---

ABSTRACT
Periphyton is sessile microscopic organisms that attach on certain substrates. The aim of the study was to determine the types and abundance of periphyton on ceramic substrates in July-August 2022 on the Mandau River. The research method used is survey method. Sampling was carried out 3 times for 10 days. The substrate used is a ceramic substrate with a size (8x3) cm2. The number of ceramic substrates at each station was 40, 30 and 20 pieces respectively at station 1, station 2 and station 3. As a result, there were 25 types of periphyton belonging to 4 classes, namely Bacillariophyceae (14 species), Chlorophyceae (7 species), Cyanophyceae (3 species), and Dinophyceae (1 species). The average abundance of periphyton ranges from 19.754 – 40.574 cells/cm2. The results of water quality measurements showed that: brightness (28-35 cm), temperature (29-30ºC), current velocity (0,21-0,24 m/s), pH (4-5), dissolved oxygen (2,5- 3,1 mg/L), free carbon dioxide (18,81-20,17 mg/L), nitrate (0,0160-0,0260 mg/L) and phosphate (0,0467-0,0668 mg/L). Based on the concentration of nitrate, it is classified as oligotrophic, while based on the concentration of phosphate, it is classified as oligotrophic.
Keywords: Mandau River, periphyton, ceramic substrate, type and abundance
