Dielectric properties of carbon from cassava starch synthesized from hydrothermal process

Carbon has been synthesized from biomass materials ie cassava starch through a hydrothermal process has potential as dielectric material. The carbon synthesized from cassava starch through a hydrothermal process is then made into pellets, then tested capacitance value using a HIOKI 3522-50 LCR HiTESTER using conductive ITO glass as the electrode during measurement. This study aims to determine the dielectric properties of carbon synthesis through measurement on the value of capacitance. Through the measurement of capacitance values are used to determine the value of the dielectric constant. Measurements were performed with the two aspects, namely the measurement of capacitance with temperature and capacitance measurement of the frequency. The test results indicate a change in the capacitance value both to changes in temperature and frequency. While the value of the dielectric constant also shows the dependence on temperature and frequency. Based on the measurement of dielectric constant value of the carbon that was synthesized shows the level of ability of carbon material in terms of storing a charge. The synthesized carbon is a potential material as a dielectric material which can be applied in the manufacture of capacitors.
