Introduction
Assalamualaikum warahmatullahi wabarakatu. Perkenalkan nama saya ichram fauzan biasa dipanggil ichram. Lahir di jakarta pada tanggal 20 Januari 2004 dan sekarang berdomisili di cibubur dengan NPM 2106731024 dari jurusan Teknik Perkapalan UI 2021
Salam Kenal Semuanya...
Perkuliahan 26/05/23
Pada pertemuan kelas Metode Numerik yang diajar oleh Pak DAI, pertama-tama dia berkenalan dengan mahasiswanya dengan tanya jawab mengenai metode numerik dan content yang di kirim di WAG. Lalu kita diberikan sebuah tugas untuk merancang sebuah tabung hidrogen berisi 1 liter dengan tekanan 8 bar dan budget dari pembuatan tabung tersebut harus dibawah 500.000, tujuan dari tugas ini untuk mengefesienkan bahan bakar pada kendaraan, karena jika hidrogen di campur dengan bahan bakar dapat meningkatkan efesiensi sebanyak 30%. Lalu beliau memberikan nasehat kepada mahasiswanya untuk memanfaatkan potensi yang dimiliki sebaik mungkin dan menekankan kepada mahasiswanya untuk memanfaatkan waktu sebaik mungkin untuk belajar dengan mandiri tidak hanya pada saat perkuliahan dan juga berinteraksi dengan dosen. Lalu Pak DAI juga menjelaskan bahwa metode numerik pada jaman ini dapat memudahkan kita jika menggunakannya dengan baik, contohnya adalah ChatGPT
Design & Optimization of Pressurized Hydrogen Storage
Tujuan : Merancang dan Mengoptimalisasi Tabung Penyimpanan Hidrogen
Spesifikasi :
- Kapasitas : 1 Liter
- Tekanan : 8 Bar
Biaya Tidak Lebih dari Rp.500k
Saat saya mengetahui bahwa perlu medesain projek tabung hidrogen ini, saya sadar bahwa saya perlu bantuan dalam mencari informasi tentang bahan dan prosedur untuk merancang dan mengoptimalisasi tabung penyimpanan hidrogen. Alat bantu yang saya gunakan untuk mencari informasi adalah ChatGPT. Berikut adalah respon yang diberikan oleh ChatGPT
-> Merancang dan mengoptimalkan sistem penyimpanan hidrogen bertekanan membutuhkan beberapa langkah penting. Berikut adalah penjelasan untuk membuat dan mengoptimalkan tabung penyimpanan hidrogen :
1. Tank Material
Material: Choose a tank material that is lightweight, durable, and compatible with hydrogen storage. Considering the budget constraint, a high-density polyethylene (HDPE) tank can be a cost-effective option
2. Tank Design
Select a tank type suitable for pressurized hydrogen storage. In this case, a Type IV tank, which consists of a composite overwrapped pressure vessel (COPV), can be a suitable choice due to its lightweight nature.
3. Manufacturing Process
The process of manufacturing a hydrogen tank involves shaping the base material into a tank shape, as with the extrusion method, where HDPE in resin form is heated and pressed through an extruder. After extrusion the tube will be cut to specifications, make sure the tube is cut with precision
4. Safety Measures
To prevent leakage, do a good seal on both ends of the HDPE tube. The sealing method may include heating and compacting the tube ends to seal them thermally or using other methods according to the HDPE material
5. Testing and Certification
After the hydrogen tank has been manufactured, it is important to testing to ensure safety and performance. Quality testing may include hydrostatic pressure testing, leak testing, visual testing and other relevant tests to verify cylinder quality. Ensure the tube meets applicable safety standards and obtain required certification
-> Untuk mengoptimalan tabung penyimpanan hidrogen dapat melakukan tahap berikut :
- Determine Storage Requirements - Evaluate Different Storage Methods - Optimize Cylinder Size

# Material properties and safety factor for HDPE yield_strength = 30 # MPa (Megapascal) safety_factor = 2 # Safety factor for design # Conversion factors mpa_to_bar = 10 # 1 MPa = 10 bar # Convert pressure to MPa pressure_mpa = pressure / mpa_to_bar # Calculate the radius radius = math.sqrt((volume * pressure_mpa) / (math.pi * yield_strength * safety_factor)) # Calculate the height height = 2 * radius # Convert radius and height to millimeters radius_mm = radius * 1000 height_mm = height * 1000 return height_mm, radius_mm
- Specify the volume and pressure
volume = 1 # Liter pressure = 8 # bar
- Calculate optimized dimensions
optimized_height, optimized_radius = calculate_optimized_dimensions(volume, pressure)
- Print the result
print(f"The optimized height and diameter of the HDPE hydrogen storage vessel for {volume} liter capacity and {pressure} bar pressure are approximately {optimized_height:.2f} mm and {optimized_radius:.2f} mm, respectively.")
