Abstract

Erosion Hazard on Production Forest Area at Gerokgak, Buleleng, Bali The experiment about erosion hazard has been conducted at production forest area at Gerokgak, Buleleng, Bali. The aims of the research are to predict erosion and determine the erosion hazard. The method used in this research is USLE (Universal Soil Loss Equation).
