RANCANGAN POLA TANAM DI DAERAH IRIGASI (STUDI KASUS DI MOLEK MENGGUNAKAN PROGRAM SOLVER)
ABSTRACT: The Molek irrigated
area is watered from Blobo dam with discharge range 6811.106 1/s to 7563.470
1/s that watering farming area of 3974 ha, with the labor of 33219 HP/periode
and the tractor power of 48619 HP/period.
The water availability, labor, and land area are limited resources,
therefore it is the reason why the optimum management is needed to gain maximum
profit. Solver program that is set in
extention microsoft exel can be used for optimation. The aim of this research is to find out
optimalization cropping pattern and maximum profit of the the limited water
availability, labor, and land area.The study showed that Molek irrigated had
optimum cropping pattern as followed: (1) Paddy¬-paddy-paddy cropping pattern
was 3400 ha, paddy-paddy-palawija was 305 ha, suger cane was 49 ha, (2) The
maximun profit of the three patterns was Rp. 115.196.679.500, (3) The water
availability and labor in Molek irrigated was sufficient for the pattern of
paddy-paddy-paddy of 3400 ha.
