Based on the results of the research, the abundance of phytoplankton at high and low tides ranged between 6.375 - 13.725 cells/l and chlorophyll-a concentrations at high and low tides ranged between 0,126 – 1,392 mg/m3. The value of diatom quotient is 1,533 which means that the waters of study area belong to the eutrophic category. The abundance of phytoplankton and concentrations of chlorophyll-a at high tide is higher than at low tide. Both show a high level relationship. }, issn = {2549-0885}, pages = {1--7} doi = {10.14710/ijfst.14.1.1-7}, url = {https://ejournal.undip.ac.id/index.php/saintek/article/view/21340} }
