| Summary: | The electrical potential on the Earth's surface can be studied using methods from
the field of geophysics. One such method is the self-potential method, which aims
to obtain information related to natural static potential caused by subsurface
anomalies. The steps in this method start with electrode construction, field data
acquisition, elevation and position correction, and proceed to inverse modeling,
which results in a comparison between field data and data calculated using the
Levenberg-Marquardt method. The results from synthetic data have been illustrated
in graphical form. The field data obtained is then processed in the order mentioned
earlier. Based on the research, the distribution of electrical potential values obtained
from the study area ranges from 47mV to 240.72mV. The anomaly in the study area
is a vertical cylinder located at a depth of 14 meters, with a shape factor of 0.2432,
an angle of 91.48°, and a dipole moment of -58.5677.
