Greetings!
My name is Patrick Ray Samperuru, I am an undergraduate mechanical engineering student from batch 2021 at Universitas Indonesia. Currently, my passion and interests revolve around manufacturing engineering ranging from automation to supply chain management, as I seek to one day revolutionize the manufacturing industry in Indonesia. In the Numerical Method course, I hope to learn many new things that would help open my consciousness towards the real world!
Class Recaps

The first class of Numerical Method with our lecturer, Pak Dr. Ahmad Indra Siswantara, involved the introduction to the concept of his base teaching regarding consciousness and his theory of "I'm my consciousness". According to Pak DAI, our consciousness plays a pivotal role in the way we grasp things in life as demonstrated by how we are able to comprehend numerical mathematical problems of 1/0 which equals infinity and (x^2-1)/(x-1). He explains how our consciousness is a gift from God that separates us from other living beings in which Pak DAI introduces the concept of CCIT or Cara Cerdas Ingat Tuhan. Here, we are invited to discuss the importance of consciousness and how it relates to using numerical method. Finally, Pak DAI assigned us our project for the remainder of the semester.
Hydrogen Tank Design and Optimization Project
The individual project for the Numerical Method course with Pak Dr. Ahmad Indra Siswantara is the design and optimization of a pressurized hydrogen tank with constraints we need to consider being the gas pressurized at 8 bars, a required volume of 1 liter, and a maximum budget of 500,000 IDR. In this case study, we are asked to create the hydrogen tank design while also being within the set parameters. The details of our design is free to our choice, ranging from the material selection to the dimensions of the diameter as well as length of the tank.
Hydrogen tanks, also known as hydrogen cartridges or cylinders, refer to containers that are used for storing hydrogen may it be in a gaseous or liquid state. The chemical element of hydrogen (H) is a non-metal that has an atomic number of 1, which is gas at room temperature making it the lightest element. Hydrogen is highly utilized in various industries used in fuel cells for generating power, refining petroleum, as well as producing fertilizer. Despite its many uses, hydrogen is a highly combustible energy carrier which can diffuse with certain materials, meaning there are risks that come with its storage. Several important aspects that need to be considered when creating a storage for hydrogen as following:
- Fatigue Resistance: As the tank will be filled and refilled after usage often, it will go through a cycling of load which in time will deteriorate the condition of the tank. Additionally, hydrogen can embrittle certain materials made of metal causing further wear in the container. With this, it is crucial that the hydrogen tank has a high fatigue resistance to withstand wear over time.
- Leak Tightness: Leaks in the tank can cause serious damage due to the nature of the hydrogen. As a fuel, this element is highly flammable making it prone to causing fires when exposed to potential sparks/ignition. Given hydrogen tanks are stored in a cluster, a leakage can result in explosions endangering operations as well as human life. Thus, it is important for tanks to always retain its hydrogen and only be released under controlled conditions.
- Adequate Weight: The weight of hydrogen tanks while not light still need to be considered for the application of transportation. The storage of hydrogen tanks are usually in accumulation meaning in quantities more than one. Given this condition, it is important to consider the weight of the tanks to ensure that more tanks can be transported in one time, thus cutting costs and creating more profit.
- Effective Construction: The design of hydrogen tanks need to be optimized in a sense that there is a optimized amount of room for the tank to store the hydrogen element. In an effective construction, the tank has enough thickness to prevent leakage and have a high resistance to fatigue while also maximizing the area for the hydrogen to be stored. This would lower the cost for manufacturing as well as maintenance as the material usage is optimal while being able to bring the most amount of hydrogen.
