Resume 26/05/2023

Pada pertemuan pertama, saya mempelajari bahwa metode nemuerik adalah metode yang digunakan untuk menyelesaikan suatu permasalahan matematika yang kompleks melalui pendekatan secara numerikal. Matematika adalah ilmu pasti, akan tetapi kemarin saya menyadari bahkan di matematika pun tidak semua jawaban absolut atau eksak (pasti). Contoh dari soal (x-1)^2/(x-1) dengan x = 1. Apabila langsung disubstitusikan maka hasilnya ada 0/0 atau tidak terdefinisikan, sedangkan apabila dijabarkan melalui pendekatan secara limit, maka hasilnya adalah 2. Akan tetapi 2 juga bukan merupakan jawaban eksak karena pendekatan secara limit menjadikan x mendekati 1, bukan x = 1 (absolut). Oleh karena itu, di dunia ini yang abosolut hanyalah Tuhan Yang Maha Esa. Pada pertemuan kemarin, saya juga mempelajari tentang “counciousness”. Dalam menyelesaikann suatu permasalahan, kita harus “councious” mengenai permasalahan tersebut dan mencari solusi untuk menyelesaikannya. Selain itu, kami juga mendapatkan tugas untuk mendesain 1 liter tabung hidrogen dengan tekanan 8 bar dan biaya maksimal Rp. 500.000,00

Design & Optimization of Pressurized Hydrogen Storage

In the first week of progress, we focused on the design and optimization of a pressurized hydrogen storage system with a 1-liter capacity and 8-bar pressure, all within a budget of Rp 500.000,-. This undertaking required careful consideration of various factors including materials, dimensions, and cost optimization. Here is an overview of the design and optimization approach employed:

Material Selection: In order to meet the budgetary constraints, a cost-effective option for the storage system material is high-density polyethylene (HDPE). This material offers good chemical resistance while being affordable.

Container Design: To achieve practicality and common usage, a cylindrical shape was chosen for the container design, given that it is well-suited for pressurized storage. The dimensions of the container were determined based on the desired volume of 1 liter and pressure of 8 bar.

Wall Thickness: The necessary wall thickness was calculated using Barlow's formula: t = (P * D) / (2 * S), where P represents the pressure (8 bar), D denotes the diameter of the container, and S signifies the allowable stress for HDPE. It is important to ensure that the calculated wall thickness falls within manufacturing capabilities and budget constraints.

Optimization Strategies: Various optimization strategies were implemented to achieve the desired outcomes:

Material Cost: Different HDPE suppliers were compared to identify the most cost-effective option for material procurement.

Manufacturing Process: Consideration was given to the extrusion or injection molding processes for fabricating the HDPE container. These processes are known to be cost-effective, particularly for cylindrical shapes.

Size Optimization: The dimensions of the container were fine-tuned to minimize material usage and manufacturing costs while still meeting the required volume and pressure specifications. This involved adjustments to the container's diameter and height.

Safety Considerations: Incorporating safety features into the design was of paramount importance. This entailed the inclusion of pressure relief devices and adherence to safety standards and regulations governing hydrogen storage.

By following this design and optimization approach, a pressurized hydrogen storage system with a 1-liter capacity and 8-bar pressure could be realized within the specified budget constraints.
