Abstract

Indonesian Government Regulation No. 71/2014 requires all parties to maintain the groundwater level less than 40 cm below the ground level to prevent land fires in peatlands. This regulation is quite burdensome as it will be tough to do during the dry season. The research results on peat, which has a hemic maturity level, show that the soil water content is still in the range of 200% at a distance of 50 cm above the groundwater level. The purpose of this study was to study whether the same thing would happen to peatlands with different humification levels and water table depth. Research has carried out using survey and monitoring methods on the peatlands of PT. Mendahara Agrojaya Industri, located in Lagan Tengah village, Geragai sub-district, Tanjung Jabung Timur Regency, for six months to achieve this objective. Data collected includes peat depth determined by drilling using a peat drill. Peat maturity is determined using the van Post method; groundwater depth carried out using steel tape. The soil water content determines the gravimetric method. The C-organic content was determined using the loss on ignition method. The results showed that 1) there was a difference in soil water content between the water level depth (40 cm, 50 cm, and 60 cm) below the peat surface and the different humification levels of peat (sapric and hemic), 2) the farther from the groundwater level, the faster the peat burns, and 3) peat fires begin to occur at a groundwater level of 50 cm
