Abstract
Watershed is a vulnerable environment for soil erosion to occur. High intensity rainfall causes high river water overflowed and eroded rocks as well as soil in river banks referring to landslide. Cigentis is upstream area of Citarum watershed which is functioned to arrest the water flow at the upstream in Mekar Buana, Karawang. This study aims to analyze landslide countermeasures by applying slope reinforcement and drainage refinement to prevent recurrence of slides. The methods used are survey investigation, laboratory test, stability analysis for slope reinforcement utilizing PLAXIS2D and drainage refinement. The river banks are strengthened by applying gabion mesh retaining wall. The gabion mesh dimensions are 2.5m in length; 1m in width as long as 33m. The result indicates the safety factors for existing condition 1.23 while the safety factor for strengthening condition 1.79. It can be concluded that the condition of river banks with reinforcements is in safe conditions.
