Abstract:
The increase in the concentration of pollutants in the soil due to human activities is increasingly
worrying. Soil management requires soil pollution measurement technology due to heavy metal
contamination. Metal contaminants are indicators for the assessment of heavy metals in soil
through analysis of magnetic susceptibility measurement data. The samples used were soils from
a Settlement, a River Flow, and a Sand Mining area in Duri City, Bengkalis Regency. The
susceptibility measurement was carried out using a magnetization curve instrument based on an
RL integrator circuit with a frequency variation of 1, 10, and 100 Hz. The measurement results
show the effect of the given frequency, namely the greater the measurement frequency, the
smaller the susceptibility value. The three soil samples measured showed low and positive
paramagnetic susceptibility values. The Magnetization Curve Characterization Instrument can
be used and works well for the measurement of magnetic susceptibility values.
