Keanekaragaman dan tutupan terumbu karang di Pulau Giligenting Kabupaten Sumenep Madura

INDONESIA: Terumbu karang merupakan suatu ekosistem dasar laut tropis yang terbentuk dari asosiasi berbagai biota yang hidup dalam komunitas laut tropis oleh aktifitas biologi. Terumbu karang merupakan komponen ekosistem utama pesisir dan laut yang mempunyai peran penting dalam mempertahankan fungsi pesisir dan laut. Terumbu karang berperan sebagai pelindung pantai dari hempasan ombak dan arus kuat selain itu terumbu karang memiliki nilai ekologis dan ekonomis yang cukup tinggi. Data penelitian di Pulau Giligenting Kabupaten Sumenep Madura sampai saat ini masih belum ada satupun data yang mengungkap tentang keanekaragaman jenis dan kondisi terumbu karang yang terdapat di Pulau Giligenting. Oleh karena itu penelitian ini bertujuan untuk mengetahui jenis, persentase tutupan, keanekaragaman dan pola sebaran terumbu karang di Pulau Giligenting Kabupaten Sumenep Madura. Diharapkan temuan dari penelitian ini dapat memberikan gambaran terkait ekosistem terumbu karang di Pulau Giligenting Kabupaten Sumenep Madura. Penelitian ini merupakan deskriptif kuantitatif, sampel diambil pada empat stasiun dengan menggunakan metode line intercept transect, kemudian pada masing – masing stasiun dibuat enam transek. Sampel diidentifikasi di laboratorium Ekologi Jurusan Biologi, Fakultas Sains dan Teknologi Universitas Islam Negeri Maulana Malik Ibrahim Malang. Hasil penelitian menunjukkan bahwa di Pulau Giligenting Kabupaten Sumenep Madura ditemukan 45 Spesies yang terbagi dalam sembilan Famili yaitu Acroporidae, Agariciidae, Favidae, Fungiidae, Mussidae, Pectiniidae, Pocilloporidae, Poritidae dan Helioporidae, dari genus Acropora, Anacropora, Montipora, Coeloeseris, Pavona, Favites, Goniastrea, Leptastrea, Leptoria, Montastrea, Oulastrea, Pleseastrea, Ctenactis, Cycloseris, Fungia, Loboyphyllia, Symphyllia, Pectinia, Pocillopora, Stylophora, Goniopora, Heliopora. Nilai persentase (%) tutupan lifeform terumbu karang di Pulau Giligenting Kabupaten Sumenep Madura sebesar 14,50%, menurut kriteria dari UNEP (United Nations Enviroment Programe) 1993, hal ini termasuk dalam kategori rusak/hancur. Nilai indeks keanekaragan terumbu karang di Pulau Giligenting Kabupaten Sumenep Madura sebesar 1,77, menurut kriteria dari Shanon-Wiener, hal ini termasuk dalam kategori indeks keanekaragaman sedang. Pola sebaran di Pulau Giligenting Kabupaten Sumenep Madura sebesar 0,05, menurut kriteria dari Soegianto (1994) pola sebaran tersebut Uniform atau seragam. ENGLISH: Coral reefs are tropical marine ecosystems that form the basis of the association of a variety of organisms that live in tropical marine communities by biological activity. Coral reefs are one of the major coastal and marine ecosystems that have an important role in maintaining the function of coastal and marine. Coral reefs act as coastal protection from waves waves and strong currents in addition to the coral reef has ecological and economic values are quite high. Research data In Giligenting island of Sumenep Madura until now there is still no single data reveal about species diversity and reef conditions contained in Giligenting Island.Therefore, this study aims to determine the type, percent cover, diversity and distribution patterns of coral reef on the Giligenting island of Sumenep Madura. It is expected that the findings of this study can provide an overview of related coral reef ecosystem on the Giligenting island of Sumenep Madura. This research is descriptive quantitative, samples were taken at four stations using the line intercept transect method, then on each - each made six transect stations. Samples identified in the laboratory Ecology Department of Biology, Faculty of Science and Technology of the State Islamic University of Maulana Malik Ibrahim Malang . The results showed that on the Giligenting island of Sumenep Madura. found 45 species that are divided into nine Family Acroporidae, Agariciidae, Favidae, Fungiidae, Mussidae, Pectiniidae, Pocilloporidae, Poritidae dan Helioporidae, of the genus Acropora, Anacropora, Montipora, Coeloeseris, Pavona, Favites, Goniastrea, Leptastrea, Leptoria, Montastrea, Oulastrea, Pleseastrea, Ctenactis, Cycloseris, Fungia, Loboyphyllia, Symphyllia, Pectinia, Pocillopora, Stylophora, Goniopora, Heliopora. Percentage ( % ) cover reefs lifeform on the Giligenting island of Sumenep Madura. of 14.50 % , which according to the criteria of the Environment Decree No.4, 2001, it is included in the category of damaged / destroyed. Index diversity value of coral reefs on the Giligenting island of Sumenep Madura. is 1.77, which according to the criteria of the Shannon - Wiener , it is included in the category of moderate indexdiversity. The distribution pattern on the Giligenting island of Sumenep Madura of 0.05 , which according to the criteria of Soegianto (1994 ) The distribution pattern of uniform.
