THE RELATIONSHIP OF PRIMARY PRODUCTIVITY OF PHYTOPLANKTON WITH OCEANOGRAPHIC PARAMETERS IN THE WATERS OF LUBUK GAUNG SUB-DISTRICT, SUNGAI SENIN DISTRICT, DUMAI

The waters of Lubuk Gaung Village, Sungai Sembilan District are areas that widely used as transportation routes. Activities in these will cause environmental pollution, which affects the life phytoplankton. purpose this study was to determine relationship between primary productivity phytoplankton with oceanographic parameters District, Dumai. method is survey research station and situ for measurement sampling parameters. results obtained Oceanographic from three stations, namely Brightness = 30 – 49 cm, Turbidity 47.4 58.4 FTU, TSS 124 209 mg/L, BOD 0.408 1.224 mg/L. average value ranged 48.07 79.69 mgC/m3/day. at II categorized into Oligotrophic, low waters. Stations I III mesotrophic waters, medium brightness, turbidity, has a very strong positive (unidirectional) correlation value. negative (opposite) correlation.
