摘      要：Many failure cases of retaining walls caused by some factors, which are soil condition, planning design that did not meet the safety requirements, and the lack of knowledge or indecisiveness towards the selection of the retaining walls type for a specified height. In this research, the optimum height of a retaining wall of gravity wall type for sandy soil was planned. The research methodology was done by calculating external and internal stability from a stone gravity retaining wall. From the external stability analysis of 4 - 14 meters heights, it is known that the retaining wall still safe. The internal stability analysis obtained from 8 meters heights did not meet the safety requirements. Therefore, it is recommended from the research to use the height of 7 meters for the stone gravity retaining wall. The optimum height of retaining wall is planned in this research as the guidelines for engineers in planning the right retaining wall for the height as planned.
