Abstract

The aims of this study is to determine the criticality of recharge area and to assest criticality of land that occurred in the Musi hydropower catchment area. The criticality of recharge area had been analyzed by using geographic information system applications. Based on that application which covering the total catchment area of 60.369,97 ha of musi Hydropower catchment area, it has been shown that the condition of recharge area that still in good condition was 43.215,39 ha (71,58%), naturally normal condition was 6.857,31 ha (11,36), begin to critical was 2.560,28 ha (4,24%), rather critical was 5.506,40 ha (9,12%), and in critical condition was 2.230,58 ha (3, 69%). Assessment of the criticality of land was done by assessing the land cover factor, slope factor and the calculation of the erosion of Musi Hulu sub watershed land. The results of this assessment showed that the state of the land which in the state of not critical was 18.415,387 hectares (30,504%), potentially critical was 15.870,359 Ha (26,289%), rather critical was 18.073,017 hectares (29,937%), critical was 4.674,979 hectares (7,744%), and very critical was 443,170 ha (0,734%). From those analysis, it can be concluded that the recharge area and landof Musi hydropower catchment area is in the state of begin to critical.
