| Abstrak Erosion can be caused by natural activities or human activities. Erosion events that occur naturally do not cause too many problems, but erosion events caused by humans can cause various problems of land damage or degradation and experience an accelerated rate of erosion. The Dolago watershed has an area of ±17,283.09 ha and is a priority watershed that needs attention because several natural disasters such as erosion, landslides and floods have harmed the community when rainfall increases. Based on the case above, researchers studied the erosion risk class of the Dolago watershed by combining erosion prediction methods, namely USLE and Geographic Information Systems. Erosion hazard class research was carried out in the Dolago watershed for 3 months, from September to November 2022 using the Universal Soil Loss Equation method and Geographic Information System, namely Overlay (Overlay) of several data (erosion determining parameters) to determine the erosion hazard class in the watershed Dolago. From the results of research using the Geographic Information System and the Universal Soil Loss Equation method, it shows that the amount of eroded soil in the Dolago watershed is 23,888.80 tons/ha/year and the erosion hazard class is divided into 5 classes, namely Class I (very light) erosion rate <15>480 tonnes/ha/year with an area of 259.49 ha. |
