Analysis of Gegesic Divider Irrigation Door Opening 5 for Water Demand Efficiency

Water resources management is critical in supporting sustainable agricultural development and ensuring food security. Efficient water use in irrigation systems is required to optimize crop growth and production and minimize water wastage. This study aims to analyze the opening of irrigation sluice gates at the Gegesik 5 distribution gate to improve water demand efficiency. The research methodology included field observation, data collection, and calculations to determine the optimal sluice gate opening based on water availability and crop water requirements. Factors such as rainfall, evapotranspiration, crop water requirements, and irrigation system efficiency were also considered. The results showed that the non-secondary door height was 5 cm, and the tertiary door opening was 10 cm. The highest percentage of water demand efficiency in the channel is in Bundermire 1 Ki Channel at 99.74%, which indicates that the use of water in the primary channel is quite efficient, the lowest percentage of water demand efficiency is in Gegesik Ki 1 Channel at 76.47%, in other channels, the efficiency level is obtained in Bundermire 2 Ki at 93.13%, in Bundermire 2 Ka at 77 26%, Bundermire 1 Ka at 87, 69%, Gegesik Ki 2 by 78.20% and Gegesik 5 channel by 94.90% so as to identify the actual water demand for various activities and apply water-saving technologies and methods by applying the sluice gate opening strategy, then this research has implications for the management of water resources in the study area can be optimized to contribute to sustainable agricultural practices and food security.
