Abstract
Abstrak Sumberdaya air penting untuk pemenuhan kebutuhan semua makhluk hidup termasuk manusia. DAS Bodri menyediakan suplai air permukaan melalui sungai-sungai yang ada dalam DAS, yang dapat dimanfaatkan oleh penduduk sekitar. Seiring berjalannya waktu, DAS Bodri mengalami perubahan penggunaan lahan yang menyebabkan terjadinya peningkatan kebutuhan air dan terjadi ketidakseimbangan antara kebutuhan dan ketersediaan air permukaan. Tujuan dari penelitian ini, yaitu mengetahui keseimbangan antara kebutuhan air di masa yang akan datang dengan ketersediaan air permukaan di DAS Bodri tahun 2040. Perhitungan keseimbangan antara kebutuhan dan ketersediaan air permukaan dilakukan dengan membandingkan antara kebutuhan air total dan ketersediaan air permukaan. Parameter kebutuhan air total terdiri dari kebutuhan air domestik, fasilitas kesehatan, fasilitas pendidikan, fasilitas peribadatan, perkantoran, industri, pertokoan dan pasar, warung makan, peternakan, irigasi, dan tambak. Kebutuhan air di tahun mendatang diketahui melalui proyeksi secara eksponensial dan tetap dari data jumlah dalam perhitungan parameter. Kebutuhan air untuk aktivitas domestik dan nondomestik diestimasikan mencapai 2,44 miliar m3 pada tahun 2040. Hasil analisis neraca air menunjukkan bahwa status neraca air DAS Bodri tahun 2010-2019 mengalami defisiensi. Hal tersebut menunjukkan bahwa potensi sumberdaya air permukaan masih belum mencukupi untuk pemenuhan kebutuhan air di DAS Bodri hingga tahun 2040. Abstract Water resources play an important role in meeting the needs of all living things, including humans. The Bodri watershed provides surface water supply through rivers on the watershed, which the local residents can use and utilize. Over time, the Bodri watershed underwent landuse change, which led to an increase in water demand, resulting in an imbalance between water demand and surface water availability. Calculation of the balance between demand and surface water availability is done by comparing the total water demand and the surface water availability. This study aims to determine the balance between future water demand and surface water availability in the Bodri watershed in 2040. The parameters used to determine total water demand consist of water needs of the following sectors; domestic, health facilities, educational facilities, religious facilities, offices, industry, shops and markets, food stalls, livestock, irrigation, and ponds. In the coming year, water demand is known through projections exponentially and permanently from the amount of data in the calculation of parameters. Water demand for domestic and non-domestic activities is estimated to reach 2.44 billion m3 in 2040. The water balance analysis results show that the status of the Bodri watershed water balance in 2010-2019 is deficient. The potential for surface water resources is still insufficient to meet the water needs in the Bodri watershed until 2040.
