Investigasi Instabilitas Lereng Gambut Pantai Desa Simpang Ayam Pulau Bengkalis Dengan Metode Limit Equilibrium

ABSTRACT
Indonesia is a country with the fourth largest peatland in the world..Bengkalis Regency is the second-largest regency in terms of peatland area after Indragiri Hilir Regency with an area of 856 thousand ha or 21.2% of the total peatland in Riau Province, Sumatra Island. Peat has very high water content but become brittle as it dries. This causes the peat slopes to be prone to landslides when they are again saturated with water. Landslides cause soil loss at a significant rate. This needs special attention to be reviewed considering that Bengkalis Island is directly adjacent to a neighboring country. This research is a study to better understand the mechanism of peat slope instability or collapse. This study took soil samples that make up the slopes to obtain their physical and mechanical properties. Next, a stability analysis will be carried out to determine the safety factor of the peatland at the site due to the influence of the groundwater table and other sensitive parameters using the Spencer-limit equilibrium method and Bishop-limit equilibrium method as a comparison use Slide 6 program. All of these analyzes will include sensitivity and probability analyses. The research location was taken in Simpang Ayam Village, Bengkalis Island. The groundwater level and cohesion are very sensitive parameters for the stability of this slope. The higher the groundwater level the slope safety factor decreases, while the higher cohesion will result in a greater safety factor. The stability analysis carried out on peat slopes has a relatively low safety factor at groundwater levels 0 – 1 meters below the slope surface. Slope collapse in the field happened gradually at high groundwater levels that is 0 – 0,5 m from surface of slope.
Keywords : peat slope, limit equilibrium, failure, factor of safety.
