Abstract

AbstrakKondisi musim di Kabupaten jombang yaitu musim hujan dan kemarau membuat ketersediaan air didaerah tersebut tidak merata. Hal ini tentu diperlukan perencanaan pola tata tanam yang tepat pada jaringan irigasi gangsiran Desa Tebel Kecamatan Bareng agar terjadi kestabilan antara ketersediaan dan kebutuhan. Untuk mengetahui curah hujan rata-rata menggunakan metode rata-rata aljabar dengan data curah hujan 10 tahun yaitu 2009 - 2018, lalu untuk mengetahui evapotranspirasi dihitung menggunakan metode penman dan perhitungan debit andalan diperoleh dengan menggunakan metode FJ. Mock. Dari hasil analisis pada daerah irigasi desa Tebel diperoleh nilai debit andalan sebesar 0,017 m³/detik.Berdasarkan debit andalan tersebut diperoleh nilai NFR sebesar 88,29 mm/hari dengan perencanaan pola tata tanam padi-padi-palawija.AbstractSeasonal conditions in Jombang Regency, namely the rainy and dry seasons make the availability of water in the area uneven. This certainly requires planning the right cropping pattern on the gangsiran irrigation network in Tebel Village, Bareng District so that there is stability between availability and demand. To find out the average rainfall using the algebraic average method with rainfall data for 10 years, namely 2009 - 2018, then to find out evapotranspiration is calculated using the Penman method and the reliable discharge calculation is obtained using the FJ method. mock. From the analysis results in the irrigation area of Tebel village, the mainstay discharge value is 0.017 m³/second
