Abstract

The research area located in the Sidodadi area and its surroundings, South Ogan Komering Ulu Regency, South Sumatra Province is included in the South Sumatra Basin. In this research, the study includes remote sensing with GIS, as well as geomorphological analysis using morphometric parameters, such as: Valley Floor Width to valley height ratio (Vf), Mountain front sinuosity (Smf), Hypsometric Curve and Hypsometric Integral (HI), Drainage Density (Dd). ), Assymetry Factor (AF) and Tectonic Activity Index (IAT). The results of IAT calculations have concluded that the Sidodadi area and its surroundings are included in class one to three tectonic activity or the category of moderate to very high tectonic class. The research area also has a river flow pattern which is dominated by a parallel flow pattern controlled by geological structures. Based on the results of this analysis, it can be concluded that the Sidodadi area and its surroundings were formed by tectonic activities that affect the formation of morphology found at this time and affect surface processes such as denudation and erosion, which can pose a risk of soil movement or landslides.
