Composition and distribution of phytoplankton in Jatigede reservoir

Abstract

The purpose of this study is to describe the distribution of phytoplankton in the form of maps both vertically and horizontally in Jatigede Reservoir. The study was conducted from August 2020 to March 2021. The method used in research is a survey method with a purposive sampling sampling technique. The highest abundance is in station 1 (reservoir inlet) and the lowest abundance is in station 6 (reservoir outlet), each on the surface, depth of half compensation and compensation. Phylum Pyrrophyta and class Dinophyceae make up the composition of the highest abundance of phytoplankton. Based on the order, Stephanodiscales with the genus Cyclotella became the highest constituents of the composition of abundance. The distribution of phytoplankton is evenly distributed at every station, except the phylum Chrysophyta which is only found at station 3.
