Biomassa Dan Kerapatan Lamun Berdasarkan Rasio N:P Pada Sedimen Di Perairan Pantai Trikora Kabupaten Bintan Provinsi Kepulauan Riau

The research was conducted in January – March 2016 in coastal waters of Malang Rapat, Bintan Regency, Kepulauan Riau Province. The aims of this study were to determine the nutrient content of sediment in seagrass ecosystem and to determine the ratio of N:P in the sediments by different of antropogenic and determine the relationship of nutrient with density and biomass of seagrass. The parameters measured were included physical and chemical parameters of marine waters. The density was computed using a quadratic transect, while seagrass biomass was calculated by measuring dry weight of shoot. The value ratio of N:P in the sediment was total of nitrogen by Kjehdahl method and phosphorus total with Double Acid method. The results showed the average nitrogen content was 0.003621–0.003966% and the average phosphorus was 0.000036–0.000090%. The density of seagrass in the coastal of Trikora Beach Malang Rapat was 54.78–56.33 shoots/m2 and biomass of seagrass was 261.37–275.65 g/m2. Station II had a ratio of N:P = 44:1 and provided good leverage, this can be indicated also by the total biomass and density of seagrass at this station was the highest. The Nitrogen and Phosphorus in the sediment with density and biomass of seagrass had a very weak relationship, there are other factors that might affect the density and biomass of seagrass in which were not measured in this study. Keywords: Seagrass Ecosystem, Density, Biomass, Ratio N:P, Sediment, Trikora Beach.
