Abstract: This research presents an evaluation of the design and stability of a seawall at Laompo Beach, Sulawesi, Indonesia, to protect a nearby highway from coastal erosion. Preliminary dimensions with some secondary data on wind, tidal, and soil bathymetric data have been carried out. This includes a wall height of 4 m, foundation width of 2.8 m, foundation height of 0.7 m, and top embankment width of 1 m. The stability analyses using the limit equilibrium method indicate that the embankment satisfies the safety criteria under static, dynamic, and scour conditions. The research highlights the importance of precise design considerations, including wave forecasting and stability analysis, for constructing durable seawalls. This paper emphasizes overall coastal engineering to reduce the effects of erosion on critical infrastructure and the need for high-quality construction and maintenance to ensure the long-term efficacy of these structures, providing valuable guidance for developing safe and effective coastal protection measures. This work is singular, as the advanced geotechnical analysis tools have been implemented in the context of a real-world coastal protection scenario in a developing region
