    Sail river is a tributary of the Siak river, located in Pekanbaru. Sail river is used by local people as a fishing ground as well as a place to dispose domestic waste that cause water pollution. The purpose of this research is to determine the water quality of Sail river in Pekanbaru according to the distribution and abundance of plankton organism using saprobic coefficient. Plankton was sampled by filtering 50L river water at 3 stations using a plankton net no.25 and preserved with 1% lugol. Water physical and chemical parameters at each station were also measured. During this study, the phytoplankton which was found consists of 4 classes: Bacillaryophyceae (13 spesies), Chlorophyceae (10 spesies), Euglenaphyceae (2 spesies) and Phyrophyceae (1 spesies). The zooplankton which was also found consists of only one class: Cilliata (3 spesies). Saprobic coefficient were ranged from -1 to +1. The abundance of the planktons were ranged from 6,72 ind/L to 96,6 ind/L. Saprobitas phases obtained during this study were β-mesosaprobic, α/β-mesosaprobic, β/α-mesosaprobic, and α-mesosaprobic. Based on those indexes Sail river was categorized into a river of moderate to heavy polluted. Content of pollutant based on saprobitas phases were grouped into organic + anorganic materials for moderate polluted and organic material for heavy polluted.
