Priority determination analysis of irrigation network maintenance in Karanganyar Regency using AHP (Analytical Hierarchy Process) method

For the sustainability of the function of the irrigation network to be maintained and improved, it is necessary to maintain and evaluate the condition of its physical infrastructure. This study analyzes the determination of irrigation network maintenance priorities in DI Bati, DI Kolokembar, and DI Soko/Jirak which are located in Karanganyar Regency. Funds distributed by the central government can be used optimally. The study used data on climatology, hydrology, and physical conditions of irrigation networks. In addition to the above data, questionnaire data on the selection of irrigation area priorities by the relevant respondents was also used. The analysis was carried out using the AHP (Analytical Hierarchy Process) method, namely by compiling a hierarchy, comparing pairs of priority values, and testing their consistency. The results of the analysis showed that the maximum water requirement for D.I Bati rice plants was 0.09 m3/sec, D.I Kolokembar 0.05 m3/sec, and D.I Soko/Jirak 0.06 m3/sec. The condition of damage to the physical infrastructure of irrigation networks is known in Bati as 71.92% moderate, Kolokembat at 56.79% heavy, and Soko/Jirat ak 75.86% moderate. Based on the analysis of criteria the most influential in determining the priority of network maintenance is Physical Infrastructure (46%), while the least influential is Plant Water Needs (11%). By (52%), D.I Kolokembar (33%), and D.I Soko/Jirak (15%.)
