Abstract
Agarwood is a non-timber forest product with high economic value. This incense wood is produced in the living stem of Aquilaria tree species after exposure to several stress factors and is not profoundly visible. Traditionally, agarwood hunters or collectors predict the existence of agarwood in the tree by relying on their visual assessment and experience, which may not be accurate at all times. To overcome this uncertainty, new technologies such as the nondestructive testing (NDT) technology are more reliable at providing valuable information for managing an agarwood plantation. In this study, an acoustic-based NDT has been applied on wounded and inoculated Aquilaria trees from which a reduction in sound velocity has been recorded. When coupled with PiCUS® sonic tomograph device, the tomogram results displayed progressing stages of decays consistent with that caused by fungal attack. The technology has been successful in detecting the existence of the agarwood in the target tree and can be improved for estimating the quantity and quality of agarwood in live trees periodically, before the final harvesting.
