PERBANDINGAN KADAR C-ORGANIK PADA TANAH GAMBUT TERBAKAR DAN TIDAK TERBAKAR DI LAHAN ARBORETUM UNIVERSITAS SRIWIJAYA
Peat soil is soil that contains a high amount of organic matter derived from plants that have decomposed under anaerobic conditions. Dry peatlands are highly susceptible to fires. Fires in peat soil cause a significant amount of organic matter to be lost as ash, resulting in lower levels of organic carbon remaining in the soil. This study aims to determine the comparison of organic carbon content in burned and unburned peat soils at the Sriwijaya University Arboretum. The study was conducted using a survey method with a 1:4000 scale map at six observation points. This study was carried out on the peatland of the Sriwijaya University Arboretum, North Indralaya Subdistrict, Ogan Ilir Regency, South Sumatra Province, from October to December 2025. The parameter analyzed in this study was soil organic carbon using the Loss on Ignition (LOI) method. The results of this study indicate that there is a difference in organic carbon values between burned and unburned peatland. Soil organic carbon in burned peat tended to be lower than in unburned peat, ranging from 20.46% to 32.51%. Meanwhile, soil organic carbon in unburned peat ranged from 28.86% to a maximum of 45.17% in sample T5. Keywords: Loss on Ignition, Organic carbon, Peat.
