Abstract

The geoelectrical data processing has been carried out using the Schlumberger method using the damped least squares
inversion program with the geoelectric method to determine the underground structure which is very suitable for cases in a
small scope, for example around the UNILA Football Field area. The data used is the result of measurements made last
year with the Naniura NRD 300 HF tool. By processing the data using the MATLAB software, the resistivity curve and the
actual depth will be obtained which will then be compared with the results of the IPI2WIN software processing. The purpose
of this processing is to prove that this method is more effective where the dominant RMS error value is smaller because the
iterations that have been carried out make the results quite valid in describing the subsoil layer. With this processing, it is
hoped that this method can continue to be developed in further analysis in determining the subsoil layer
