Abstract

The quay is ideally free from wave interference so ships can dock to rise and fall of passengers or loading and unloading goods safely and comfortably. The harbours that open directly to the ocean without being protected by breakwaters are quite vulnerable to unfriendly weather when very high wind speed occurs high sea waves rise very high can lead to the process of relying on the ship on rise and fall of passengers or loading and unloading goods cannot be done safely and comfortably. Generally the size of the gravitational breakwater increases with the depth of the water, starting from the base of a large foundation and requiring an enormous amount of construction material if it is built in deep water, so this breakwater type are expensive in deeper water.The curtainwall pile breakwater is one of partially barrier breakwater types, that requires less concrete per-unit run and capable of transmitting less wave energy. Research on curtaianwall-pile breakwater (CPB) and the same types has been done by many researchers, but there is no research on CPB equipped with protection base to protect the pile from wave scouring. The experimentally study has be done in wave flume with physical model. The size of the wave flume are length 15 meters, depth 0.45 meters, and wide 0.30 meter that equipped with wave maker, damper, and wave probe. The purpose of study investigate transmission wave coefficient () and reflection wave coefficient () CPB effect of the bottom protection with low rubble-mound. Based on the result of study is known that the curtainwall pile breakwater (CPB) with bottom protection give transmission wave coefficient () more less (decrease value: 0.04 – 0.22) than CPB without bottom protection and give reflection wave wave coefficient () larger (increase value 0.07) depend value of h/d. The generally curtainwall pile breakwater (CPB) without bottom protection, if the value h/d and H/L increase, transmission wave coefficient () will decrease and reflection wave coefficient () will increase. The value = 0.91 – 0.42 and = 0.26 – 0.65 depend h/d and H/L.
