Floods that frequently hit the Jompo Watershed (DAS) area cause damage to irrigation networks. The magnitude of the damage certainly requires much money, while the maintenance funds are minimal and not comparable to the area of the irrigation network. This research aims to select the most appropriate priority for network rehabilitation to produce the maximum benefits. Compiling priorities uses the Analytic Hierarchy Process (AHP) method, but it contains subjectivity in the preparation of AHP. Therefore, to reduce its subjectivity, this study integrates AHP with the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) method, Weight Aggregated Sum Product Assessment (WASPAS), and Multi-Objective Optimization by Ratio Analysis (MOORA). Rehabilitation criteria assess the performance of irrigation networks by using the condition of damage to buildings (A1), availability of water (A2), area of irrigation (A3), and crop productivity (A4). The results of AHP-TOPSIS [0.1], AHP-WASPAS [0.0.8], and AHP-MOORA are effectively used in decision-making in rehabilitating irrigation networks. In addition, the results can represent the performance of irrigation networks. The priority to be rehabilitated is the Pangarengan (B3) irrigation network, with preference values of 0.72, 0.81, and 0.33.
