The document discusses a prototype of a home security system utilizing RFID technology with e-KTP (electronic identity cards) and the Internet of Things (IoT). The implemented system uses a nodemcu v3 ESP8266 microcontroller to read RFID tags, monitor activity via a PIR sensor, and manage access through a connected Android application. Performance evaluation indicates that the system can read e-KTPs at a distance of 4 cm and demonstrates good quality of service metrics for throughput and delay.
