Revitalizing the Batu Mejan Beach with Geotextile Breakwater

The erosion that occurred at Batu Mejan Beach was handled by the government by building a revetment. The protection of the revetment serves to keep the coastline from regressing again. However, at present the condition of the revetment has failured, therefore this research was conducted to investigate the failure of the structure. The results of wave analysis indicate that the wave energy that occurs needs to be reduced by building submerged breakwaters, in addition to strengthening the toe protection of the revetment. There are several types of material to make submerged breakwater, in this study selected breakwater made from geotextile called geotube. Geotextile material is chosen because it is environmentally friendly besides its implementation method is relatively easy but has a relatively short construction life. The breakwater dimension plan made from this geotube is 60 m long with 7.8 m width and 40 m wide gap.
