<![CDATA[Budget constraints require local governments to select the most valuable irrigation investments rather than simply follow a list of rehabilitation needs. This study develops a two-stage decision framework for the 38 irrigation schemes under the authority of South Sulawesi Province. The first stage screens investment feasibility using capital budgeting (NPV, IRR, BCR) and life cycle cost analysis (LCCA) at discount rates of 12% and 15%. The second stage ranks the feasible schemes with the Best-Worst Method (BWM), based on the judgments of 30 experts, and the MARCOS method across six criteria. Twenty-eight schemes are feasible under both scenarios, requiring IDR 326.80 billion (45.7% of total needs) while generating 80.9% of the present value of benefits (aggregate BCR 3.12); the remaining 10 schemes absorb 54.3% of investment with a BCR of 0.62. The technical criterion carries the highest weight (0.235), followed by environmental (0.182), economic (0.170), strategic/policy (0.169), service (0.147), and social (0.097). MARCOS yields high-priority (10 schemes; IDR 120.29 billion), medium-priority (12), and low-priority (6) groups whose order differs from both physical damage and project economic performance. Feasibility screening contributes most to budget effectiveness, while multi-criteria ranking sets the funding sequence and supports differentiated financing sources.]]>
