The area of irrigation in this study is 6.689 Ha. Factors for determine irrigation water requierments include land preparation, consumptive use, oercilation and seepage, change of water layer and effective rainfall. Calculation of irrigation water requirements is carried out in two ways, namely calculation by manual method (KP-01) and calculation using CROPWAT version 8.0 The need for irrigation water starts from the beginning of November using the rice-paddy cropping pattern. From manual calculations (KP-01 Concept), the maximum irrigation water requirement is 0,97 ltr/sec/ha while CROPWAT is 1.134 ltr/sec/ha. For the minimum in the manual (KP-01) 0.07 ltr/sec/ha while CROPWAT is 0.0069 ltr/sec/ha. The maximum requirement (KP-01) occurs in November while CROPWAT occurs in the 3rd period in November and the 1st period in May, for the minimum (KP-01) occurs in the 1st period in Februari while CROPWAT occurs in the 3rd period in June.
