Modernization readiness analysis of Belitang irrigation system at region level using analytic hierarchy process (AHP) method

Abstract

Irrigation system management in the Belitang Irrigation System has some constraint that can be overcome by conducting irrigation modernization. Before implementing irrigation modernization, an irrigation system should be assessed to determine the level of irrigation modernization readiness stated by the readiness index of irrigation modernization (IKMI). The assessment of irrigation pillars was carried out in three regions including Belitang I, Belitang II and Belitang III. This study aimed to analyze the readiness of irrigation modernization in the Belitang Irrigation System and to determine the order of irrigation modernization development in three regions. Data was collected using 2 methods, namely walk through survey for irrigation infrastructure pillars and interviews for 4 other pillars including water availability, system management, institution and human resources. The assessment data was recapitulated and processed to obtain the IKMI. Then, decision making for the order of irrigation modernization development was conducted by using the analytic hierarchy process (AHP) method. The result of determining the IKMI was 69.05, so Belitang Irrigation System was categorized as less ready for modernization. This showed that the irrigation modernization needs to be postponed and the irrigation system is improved for 1-2 years. Furthermore, the results of the AHP analysis showed that the order of order of irrigation system development and improvement for irrigation modernization started from the Region of Belitang III, then Belitang I and Belitang II.
