Abstract
Terumbu karang di Indonesia merupakan salah satu ekosistem utama di wilayah pesisir dan laut dengan lebih dari 569 jenis karang, membuat Indonesia menjadi negara dengan tingkat keanekaragaman terumbu karang tertinggi di dunia. Sebagai ekosistem produktif dengan potensi ekonomi dan ekologi yang tinggi, keberadaan dan kelestarian ekosistem terumbu karang harus dikelola secara berkelanjutan. Salah satu kawasan dengan keanekaragaman terumbu karang yaitu Pulau Giligenting Kabupaten Sumenep.
Penelitian ini dilakukan dengan pengambilan data primer berupa data pasang surut, data batimetri dan rekaman Side Scan Sonar. Dari data primer kemudian dilakukan pengolahan yang menghasilkan model tiga dimensi fitur dasar laut yang kemudian di analisa untuk mendapatkan kondisi dari terumbu karang.
Model tiga dimensi yang dihasilkan memiliki kedalaman maksimal 7,667 meter dan kedalaman minimal 1,403 meter seluas 100.536,097 m2. Dari interpretasi Citra Akustik SSS ditemukan luas dari fitur pasir sebesar 30,79%, fitur lumpur sebesar 29,94%, fitur terumbu karang barrier reef sebesar 10,09%, fitur terumbu karang tepi sebesar 25,66% dan fitur terumbu karang rusak sebesar 3,52% dari total area survei SSS seluas 43.527,110 m2.

Coral reefs in Indonesia are one of the major ecosystems in the coastal region with 569 coral species, making Indonesia as the country with the highest coral reefs biodiversity in the world. As productive ecosystems with high economic and ecological potential, the existence of coral reef ecosystems must be sustainably managed. One of the areas with high diversity of coral reefs is Giligenting Island located in Sumenep regency.
This research was conducted by taking primary data in the form of tidal data, bathymetry data and Side Scan Sonar recordings. From the primary data and then performed the processing that produces 3 dimensional model of seabed features that are then analyzed to obtain coral reefs conditions.
The resulting 3-dimensional model has a maximum depth of 7.667 meters and 1.403 meters at minimum depth, with an area of 100,536.097 m2. From the interpretation of SSS acoustic images it is found the area of sand feature is 30.79%; the area of mud feature equal to 29.94%; the healthy coral covering 35.75% of the area, consisting 10.09% of coral reef barrier reef feature, and 25.66% of fringing coral reef feature; and 3.52% of damaged coral reef feature from total 43,527.110 m2 SSS survey area.
