Abstract

Abstract Availability of water is one of the important factors in determining the success of farmers in their harvest, especially during the dry season. Many efforts have been made by the government to meet the needs of the community, one of which is by paying attention to development in the agricultural sector, namely in terms of providing irrigation water with a pumping system that utilizes water sources from rivers, springs, lakes, and other water sources. To find out how large the area of rice fields that can be fed by the spring, it is necessary to analyze the amount of water availability and water requirement using the F.J. Mock Method and Cropwat 8.0 software developed by FAO. The results showed, the dependable flow (P) 80% is 0.0413 m 3 /s or 41,3 lt / s with a rain catchment area of 0.493 km 2 . The highest water requirement is December dec 3 as much as 2,191 lt/ha/sec and the lowest water requirement is December dec 1. It can be concluded that the water availability is more than the water need, so the surface water in Gona Village Springs can be utilized 4 ha in the first planting season, 20 ha in the second planting season. and 5 ha in the third season.
