Abstract
ABSTRACT Plankton is one of important organism in aquatic ecosystems. Danau Hijau is one of the aquatic ecosystems found in Pangkalan Village. Research on the community plankton in Danau Hijau coal mine-lake former in Pangkalan village, District Kuantan Singingi, Riau aims to determine structure and composition and chemical characteristics of water in Danau Hijau Pangkalan. This research have been conducted from March until October 2018. The method of research is by using purposive sampling on five stations with three repetition. Samples plankton collected using net plankton no 25. The research found 29 species of plankton were identified from 18 families, 5 classes. The highest composition is Bacillariophyceae (8 family, 18 species). The highest density in station V and the lowest density in station IV. The diversity of plankton in these waters classified as the moderate (H’=0,91). Equitability index (E) of plankton in this ecosystem classified unevenness (E=0,06). The plankton which there is always found at very observation station is Cylindrotheca closterium, Closterium idiosporum and Nitzschia longissima. The plankton similarity indeks ranges from (IS=45,71-66,67). The pH conditions are acidic (pH=4-5). Kata kunci: Cylindrotheca closterium, Closterium idiosporum and Nitzschia longissima
