Ground Penetrating Radar Mapping of Peat Depth at Burnai-Sibumbung Rivers Peatland Hydrological Unit Ogan Komering Ilir Regency

Ground Penetrating Radar (GPR) is one of the geophysical methods, which utilize electromagnetic (EM) wave transmitted the wave through an antenna and recorded by a receiver antenna. The result is a subsurface profile, called a radargram than inform the location and depth of the object or layers. To produce medium to high scale of peat depth, low-frequency Ground Penetrating Radar data acquisition was conducted at Burnai-Sibumbung River Peatland Hydrological Unit, Ogan Komering Ilir Regency. Result of processing GPR data shows with the distinct boundary between peat and clay layer. At the same time, GPR peat data acquisitions area calibrated by manual core measurement and have found velocity radar wave in peat is 0,0361 m/ns. The Result of processing all line GPR data, peat depth at this peatlands area vary from 1.0 to 9,7 meters, the lower area is the west and deeper to the northeast.
