At the time Jilu Irrigation Region there are 16 irrigation and served the rice irrigation area of 992 ha.
In this study of irrigation performance assessment of physical and non physical condition. Where the physical assassement include the condition of building ang irrigation channels on each network, where as the non physical assessment procedures include the application of cropping pattern and techniques of water. The techniques here is the uniformity of water delivery, water delivery efficiency, and adequacy. The data used is the physical data of buildings on time Jilu Irrigation Region, the Global Plan of planning, rainfall data 2001 to 2011, discharge data on intake in the year 2001 to 2011.
