ANALYSIS OF OPERATION PERFORMANCE AND MAINTENANCE OF IRRIGATION NETWORK IN NORTH MOROWALI DISTRICT

Tambayoli Irrigation Area (Provincial Authority) located in North Morowali Regency has an area of 1,210 hectares, functional area 904 hectares, the realization of planting area I (MT. I) = 622 Ha, Planting Period II (MT. II) = 634 Ha. The Mamosalato Irrigation Area (Regency Authority) is also located in North Morowali Regency which has an area of 374 Ha, 152 Ha Functional Area, the realization of planting area I (MT. I) = 90 Ha, Planting Period II (MT. II) = 123 Ha. The irrigation area in these 2 (two) locations utilizes river water flow as a source of water, but there are several Irrigation Areas which are irrigation areas that can be classified as technical irrigation networks because they have permanent tapping structures and structures for those who are able to regulate and measure water flow. In irrigated areas, irrigation network operations and maintenance are rarely carried out. Therefore, it is necessary to evaluate the operation performance and maintenance of irrigation networks to determine the extent of the irrigation system's performance. The purpose of this study is to determine the performance of the authority of the Province D.I irrigation OP. Tambayoli and D.I. Mamosalato. Methods of data analysis were carried out by means of surveys and direct interviews in the field. The results showed that based on the overall index assessment the performance of the D.I. irrigation system. Tambayoli is 71.31%, which means that the performance is good (70% - 79%) while the performance of the irrigation system is D.I. Mamosalato is 44.55%, which means poor performance and needs attention (
