Abstract

This research was conducted in July 2020 in Pelintung Dumai Waters. The purpose of this study was to determine the relationship between total oil concentration and the abundance of phytoplankton. The method used is a survey method which is conducted at 4 stations. Based on the results of the study, the highest oil concentration was in the waters of the Pelintung industrial area (station III), namely 0.3245 ppm and the lowest concentration was in the mangrove forest area (station IV), namely 0.0738 ppm. There are 21 species of phytoplankton found in Pelintung waters. The highest abundance was found in the tourist area (station I) which was 166 ind / l and the lowest abundance was found in the mangrove forest area (station IV) which was 138 ind / l. The relationship between total oil concentration and phytoplankton abundance is negative, which means that every time there is an increase in total oil concentration, there is a decrease in the abundance of phytoplankton in Pelintung waters

Abstract

This study aims to determine the distribution of total suspended solid concentration (TSS) in the waters around TPI Dumai. Water samples were taken from 12 sampling point from the waters during high and low tides to determine TSS concentration. The concentration of total suspended solids ranges from 60-130 mg/l. The concentration is relatively higher (>80 mg/l) in the area that is close to residential areas and TPI. The highest concentration of total suspended solids was 117 mg/l found in waters with a depth of 1-3 m, while the lowest was 81 mg/l found at the sampling point of 5,9. The distribution of chlorophyll-a concentration is relatively higher around the coast which is around 0.476-0.178 mg/l, and it's lower off the shore which is around 0.080-0.090 mg/l. The chlorophyll-a concentration is lower in waters far from the coast because there is no direct nutrient supply from the land. The regression analysis indicate that Tss and chlorophyll-a has a weak relationship between the two variables relatively weak but they are still affecting each other
