According to a survey of Tidal Rice Development (P4S) from IPB between 1974 and 1978, there was only 22.6% peatland area in South Sumatera. The P4S surveys were done at semi detail intensity (1:50.000) and carried out with intensive ground observation. Peatland area in the same region was also mapped into Peat Hydrological Map (KHG) in 2017. According to KHG maps, the peatland area in the region should have been larger than what P4S has surveyed. The peatland nearly impossible to expand in a short time, on the contrary, it might decrease. Hence, this study was aimed to compare peatland area from both maps above as a basis for the improvement of peat data. Peatlands were compiled from the results of the P4S surveys in South Sumatera, among others Sugihan Kiri, Air Saleh, Delta Upang, Musi Banyuasin, Calikin Calik, Karang Agung and Muara Padang which were then mapped into KHG. Both were processed with Geographic Information System (GIS) procedures. The overlay results show that the size from 16 KHG area of peat in the study area is 445,676 Ha, meanwhile based on the results of the P4S soil mapping is 137,670 Ha. It shows that KHG peat is much larger than the results of The P4S soil mapping, which is absolutely clearly, indicates the inaccuracy in withdrawing the KHG area boundaries in this region.
