Abstract: The main problem in the Indonesian Ocean, especially along the west coast of Sumatra to the south coast of Java, is wave height. High sea waves can damage coastal areas. One method of mitigating this issue is the use of breakwaters, which function as wave energy dampers in specific areas. Large wave impacts can be reduced by decreasing the incoming wave energy so that waves approaching the coast have less energy. Therefore, a wave breaker construction is necessary to break and transmit wave energy effectively. This study aims to determine the transmission coefficient (Kt) value through physical model testing. The results from the physical model test indicated a transmission coefficient of 0.621 with the MU1A d50 L137 draft10 f0167 A010 test model /Regular Wave. The research findings suggest that a floating breakwater with a mooring system, placed at a depth of d50 with a draft of 10 cm (half submerged), can dampen wave energy when affected by regular waves, demonstrating its effectiveness in wave energy reduction.
