Youtefa Bay is a coastal area with a form of closed waters located in front of Jayapura City. The closed waters become Nature Tourism Areas. Population growth in the bay area is increasing and the rapid development activities in the coastal area, for various purposes such as settlements, fisheries, ports, tourism objects, cause increased ecological pressure on coastal and marine ecosystems and resources. This study aims to determine the potential of biological resources through an inventory and identification study, coral reef and the status and condition of coral reef ecosystem health through lifeform analysis and the Coral Death Index. Data collection on coral reef ecosystems is carried out at 2 (two) stations using the LIT (Line Intercept Transect) method. The results found overall the range of percentage of coral cover in the range between 48.44 to 50.26%, while the coral mortality index (MI) ranged from 0.19 to 0.32 at both stations. Health status and condition of the coral reef ecosystem shows poor condition (poor).Key Words: Coral reef; Line Intercept Transect; Health status; Mortality index; Youtefa bay

Penelitian ini bertujuan untuk mengetahui komposisi vegetasi dan pemanfaatan ekosistem mangrove di Kawasan Wisata Alam Teluk Youtefa, Kota Jayapura. Pengumpulan data lapangan dilakukan pada bulan Juli sampai Agustus 2015 yang terdiri dari tiga stasiun penelitian, yaitu Kampung Enggros, Kampung Tobati, dan Kampung Nafri. Teknik pengumpulan data yang digunakan adalah survey, wawancara, dan point center quarter. Hasil penelitian menunjukkan bahwa mangrove yang ditemukan di Kampung Enggros, Kampung Tobati dan Kampung Nafri adalah 10 jenis mangrove yang terdiri dari 7 jenis mangrove sejati (Acrosticum spesiosum, Avicennia alba, Bruguiera cylindrica, Ceriops decandra, Rhizophora apiculata, Sonneratia alba, Xylocarpus menkongensis) dan 3 jenis mangrove asoasiasi (Casuarina sp., Derris trifolia, Pandanus tectorius). Kerapatan relatif R. apiculata tertinggi di Kampung Enggros dan Tobati (42,5% dan 75,0%), sedangkan kerapatan relatif A. alba tertinggi di Kampung Nafri (45,95%). R. apiculata memiliki frekuensi tertinggi di Kampung Enggros, Tobati dan Nafri (42,5%, 75,0% dan 45,95%). A. alba dan R. apiculata memiliki frekuensi relatif tertinggi di Kampung Nafri (45,95%). Tingkat dominansi tertinggi adalah R. apiculata di Kampung Enggros (49,69%) dan Kampung Tobati (73,03%), sedangkan A. alba di Kampung Nafri (52,21%). Indeks nilai penting tertinggi ditemukan di Kampung Tobati untuk jenis R. apiculata 223,03%. Pemanfaatan mangrove oleh masyarakat di Kampung Enggros Tobati dan Nafri sebagai kayu bakar, bahan bangunan, bahan obat-obatan, bahan pengawet jaring, serta bahan dempul dan cat perahu. Biota laut yang dimanfaatakan sebagai bahan makanan yaitu ikan (4 jenis), kepiting (3 jenis) dan kerang (5 jenis).Kata Kunci: Komposisi vegetasi; Pemanfaatan mangrove; Masyarakat lokal Papua; Taman Wisata Alam; Teluk Youtefa
