Abstract

The use of peatlands in the future will receive a stronger impetus and is likely to become more widespread. Electrical properties can be used as indicators to measure soil conditions. One of the methods developed in agricultural systems to obtain soil condition information is by measuring its electrical and dielectric conductivity properties. The types of peat maturity are divided into sapric peat (ripe peat), hemic peat (half-ripe peat), and fibric peat (unripe peat). Sampling of peat soil in different locations, namely West Labuh Baru Village, Payung Sekaki District (fibric peat), Rimbo Panjang Village, Tambang District (saprik peat), and Kubang Jaya Village, Siak Hulu District (hemic peat). This study aims to determine the electrical and dielectric conductivity of peat maturity and depth at 0 cm-50 cm with variations in moisture content from 0-35% and a frequency of 100 Hz-10 Mhz. The results of this study indicate that the conductivity value will increase when the peat maturity level is lower as the frequency increases. Based on the depth, the conductivity value will be higher as the depth of the peat increases. The dielectric value of peat will increase when the maturity level of the peat is lower and decrease when the frequency is high. Based on the depth, the conductivity value will be higher as the depth of the peat increases. Fibric peat has the highest conductivity and dielectric values.
