【 摘 要 】

Phytoplankton is a major producer in oceans which require the availability of nutrients, pH, temperature and light intensity in order to increase the productivity. This study aims to analyse the relationship between the primary productivity and the abundance of phytoplankton in Muara Kuala Raja Bireuen, Aceh. This study was conducted on May 2017. Location sampling have 3 station points. The measure of primary productivity was examined by a light-dark bottle oxygen method. The relationship between the primary productivity and the abundance of phytoplankton was analysed by using Principal Component Analysis (PCA). The results showed that the highest average of gross and net primary productivity were found at station 1 of 209,12 mgC/m 3/h and 172,00 mgC/m 3/h. The highest abundance of phytoplankton was found at station 1 of 11477,76 ind/l. The result of PCA showed that each of the parameter spread between the two axes indicates the data diversity value. The data diversity value on the 1-axis was 37% and the 2-axis was 59%, so the total of data diversity between 1- axis and 2-axis was 96%. Based on the PCA analysis, it can be concluded that primary productivity has a strong relationship with the abundance of phytoplankton.
