Levels Of Water Fertility In Coastal Waters Of Kuri Based On Phytoplankton Chlorophyll-A Concentration

This research aims at analyzing the level of water fertility based on the concentration of chlorophyll-a phytoplankton in coastal waters of Kuri, Maros regency, South Sulawesi, Indonesia. Sampling chlorophyll-a phytoplankton was carried out on three stations. These three stations have different environmental characteristics. Station I is the Mambue estuarine, the station II is an estuarine Kuri Lompo, and the station III is Marusu estuarine. The concentration of chlorophyll-a phytoplankton was analyzed using a trichromatic method. Analysis of one way ANOVA is done to see the difference in the concentration of chlorophyll-a between stations. The level of water fertility based on the content of chlorophyll-a phytoplankton was analyzed using the category of fertility levels described by Hakanson and Bryann (2008). The results showed that the concentration of chlorophyll-a based on the station was showing no difference in the 95% confidence hose (alpha = 0.05). The level of water fertility based on chlorophyll-a phytoplankton is relatively high or hypertrophic.
