Abstract :
This paper proposes a method for determining maturity levels of durian by using nondestructive vibration. The vibration is transferred directly through durian at a region between prickles located at the middle of durian. The measurement of frequency response from vibration of durian is performed by using laser Doppler techniques. The signal is processed for finding velocity of vibration, elastic constants and power spectral density. These data relates to %dry-weight
