The purpose of this study was to determine the effect of the tides on the abundance, composition of phytoplankton, chlorophyll-a and to determine the quality of the aquatic environment by phytoplankton and chlorophyll-a levels. This was a descriptive study and purposive sampling method was applied to collect samples. Sampling was carried out in three stations, three replications at high tide and at low tide. Abundance of phytoplankton and chlorophyll-a were analyzed using factorial ANOVA. Phytoplankton during high tide and low tide was composed of 4 classes i.e. Baccilariophyceae, Chlorophyceae, Cyanophyceae and Dinophyceae, whereas 15 genera at high tide and 19 genera at low tide. Phytoplankton abundance in high tide were 1.124 – 1.678 individuals/L, whereas in low tide were 1.151 – 3.863 individuals/L, chlorophyll-a in high tide ranged from 0,11 to 0,54 µg/L and at low tide were 0,12 to 2,14 µg/L, SI ranged from 0,5 to 1 and TSI ranged from 1,07 to 1,49. Factorial ANOVA showed significant interaction between ebb and stations to chlorophyll-a. Based on the abundance of phytoplankton and chlorophyll-a waters were classified to be oligotrofik until mesotrofik and based on the value of SI and TSI was classified as moderate polluted waters. }, issn = {2721-6233}, pages = {92--101} doi = {10.14710/marj.v3i2.5007}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/5007} }
