In the development of various contemporary technological applications, the electrical properties of materials are crucial. This study analyzed activated carbon made from cocoa pod husk (PCC) for its electrical permittivity and conductivity. Parallel plates measuring 8 cm x 8 cm with a distance between plates of 0.5 cm were used for both measurements. The PCC activated carbon served as a dielectric between the plates. To measure the conductivity of the material, a DC voltage source was connected to the material at 0.5 volt intervals within the range of 3 to 5 volts. The electrical conductivity obtained was 5.5 × 10–5 S/m, indicating that the PCC activated carbon is a semiconductor. In addition, electrical permittivity measurements were also carried out using an AC voltage source with a frequency range of 10,000 Hz to 100,000 Hz. The results showed that increasing frequency was negatively correlated with decreasing permittivity values. The permittivity value reached 65.52 at low frequency (10,000 Hz), but decreased to 16.15 at high frequency (100,000 Hz). This decrease indicates the high frequency dielectric dispersion of KBK activated carbon.Keywords: Paper Format, JMT, jurnal
