ABSTRACT
The existence of phytoplankton in the waters can provide information about water quality, while nitrates and phosphates affecting the availability of phytoplankton for growth and energy transfer. This research aims to know phytoplankton abundance and kinds of phytoplankton, find out the levels of nitrates and phosphates in the water and its connection with the abundance of phytoplankton, and find out saprobics index water. The research was conducted in May – June 2016. Material used in research was sample of phytoplankton and water samples. Methods used field survey with purposive technique sampling. The activity of sampling done in three times in 3 different stasions. Collection of phytoplankton sample using plankton net and active sampling method. Phytoplankton samples preserved using 2-3 drops lugol's iodine before identified in the laboratory. Water samples to be tested it is nitrate and phosphate contents in laboratory scale. Data analysis research was done using Microsoft Excel 2013. This research shows the content of nitrate is about 0.069 to 0.088 mg/l. Nitrate content is optimal for growth of phytoplankton and phosphate is about 0.004 to 0.006 mg/l. Classified quite high but still can be tolerated by the phytoplankton. Phytoplankton abundance ranges from 1774 - 3657 ind/l. The correlation coefficient (r) between nitrate and phytoplankton abundance is 0,98 then between phosphate and phytoplankton abundance is 0,902. The result means both of them have a strong correlation. SI values from 1,28 to 1,43, and TSI value from 1,64 to 2,66 this show that water quality in Pari Island Thousand Island is categorized into oligosaprobic which is lightly polluted to uncontaminated.
