Abstract

Land use change that penetrate green area causes critical land. Critical land causes increase the erosion. Moreover, infrastructure development is increasing in the Tapalkuda area (Probolinggo, Lumajang, Jember, Bondowoso, Situbondo, and Banyuwangi). If erosion is higher, it will have an impact on the quantity and quality of water. For that, this research aims to analyze the effect of land use for erosion rates on 16 watershed of Tapalkuda in East Java using USLE method (Universal Soil Loss Equation) and GIS. The erosion rate was calculated based on the erosivity faktor (R) calculated from analysis of rainfall data, crop factor (C) and land use map analyzed by land use map 2014, the length and slope faktor (LS) calculated from the ASTER GDEM2, and erodibility faktor (K) obtained by soil type map. After the erosion rate was obtained, the comparised between erosion rate and land use that carried out using a correlation coefficient. The factor of land use analyzed are rice fields, settlements, fields, gardens and bushes.
