Abstract :
Erosion restraint in an open field surrounding the Citarik river (DAS) of Sukabumi regency
has an important role in the land development plan, such as agricultural construction, and the
agricultural equipment operation. Characteristics and capabilities of the soil, high precipitation, soil
type, climate and how farmers treat the soil are indicators of erosion. Citarik River has 44 km of length
which divided into 9 station points that will be the location of the research. The aim of this research is
to analyze the magnitude of soil erosion occurring at each point of the research station in Citarik River
using USLE method. Also to find the hazardous rate of erosion class at each point of the station along
the Citarik River.
Based on the research results of soil erosion analysis in Citarik River, all of the research
station points have varied erosion rate values starting from mild to very severe, from 9 research location
points the highest erosion rate was at station point 07 with 571.3 ton/ha/year, station point 29 with
630.2 ton/ha/year and station point 35 with 992.8 ton/ha/year and the lowest erosion rate was at station
point 05 with 151.3 ton/ha/year and station point 09 with 81.0 ton/ha/year. Of the 9 research locations
points, the Citarik River has erosion rate from class I to class V, the most severe class is at station 7
with a value of 639.3 ton/ha/year, station point 29 with avalue of 630.5 and station point 35 with a
value of 992.8 ton/ha/ year which belongs to class V, station point 05 with a value 151.3 ton/ha/year
and station 09 with a value of 81.0 ton/ha/year, which counted to class II.
