Perencanaan irigasi sistem pompa di nagari desa baru kecamatan ranah batahan kabupaten pasaman barat
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.
