Analisis ekonomi teknik pemanfaatan operasi embung juruk Kabupaten Blora

Abstract

Blora Regency is known as a drought-prone area due to its karst landscape, which results in limited water availability, especially for agricultural purposes. To mitigate this issue, the Juruk Reservoir has been planned as a rainwater storage facility to support irrigation during the dry season. This study evaluates the economic feasibility of the Juruk Reservoir project using four financial assessment methods: Net Present Value (NPV), Internal Rate of Return (IRR), Benefit-Cost Ratio (BCR), and Payback Period (PP). The findings indicate that the project is economically viable. The NPV values are Rp 42,451,774.96 before construction and Rp 60,872,499.84 after construction, signifying positive financial benefits. The IRR for the post-construction scenario is 32.84%, exceeding the Minimum Attractive Rate of Return (MARR) of 6%, while the IRR for the pre-construction scenario is undefined due to an absence of cash inflows. The BCR for the post-construction scenario is 2.10, indicating that benefits significantly outweigh costs. Additionally, the PP is approximately 2.5 years, much shorter than the planned 20-year service life of the reservoir.With proper maintenance, the reservoir's functionality can extend beyond 20 years, ensuring continuous water availability for agriculture and mitigating drought impacts. The study concludes that the Juruk Reservoir is an economically feasible investment, offering significant long-term benefits for sustainable water resource management in Blora and other similar regions.
