Abstract

There were problems to meet water demand in 431-hectare Jatikulon irrigation area in Mojokerto District from Brantas river. The purpose of this study was to obtain maximum irrigation yield in limited field under the dependable discharge constraint by Linear Programming. The variables are area of paddy, corn, and sugarcane. The constraints are dependable discharge and available irrigation area. The objective is to maximize irrigation yields. The optimization analysis reveals that the largest dependable discharge is 712 l/sec. The highest water demand for paddy, corn, and sugarcane are 2.487, 1.180, and 1.282 l/sec/ha respectively. The designed crop plants are 62 ha paddy, 369ha corn, and 0 sugarcane in season I; 0 paddy, 356ha corn and 0 sugarcane in season II; and 0 paddies, 194ha corn, and 0 sugarcane in season III. The maximum profit in season I, II, and III are Rp.6,730,554,448, Rp 5,118,677,651, and Rp.2,790,580,427 respectively.
