their thoughts in the form of opinions and personal viewpoints. There were two session on todays dicussion, which is material discussion and constraint discussion.

The discussion was then continued by one of our friend Patrick Samperuru in the first discussion for applicable materials, Patrick then listed a number of possible materials that can be used as the hydrogen tank based on the different hydrogen tank types such as type I, (all metal), type II, (metal with a carbon fiber wrap), type III, (composite with metal lining), and type IV, (composite with non-metal lining). But for this project, he reckon that the most probable type of hydrogen tank would be the type I or II since the production would be easier, and also theoritically be able to withold 8 bar of pressure, thus the end production price will be more affordable for our capped cost of IDR 500,000. Patrick the stated the details of several possible material that can be applied as hydrogen tank, this inlcudes AISI 316, AISI 304, AISI 316L, AISI 304L. Cu, or Al alloys are commonly used as the main material for hydrogen tanks since it is largely immune to hydrogen effects at ambient temperatures

Hydrogen Tank Design and Optimization Project

This design and optimization project is assigned by our lecturer Pak Dr. Ahmad Indra Siswantara as an individual project/task as a learning method to use Numerical Method as a tool for real-life application problems. The project consist of designing a hydrogen tank with some constraints: consider being the gas pressurized at 8 bars, a required volume of 1 liter, and a maximum budget of 500,000 IDR to make one. Hydrogen gas has a high level of danger espescially when pressurized to a high pressure by reason of the likelihood of explosion. Thus, it is crucial for engineers to design and optimize a safe hydrogen tanks for several type of real life practices.
