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

This study is to determine the relationship between primary productivity and nutrients in the coastal waters of Pelintung Village, Medang Kampai District, Dumai. The research was conducted in March 2022; the method used in this research is survey method and purposive sampling. The research location is divided into 3 station points namely tourist area, secondary vegetation forest area, and near industrial area. The results of the measurement of the highest primary productivity value are found at Station III which is 78.91 mgC/m2/hour which indicates mesotrophic water conditions, while the lowest primary productivity value is at Station II, which is 46.88 mgC/m2/hour which indicates oligotrophic water conditions. The results of the analysis of the concentration of nitrate and phosphate between stations also varied, namely for the nitrate value of 0.04 – 0.05 mg/L which was included in the less fertile category, while the phosphate concentration was 0.042 – 0.048 mg/L which was included in the fertile category in the waters. Furthermore, the relationship between nitrate concentration and primary productivity is a correlation coefficient value (r) = -0.070 which means that there is a weak relationship between nitrate concentration and primary productivity. Meanwhile, the relationship between phosphate concentration and primary productivity is the correlation coefficient (r) = 0.965, which means that there is a very strong relationship between phosphate concentration and primary productivity. So it can be concluded that nitrate and phosphate nutrients can affect the primary productivity of water.

Microplastics are the result of degradation and fragmentation originating from plastics with a size of <5 mm. Currently, many people use broiler chicken intestines which are possibly contaminated by microplastics as food for pomfret (Colossoma macropomum) in floating net cages (KJA). The purpose of this study was to determine the number and type of microplastics present in the intestines of broiler chickens and the digestive tract of pomfret cages (C. macropomum) and to see the correlation level of the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed using intestines. broiler chicken. The method used in this study was purposive sampling for the sampling of pomfret cages (C. macropomum). A sampling of broiler chicken intestines was carried out at random from KJA fish cultivators in Teluk Kenidai Village. The results obtained were microplastics of film type, fiber, and fragments found in the intestines of broiler chickens and the digestive tract of pomfret (C. macropomum). The number of microplastics found in broiler chicken intestines was 322 film particles, 112 fiber particles, and 52 fragment particles. While in the digestive tract of pomfret (C. macropomum) 343 are film particles, 203 fiber particles, and 63 fragment particles. The relationship between the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed with broiler chicken intestines has a very strong relationship with a correlation value of 0.952.
