Landslides are one of the natural indication of equilibrium their morphological forms, mass transfer in landslide countermeasures. Various research methods can be carried out both in general and detail. causes of landslides. The purpose of conducting the research is to identify the behavior of landslides in terms of soil / rock layers and groundwater availability with the aim of identifying potential indication of construction failure. Based on the results of the research, the landslide on the north side of KM 531 + 600 based on the results of the field identification shows that the landslide material is in the form of sandy clay with the type of landslide is creeping with a maximum landslide depth of 3m and a slope length of 30m. Recommended treatment is the construction of a retaining wall with a distance of at least 3m from the shoulder of the road combined with the arrangement of surface water flow drainage on slopes. The retaining wall is equipped with a pipe to drain groundwater with a pipe diameter of at least 2 inches and a maximum space between the pipes of 1m, and on the KM 531 + 600 drainage channel it is necessary to carry out construction rehabilitation and equipped with a sediment pond and channel construction designed to reduce flow speed Surface water.
