Abstract

This research discusses the principles of measuring the electrical impedance of a solution using parallel plate probe. The method used is by injecting an AC-current in the solution within the frequency range of 1Hz - 1MHz. The electrical impedance value plotted as a function of frequency. The results of the experiment showed that the electrical impedance of a solution could be measured correctly by using this method. The surface area of the probe, the distance between the probe, and the frequency of the injected AC-current, giving the measured impedance value changes significantly. This method also proved to be used to identify the value of the concentration of the sugar solution with relatively good accuracy. The experiment results demonstrate conformity with the existing theory

Abstract

Electrical impedance value analysis on frozen tilapia flesh aims to analyze non-destructive method of electrical impedance to distinguish between fresh and frozen tilapia flesh. The measurements were carried out to measure electrical impedance fresh tilapia flesh and frozen tilapia flesh for 1-5 days at 10 Hz - 200 kHz frequency using needle electrode. The result shows that the impedance value characteristics of the fresh tilapia flesh is higher than frozen tilapia flesh. The longer strored in the freezer is directly reversed with the value of electrical impedance. The observation of electrical impedance on quality of tilapia flesh preferable observed at a frequency of 1 kHz - 100 kHz.
