Abstract

This study examines the water quality of the Senepis Peat Forest in Riau, Indonesia, by analyzing key water quality parameters, including pH, dissolved oxygen (DO), carbon dioxide (CO₂), biochemical oxygen demand (BOD₅), and chemical oxygen demand (COD). Data collected in 2017 and 2018 show significant variations in these parameters across different locations. pH values ranged from 4.9 to 7.7 in 2017 and from 5.1 to 7.7 in 2018, with lower pH in upstream areas, reflecting the influence of organic acids from decomposing plant matter. DO levels varied from 2.7 mg/L to 17.3 mg/L in 2017 and from 1.2 mg/L to 22.7 mg/L in 2018, with lower concentrations found in rainwater and polluted sites. CO₂ concentrations ranged from 19.98 mg/L to 191.44 mg/L in 2017, reflecting significant organic matter decomposition in peatlands. BOD₅ levels varied from 2.18 mg/L in rainwater to 14.59 mg/L in Nyamuk Hilir River in 2018, indicating high oxygen demand due to organic pollution. COD values ranged from 6.8 mg/L in rainwater to 114.4 mg/L in Teluk Dalam Hilir in 2017, signaling substantial organic pollution. These findings provide insights into the water quality dynamics in the Senepis Peat Forest, highlighting the effects of natural and anthropogenic factors on the aquatic ecosystem.
