MENENTUKAN NILAI ERODIBILITAS TANAH (K) PADA JENIS TANAH DI SUB DAS JENELATA

Abstract

The purpose of this study is to determine the value of soil erosion for each type of cultivation in several land units (K) in Jenelata Subdistrict, Gowa Regency, South Sulawesi Province. The Jenelata watershed is part of the Jeneberang watershed, located at 05º15'40'' - 05º25'50'' S and 119º34'45'' - 119º49'48'' E, with an area of approximately 23,733 hectares. The Jenelata watershed lies between 25 and 1375 meters above sea level. Most of the residents in the Jenelata watershed earn their livelihoods from farming and gardening. The types of land use in the Jenelata watershed include rice fields, mixed gardens, production forests, and grasslands. In the Jenelata watershed, the dominant trees are mahogany, white teak, and bamboo, while the dominant food crops/plantations are rice, corn, cassava, and cocoa. The results of the study show that cultivation activities have a significant impact on soil erosion, and the values of soil erosion were obtained from field data
