[email protected] Abstract The analysis this research aims to determine whether or not a safe beach building located in Bambaloka Pasangkayu Regency, to the strong stability of soil support, shear and rolling and this study aims to determine the type of beach safety building suitable for Bambaloka beach. From the results obtained based on the analysis carried out, it can be concluded that there are several things concerning the stability analysis of the beach safety building (Breakwater) located on the coast of Bambaloka, Baras District, Pasangkayu Regency, West Sulawesi. It can be summarized as follows, force against wave, l_c = 0.7 m, l_t = 0.17 m, stability of coastal protection building against soil bearing strength σ_maks = - 44.4 kN / m² <q_a = 7.393 kN / m² (safe) Stability of Breakwaters to shear and rolling Against shear = 0 <2 (Safe) Against rolling = 0.116 <2 (Safe). Keywords: Analysis, Breakwater, Slide, Bolster, Stability, Beach Safety.
