Rivanza Rahmantiar Maftuchan
Halo perkenalkan saya Rivanza Rahmantiar Maftuchan . Saya lahir di Jakarta , 29 April 2003 . saya memiliki riwayat bersekolah di SMPN 68 Jakarta , SMAN 55 Jakarta dan akhirnya berkuliah di Universitas Indonesia prodi Teknik Perkapalan 2021
Resume perkuliahan (26 Mei 2023)
Pada tanggal 26 Mei 2023 Pak Dai memberikan perkuliahan terkait dengan Metode Numerik yang berkaitan dengan hakikat atau fitrah manusia sebagai makhluk yang senantiasa memiliki agama . Dijelaskan oleh beliau bahwa agama dan metode numerik harus sama-sama bisa dicerna agar mendapat ketenangan . Selain itu beliau juga mengajarkan konsep agar ilmu duniawi bisa selaras dengan ilmu akhirat , karena mungkin ilmu duniawi lah yang akan mengantarkan kita pada kesadaran tentang adanya tuhan dan penciptaan alam semesta agra kita berpikir dan lebih mendekatkan kepada tuhan yang maha esa .
Untuk konsep dari pembelajaran pak Dai sendiri menggunakan konsep pembelajaran diskusi agar mahasiswa lebih aktif dalam mencari referenis , jurnal maupun situs terkait mata kuliah metode numerik yang sedang diampuh .
Tugas 1 Juni 2023 Design and Optimization of Pressurized Hydrogen Storage
Basic Design
Capacity : 1 L
Pressure : 8 bar
Cost should not exceed Rp. 500000
1. System Design: a. Storage Tank: The storage tank is a critical component of the pressurized hydrogen storage system. It must be designed to withstand high-pressure conditions, ensuring safety and durability. Various materials and designs are considered, such as Stainless steel 304.For this case i choose Stainless steel 304
b. Safety Measures: Safety is of utmost importance when dealing with pressurized hydrogen. The system design incorporates safety measures such as - pressure relief devices, -leak detection systems -structural integrity assessments to ensure safe operation and prevent accidents.
c. Compression System: A compression system is essential for filling the storage tank with hydrogen gas. The design and optimization of the compression system consider factors such as compression efficiency, energy consumption, and system reliability.
d. Control and Monitoring System: An efficient control and monitoring system is implemented to regulate the pressure inside the storage tank, monitor hydrogen levels, and ensure safe operation. Advanced sensors and control algorithms are employed to maintain optimal operating conditions.
2. Optimization Process:
a. Modeling and Simulation: A mathematical model is developed to simulate the pressurized hydrogen storage system's performance.

4. Conclusion:
The case study demonstrates the importance of design and optimization in pressurized hydrogen storage systems. By considering factors such as storage tank design, safety measures, compression systems, and control systems, the project achieves an optimized storage system that maximizes storage capacity, ensures safety, and improves overall system efficiency.
Tugas 9 Juni 2023
Pada kesempatan kali ini saya akan mendemonstrasikan cara perhitungan melalui metode koding menggunakan aplikasi phyton : Capacity : 1 L Pressure : 8 bar Biaya pembuatan : Rp. 500000 Saya menggunakan Stainless steel AISI 316 dengan konsiderasi ultimate tensille strength sebesar 520 mm
Import math
# Input volume = 1000 # dalam liter radius = 10 # dalam dm height = 3.1847133 # dalam dm
# Konversi volume dari liter ke cm^3 volume_cm3 = volume * 1000
# Konversi dari dm ke cm radius_cm = radius * 10 height_cm = height * 10
# Perhitungan luas permukaan base_area = math.pi * (radius_cm ** 2) side_area = 2 * math.pi * radius_cm * height_cm total_area = 2 * base_area + side_area
# Cetak hasil
print("Luas Permukaan: ", total_area, " cm^2")
Setelah menjalankan kode tersebut, Anda akan mendapatkan luas permukaan tabung dalam 827,952 cm^2.
Dapat diketahui pula bahwa panjang tabung = 3,184 cm dan tinggi 10 cm .
Pemilihan material saya memilih material pelat AISI 316 dengan harga tertera dibawah
Kemudian dari perhitungan
827.952 * Rp 1300 = Rp 1.076.376 ,00
