OWEC breakwater is a coastal structure with an integrated concept of the breakwater and overtopping wave energy converter. This breakwater WEC concept (OWEC breakwater) model has a reservoir at the rear of the breakwater peak. This reservoir serves to catch and collect overtopping waves that overflow through the top of the breakwater. The amount of overtopping discharge is influenced by many factors, one of them is the characteristics of the incoming wave, including the characteristics of the breaking wave on the surface of the structure, named the breaker parameter. The effect of wave reflection coefficient to the breaker parameter on OWEC (overtopping wave energy converter) breakwater is investigated experimentally as a preliminary study. The study is carried out in wave flume with regular waves. The OWEC breakwater model is simulated with slope variations and freeboard variations. The result showed that most of the breaker parameter types obtained are plunging (0.4 2), the result also showed that the higher the value of reflection coefficient, the higher the value of the breaker parameter.
