Abstract

The Automatic Transfer Switch (ATS) system plays a crucial role in ensuring seamless power transfer between the main power source (PLN) and the backup generator (Diesel Generator), which requires real-time monitoring. PT Kereta Api Indonesia (Persero) utilizes diesel generators at strategic stations such as Kramasan Station to maintain operational continuity. This study aims to design and develop a monitoring system based on the Internet of Things (IoT) using the ESP8266 microcontroller connected to Firebase as a cloud storage platform, along with a mobile application for remote control and monitoring. The system is equipped with the PZEM-004T sensor to measure electrical parameters (voltage, current, power, and frequency), the HC-SR04 ultrasonic sensor to monitor fuel levels, and a DC voltage sensor to assess battery conditions. Data security is enhanced through encryption using the Advanced Encryption Standard (AES) algorithm before transmission to the cloud, and decrypted on the user application. Experimental results show that the system operates optimally, with relative error averages of 0.44% for voltage, 7.5% for current, 1.32% for power, and 4.00% for fuel level. The novelty of this research lies in the integration of an IoT-based ATS monitoring system with AES encryption for securing cloud data transmission, as well as the implementation of a multi-sensor approach in a single integrated and industry-applicable system. Therefore, the system has proven to be effective in improving the efficiency, security, and reliability of automatic diesel generator monitoring, and holds potential for broader industrial-scale implementation.
