Abstract

Irrigation pump system is one that is designed in such a type of irrigation possible for local irrigation water source has a lower elevation than the agricultural area to be drained, in other words the water raised and fed to irrigated areas with the help of a pump. The purpose of this paper as an effort to overcome the crisis of water shortages for agriculture in Nagari Desa Baru Kecamatan Ranah Batahan Kabupaten Pasaman Barat. The amount of evapotranspiration can be calculated using the modified penman method. Mainstay discharge calculated using the method FJ. MOCK and obtained the minimum water availability is 1,291 m3 / sec and a maximum of 6,737 m3 / sec. To determine the water company needed cropping pattern was rice-crops-rice, used five alternative time from planting to the maximum water demand is 0.180 m3 / sec. Pump capacity obtained with the 8.2 m high manometric is 6200 liters / min and the amount of pump power 4 units with each pump 11 kilowatt or 14.74 HP, a pump operating at peak demand is for 10.452 hours. Planned primary channel with trapezoidal cross-section width of the base line (b) is 0.54 m and the width on the wet channel cross-section (a) is 1.60 m, height wet channel cross section (h) is 0.54 m.
