ABSTRACT This research was conducted in March 2023 which was located in Koneng Beach, Dumai City. The purpose of this study was to determine the organic matter content and abundance of epipelic diatoms vertically and to analyze the relationship between the organic matter content in sediments and the abundance of epipelic diatoms vertically in the intertidal area of Dumai City Waters. The method used was survey method. Determination of the sampling point is done by purposive sampling method. Sampling of epipelic diatoms was carried out using a modified corer, then brought to the laboratory to identify and calculate the abundance of diatoms and the sediment samples to calculate the content of organic matter and sediment fractions. Sampling was accompanied by measurements of water quality with a brightness value of 0.57 m, temperature of 33 °C, current speed of 0.33 m/s, salinity of 28 ppt, and pH of 8.13. The results of the analysis of organic matter were in the rangebetween 2.55 – 13.38%. The results of the analysis of the sediment fraction can be described that the research location is dominated by sandy silt. A sum of 19 genera of epipelic diatoms were found in the waters of Koneng Beach, the with abundance values between 5.291 – 39.983 ind/cm2. The results of one way Anova test obtained an average value of 0.000, meaning that there was a significant difference in the abundance of epipelic diatoms among the sediment layers. The results of the linear regression test showed that the effect of sediment organic matter on the abundance of epipelic diatoms was 50.85%.
