Abstract

Kebutuhan air tanaman untuk fase vegetatif awal, fase vegetatif kedua, fase generatif, dan fase pematangan menunjukan nilai berturut-turut 33,77 mm/hari, 3,69 mm/hari, 3,48 mm/hari, dan 3,58 mm/hari. Neraca air menunjukan kelebihan (surplus) air terjadi pada Bulan Januari, Maret, April dan Oktober hingga Desember, sedangan kekurangan (defisit) air terjadi pada Bulan Februari, Mei hingga September. Sistem polder yang diterapkan pada lahan sawah PT. Buyung Poetra Pangan sudah memiliki semua komponen yang mendukung yaitu tanggul keliling, sistem pembawa, stasiun pompa/kolam penampung, dan badan penerima air. Kapasitas pompa menghasilkan nilai debit air sebesar 2.445,88 m^3/h. Pada saat lahan terjadi kelebihan (surplus) air, pompa air berfungsi untuk membuang air dari saluran menuju sungai. Sedangkan pada saat lahan terjadi kekurangan (defisit) air, pompa air berfungsi untuk memasukan air dari sungai menuju saluran. Kata kunci : Rawa Lebak, Kebutuhan Air Tanaman, Sistem Polder, Pompa Air.
