The rapid growth of the Internet of Things (IoT) has encouraged the development of smart systems to enhance security and user convenience in public facilities. Locker and device charging services in futsal facilities are still commonly managed using conventional systems that lack monitoring and access control. This study aims to design, implement, and evaluate an IoT-based smart locker and charging station system for a futsal facility in Kediri Regency, Indonesia. A Research and Development (R&D) approach was employed, including system design, prototype implementation, and performance testing. The proposed system uses an ESP32 microcontroller as the main controller, an HC-05 Bluetooth module for local communication with an Android application, an ESP32-CAM module for visual monitoring, solenoid locks for electronic access control, and Firebase as the cloud backend. Experimental results show an average image capture delay of 1.75 s, solenoid lock response times in the millisecond range, an average image transmission delay to Firebase of 4.74 s, and stable Bluetooth communication within indoor operational distances. Functional testing confirms that all application features and the charging station operate as intended. These results indicate that the proposed system is feasible as a secure and integrated smart locker solution for futsal facilities.
