ANALISA KERENTANAN TANAH LONGSOR MENGGUNAKAN METODE FREQUENCY RATIO DI DESA SRI MENANTI, KABUPATEN OKU SELATAN, SUMATERA SELATAN

---

The research was in Sri Menanti Village, Mekakau Ilir District, South OKU Regency, South Sumatra, the research area is in the volcanic arc route. The research is aimed at identifying Landslide Susceptibility in the research area based on Geomorphology, Stratigraphy and other parameters with the aim of reducing the impact of losses. The research was carried out using a frequency ratio analysis method based on landslide occurrence data against selected parameters in the form of spatial data. The parameters chosen are slope slope, slope shape, slope direction, rainfall, land cover, rock formations, and distance to the river. The Sri Menanti area and its surroundings are an area composed of 4 rock formations with a predominance of volcanic rock, with land cover dominated by mixed dry land agriculture, moderate rainfall with a value of 1500 - 3000 mm/year, steep to very steep slopes with concave and convex slope shapes, The slope direction covers all cardinal points and the distance to the river is dominated by a distance of 0 to 400 m. Sri Menanti Village and its surroundings were identified as having low to high levels of landslide vulnerability with a predominance of the high class based on the frequency ratio method. The data validation results are worth 0.8 which shows that this method is accurate to use.
