Abstract

Meskipun jumlah ketersediaan air mencukupi, namun bila dalam pendistribusian air tidak diatur dengan baik, maka hal ini dapat menyebabkan tidak dapat mencukupi seluruh areal yang direncanakan. Hal ini tentu dapat menyebabkan terjadinya penurunan efisiensi karena lemahnya pengelolaan jaringan irigasi, yang dapat meningkatkan kehilangan air karena rembesan, perkolasi, dan pendistribusian air yang tidak tepat. Kinerja suatu saluran irigasi ditentukan oleh efisiensi distribusi air, keseragaman, dan kecukupan air. Penelitian ini bermaksud untuk mengevaluasi jaringan saluran irigasi Sekunder Bendung Gebong dan menghitung ketersediaan dan kebutuhan air.

Abstract

Ketersediaan air untuk irigasi merupakan salah satu faktor utama keberhasilan kinerja suatu daerah irigasi. Meskipun jumlah ketersediaan air mencukupi, namun bila distribusi air tidak terjaga maka dapat menyebabkan air tidak dapat mencukupi seluruh areal yang direncanakan. Penurunan efisiensi dapat terjadi karena lemahnya pengelolaan jaringan irigasi yang dapat meningkatkan kehilangan air karena rembesan, perkolasi, dan pendistribusian air yang tidak tepat. Penelitian ini bermaksud untuk menganalisis debit dan efisiensi pada saluarn primer Nyeredep Aik Bual Kecamatan Kopang. Adapun tujuan dari penelitian ini adalah untuk mengetahui kondisi dan keadaan jaringan irigasi Embung Aik Bual terkait efisiensi. Data sekunder yang digunakan dalam penelitian ini adalah data pengukuran langsung pada saluran Inflow-outflow untuk setiap pengamatan. Hal ini dapat dilakukan dengan mengukur debit inflow pada pangkal saluran dan debit outflow pada ujung saluran dengan menggunakan pelampung dan persamaan Manning. Debit air pada saluran primer irigasi Nyeredep Aik Bual sebesar = 0,538 m3/det, kehilanga air sebesar = 0,078 m3/det, rembesan tidak ada karena kondisi saluran saat dilakukan penelitian sangat baik dengan konstruksi pasangan batu kali, evaporasi sebesar = 3,63483 * 10-08 m3/dt ini hamper tidak ada sangat kecil sekali. Efisiensi pada saluran primer irigasi Nyeredep sebesar = 87,34 %, Ini menunjukkan bahwa 87,34 % dari debit air yang masuk ke saluran primer irigasi Nyeredep dapat sampai ke ujung saluran, sedangkan 12,66 % lainnya hilang akibat evaporasi dan lainnya, artinya saluran primer irigasi Nyeredep pada saat dilakuakn penelitian masih sangan baik, dalam pengambilan data lapangan peneliti mengukur sepanjang 20 meter sebelum saluran tersier.

Abstract

Saluran irigasi memegang peran penting dalam menjamin kontinuitas suplai air bagi pertanian, terutama di wilayah tropis seperti Kabupaten Lombok Tengah. Penelitian ini bertujuan untuk menganalisis ketersediaan debit air pada saluran primer irigasi Pelambik dan mengevaluasi kecukupannya terhadap kebutuhan air pertanian. Metode yang digunakan adalah pendekatan hidrolika melalui rumus Manning dan Chezy, serta analisis kehilangan air akibat perkolasi dan evaporasi. Data diperoleh dari survei lapangan dan instansi teknis. Hasil penelitian menunjukkan bahwa debit yang tersedia sebesar 1,196 m³/det menghasilkan suplai air harian sebesar 51.667,2 m³. Kehilangan air akibat perkolasi dan evaporasi sebesar 564,56 m³/hari atau sekitar 1,1% dari total debit harian. Hal ini menunjukkan bahwa saluran primer Pelambik masih cukup efisien dalam mengalirkan air, namun perlu dilakukan pemeliharaan untuk mengurangi potensi kerugian air di masa mendatang.

Abstract

The purpose of this study was to analyze the drainage channel dimensions in relation to rainfall discharge in Ampenan District. The types of research that can be used in dimensional analysis of drainage channels include descriptive methods and quantitative approaches. The results show that the dimensions of the Ampenan District drainage channel, with a cross-sectional area of ​​2.99 m2 and a flow velocity of 18,609 m3/s, result in the existing or control discharge (QT) of 55,640 m3/s. Meanwhile, rainfall results in a design discharge (QT) of 1,8018 m3/s, so the control discharge is greater than the design discharge (QT < QR), indicating that the channel dimensions are still adequate and can accommodate rainfall.
