Resume Pertemuan 1 - 26/05/2023
Pada pertemuan pertama, hari jumat 26 mei 2023. kami dijelaskan mengenai sebuah konsep atau teori yang digagas oleh pak DAI. yaitu adalah "i'm my conciesness". maksudnya adalah, kita sebagai manusia dituntut untuk bisa sadar akan suatu realitas yang kita jalanin. sebagai contoh, kita masuk kedalam kelas dan mengikuti suatu pembelajaran. dimana selama kelas tersebut kita dipaparkan mengenai berbagai macam materi yang diterangi oleh dosen. Lalu, setelah kelas selesai kita harus dapat tersadar akan materi yang diberikan tersebut. seperti, apakah kita dapat mengambil sangkut paut terhadap sebuah permasalahan pada dunia nyata, atau mungkin mengambil suatu relevansi terhadap hal yang realistis.
Pada pertemuan tersebut, pak DAI juga memaparkan keterkaitan ilmu matematika terhadap conciusness atau kesadaran kita terhadap realitas. Pada contoh tersebut, pak DAI mengatakan bahwa ilmu matematika sebenernya bukan suatu ilmu yang eksak atau memberikan hasil yang absolut pada setiap jawaban atau hasil perhitungannya. melainkan sebuah pendekatan yang dilakukan demi menemukan sebuah jawaban dari suatu permasalahan. Dengan begitu, dibutuhkan lah suatu metodr numerik demi dapat melakukan suatu pendekatan yang optimal pada suatu permasalahan yang kita temui di dunia ini ataupun pada kehidupan sehari hari.
Case Study of pressurized Hydrogen Storage Optimization Project
according to thetask that has been explaned in the class, our job is to design & do optimization of pressurized hydrogen storage. the specification of the storage is, it should be having 1 litre capacity. then, the pressure inside the storage should be around 8 bars. and the, the cost of the storage shouldnt be more expensive than Rp.500.000. the first step i do on how i do all of those assignment is i try to looking for reference so that i can have a vision of how i do the assignment. so, as one of my strategy and tactis i use chatGPT as one of my tools to assist me on this assignment. ChatGPT give me almost all of the step on how designing and optimization to this hydrogen storage.
Material Selection: on desgingin, oe of the fiest step that we'll do is Choosing the materials for our product. we choose materials that are lightweight, durable, and can handle high-pressure conditions. Common materials used for hydrogen storage include carbon fiber composites, high-strength alloys, and specially designed polymers. The ideal material for a high pressure cylinder has a very high tensile strength, a low density, and does not react with hydrogen or allow hydrogen to diffuse into it. Most pressure storage to date have used austenitic stainless steel (e.g. AISI 316 and 304 and AISI 316L and 304L), Cu, or Al alloys, which are largely immune to hydrogen effects at ambient temperature
Tank Design: on our effort to Optimize the tank design to maximize the storage capacity while ensuring safety and cost-effectiveness. Consider factors such as shape, volume, and thickness of the tank walls. Cylindrical or spherical shapes are often used for pressurized gas storage. lets take our number, to design 1 litres capacity atleast we need to have 200mm height and radios of 40mm of cylindrical storage.
Safety Measures: Incorporate safety features such as pressure relief valves and burst discs to prevent over-pressurization. It is crucial to ensure that the tank can withstand extreme conditions without failure. that's why we have to designing this storage with almost approaching precise equation so that we can sure that this storage is safe.
Efficiency Considerations: Look for ways to improve the system's efficiency by minimizing heat transfer and hydrogen loss. Implement insulation materials to reduce heat transfer, which can help maintain the hydrogen's temperature and pressure. this activity, is concluded on the optimization stuff because here we will try to minimize the loss that happen on the storage because of the heat transfer.
Manufacturing Techniques: Choose cost-effective manufacturing techniques such as filament winding, which involves wrapping carbon fiber around a mold, or bladder molding, where a bladder is inflated within a mold to create the tank shape. in this case, we will choose Filament winding, its is a fabrication technique mainly used for manufacturing open like cylinders or closed end structures such as pressure vessels or tanks. This process involves winding filaments under tension over a rotating mandrel.
Cost Optimization: the effort that we do to keep the cost of the storage being under 500,000 rupiah is that we will consider factors such as material costs, manufacturing techniques, and economies of scale. Bulk purchasing of materials, optimizing manufacturing processes, and minimizing waste can help reduce costs.
