Repong Damar as a Mitigation Effort for the Ulun Saibatin Landslide Disaster in the Regency of Pesisir Barat

Abstract

The background of this research is that Pesisir Barat Regency is prone to landslides, so that landslide disaster mitigation efforts are needed using the local wisdom of RepongDamar. The purpose of this study was to determine the role of RepongDamar in landslide disaster mitigation. The method used in this study is a qualitative method with a descriptive approach. The results of the study describeRepongDamar's role in landslide disaster mitigation efforts includes the role of the canopy as a water reservoir, thereby reducing the amount of rainwater that reaches the ground. The second role is that large roots will have a grip on the soil which can reduce the possibility of soil movement and increase the shear strength of the soil. The third role, evapotranspiration plays a role in reducing soil saturation, so that water does not accumulate in the impermeable layer. The existence of RepongDamar will minimize the occurrence of erosion, because RepongDamar has woody trees that have strong roots such as damar, duku, petai, jengkol, teak and durian trees.
