Peatlands play a crucial role in Indonesia's agricultural sector and their use is often linked to environmental concerns, such as being a source of CO2 emissions. This study analyses the relationship between CO2 flux, ground water level, and soil water content in oil palm plantations in the tropical peat ecosystems of Pangkalan Pisang District, Riau Province. The research was conducted from October 2023 to March 2024, measuring CO2 flux in three plots inside oil palm plantations: Bare plots, N. biserrata plots, and plots under oil palm trees. CO2 flux measurements were carried out using a closed chamber method and an Infrared Gas Analyzer (IRGA); additional factors such as groundwater level and soil water content were also measured simultaneously with CO2 flux. The results showed that the average CO2 flux measured was 6,25±3,68 g m-2 d-1 in Bare plot, 8,25±4,30 g m-2 d1 in N. biserrata, and 9.80±5,75 g m-2 d-1 near oil palm trees. The results indicate that, except for bare plots, there is no significant correlation between Ground Water Level (GWL) and Soil Water Content (SWC) with CO₂ flux.
