【 摘 要 】

This research aims to analyze a characteristic of liquid limit and plasticity index of soil to predict soil susceptibility on landslides area in four districts of South Sulawesi which has a high intensity of landslides event. Soil sampling was done in sixteen soil profile on A, B, and C horizon. The experiment used a split-split plot design with three replications. The ASTM-D method was used for calculating the liquid limit, plasticity limit and index plasticity. The average value of liquid limit in landslides area was 67.91%, plasticity limit was 52.22%, and index plasticity was 16.23%. Statistical test showed a correlation between landslides event with soil characteristic on each horizon with significant at P
