Abstract

This research was conducted in June 2015 with the aim was to knowing the concentration of heavy metals of Pb, Cu and Zn accumulated in the albumen and yolk of olive ridley sea turtle (Lepidochelys olivacea) from Pariaman town beach, West Sumatra Province. The method used was a survey conducted on 3 beaches. The results showed that the average metal Pb in albumen (2.7644 μg/g) was greater than the metal Cu (2.0970 μg/g) and smaller than the metal Zn (10.4924 μg/g). While metal Pb in yolk (6.8008 μg/g) was smaller than the metal Cu (7.0357 μg/g) and metal Zn (34.1479 μg/g). The PTWI calculation value (the Provisional Torelable Weekly Intake) based on FAO/WHO standard for an adult weighing of 70 kg told that the eggs were still reasonably consumtable as long as it did not exceed the limit of 3.2932 kg/week for Pb, 482.8780 kg/week for Cu and 197.5793 kg/week for Zn. However, consumsing turtle eggs continuously can harm the body’s health and threaten the sustainability of turtles in the wild.

Abstract

The research was conducted in January – March 2016 in coastal waters of MalangRapat, Bintan Regency, Kepulauan Riau Province. The aims of this study were to determinethe nutrient content of sediment in seagrass ecosystem and to determine the ratio of N:P inthe sediments by different of antropogenic and determine the relationship of nutrient withdensity and biomass of seagrass. The parameters measured were included physical andchemical 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 ofN:P in the sediment was total of nitrogen by Kjehdahl method and phosphorus total withDouble 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 seagrassin the coastal of Trikora Beach Malang Rapat was 54.78–56.33 shoots/m2 and biomass ofseagrass was 261.37–275.65 g/m2. Station II had a ratio of N:P = 44:1 and provided goodleverage, this can be indicated also by the total biomass and density of seagrass at this stationwas the highest. The Nitrogen and Phosphorus in the sediment with density and biomass ofseagrass had a very weak relationship, there are other factors that might affect the density andbiomass of seagrass in which were not measured in this study.Keywords: Seagrass Ecosystem, Density, Biomass, Rasio N:P, Sediment, Trikora Beach
