Abstract

Forest fires which occurred during the peak of the drought is often detrimental to various parties, such as the fires that have occurred in one of the natural forest in East Java on Putuk Limas block Taman Hutan Raya (TAHURA) R. Soerjo which conduce in the status of the region become rehabilitation area. Land cover in the area lost due to forest fires so that the kinetic energy of the rain hitting the ground getting stronger due to the absence of anchoring as before the fire broke out. As a result it might just happen to surface flow and erosion in the area and allow the existence of the impact on the area below that have a lower altitude. Research conducted at TAHURA R. Soerjo to to estimate the value of erosion and to know the level of erosion hazard that occurred in the area of rehablitasi land fires in Putuk Limas Block TAHURA R. Soerjo USLE (Universal Soil Loss Equation) method. This research was carried out on December 29, 2017 to January 29, 2018 using field data retrieval method is the measurement of the slope of the land, the length of the slope, soil sampling, and then data retrieval laboratory to test results land and primary data retrieval for December rainfall data and the study of related literature. After making the measurements and data analysis, the results obtained in the area of Putuk Limas Block is thought to value erosion at the smallest on the unit 8 with a value of 1.03913 tons/ha/year are affected by land cover in the form of the State in great meadows, While the value of the biggest on the unit 5 with a value of 135.992 tonnes/ha/year influenced the length of the slopes and land cover in the form of a bad meadow. The rate of erosion hazard posed on the Putuk Limas Block lightly with the value soil erosion area of 54.90175 tons/ha/yr. fixed so that need for soil conservation efforts that are able to lower the level of danger of erosion in the area.
