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. This shows that the waters north of Bengkalis Island are classified as being polluted.

Abstract

The entry of nutrients (nitrate, phosphate and silicate) from land-based anthropogenic activities (industry, agriculture and household waste) through rivers can potentially cause changes in water quality and will affect fertility and aquatic organisms such as phytoplankton. These three nutrients play an important role in the living tissue cells of living organisms and in the photosynthesis process. This study aims to analyze the effect of nitrate, phosphate and silicate content on the plankton abundance in the estuary of the Batang Arau River, Padang, West Sumatra. The method used is a survey method, the determination of the sampling station is done by purposive sampling, data were analysed by Excel and SPSS Software. Based on the results of laboratory analysis, the nitrate content ranged from 0,117 to 0,485 mg/l, phosphate content from 0,239 to 0,704 mg/l, and silicate content from 0,031 to 0,685 mg/l. Planktonic diatom abundance in the estuary of the Batang Arau River ranges from 194 to 750 ind/l. The results of the statistical analysis of the effect of nitrate, phosphate and silicate with an abundance of diatoms are expressed by the equation Y = 743,019 - 481,828Nitrate - 199,552Phosphate - 172,971Silicate. This equation explains that the effect of nitrate, phosphate and silicate content on diatom abundance has an inverse or negative relationship, where nitrate, phosphate and silicate levels increase, the diatom abundance will decrease. The difference of content and the relationship between parameters analyzed in this research are discussed.
