Abstract

Tropical peatlands in Indonesia are very large, covering an area of about 13.4-14.9 million hectares. Kubu Raya District, West Kalimantan, is known to have significant natural resources and large regions of peatland. This research aims to estimate the thickness and volume of peat soil in the Rasau Jaya and Sungai Raya sub-districts of Kubu Raya Regency. This research uses the Ground Penetrating Radar (GPR) method, using the Plug-In Cobra GPR SE70 tool with a frequency of 80 MHz. This research applies 23 tracks and validation by three drill points, consisting of nine tracks in Sungai Raya District and 14 tracks in Rasau Jaya District. GPR data is processed through several processes: static correction, dewow, Butterworth bandpass, background removal, gain, subtracting average, and horizon picking. The results showed that the subsurface electromagnetic wave propagation speed at the research location was 0.026 m/ns, having a peat thickness of 0.8-4.2m. The deepest peat layer is in the east, having a thickness of 3.8-4.2m, while the shallowest peat layer is in the west, having a thickness of 0.8-1.1m. The results also show that the volume of peat in the research location is 4.8×107 m3
