This research intends to investigate how big the effect of vegetation density affects the erosion rate prediction model in the upstream Kuncir watershed. The methodology consists of overlaying the cira satellite map for obtaining the level of vegetation density then analyzing the erosion rate by using the USLE method, and finally plotting in watershed map based on the risk level of land erosion that may be happened. The result is as an and erosion map of upstream Kuncir watershed and the analysis result shows that the vegetation density can decrease the land erosion rate
