Abstract

Over time, Rupat Island has experienced very rapid development, marked by various activities such as plantations, agriculture, farming, and ecotourism activities which are growing rapidly. This study aims to determine the relationship between concentrations of nitrate, phosphate, and organic matter on the abundance of phytoplankton in Rupat Island waters. The results showed that the average nitrate concentration was relatively high, ranging from 0.0993-0.1618 mg/L and the average phosphate concentration was around 0.0951-0.1571 mg/L. Furthermore, the concentration of organic matter in water ranged from 27.555-35.234 mg/L. The lowest abundance of phytoplankton was found in the Station II area with an average abundance value of around 416.67 cells/L, while the highest average abundance was in the Station V area with an average value of 993.05 cells/L. The relationship between the content of nitrate, phosphate, and organic matter with the abundance of phytoplankton in the Rupat Island area was insignificant or weak with a coefficient of determination (R2) of 8%, 10.5% and 3.3%
