PENGUKURAN TINGKAT KEMATANGAN BUAH JERUK DENGAN METODE IMPEDANSI

Abstract

Citrus fruit is a citrus fruit that is very popular with the world community. That's because oranges have vitamins that are good for the human body. This research was conducted to determine the differences between unripe, half-ripe and ripe oranges based on the structure of citrus fruits with different impedance values, real, imaginary, and phase angles. Taking impedance measurements using voltage from an excitation voltage source National Instrument I/O Card PCI 6221 based on LabVIEW software and injected into alternating current using platinum electrodes to oranges with frequency parameters of 10 Hz to 50 kHz. The measurement uses three levels of orange ripeness, namely immature, half ripe, and ripe. The more ripe the fruit, the impedance value will increase.
