PENILAIAN KINERJA DAN PENANGANAN SISTEM IRIGASI PADA DAERAH IRIGASI UBUD BALI

Abstract

Ubud irrigation area is one of the irrigation areas, located in the Oos Watershed, Gianyar Regency, Bali. The successful performance of the irrigation system is highly dependent on the management of the irrigation system. It is reflected in the ability to support the system operation providing sufficient water for a conducive implementation of the crop pattern in the service area. It is very important to evaluate the performance of the irrigation system to monitor the condition and performance of all aspects of the irrigation system. The purpose of this study is to obtain a performance index assessment of the primary and secondary networks of the Ubud irrigation. The priority for handling irrigation networks is determined using the decision-making method using the Analytic Hierarchy Process (AHP) Method. Calculation of cost for operation and maintenance (AKNOP) is also implemented. The performance index assessment in the Ubud Irrigation Area obtained is 72.22% consisting of 32.36% physical infrastructure; planting productivity 11.31%; supporting facilities 6.47%; personnel organization 10.75%; documentation 3.40%; and associations of farmers using water 7.93%. Priority determination of irrigation assessment using the AHP method returns the aspects of the physical infrastructure at the first priority rank. The sub aspect of structure on the channel under the physical infrastructure aspect is selected to be handled due to the highest percentage of damage of 32.15%. The AKNOP value of structures on the channel in the Ubud Irrigation Area is Rp. 391,078,799.00. Implementation of maintenance activities consists of routine and periodic maintenance, which are light maintenance and repairs.
