CO2 MEASUREMENT IN PALM OIL PLANT IN PEATLAND

Peatlands are one of the contributors to greenhouse gas emissions because it is estimated that carbon stock stored in them around 528 Giga tons (Gt) or equivalent 75% total (C) atmosphere, so if peat oxidized will cause be released into air. The conversion forest land agricultural can causes, including activity making drainage channels. construction channels causes a decrease water table volume under aerobic conditions increases while increasing microorganisms decomposing peat. Peat decomposition and root respiration contribute emissions. This study aims determine CO2 concentration several oil palm roots. measurement by survey method on plantations, using IRGA (Infra Red Gas Analyzer). Measurements carried out once per month from January May 2020 for 3 minutes. point observation was determined 2 factors with treatments replications. Factor 1 area accumulation midrib pieces other litter (B1) factor road tree (B2). While were (A1) natural roots, (A2) roots cut when measurements going taken (A3) permanently restricted. results highest average changes 0 minutes treatment B1A3 (140.4 ppm), February B2A3 (103.9 March (124.6 ppm) April (143.8 (110.7 ppm). Meanwhile, lowest B1A1 (71.5 (25.7 (40.2 B2A1 (30.6 (43.2 From results, concluded its B1A3, namely cutting permanent blocks, reduced both Blocks B1 B2.
