Abstract
This study was conducted in September 2022 in Kasiak Island Water, Pariaman City, West Sumatra Province. The purpose of this study was to analyze the community structure of phytoplankton, zooplankton, and the relationship between the abundance of phytoplankton and zooplankton in the waters of Kasiak Island. The method used is survey method. Plankton sampling was carried out at four stations with three sampling points. Plankton samples were obtained by filtering 100 L of surface water to 125 ml, then analyzed in the laboratory. The results obtained were 21 species of phytoplankton and 11 species of zooplankton. The average abundance of phytoplankton in the morning ranged from 923,15–2.400,19 ind/L and during the day ranged from 1.200,09–2.492,50 ind/L. The average abundance of zooplankton in the waters of Pulau Kasiak in the morning ranged from 369,26–1.200,09 ind/L and during during the day ranged from between 369,26–1.384,72 ind/L. Phytoplankton biological indices such as the diversity index (H') in the morning ranged from 0,6096–2,3075 and during the day ranged from 1,3894–2,0129, the equitability index (E) in the morning ranged from 0,4844–0,9851 and during the day ranged from 0,9060–0,9624, and the dominance index (D) in the morning ranged from 0,2181–0,6617 and during the day ranged from 0,2833–0,4248. While zooplankton biological indices such as the diversity index (H') in the morning ranged from 0,2704–0,8617 and during the day ranged from 0,3333–1,1950, th equitability index (E) in the morning ranged from 0,2704–0,6667 and during the day ranged from 0,3333–0,6667, and the dominance index (D) in the morning ranged from 0,6111–0,8750 and during the day ranged from 0,5278–0,8333. The relationship between the abundance of phytoplankton and zooplankton in the morning and during the day has a moderate (positive) relationship. The regression equation in the morning is Y = 0,1356x + 434,53 and during the day it is Y = 0,1845x + 362,01.
