Abstract

Generator sets (generators) are backup power sources that have an important role in maintaining operational and service continuity at the Surabaya Aviation Polytechnic when there is a disruption of electricity supply from PLN. The reliability and availability of generators are the main factors that determine the sustainability of educational activities, practicums, and campus facility operations. This study aims to analyze the reliability and availability of the Cummins Silent 500 KVA Generator Set engine based on operational and maintenance data during the January-December 2024 period. The study used a descriptive quantitative approach by utilizing data on operating hours, scheduled maintenance times, repair times due to damage, and number of component failures. The analysis was carried out using the indicators of Specified Operating Time (SOT), Actual Operating Time (AOT), Mean Time Between Failures (MTBF), Reliability, and Availability. The results showed that the average reliability level of Generator Set 1 was 98.90%, while Generator Set 2 was 99.15%. The largest decrease in reliability occurred in Generator Set 1 in June with a value of 94.47%, which was caused by damage to several components thus increasing repair time. Meanwhile, the average availability rate of Generator Set 1 and Generator Set 2 reached 95.10% and 95.24%, respectively, indicating that both units still have a good level of operational readiness. The results of this study can be the basis for the preparation of preventive maintenance strategies and equipment performance evaluations to improve the reliability and continuity of electrical power supply at the Surabaya Aviation Polytechnic.

Abstract

Small-scale Microhydro power plants (100 Watt) require a real-time and accurate power monitoring system to improve efficiency and maintenance. This research aims to develop an Internet of Things (IoT)-based electrical power analysis system by utilizing a Web Service based on the CodeIgniter Framework to process and display data online. The system consists of sensor modules (voltage and current) using ZMPT101B and ACS712, an ESP32 microcontroller for data transmission, and a CodeIgniter backend that provides a RESTful API for data storage and processing. Power (P), voltage (V), current (I), and energy (kWh) data are displayed on a web dashboard with graphic visualization using Chart.js. The research method uses a Research and Development (R&D) approach with stages of needs analysis, system design, implementation, and testing. The test results show that the system is able to monitor power with 95% accuracy compared to digital multimeter measurements, and has a data transmission latency of <2 seconds. This solution can be applied to small-scale Microhydro power plants for IoT-based monitoring with low cost and high scalability.
