Kadir S. 2015. Land cover to control the level of criticality Satui watershed in Province of South Kalimantan. Pros Sem Nas Masy Biodiv Indon 1: 1190-1196. Land cover is the main factor determining the degree of criticality of land, so the land cover change should correspond with the capability through which degraded land can be controlled. This study aimed to determine the condition of land cover vegetation and critical level in the watershed land in DASatui South Kalimantan province. The benefits are expected to be a reference that determines the direction of lowering the critical level of vulnerability of land to control flooding and improve the productivity of the land for public welfare. Determination of the critical level of soil, vegetation land cover conditions and direction control are executed through a spatial approach to the condition of land cover by utilizing Geographic information systems. The study results showed that: (i) Land critical criteria (critical and very critical) covers an area of 34435.67 hectares in the existing land cover condition of 49703.37 ha (32%); (ii) land critical criteria (critical and very critical) covers an area of 1536.82 ha on the condition of forest vegetation cover alternatively landing into an area of 66975.57 ha (44%), while the open land, shrubs and reduced mining area are 17782.99 ha (12%).
