This study aims to analyze the actual irrigation water losses in the Jimat Irrigation Area, identify the factors causing irrigation water losses, and determine effective strategies to reduce water losses in the area. One of the important irrigation areas in this region is the Jimat Irrigation Area, which supplies water to 110 hectares of agricultural land. However, the effectiveness of water distribution is often hampered by significant water losses. The research methods used are descriptive evaluative and quantitative descriptive analysis. The descriptive evaluative method describes a study that evaluates the actual conditions of the study object. Meanwhile, the quantitative descriptive analysis method aims to accurately describe the characteristics of the study object. Based on the analysis and calculations, the Jimat Irrigation Area requires an actual irrigation water supply of 0.812 m³/second to serve its four tertiary canals, with the highest allocation going to Tertiary Channel 2 (0.465 m³/second) and the lowest to Tertiary Channel 4 (0.084 m³/second). However, only 54% of the initial discharge of the primary canal (1.702 m³/second at the Upstream Intake) actually reaches the agricultural land. A total of 46% of the water (0.686 m³/second) is lost along the primary network, with seepage accounting for 99.94% of the water loss, particularly in critical sections such as Primary Channel V, which lost 59% of its discharge. Meanwhile, the contribution of evaporation is minimal (0.06%) due to the limited water surface area and low daily evaporation rate (2.76 mm/day).

Conclusion

The study concludes that the Jimat Irrigation Area requires a continuous water supply of 0.812 m³/second, but significant water losses, primarily due to seepage (99.These losses are particularly pronounced in Primary Channel V, where 59% of the discharge is lost.Therefore, interventions such as impermeable linings, crack repairs, and improved institutional control are crucial to restore reliable water distribution and enhance agricultural productivity.

Future Research

Further research should investigate the long-term effectiveness of different impermeable lining materials in reducing seepage rates under varying soil conditions and climatic factors within the Jimat Irrigation Area. Additionally, a comprehensive socio-economic study is needed to assess farmers willingness to adopt and maintain water-saving technologies, and to design effective incentive programs that promote sustainable irrigation practices. Finally, exploring the integration of real-time monitoring systems, such as IoT-based sensors, with predictive modeling techniques could enable proactive water management strategies, optimizing water allocation based on forecasted demand and minimizing losses through automated control of irrigation infrastructure, ultimately enhancing the resilience of the agricultural sector in Wonosobo Regency to future water scarcity challenges.
