However, the relaxing beach development has not been done optimally. Santai beach is located in the south of Latuhalat village with an area of approximately 2 hectares. Santai beach has sandy and rocky beaches surrounded by ± 15 meters of wave barrier. around the relaxing beach location there are also residential areas. With the damage to the coastal protection structure, this area is directly adjacent to the sea, so it is often hit by waves or waves. This research begins with a survey of the research location, literature study, then measures the coastline of tidal data and wind data collection. From these data, an analysis was carried out to answer the objectives of this study. Based on the results of data analysis, it is obtained that the height of the breaking wave in the east direction (Hb) = 2.901 m, the southeast direction (Hb) = 4,670 m, the south direction (Hb) = 4.062 m. wavelength east direction (Lb) = 0.257 m, wavelength southeast (Lb) = 0.238 m south direction (Lb) = 0.247 m. and the depth of the breaking wave in the east direction (db) = 2.147 m, for the southeast direction (db) = 2.316 m, and south direction (db) = 3.006 m. In addition, from the analysis results obtained shoreline changes that occurred on this beach in 10 years caused erosion of -210.38 m at the 39th gleat. An alternative treatment that can be used is a simple breakwater
