| Summary: | As a country that has most of its territory in the form of oceans, the survival of
Indonesian people is very dependent on sea conditions, especially for those who
live in coastal areas. However, coastal communities often face serious challenges
due to coastal deterioration caused by erosion. One of the areas directly affected is
Pulau Untung Jawa Beach, Thousand Islands, DKI Jakarta. Therefore, it is
necessary to build coastal protection structures that can overcome damage in the
coastal areas of Untung Java Island due to erosion.
Coastal protection construction planning begins by analysing shoreline subsidence
through GENESIS. Simulations were also conducted to compare several coastal
structure options, including breakwater and groin. After that, the most suitable
structure is selected based on needs. An option to solve the problem on Untung
Java Island is a breakwater placed as far as 50 m from the coastline. This
configuration involves 3 breakwaters with a distance of 50 m between each and a
length of 75 m. This breakwater is designed with a peak elevation of +2.41 m from
the bottom of the water, using natural stone as protection.
