ABSTRACT
This research is conducted to determine the differences between unripe, half-ripe and ripe oranges based on the structure of citrus fruits with different impedance values, real values, imaginary value, and phase angles values. The data obtained can be clustered using the Principal Component Analysis (PCA) multivariate statistical method. Taking impedance measurements using voltage from an excitation voltage source National Instrument I/O Card PCI 6221 is based on LabVIEW software and injected into alternating current using Platinum electrodes on oranges with frequency parameters of 10 Hz to 50 kHz. There are used three levels of ripeness of oranges, namely immature, half ripe, and ripe are measured with amplitude variations of 50 mV, 100 mV, and 250 mV respectively. The frequency increases, the value of the impedance decreases, the amplitude increases, and the impedance will also decrease. The highest impedance measurement results 25031.05 Ω for ripe oranges, 21703.78 Ω for half-ripe oranges and the smallest impedance value for immature oranges is 18008.01 Ω. This research uses pH and evalueates the level of sweetness to determine the ripeness level of citrus fruits. The value of impedance is be classified using (PCA). The results of the classification of oranges show significantly different. The value of orange reflects the sample projection determined by the principal components PC1 and both PC2. PC1 gives a variance of 44.7% and PC2 is 41.2%. The variance shown for PC1 and PC2 is 85.9%, which means that the characterization of the ripeness level of citrus using the PCA method is successful.
