Abstract

Periphyton Abundance Characteristics of Seagrass Type Enhalus acoroides in Malahing Waters of Bontang City.(suvervised by Lily Inderia Sari and Widya Kusumaningrum) The research activities out around from March-May 2019. Periphyton sampling was sampled randomly selected at 4 observation station which are then indentified at the Fpik Unmul Water Quality Laboratory. The research result of the study found 21 species consisting of 10 classes, ther are Bacillariophyceae, Cyanophyceae, Zygnematophyceae, Oligomenphorea, ulvophyceae, Tubulinea, Dinophyceae, Conjugatophyceae, Trebouxiophyceae and Euglenoideide. The periphyton composition that dominated was from the Bacillariophyceae class, namely Nitzschia sigma with a percentage of 8,31 % and Nitzschia filiformis with a percentage of 8,28 %. Periphyton diversity index value of 1,514 is medium density. The Uniformity Index of 0,837 is relatively the same. The Dominance Index value of 0,183 is classified as not occurring species dominance.
