PEMETAAN NILAI SUSEPTIBILITAS MAGNETIK TANAH DI SEKITAR KAMPUS UNIVERSITAS RIAU PEKANBARU

T hemappingof magnetic susceptibility v alue sofsoil around R iau University hasbeen done. T heamountof s oil taken f r om area r oundthe University about 250 mg f or each location. T henumber of s ample location sare 37 point sobtained f r om s ome Faculty at R iau University. T hemethodused for sample c ollection w as“ z ig- zag” method. T he 37 point location sof s amples s e lected base don thegrid method. Thetotal magnetic induction o f s olenoid w as measure dusing magnetic P asco P r obe Ps-2162, T he magneticparticles and non magneticpartic leswere separatedusing Neodibilium  Iron B oron  Magnet  (NeFeB). Theresults s howed that  the magnetic degree of s amples   variedin therangeof 0.04%  -4.36%. T he masssu s e ptibility values of thesamples alsovaried from 61,94 x 1 0-8m3/Kg - 2039,88 x 10-8m3/Kg. Mappingthemagnetic susceptibility v alues of s oil a r ound R iau University w asdone o f software usingthe “ surfer  11” . The highestvalues  of mass  suseptibility are obtained f r om E nginering F acultyandthe lowest v alues of masssu s e ptibility are located f r om E c onomics Faculty.
