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.

Tugas besar Pada kesempatan kali ini saya akan mendemonstrasikan cara perhitungan dari data : Capacity : 1 L Pressure : 8 bar Cost should not exceed Rp. 500000 Saya menggunakan Stainless steel 304 dengan kebutuhan ultimate tensille strength : 505 mpa dan tensille yield strength sebesar 515 mpa . Kita akan mengetahui dimensi yang ada pada tabung ini mencakup panjang , lebar , luas permukaan , dan volume dari tabung hydrogen storage ini .

import math

# Parameter desain
volume = 1  # Volume hydrogen storage dalam liter
tekanan = 8  # Tekanan hydrogen storage dalam bar
biaya = 500000  # Biaya hydrogen storage dalam Rupiah

# Properti material
yield_strength = 205  # Yield strength dalam MPa
ultimate_tensile = 515  # Ultimate tensile strength dalam MPa

# Konversi satuan
volume_m3 = volume / 1000  # Mengubah volume menjadi m^3
tekanan_pa = tekanan * 100000  # Mengubah tekanan menjadi Pa

# Menghitung panjang tabung
 panjang_tabung = (4 * volume_m3 * ultimate_tensile) / (math.pi * tekanan_pa * yield_strength)

# Menghitung lebar tabung
  lebar_tabung = math.sqrt((4 * volume_m3) / (math.pi * panjang_tabung))

# Menghitung tinggi tabung
  tinggi_tabung = 2 * lebar_tabung

# Menghitung luas permukaan tabung
  luas_permukaan = 2 * math.pi * lebar_tabung * (lebar_tabung + tinggi_tabung)

# Menghitung volume tabung
 volume_tabung = math.pi * (lebar_tabung**2) * tinggi_tabung

# Menghitung radius tabung
  radius_tabung = lebar_tabung / 2

 # Menampilkan hasil perhitungan
 print('Panjang Tabung:', panjang_tabung, 'm')
 print('Lebar Tabung:', lebar_tabung, 'm')
 print('Tinggi Tabung:', tinggi_tabung, 'm')
 print('Luas Permukaan:', luas_permukaan, 'm^2')
 print('Volume Tabung:', volume_tabung, 'm^3')
 print('Radius Tabung:', radius_tabung, 'm')

Kemudian hasil yang didapat dari tabung tersebut adalah : 
Panjang Tabung: 3.998282716698835e-09 m
Lebar Tabung: 564.310731726544 m
Tinggi Tabung: 1128.621463453088 m
Luas Permukaan: 6002577.031324962 m^2
Volume Tabung: 1129106212.2639785 m^3
Radius Tabung: 282.155365863272 m
