Jenis Dan Kelimpahan Perifiton Pada Tumbuhan Teratai (Nymphaea Sp.) Di Waduk Bandar Kayangan Lembah Sari Kecamatan Rumbai Pesisir Kota Pekanbaru Provinsi Riau
ABSTRACT
Periphyton is a sessile microscopic organism that attach on certain substrate. A research aims to understand types and abundance of periphyton attached in the lotus leaves present in the Bandar Kayangan dam has been conducted in January to February 2019. There were 3 stations, around floating caged fish culture (Station 1), in the water closed to Tectona grandis plantations (Station 2) and in the recreational area (Station 3). Samplings were conducted 3 times, once/week. Lotus leaves were collected and periphytons were obtained through scraping upper and lower surface of the leaf (5×5 cm). Periphyton collected were preserved using Lugol 1% and then were identified. Result shown that there were 24 periphyton species present and they were belonged to 4 classes, namely Cynanophyceae (3 species), Chlorophyceae (5 species), Bacillariophycea (11 species), and Euglenophyceae (1 species). The abundance of the periphyton ranged from 1,425-2,378 cells/cm2, diversity index was 37,916-41,505 and dominancy index was 0,05923-0,0789. Based on data obtained, it can be concluded that the Bandar Kayangan dam water was fertile.
