Magnetic Susceptibility and Dielectric Properties of Peat in Central Kalimantan, Indonesia

Peatlands dominate almost all regions of Borneo, yet its utilization has not been developed optimally. Any information in this field could be obtained using soil magnetization methods by determining the magnetic succeptibility in terms of magnetic susceptibility value that could describe the source and type of magnetic minerals which could describe the source and type of magnetic minerals. Moreover, the dielectric properties of peat soil were also investigated to determine the level of water content by using the dielectric constant value. Samples was taken at six different locations along Pulang pisau to Berengbengkel. Magnetic susceptibility mass value at these locations ranged between -0.0009 - 0.712 (x10(-6) m(3)/Kg). Based on the average magnetic susceptibility value, samples that were taken from T1, T3 and T5 belonged to the type of paramagnetic mineral, while samples which were taken from T2, T4 and T6 belonged to the group of diamagnetic mineral. The low value of magnetic susceptibility of peat was probably derived from the pedogenic process. The average value of peat soil in six locations has a large dielectric constant value that is 28.2 which indicated that there was considerable moisture content due to the hydrophilic nature of peatland which means that the ability of peat in water binding is considerably high.
