      Abstract
      Danau SDGs memiliki potensi dan dapat dimanfaatkan sebagai sumber air irigasi. Pemanfaatan air Danau dilakukan dengan konstruksi bangunan pengambilan (intake) sesuai dengan satuan kebutuhan air irigasi. Tujuan dari penelitian ini adalah mengetahui kapasitas tampungan dan kisaran volume Danau, menentukan kapasitas intake Danau untuk memenuhi kebutuhan air irigasi, dan merencanakan desain pintu intake. Metode yang digunakan yaitu pengukuran langsung dengan Echo Sounder untuk memperoleh kedalaman, analisis debit dengan neraca air FJ Mock, dan analisis kurva lengkung kapasitas Danau, dan penentuan dimensi pintu air sesuai dengan Kriteria Perencanaan Irigasi-09 tentang spesifikasi teknis pintu air. Volume kapasitas tampungan optimal Danau SDGs adalah ±1218.07 m3 dengan luas ±6000 m2 berada pada elevasi ±163.5 mdpl. Kapasitas intake yang diperoleh untuk debit pengambilan yaitu 0.002 samapi 0.011 m3/det dengan luas lahan yang dapat dipenuhi kebutuhan irigasi adalah 6.36 ha sampai 20.58 ha. Dimensi pintu intake yang digunakan yaitu tinggi 80 cm dan lebar 60 cm dengan pola operasi bukaan pintu adalah 2.7 cm sampai 16.83 cm untuk memenuhi kebutuhan irigasi yang optimal.
       
      SDGs Lake has the potential and can be utilized as a source of irrigation water. The utilization of the lake water is carried out through the construction of an intake structure according to the irrigation water requirement unit. The objectives of this research are to determine the storage capacity and volume range of the reservoir, to determine the intake capacity of the reservoir to meet the irrigation water needs, and to plan the design of the intake gate. The methods used include direct measurement with an Echo Sounder to obtain the depth, discharge analysis using the FJ Mock water balance, and analysis of the reservoir capacity curve, as well as determining the dimensions of the water gate according to planning irrigation criteria (09) about gate technical specification. The optimal storage capacity volume of the SDGs Reservoir is approximately 1218.07 m3 with an area of approximately 6000 m2 at an elevation of approximately 163.5 m above sea level. The obtained intake capacity for withdrawal discharge ranges from 0.002 to 0.011 m3/sec, with a land area that can meet the irrigation needs ranging from 6.36 ha to 20.58 ha. The dimensions of the intake gate used are a height of 80 cm and a width of 60 cm, with a gate opening operation pattern ranging from 2.7 cm to 16.83 cm to meet the optimal irrigation requirements.
