- Bentos have the important role in human live, for example as food source, as one of the food chain organism, and also bioindicator of marine pollution. It’s show seagrass beds have a lot of potential to be useful by the people for rising production of fisheries. The aims of this study were to analyzed relation between density of seagrass beds and community structure of macrozoobentos. This research was done in Mei 2017, used purposive sampling method by observating of seagrass vegetation, macrozoobentos, measurement of water quality and type of substrate analysis. 3 species of seagrass was found in seagrass beds with density at Station I 133 ind/m2, II 125 ind/m2, III 41 ind/m2, and IV 109 ind/m2. 22 species of macrozobentos was found at the research site. Density of macrozoobentos at Station I 6,115 ind/m2, II 2,785 ind/m2, III 1,957 ind/m2, and IV 5,469 ind/m2. Regresion analysis was show by equation y = 14,083x + 44,448 with R2 = 0,4655 and r = 0,6822 relationship between seagrass density and macrozoobentos density are strong. Which means any increase in seagrass density will affects 46,55 % with macrozoobentos density.Keywords : Seagrass, Macrozoobentos, Community Structure, Unggeh Island
