Abstract
The existence of phytoplankton in aquatic environment are greatly affect
the aquatic life its self. Through photosynthesis, phytoplankton are responsible for
producing oxygen and nutrients especially for other marine organisms.
Furthermore phytoplankton can to be indicators of fertility and quality for an
aquatic ecosystem.The waters of Carocok Tarusan beach have congested
anthropogenic activities, like shipyard and shiping, tourism and domestic
activities. This of course greatly affects the existence of phytoplankton which is
very dependent on environmental conditions. This study aims to determine the
structure of the phytoplankton community and the relation with the characteristics
along with quality of the waters in Carocok Tarusan beach. Phytoplankton
samples were collected by using plankton net number 25 at three stations that
have been determined by purposive sampling method. The results showed that the
temperature values ranged from 29.3ºC-29.7ºC, salinity 27.7‰-31.3‰, brightness
1.8 m-3 m, pH 7, 0.3 m/s-0.6 m/s. There are 12 species from 3 classes found. The
most common species found were Navicula sp, Synedra ulna sp and Isthmia sp.
The average abundance of phytoplankton at each station is 57.86-92.58 Ind/L. The
results of the ANOVA test on the abundance of phytoplankton showed a
significant value of 0.108, which means the P value > 0.05, this indicates that
there is no significant difference in the abundance of phytoplankton between
stations. The value of the species diversity index (H') of phytoplankton has an
average value of 1.7436 - 2.0028. The Uniformity Index (E) has an average value
ranging from 0.1393 to 0.1464. Meanwhile,the phytoplankton dominance index
shows an average value of 0.2661 – 0.3191
