Abstract

Abstract. The aims of the present study was to evaluate community structure and biomass of phytoplankton based on the depth stratification in the waters of Lake Laut Tawar. Sampling was conducted during March and April 2010. The results showed that 43 species of phytoplankton belonging to five classes were found in Lake Laut tawar. The most common class was Chlorophyceae with 20 genera, followed by Bacillariophyceae (diatoms) by 9 genera, Cyanophyceae (10 genera), Dinophyceae (2 genera), and Euglenophyceae (2 genera). The highest species composition was found at II with 15 m depth (24 genera), while the highest abundance of phytoplankton was occured at station with 10 depth (155600 cells/l), while the lowest abundance was obtained at 15 depth (12745 cells/l). Overall the phytoplankton population in Lake Laut Tawar was dominated by Bacillarophyceae. In addition, the diversity index of phytoplankton was in moderate level (2.34), while the evenness index was ranged from 0.43 to 0.87, indicate the distribution of the individuals of each species was varied, however there was no predominant species detected.Keywords. Phytoplankton, structure community, Laut Tawar Lake.

Abstract

Deli River has been designated as a national river that has made a major contribution to the economic growth and development in the Medan city of North Sumatra. However, rapid urbanization and human population growth have caused degradation of the quality of Deli River due to increasing pollution. This study aims to analyze the level of pollution of the Deli River using the Pollution Index (PI) and CCME Water Quality Index (WQI) methods with reference to Government Regulation Number 22 of 2021. The research location was divided into 4 stations from upstream to downstream of the Deli River. Based on PI method, stations 1, 2, and 3 were classified as lightly polluted, while station 4 experienced moderate pollution. The results were different when using the CCME WQI method, which showed that stations 1, 2, and 3 were classified as having fairly good waters, while station 4 was poor waters. Water quality analysis was carried out on 13 parameters, 5 of which exceeded the river water quality standard threshold, namely BOD, ammonia, Pb, Zn, and Cd.Keywords:Deli riverRiver pollutionWater qualityPollution Index (IP)CCME WQI
