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.

The Quadcopter Y1101 is a 3D SolidWorks–modeled, high-aerodynamic-resistance racing drone designed for precision, speed, and stability. This project merges simulation-driven design with hands-on fabrication, using 6-inch NACA-M18 propeller blades to maximize lift efficiency and maintain stability at high flight velocities. However, the blade design is fully parametric and customizable, meaning the propeller geometry can be modified or redesigned based on the research methodology being pursued. This allows engineers and researchers to explore performance variations across different airfoil profiles, pitch angles, and chord lengths, enabling targeted optimization for speed, stability, and flight precision in both racing and research applications. The Y1101 was created as a 3D-printable prototype platform for testing aerodynamic performance and control algorithms, bridging the gap between simulation-based design and real-world racing drone prototyping.
