PENDUGAAN KEKAKUAN KAYU BORNEO DENGAN METODE GELOMBANG ULTRASONIK
Abstract: Borneo wood is a
name for various species commercial wood. The aimed of this study are measured
stifness (MOE) of borneo wood using non destructive method i.e. ultrasonic
wave. Fiveteen beam sample were produced from borneo wood about 8 cm thick and
12 cm width with 400 cm, 250 cm and 150 cm length. Beam with 250 cm and 150 cm
length produced from beam with 400 cm length after stifness test have done
using ultrasonic (dynamic test) and UTM (static test). Result showed that
dynamic MOE of borneo wood for 400 cm, 250 cm and 150 cm length, are 19.10
G.Pa, 18.48 G.Pa and 15.90 G.Pa, respectively. Wood about 400 cm and 150 cm
length were different significantly. Result also showed that dynamic MOE of
borneo wood 30% higher than static MOE at vertical position test for beam with
400 cm length and 20% higher for horisontal position at the same testing
method.
