Dryness Level Measurement of Coconut Shell Charcoal Briquettes using Plate-shaped Electrodes

Briquette dryness level is a benchmark for coconut shell charcoal briquette quality. In this study, the measurement of briquette dryness was studied by measuring the resistance of the briquette using plates attached to the sides of the briquette. Performance of copper plate electrodes was compared with the performance of electrodes made of PCB pieces. Briquette dryness is divided into 3 groups. They are wet, half-dry, and dry. From the measurement results, it was found that the measurement of briquette resistance with PCB plate electrodes was more stable than with copper plate electrodes. Briquettes are declared dry if they have a high resistance or low conductivity.
