IMPLEMENTASI PLTS MINI UNTUK OPTIMALISASI PROSES PENGERINGAN HASIL LAUT DI DAERAH PUNAGA TAKALAR

Abstract

The implementation of a mini solar power plant (PLTS) was carried out to enhance the efficiency and sustainability of the marine product drying process in Punaga Village, Takalar. This community service program was conducted through an implementation-based approach that included system design, equipment installation, community training, and realtime field monitoring. The system consists of five 30 W solar panels arranged in a tree-like structure, 35 Ah and 65 Ah batteries, a 30 A solar charge controller (SCC), a 1000 W inverter, and an artificial heating unit composed of four 20 W lamps and two 15 W heaters. During the daytime, drying is performed using direct solar radiation, while at night the process continues using stored battery energy to operate the heaters. Environmental parameters such as solar intensity, temperature, humidity, and wind speed were monitored using BH1750, DHT11, and anemometer sensors, with data visualized through the MIT App Inventor platform and stored in Firebase Realtime Database. Field observations recorded the highest solar intensity of 1064.75 Ir/m² at 14:00. At night, the system delivered an inverter output of 217 V with a power of 117.1 W and an efficiency of 78.90%, which gradually decreased to 97.66 W. This community service activity demonstrates that the mini PLTS system can significantly optimize the marine product drying process while promoting renewable-energy utilization and sustainable practices for coastal communities.
