[hide]Week 1
On the first week Zaki trains chatgpt about the updated version of DAI5 Applying the DAI5 Framework in Engineering: Zaki asks clarification on the DAI5 framework, a structured methodology for analyzing engineering problems. The steps—Intention, Initial Thinking, Idealization, and Instruction—were explored in depth, with specific examples illustrating how the framework can be applied to hydraulics and pneumatics. This framework was then tailored to scenarios such as designing a lifting mechanism or solving system dynamics, making it adaptable to real-world challenges.
After training the chatgpt with DAI5 methodology, Zaki brainstorms about hydraulics and pneumatics project ideas and chatgpt came up with this answer Hydraulic Systems: Lifting platforms, presses, braking systems, and steering mechanisms. Pneumatic Systems: Robotic arms, conveyor systems, clamping devices, and air-powered tools. The suggestions were structured to balance complexity and feasibility, aligning with the user’s academic goals and practical skills.
After brainstorming Zaki concluded the project he is going to do is a hydraulic car jack.
Week 2
On the second week Zaki discussed further and more detailed about the hydraulic car jack. The hydraulic car jack is aimed to be designed for a formula student car that Zaki is working on UI Racing Team. The final design is going to be manufactured and used in competition on 2025.
Here are steps given by chatgpt
Creating a hydraulic car jack tailored for a Formula Student car is a fantastic project that blends engineering design, manufacturing, and practical application. Here's an outline to guide you:
1. Define Objectives Primary Purpose: Lift a Formula Student car for maintenance or inspection. Key Specifications: Load Capacity: ~300-350 kg (typical FS car weight). Lifting Height: Sufficient to access underbody (~200-300 mm). Portability: Lightweight and compact for pit use. Ease of Operation: Minimal effort, quick actuation.
2. Key Components
Hydraulic Cylinder: Choose a single-acting cylinder with enough force to lift the car.
Frame: Use lightweight but strong materials (e.g., aluminum alloys or high-strength steel). Design for stability and minimal deflection under load.
Control Valve: Incorporate a simple release valve for controlled lowering.
Base and Wheels: Add wheels or rollers for mobility. Ensure a stable base to prevent tipping during operation.
3. Manufacturing Plan Frame Fabrication: Use welded assembly for precision. Hydraulic System: Assemble off-the-shelf components or design custom parts for optimization. Testing and Safety: Perform load testing, include safety stops, and ensure leak-proof connections.
4. Documentation Prepare CAD models, stress analysis (FEA), and detailed drawings. Document calculations and testing results for evaluation.

E. Author Declaration
1. Deep Awareness (of) I As the author, this project aligns with my commitment to innovation, practical problem-solving, and personal growth. It serves as a reflection of my role in leading the UI Racing Team, where I continuously strive to balance technical excellence with teamwork and purpose. I acknowledge the importance of staying guided by ethical practices and conscious intention throughout this process.
2. Intention of the Project Activity This project is a direct response to challenges I frequently encounter as the captain of UI Racing Team. The car jack is not just a tool; it represents a solution deeply connected to the operational efficiency and success of my team. My goal is to contribute a reliable and well-engineered device that enhances safety and convenience during competition and testing.
F. Introduction
Background and Context: As part of the Universitas Indonesia Racing Team, I frequently oversee vehicle maintenance tasks during high-pressure competition scenarios. Current lifting tools often lack the precision and compatibility required for FSAE cars, which are smaller, lighter, and require specific lifting mechanisms. The motivation for this project stems from a need to develop a tailored hydraulic jack to enhance these operations.
Initial Thinking (about the Problem): Reflecting on past experiences during competition, I identified inefficiencies in traditional lifting solutions. These included excessive weight, time delays, and limited adjustability. Research into lightweight materials and compact hydraulic systems informed the initial concept for an FSAE-specific car jack.
G. Methods & Procedures
Idealization: To conceptualize an ideal solution, assumptions were made regarding uniform load distribution and typical pit lane conditions. Material choices focused on aluminum alloys for their strength and weight benefits. Hydraulic circuit calculations considered minimal effort for maximum lift efficiency.

a. Intention
On determining the application, I was going to bring, I looked to the closest event or work I am currently working on. Since I am currently working for UI Racing Team, I chose the application of a hydraulic system for a car jack. With the ongoing problem of how difficult and heavy it is to jack the car, I wanted to apply hydraulics on the system.
b. Idealization (Initial Thinking)
I am thinking of applying this based on a scissor jack I have previously designed for the subject of Machine Visualization and Modeling on my 3rd semester. With this approach, I am utilizing what I have designed and just modifying it. This made my design useful and not go to waste since Allah doesn't like things to go to waste as it is mubazir.
c. idealization
To define parts needed by the system, first I need to define loads it has to withstand on its working basis. A Formula car is usually weighted around 250 to 300 kg. Without the driver, if the driver weighs around 60 kg, then the weight will be about 350 kg.
Safety is everything, so I am applying a safety factor of 1.5 to make sure the jack can withstand loads properly.
Car + Driver: 350 kg Safety Factor: 1.5 Requirement: 350 × 1.5 = 525 kg 350×1.5=525kg
d. Instruction Set
First, we need to define the dimensions of the hydraulic cylinder based on the load requirements.
Then we can start applying the hydraulics on the design. To ensure the strength of the system, we can do Finite Element Analysis (FEA) for stress on the system.
This project focuses on modifying a standard scissor jack into a hydraulic car jack optimized for Formula Student cars. It ensures practicality and safety through a well-defined safety factor and incorporates finite element analysis for structural validation. The design balances innovation with real-world applicability, offering a tailored solution for the team's operational needs.
