Talise Beach is a coastal area that has the potential of marine products and also as a means of tourism for the local community. Recently, Talise Beach and several areas along Palu Bay have experienced a lot of erosion by the impact of waves that threaten Country Road (Trans Sulawesi), settlements and other public places as a result of the earthquake and tsunami that occurred in 2018 with a wave height of 3-4 m which resulted in erosion and retreating of the coastline and even damaged several main road infrastructure and several other public facilities. The erosion problem is handled by constructing a Revetment-type coastal protection along the Talise Beach. The purpose of this study was to determine the height of the waves at Talise Beach, then to plan the technical design of the coastal protection structures at Talise Beach and to calculate the shear stability of the planned buildings. To test the stability of the Revetment, secondary data are needed in the form of wind data for 10 years (2011-2020), land contour data and tidal data for sea water and waves that are observed directly in the field. The results obtained from the calculation are the Hs is 4.466 meters, Ts is 4.5 seconds, the elevation of the lighthouse is 4.8 meters, the design water level elevation is 2.494 m. The revetment that is built consists of 3 layers using the main material is crushed stone.
