Abstract

Sumba Island is a semi-arid climate with an average annual rainfall of 800 mm. Low rainfall has an impact on the low potential of water resources needed for agriculture. This study was conducted to compare existing irrigation water supply techniques and water saving supply techniques. The water supply applied in the study area is a conventional technique, while the new technique that will be compared is SRI (System of Rice Intensification). The SRI technique is expected to save irrigation water and thereby increase the planted area. The available discharge data is used to calculate the irrigation water balance. The conventional method results show that the area of rice fields that can be irrigated for the first planting season to third planting season were 57.5 hectares, 32 hectares, and 19 hectares, respectively. The area of rice fields that can be irrigated by the SRI method for the first and second planting season is 85.5 hectares, and third planting season is 54.9 hectares. Compared with the conventional method, applying the SRI method can increase the planted area by 155.8% in the first and second planting season.
