A Motorcycle Security System Based on Rfid Technology Using the Indonesian Electronic Identity Card (E-KTP) as an Ignition Key

Motorcycle theft is one of the most frequent criminal acts in Indonesia and is closely related to the limitations of conventional vehicle security systems in preventing unauthorized access. This study proposes the design and implementation of a motorcycle security system based on Radio Frequency Identification (RFID) technology that utilizes the Indonesian electronic identity card (e‑KTP) as an ignition key. The research employs a Research and Development (R&D) approach with the ADDIE model—Analysis, Design, Development, Implementation, and Evaluation—to ensure a systematic and iterative development process. The proposed system consists of an RFID RC522 module, Arduino Uno microcontroller, relay‑based ignition switching, and an LM2596 step‑down DC–DC power regulator. Experimental testing shows a 100% authentication success rate for registered e‑KTP cards, with an effective reading distance of up to 2 cm. Non‑metallic enclosure materials have negligible impact on reading performance, whereas metallic materials significantly attenuate the RFID signal. These results indicate that the proposed design is effective and feasible as a low‑cost embedded security enhancement that integrates the national ID infrastructure into motorcycle access control
