Abstract
Ekosistem lamun adalah salah satu ekosistem laut dangkal yang mempunyai peranan penting dalam kehidupan biota laut dan merupakan salah satu ekosistem bahari yang paling produktif. Ekosistem lamun saat ini kurang mendapat perhatian dikarenakan kurangnya pengetahuan masyarakat tentang fungsi ekosistem lamun. Akibatnya, upaya masyarakat dalam menjaga kelestarian ekosistem ini sangat minim bahkan terkadang dianggap sebagai tanaman pengganggu, sehingga akhirnya diabaikan atau dimusnahkan. Penelitian in bertujuan menjabarkan kajian ekologi struktur komunitas lamun di perairan Dusun Ketapang, Kecamatan Sekotong Barat, Kabupaten Lombok Barat. Metode yang digunakan dalam penelitian ini adalah percobaan langsung di lapangan dengan mengguanakan teknik pengambilan contoh secara purposive sampling Pengamatan struktur komunitas lamun menggunakan transek kuadran berukuran 50x50 cm dengan jumlah stasiun yang ditetapkan sebanyak 3 (tiga) stasiun. Jarak dan tata letak stasiun berdasarkan pendekatan habitat mangrove, lamun, dan terumbu karang dengan pengulangan sebanyak tiga kail, sehingga dalam penelitian ini terdapat 9 (sembilan) transek kuadran. Adapun terkait pengukuran kualitas air dilakukan secara in situ. Hasil penelitian menunjukkan bahwa terdapat 4 jenis lamun, yaitu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, dan Halophila ovalis. Struktur komunitas lamun seperti kerapatan, frekuensi, dan penutupan maupun kontribusinya di perairan Dusun Ketapang didominasi oleh jenis Cymodocea rotundata.

期刊介绍:
The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
