Abstract

The macrozoobenthic community structure can be used as a bioindicator to determine water pollution. The macrozoobenthic community structure consists of species, abundance, diversity index (H '), dominance index (C) and species uniformity index (E). This research was conducted in July 2020 in the waters of the North Coast of Bengkalis Island. Water parameters measured include temperature, salinity and pH. In this study, it was divided into 3 stations, namely in Selat Baru Village (station 1), Jangkang Village (station 2) and Teluk Pambang Village (station 3). The results found that as many as 34 species from 4 classes of macrozoobenthos, namely Gastropods, Malacostraca, Bivalvia, and Merostomata. Gastropod class macrozoobenthos such as Volema pyrum, Littoraria scabra, Nassarius vibra, Drupella margariticola, Pirenella cingulata, and Nerita costata; from the Malacostraca class such as Uca dussumieri, Ocypode kuhlii, Clibanarius longitarsus, and Litopenaeus cetiferus; from the Bivalvia class such as Glauconome virens, Polymesoda expansa and Dinocardium robustum and from the Merostomata class such as Carcinoscorpius ratundicauda. The macrozoobenthic abundance values ​​from the three stations ranged from 0.01 to 1.29 Ind/m2, the diversity index value (H') ranged from 2.5589 to 2.8516, the dominance index value ranged from 0.2503 - 0.3312 and the uniformity index (E ) ranges from 0.6397 to 0.6838. Water quality parameters are as follows: temperature is 29-31°C, salinity ranges from 23-28 ppt, and pH ranges from 7.5-7.9. Sediment organic matter ranged from 6.88 to 11.26% and TSS ranged from 474-542 mg/L with the dominant sediment type at the three stations, namely sandy mud.

Abstract

Organic matter has an important role in marine ecology and it can be used as an indicator of water fertility. The content of organic matter in the waters in a certain amount can be useful for aquatic biota, but if it exceeds the acceptable threshold for the environment and organisms, it can cause disturbances. The content of organic matter in the waters will increase due to waste from households, agriculture, industry, and organic waste from land that is carried into the waters. Various community and industrial activities both on land and waters in the South of Bengkalis Island can provide input of organic matter in the waters. The method used in this research is a survey method that is carried out directly in the field to collect data and samples which are then analyzed. This study aims to determine the content of organic matter in water and sediment and analyze their possible relationship. The results showed that the organic matter content of the water ranged from 34.36 – 35.96 mg/L and the organic matter content of the sediment ranged from 4.78 – 13.78%. The content of organic matter in the waters has not exceeded the quality standard threshold. The results of a simple linear regression test showed a positive relationship with an R2 value of 0.712, which means that the relationship between the organic matters content of water and sediment is quite strong (71.2%). The types of sediment in the southern waters of Bengkalis Island are the mud type.
