UTILIZATION OF GIS TECHNOLOGY FOR PRIVATE FOREST DEVELOPMENT IN KEDUANG SUB WATERSHED, WONOGIRI DISTRICT

Private forest development has a strategic objective, namely to supply logs as raw materials for the timber industry. The research was conducted in the Keduang Sub-watershed, Wonogiri District. The research objective was to determine suitable tree species and locations for Private forestdevelopment using a Geographical Information System (GIS). The parameters used were production age, soil texture, elevation, and type of production (wood, Multi-Purpose Tree Species / MPTS). Soil types in the Keduang sub-watershed are Litosol (Entisols), Latosol (Inceptisols), and Mediterranean (Ultisols). To determine suitable tree species and locations for Private forestdevelopment, an overlay (with a GIS tool) is carried out between the soil texture map, elevation map, and land cover/use map. Based on the land cover/use map, the area of land suitable for Private forest development is 4,011.95 ha consisting of scrubs (215.51 ha), fields/moor (3,639.84 ha), rainfed fields (114.68 ha), and pasture (41.92 ha). The results of the contour map analysis show that most of the study area has an altitude of
