Resume Kuliah Pertemuan 26/05/2023

Pada pertemuan ini, dijelaskan tentang penjelasan metode numerik dan penerapannya yang berhubungan dengan kehidupan. Lalu diberikan soal yaitu berapakah nilai X^2-1/X-1 jika X=1, penyelesaian untuk soal ini ada dua cara. Cara pertama jika langsung memasukin nilai x=1 kedalam persamaan tersebut maka akan didapatkan nilai 0/0 (tidak terdefinisi), pembagian 0/0 didalam matematika itu menimbulkan ambiguitas karena hasilnya tidak eksak dan tidak mempunyai nilai numerik yang tepat, mungkin bisa menggunakan bahasa pemrograman untuk mendapatkan nilai yang mendekati 0 tapi nilai tersebut tetap tidak eksak. Cara kedua dengan menjabarkan persamaannya tersebut menjadi (x+1)(x-1)/(x-1) maka akan didapatkan nilai 2. Namun kedua jawaban ini tetaplah tidak eksak karena yang eksak di dunia ini hanyalah Tuhan yang Maha Esa.

Design & Optimization of Pressurized Hydrogen Storage

Designing and optimizing a pressurized hydrogen storage system with a 1-liter capacity and a pressure level of 8 bar while keeping the cost below Rp 500,000 requires careful consideration of various factors. On this occasion, I am using ChatGPT to answer the question. Here's a high-level approach you can follow:

Tank Selection

Choose a suitable tank material and design that can withstand the required pressure and store 1 liter of hydrogen. Common materials for hydrogen storage tanks include carbon fiber composites and certain types of steel.

Tank Sizing

Determine the optimal tank size based on the desired capacity of 1 liter and pressure level of 8 bar. Consider factors such as the hydrogen's density, temperature effects, and safety margins.

Safety Measures

Ensure that the storage system incorporates safety features to prevent leakage, rupture, and other hazards. This may include pressure relief valves, burst discs, and proper sealing mechanisms.

Material Cost Optimization

Explore various materials and manufacturing techniques to reduce the cost of the storage system while maintaining safety and performance requirements. This may involve analyzing different suppliers, considering alternative materials, or optimizing the manufacturing process.

Manufacturing Process

Optimize the production process to minimize costs. This could involve techniques such as automated manufacturing, bulk purchasing of components, or leveraging economies of scale.

System Integration

Consider the overall integration of the storage system within the larger hydrogen infrastructure. This includes connections to hydrogen production and distribution systems, as well as any necessary safety interlocks or controls.

Cost Analysis

Conduct a comprehensive cost analysis, factoring in material costs, manufacturing costs, quality control, safety measures, and any other associated expenses. Ensure that the total cost remains below Rp 500,000.

Performance Optimization

Assess the overall performance of the storage system, including factors such as efficiency, weight, and size. Look for opportunities to optimize the design to enhance performance while keeping costs within budget.

It's important to note that the cost of hydrogen storage systems can vary significantly depending on factors such as local market conditions, manufacturing capabilities, and specific design requirements. The provided budget constraint might be challenging to achieve, so additional research and cost analysis would be necessary to identify specific solutions that meet your requirements.
