The Ground Penetrating Radar (GPR) method commonly known as Georadar, a nondestructive geophysical method that uses electromagnetic waves. This method is widely used to determine conditions under the surface such as mapping structures and subsurface lithology or buried objects. In this study, the GPR measurement using Geoscanners AKULA A9000 + Antenna GCB3070 is conducted to detect the presence or capacity of a septic tank. The GPR data were initially processed using matGPR based on MATLAB. GPR data on each measuring line is processed first, a series of filters and gaining have been conducted such as Adjust Signal Position, Remove DC, Dewow, Inverse Amplitude Decay, Remove Global Background, Karhunen-Loeve Filter, then time to depth conversion with adjusted parameters. From the result of parameter analysis in processing data, found that the GPR data can be interpreted which show the underground septic tank in the study area with the presence of diffraction signatures.
