PEMETAAN NILAI SUSEPTIBILITAS MAGNETIK TANAH DI SEKITAR KAMPUS UNIVERSITAS RIAU PEKANBARU

Abstract

The mapping of magnetic suseptibility values of soil around Riau University has been done. The amount of soil taken from area around the University about 250 mg for each location. The number of sample locations are 37 points obtained from some Faculty at Riau University. The method used for sample collection was “ zig-zag”method. The 37 point locations of samples selected based on the grid method. The total magnetic induction of solenoid was measured using magnetic Pasco Probe Ps-2162, The magnetic particles and non magnetic particles were separated using Neodibilium Iron Boron Magnet (NeFeB). The results showed that the magnetic degree of samples varied in the range of 0.04% - 4.36%. The mass suseptibility values of the samples also varied from 61,94 x 10 -8 m3/Kg - 2039,88 x 10 -8 m3/Kg. Mapping the magnetic suseptibility values of soil around Riau University was done of software using the “ surfer 11” . The highest values of mass suseptibility are obtained from Enginering Faculty and the lowest values of mass suseptibility are located from Economics Faculty.
