No management of topsoil, the base relief excavation is more than 1 meter, the average wall slope is 55o (142,81%), the height of the excavation wall with an average of ±5,6 meters and land cover/vegetation reaching 33,35%. The technical design will be used is making bench terraces and making drainage channels. The plants used as revegetation are sengon, jackfruit and vetiver grass as cover crop plants.
