Abstract

The policy of food security has been formulated and established by Indonesian government in order to increase food production one of several programs proposed include land expansion for rice farming through extensification agricultural system. Gunung Mas regency with total areas of 1,084,012 hectares, geographiclly, located at upland areas with elevation range 100 to 500 meters above sea level and it consists primarily of hillocky plain and mountainous including specific river stream system covered this region. The need of land use planning and policy was then urgently required since the region has opportunity to be developed especially for agriculture. The objective of this study was to determine appropriate landuse based on the potential of water resource through delineation areas for rice farming according to it suitability within watershed areas. In the view of the scarcity of data, basic information that was used include landform data devired from DEM. The technology of GIS and remote sensing was spatially used to generate slope classes, river system, and resulting data from land evaluation process. The result of spatial analysis showed that land utilization for rice farming development was allocated in the southern part within watershed areas of Kahayan, Rungan, and Manuhing river with total area of 200.254 Ha or 86.83% of total developed areas for rice farming. While in the north, land allocation with total area of 30.373 Ha (13.17%) where located at watershed of Kayahan river was established for the future use. The water management within watershed areas can then be formulated based on the availability of water resource to to meet water supply through irrigation system
