Abstract
Anthropogenic activities around the waters of Tanjung Api-Api, such as plantations, settlements and port activities, will result in changes to the marine environment. Excessive use of an area can result in loss of resources. This study aimed to analyze the abundance of macrobenthos around Tanjung Api-Api waters using the Principal Component Analysis (PCA) approach. The results show that the water quality parameters around Tanjung Api-Api waters are generally classified as moderate to heavily polluted, but they are still considered to be suitable for the macrobenthos growth. This is indicated by the temperature range of 26.0-33.06°C, the dissolved oxygen values between 6.45 and 9.81 ppm, the pH values from 6.59 to 7.29 and the salinity ranging between 12-18 ppt. Moreover, the sediment texture was found to be dominated by a clay substrate, while the macrobenthos abundance ranged between 1 and 8 ind m-2 , the diversity index ranged from 0.20 to 1.33, the equitability index ranged from 0.41 to 1 and the dominance index ranged from 0.28 to 0.85. Furthermore, the first group formed on the negative F1 axis showed that stations 2 and 9 were characterized by the variables of dominance and abundance, where the dominant class was Bivalvia, with 42%. Based on the PCA, the water quality parameters analyzed in Tanjung Api-Api waters were characterized by higher levels of salinity, pH and dissolved oxygen.
