Sempor reservoir is located in Kebumen Regency of Central Java Province, Indonesia. This reservoir is the strategic asset that play a crucial role in providing water for various needs. Currently, Land farming activities in the upper stream area tend to aggravate sediment problems.However, the way to solve this crucial problem hasn’t found yet due to the increasing of sediment yield.The aim of this study is to determine the significant variable which controls sedimentation through appropriate land allocation. Several scenarios are applied on determining the significant of sediment control. Period of time and the capacity of land use are also taken into account in this research. Landuse arrangement is designed by changing permanent vegetation cover into the other types of appropriate vegetations around 4% up to 30%. Formulas of Meyer-Peter and Müller as well as regression equations will be used to calculate the sedimentation. While, erosion will be simulated for ten years (2001 – 2011) using USLE equation then be supported by Arc GIS software. The results show that the increasing of permanent vegetation cover can reduce the sedimentation significantly.
