Abstract

Watershed Tabunio is one of the watershed in Tanah Laut District which has an important role to support the environmental aspects and socio-economic aspects, it is caused by the upstream part of the watershed there are different types of land use can increase the rate of erosion, the flow surface , Also on the middle and downstream utilized by the Tanah Laut for agriculture, plantation and fisheries. This study aims to determine the level of erosion, which is useful as a reference for determining the direction of land use for watershed restoration efforts Tabunio. This research method using a regional approach ecological watershed analysis process and presentation done spatially through Geographic Information Systems. The results showed that: a) Amount highest erosion 219,08ton / ha / yr on land unit (LU) 3B (mining land use with a gradient of 3-8%), while the lowest amount of erosion 11,44ton / ha / yr on UL 8 (use of secondary dry forest with slopes 25-40%); b) The level of erosion is very light danger land unit (LU) 8 on the use of secondary dry forest on the slope of 25 40%), while other land units at the rate of moderate to severe erosion hazard
