| Summary: | Indonesia, as the world's largest archipelagic country, has coastal areas that serve
as the home for the majority of its population and play a crucial role in supporting
various industries that contribute to the country's economy. However, Indonesia's
coastal regions are also vulnerable to erosion, which poses a risk to the damage of
coastal settlements and the gradual retreat of the shoreline over the years. A
coastline protector works to safeguard coastal areas by dampening the energy of
incoming waves. Mangrove forests are among the natural coastline protection.
However, young mangroves need protection until they reach maturity and become
strong enough to dampen ocean waves effectively. A temporary protective
structure, in the form of bamboo breakwaters, is required. These bamboo pile-based
breakwaters can also be utilized as a cultivation medium for green mussels (Perna
viridis), which serves as a food source and simultaneously enhances the
effectiveness of the breakwater.
This Final Project aims to conduct a physical modeling of a natural coastal
protection system and assess its effectiveness in reducing wave heights. Data
collection was carried out by testing the model in a 2D wave flume, simulating 11
variations of random waves. The research results indicate that on average, the
coastal protection system with a combination of bamboo pile breakwater, green
mussel, and mangrove was able to reduce wave height by 28.19%. The most
effective configuration for bamboo pile placement involved using 184 piles, with a
spacing of 100 mm between columns and rows, and a breakwater width of 1500
mm. With this configuration, the coastal protection system managed to reduce wave
height by up to 30.58% from its initial height.
