EVALUASI KETERSEDIAAN SUMBER DAYA AIR BERSIH DI KABUPATEN LOMBOK BARAT(STUDI KASUS MATA AIR LEMBAH SEMPAGE DAN RANGET)

Abstract

The availability of clean water is a primary need to support community life. This research evaluates the availability of clean water resources from the Sempage and Ranget springs in West Lombok Regency, considering the changes in land use that have occurred. Projections for clean water needs are carried out until 2034, using quantitative descriptive methods. The results show that the water discharge from the Lembah Sempage and Ranget springs has decreased significantly from 726.17 liters per second in 2023 to 328.3 liters per second in 2034. Even though it is currently still in surplus, this decrease in discharge could affect the availability of clean water in the future. front. There is a need for land conservation efforts to ensure the sustainability of these water resources
