Abstract
The development of the Minahasa East Coast area into a tourism area has caused a tendency to change land use. Kombi Subdistrict is one of the areas on the East Coast of Minahasa that has experienced changes in land use with many investors building tourism areas there. The rate of land clearing in the area can accelerate the process of erosion. This research was carried out with the aim of knowing the level of soil erosion hazard on the East Coast of Minahasa, especially in Kombi District, in order to prevent soil damage so that environmental sustainability can be maintained and the development of tourism areas in the area can continue. The method used in this research is the overlay method for making digital maps and calculating erosion using the USLE method. The results of the analysis show that the Minahasa East Coast area, especially in Kombi District, has a light erosion hazard level of 1492.10 Ha, a moderate erosion hazard level of 5036.35 Ha, and a severe erosion hazard level of 6970.94 Ha.
