Sustainability Analysis Management of Coral Community and Gili Genting Island Sumenep Madura, Indonesia

This study aimed to identify the condition of coral lifeforms and the sustainability of tourism management on Gili Genting Island, Madura. The data used are from surveys and questionnaires conducted in July and August 2024. The research employed both qualitative and quantitative methods, utilizing the Underwater Photo Transect technique at 4 stations for coral assessment, and the sustainability status of the island's tourism using Multidimensional Scaling (MDS) with a modified version of the Rapid Appraisal Index Rap-fish, called Rap-island. The evaluation was based on five dimensions: ecological, economic, social, legal-institutional, and infrastructure. The results showed that the highest percentage of live corals was found at station 4, at 83.02%, followed by station 3 at 82.06%, the lowest being at station 2 with 65.36%, and station 1 with 66.8%. The lifeforms identified consisted of 5 species of Acropora and 7 species of non-Acropora. Acropora Branching dominated with 34.69%, while non-Acropora was dominated by Coral Massive at 7%. The percentage value of lifeforms from Underwater Photo Transect was 55.37%, which is higher than the Line Intersect method, which only reached 13.54%. The sustainability status of Gili Genting Island's tourism is categorized as moderately sustainable (55.7). The index values for the five dimensions are as follows: ecological dimension, moderately sustainable (74.7); economic dimension, less sustainable (49.07); social dimension, moderately sustainable (53.6); legal and institutional dimension, less sustainable (46.7); and infrastructure dimension, very sustainable (83.5).
