Introduction

Perkenalkan nama saya Fairuz Athaya Naim. Saya biasa dipanggil Aya. Saya lahir di Jakarta, 3 Desember 2002. Kini saya berdomisili di Depok. Saya mahasiswa kelas Metode Numerik-05.

Summary Pertemuan 1 (26/05/2023)

Pada pertemuan pertama mata kuliah Metode Numerik, saya mempelajari terkait pengertian Metode Numerik dan pengaplikasiannya dalam menyelesaikan permasalah matematika secara numerik. Kami juga mempelajari terkait consciousness dalam hidup, yaitu kesadaran manusia untuk menerima suatu permasalahan, memprosesnya, dan mencoba untuk mencari jalan keluar dari permasalahan tersebut. Di kelas kami juga mempelajari bahwa jawaban untuk hasil dari (X²-1)/(X-1) bila X = 1 adalah 2. Saat mensubstitusi langsung nilai x = 1 maka hasilnya akan 0/0 yang artinya jawaban tersebut tidak terdefinisikan. Tetapi bila dihitung menggunakan penjabaran dan penyederhanaan akan didapat hasil 2 meskipun hasil ini tidak belum absolut karena menggunakan nilai X = mendekati 1, hasil ini dapat didefinisikan dan tidak menimbulkan keraguan. Metode Numerik digunakan untuk melakukan perhitungan dan pendekatan yang akan menghasilkan nilai yang paling mendekati benar. Jawaban tersebut tidaklah eksak karena yang eksak hanyalah Tuhan Yang Maha Esa.

Design & Optimization of Pressurized Hydrogen Storage

Designing an optimizing pressurized hydrogen storage system with a 1-liter capacity and 8-bar pressure within a budget of Rp 500,000 requires careful consideration of materials and dimensions to optimize cost. I assembled the step-by-step of designing the storage with some help by ChatGPT

Selecting the Storage Tank Material

To optimize cost, it's important to choose an affordable and suitable material for the storage tank. One cost-effective option is using aluminum, as it offers good strength-to-weight ratio and corrosion resistance. Its dimensions will be determined in subsequent steps.

Determining the Tank Dimensions

To calculate the required dimensions, we need to consider the volume and pressure requirements. The given specifications are 1-liter capacity and 8-bar pressure. The formula to calculate the required tank volume is: Volume = Pressure * (1 liter / 8 bar) = 0.125 liters/bar.

Once the radius is calculated, the height can be determined using the 2:1 ratio: height = 2 * radius

Cost Optimization

To optimize costs, consider the following factors:

a. Material Cost: Aluminum is a cost-effective material for hydrogen storage tanks. Determine the cost of the required amount of aluminum based on current market prices.

b. Manufacturing Process: Opt for a simple manufacturing process that minimizes labor and machinery costs. Welding is commonly used for aluminum tanks, but consider the costs associated with different manufacturing methods.

c. Safety Measures: Ensure the tank design meets safety standards, minimizing the need for additional costly safety features.

d. Mass Production: If feasible, consider producing tanks in larger quantities, as it can reduce costs through economies of scale.

Cost Analysis

Once I have determined the material cost and considered the manufacturing and safety factors, analyze the overall cost. If the total cost exceeds the budget of Rp 500,000, I need to revisit the design and make adjustments to the dimensions, material, or manufacturing process to reduce costs.
