Pengaruh Posisi Durian dalam Penentuan Kematangan secara Non Destruktip Menggunakan Gelombang Ultrasonik

Abstract

The study was conducted to assess the influence of durian 's position toward transmission properties of ultrasonic wave for determination of the fruit ripeness using non-destructii-e technique. Three ripe and unripe duria~u were used to assess transmittance wave that was passed the durian. The measurement was conducted at 3 peak and valley positions and it was repeated 20 times. The result showed that position durian 's inJluenccad the transmissions of ultrasonic wave. Mo mzJ a (attenuation) values can be used as indicator for durian ripeness. Ripe durian tends to have highera value than unripe durian.
