ANALYSIS OF METAL Pb AND Cu CONTENT IN SEAGRASS (Sargassum sp) IN BAYUR BAYS OF WEST SUMATERA PROVINCE

Located in Teluk Bayur bay the port is of five biggest and busiest ports Indonesia. High sea transportation activities anthropogenic may lead to heavy metal pollution. The purpose this study was determine concentration Pb Cu metals, seagrass (Sargassum sp.) analyze feasibility consuming Sargassum sp. method used a survey method, by analyzing at Laboratory Pekerjaan Umum Riau Province. water quality temperatures 30-31oC, salinity 30-31 ppt, appeared curred velocity 0.06-0.08 m/sec, transparency 100% with depth ± 1 m pH 7. concentrations highest 2.9367 μg/g stations close lowest 2.2506 tourist areas, shows 3.3850 community settlements, 2.7772 near area ​​Teluk Bayur. Based on PTWI value, those originating from waters Bayur, West Sumatra, are still safe for consumption. Anova tests do not different (p> 0.05).
