Struktur Komunitas Diatom Epipelik Di Zona Intertidal Perairan Mengkapan, Kecamatan Sungai Apit, Kabupaten Siak

ABSTRACT
This research was conducted in December 2020 in Mengkapan Waters, Sungai Apit
District, Siak Regency. The aims of this research was to analyze the composition,
abundance, diversity index, uniformity index, and dominance index of epipelic diatom
species in the intertidal zone. The method used is a survey method and the determination of
the sampling location by purposive sampling based on anthropogenic activities around the
waters. The water quality measured in this study were brightness, temperature, current
velocity, salinity, pH, nitrate, and phosphate. Based on the research results, there are 19
species epipelic diatoms found in Mengkapan Waters, namely Coscinodiscus sp., Navicula
sp., Gyrosigma sp., Thalassiosira sp., Pleurosigma sp., Synedra sp., Pinnularia sp.,
Surirella sp., Nitzchia sp., Triceratium sp., Melosira sp., Skeletonema sp., Stephanodiscus
sp., Oscillatoria sp., Cocconeis sp., Epithemia sp., Diadesmis sp., Cymbella sp., and
Amphipleura sp. The average value of abundance ranged from 29,245.37 – 35,744.33
ind/cm2, the diversity index value ranged from 2.5909 to 2.8014, the uniformity index value
ranged from 0.6736 – 0.7755, and the dominance index ranged from 0.1684 - 0.2064. Based
on one-way Anova test, concluded that abundance of epipelic diatoms between each stations
weren’t significant.
Keywords: Epipelic Diatom, Intertidal Zone, Mengkapan Waters.
