| Summary: | Soil can serve as a storage medium soil organic carbon (SOC) that can reduce carbon
dioxide emissions (CO2) into the atmosphere. The development of land is strongly influenced by
environmental conditions including the process of mass movement in this landslide of land that
can move soil material by the force of gravity. However, not all landslide categorized as a
catastrophic threat as landslide can help spread contains soil organic soil to the area at the
bottom, so that the bottom of the soil more fertile and productive.This research intended to find
out the characteristics of landslides, analyze the distribution of soil organic content and soil
organic content redistribution by a landslides mechanism in the Kayangan catchment. Research
methods used in this research were field survey methods, qualitative analysis, quantitative
analysis and comparative analysis. Sampling method used was stratified sampling and purposive
sampling. Stratified sampling method used to mapping land units. Purposive sampling method
used to inventory landslides data and soil sampling for analysis of soil organic carbon.
The research findings as follow: Type of landslide occur in Kayangan catchment is slide
type which consists of the constituent material rocks and thin soil horizon with the arrangement
of A and C, and forms a convex slope, it makes the slope unstable. The characteristics of soil
organic carbon in Kayangan catchment effected by the materials moving processes and chemical
component due to in vertical and also horizontal cause by water flowing, slope processes, and
land use. Slopes steepness plays role in spreading the influence of erosion factors, land use and
more or less influence in the process of decomposition of organic material. Each type of
landslides gives different effect on redistribution soil organic carbon mechanism. Slides type has
the biggest effect than slump type to redistribution soil organic carbon.
