I’ve designed a high-detail Formula 1 car model in SolidWorks, focusing on aerodynamics and precision engineering. It’s a showcase of advanced CAD skills and passion for motorsport—perfect for rendering, engineering analysis, or inspiring F1 enthusiasts

Imagine a laboratory where valuable equipment is at risk because traditional locks offer no traceability. Anyone can enter, and if something goes missing, there’s no way to know who was last inside. We designed a smart solution: an IoT-based door security system using NodeMCU ESP8266 and RFID technology that reads electronic ID cards (e-KTP) as access keys. When a user taps their e-KTP & KTM (Student Card) on the RFID reader, the system verifies the unique ID, unlocks the door automatically, and logs the access in real-time to both a local database (XAMPP) and Google Spreadsheet. This system enhances security, enables instant user tracking, and leverages a national ID that everyone already owns—making it cost-effective and easy to implement. It’s not just a smart lock; it’s a secure, traceable, and scalable access control system for laboratories, offices, or dormitories. With this innovation, we move from blind access to intelligent, data-driven security.

I was part of a team that built an automated marble sorting and lifting machine with three unique mechanisms. My specific role was to architect and execute the entire electronic nervous system. I solo-designed and fabricated a custom PCB that integrated dual microcontrollers, motor drivers, Bluetooth, and robust power regulation. My parallel-circuit design guaranteed no single component failure could take down the whole system. I delivered a professional, reliable control hub that brought our team's mechanical designs to life

Rockie’s Warrior is more than a keychain—it’s a pocket-sized guardian with bold style and fearless spirit. With its striking blue helmet, shield emblem, and battle-ready stance, it adds personality and strength to your everyday essentials. Clip it on your keys, bag, or desk and carry adventure wherever you go.”

A Smart Hiking Stick that can help the visually impaired navigate and stay safe, that also provides tons of additional utility for any user.

This project aims to develop a real-time monitoring system for important water quality parameters such as temperature, turbidity (TDS & turbidity), and pH. The device utilizes sensors such as DS18B20, SEN0244, SEN0189, and pH 4052c, integrated with a WiFi-based Robotdyn Arduino Uno microcontroller, and displays data in real-time via the IoT platform Thinger.io. This system not only displays data on an LCD screen, but can also be accessed from anywhere via a cloud dashboard, and data can be downloaded at any time. Testing was conducted over 7 days and the results showed a fairly good level of accuracy and precision, as well as compliance with the BBPBAT Buleleng koi pond water quality standards. Perfect for those interested in IoT, aquaculture, agricultural automation, or electrical engineering thesis projects! ???? Jangan lupa like, follow, dan comment..
