Optimitization Assigment

The design was to create an optimized prezzuried Hydrogen Storage with a capacity of one litre, pressure eight bar, and the cost of optimization should not exceed five hundred thousand rupiah.

Based on the journal of Minghe and friends (2021)[1], there are several ways to increase the efficiency of the storage, which are :

1.) System Composition

Its a well known fact that the state of hydrogen could bring major improvement for the storage. for example the injection of liquid hidrogen into a tank using high pressure pump would actually lower the temprature while keeping the pressure high. this would actually benefitted the system as it increase the storage efficiency.

2.) Improving the tank cooling process

The tank of hydrogen storage usually a have high requirements of material. the material should be able to withstand a high range of temprature variation and pressure. the unsteady temprature of hydrogen liquid would be a huge consideration.

3.) the diameter of design

Considering the diameter of pipe during the cooling process actually would benefit the storage system itself. by changing the variable of diameter system it actually could increase the efficiency.

Now moving on, the most plausible solution to be done according to the limited budget is the second and third solution. the first solution would need a lot of resource to actually make the most perfect state of hydrogen to be keep in storage. a limtied budget of 500 thousand rupiah wouldn't be able to bring anything. The second solution could be done in small scale and based on the previous research that have been done by the the predecessor. Aluminium has a good thermal conductivty both for hot and cold temprature. adding extra layeer of insulation could be done to add a buffer zone to the system temprature. as we know that system temprature some times become a tricky variable for thermal research especially in a storaged energy study. by adding a layer of thermal insulation we could minimize the lost of energy to the system. The third solution actually the most practical solution, the researcher just need to make a proper estimation of the progress and steps. then could optimize the design by actually cutting the budet. this actually very plausible for a mere five hundred thousand rupiah budget.

Resume Pertemuan 26/5/22

Pada pertemuan pada hari jumat tanggal 26 mei 2023, saya menyadari bagaimana sebenarnya keterbatasan logika seorang individu. setiap individu berusaha untuk mencari jawaban atas permasalahan-permasalahan yang ditemui. Jawaban dari permasalahan tersebut salah satunya berupa pendekatan matematika yang dianggap manusia sebagai sebuah metode eksak atau pasti. akan tetapi seiring dengan perkembangannya manusia menyadari bahwa penyelesaian sebuah masalah secara eksak tidak selalu dapat dilakukan bahkan jika dapat dilakukan hal tersebut membutuhkan waktu yang sangat panjang dan materi yang sedikit. oleh karenanya manusia mencoba melakukan pendekatan-pendekatan dalam menyelesaikan masalah-masalah tersebut. pendekatan tersebut dilakukan secara itiriner dimana hasil yang didapatkan semakin mendekati nilai yang paling sempurna seiring dengan jumlah pengulangan yang dilakukan. ini sama hal nya dengan bagaimana konsep kepercayaan, manusia dengan segala keterbatasannya cenderung sering kali mencoba menanyakan ketuhanan sendiri melalui standar kemanusiaannya sehingga sering kali melakukan pendekatan-pendekatan.
