Abstract
Abstrak
Lamun (Seagrass) merupakan salah satu ekosistem penting diwilayah pesisir yang
berperan penting baik secara ekologis dan ekonomis. Keberadaan lamun mendukung
kehidupan berbagai jenis biota laut. Penelitian ini bertujuan mengidentifikasi jenis-jenis
lamun yang berada di perairan pantai Rua, Mengetahui kepadatan, pola sebaran,
keanekaragaman jenis, dan dominansi serta asosiasi antara spesies. Penelitian ini dilakukan
dengan metode garis transek dan kuadrat. Hasil penelitian menunjukkan bahwa terdapat 4
jenis lamun di perairan pantai Rua yang terdiri dari Cymodocea rotundata, Enhalus
acoroides, Halodule pinifolia dan Thalassia hemprichii. T. hemprichii adalah jenis dengan
kepadatan tertinggi di perairan Rua yaitu 16,70 ind/m2, serta E. acoroides, memiliki
kepadatan terendah yakni 5,77 ind/m2. Jenis lamun yang ditemukan di lokasi penelitian
seluruhnya memiliki pola sebaran mengelompok dengan keanekaragaman yang
dikategorikan rendah yaitu sebesar 1,32, serta indeks dominasi sebesar 0,27. Tipe asosiasi
lamun di lokasi penelitian yaitu asosiasi positif (+), serta asosiasi negatif (-).

Abstract
Seagrass is a important ecosystems coastal region that is important both ecologically and
economically . The seagrass supports of various marine life. This study to propose identify the
species of seagrasses in coastal waters in Rua, Knowing the density, distribution pattern,
species diversity, and dominance as well as associations between species. This study was
conducted using line transect and kuadrats. The results showed that there are 4 species of
seagrass in Rua consisting of Cymodocea rotundata , Enhalus acoroides , pinifolia Halodule
and Thalassia hemprichii . T. hemprichii is highest density (16.70 ind/m2), and E. acoroides ,
which has the lowest density (5.77 ind/m2). Species seagrass found in the research area all
have clumped distribution patterns are categorized with diversity low at 1.32 , and dominance
index at 0.27. Type association of seagrass in the location studies is positive association ( + )
and negative association ( - ).
