Puger Beach located in Puger Village, Jember Regency which is often passed by fishing boats to Puger Fish Market. The problem of high waves is often experienced by fishermen. In 2014, a breakwater was built in the estuary of Puger Beach to overcome the problem. However, the construction of the breakwater is considered not optimal because the layout of the building only dampens waves from the west. Based on this background, this study aims to model the sea waves that occur in the estuary of Puger Beach due to the influence of the breakwater layout. Waves were modeled based on the dominant wind direction at the study site: southwest, west, and south. Modeling was made using Delft3D software by creating five breakwater placement schemes. The modeling results obtained southwest, west, and south respectively are: the first scheme reduced the wave height by 31.01%, 27.33%, and 37%; the second scheme reduced the wave height by 28.95%, 31.59%, and 36.63%; the third scheme reduced the wave height by 78.12%, 82.08%, and 65.32%; the fourth scheme reduced the wave height by 79.91%, 47.28%, and 76.54%; the fifth scheme reduced the wave height by 94.53%, 99.78%, and 96.78%. |
