PERUBAHAN KEKAKUAN DINAMIS KAYU SETELAH PENGUJIAN KEAWETAN ALAMI KAYU NANGKA DAN MANGIUM
ABSTRACT: The aim of this
study was to evaluate dynamic modulus of elasticity (MOEdyn) of woods after
tested those natural durability. Field tests by grave yard test were applied to
prove the natural durability of jackfruit and mangium woods in ground contact.
The method of non-destructive testing based on ultrasonic wave propagation was
carried out to define ultrasonic velocity than that used for evaluating MOEdyn.
The result showed that ultrasonic velocity of jackfruit and mangium woods
decreased 3% and 0.5%, respectively after field test. There was a significant
difference of MOEdyn value between before and after natural durability testings.
