The various type of microalgae in lentic habitats

Abstract

Abstract Microalgae are unicellular algae living in freshwater. Algae were carbon fillers and biomass generators, so they have an important function to balance the environment. Lentic habitats can change rapidly, especially the existence of various activities such as sedimentation, pollution of various pollutants originating from domestic and industrial activities. This research aims to identify various types of microalgae in lentic habitats. Sampling was conducted at four-month intervals from April to June 2019. This zone divided into ponds and pools because it mostly used a water supply around the lentic area. The population in this research was microalgae in lentic habitats. From the results of the study that lentic habitats were found 4 divisions such Cyanophyta, Chlorophyta, Euglenophyta and Baccilariophyta, such Chlorella sp, Gloecapsa sp, Oscillatoria sp, Scenedesmus sp, Oedogonium sp, Microspora sp, Coleochaete sp, Closterium sp, Cymbella sp, Navicula sp, Pinnularia sp, Synedra sp, Euglena sp, Phacus sp, Trachelomonas sp. The microalgae were found on lentic habitat very affect by physical factors such as temperature, pH, and light intensity
