<![CDATA[Abstract This research aims to assess the value of soil erodibility in the Mount Masarang Protected Forest area Rurukan Village, Tomohon City. The research was conducted on 3 types of land cover, namely grasses/reeds land, agricultural land and secondary forests. For each type of land cover, 3 soil samples were taken. Soil sample points were determined purposively, the soil structure was observed and the soil permeability was measured using a permeameter with the constant water level method (Constant Head). Soil samples were analyzed in the laboratory to obtain data on soil texture and soil organic matter content, then K value was calculated according to the USLE method. The results showed that the highest soil erodibility was on agricultural land at 0.37 ton.jam.ft-tonf-1 .in-1 which is classified as a rather high class, while the lowest was on grass/reed land of 0.19 ton.jam.ft-tonf-1 .in-1 belongs to the low erodibility class. Factors causing high soil erodibility on agricultural land were a low clay content, higher silt and lower organic matter so that the soil is more easily eroded.Keywords: soil erodibility, protected forest, Mount Masarang.]]>
