Revitalisasi Pompa Air Bertenaga Matahari Di Desa Sukaraja Lombok Tengah

Abstract

The demand for water for agricultural and domestic purposes in northern Lombok is relatively high because groundwater sources are located deep below the ground surface, requiring high-pressure pumps to deliver water. Solar energy through solar cells provides an alternative power source for operating submersible pumps to lift water from depths of up to 30 m. A solar-powered pumping unit previously installed in Sukaraja Village, Central Lombok, is currently unable to provide sufficient electrical power, resulting in continued dependence on the PLN grid. This community service activity aimed to revitalize the existing solar-powered pumping system by increasing solar cell capacity and replacing the battery to restore its optimal operation. The activities included system redesign in June–July 2025, installation of additional solar cells and battery replacement on August 22–23, 2025, followed by training on equipment operation and maintenance. The results showed that the solar-powered pumping system was successfully restored, while improving farmers’ knowledge and skills in operating and maintaining the equipment.
