| Summary: | This study was to determine the strength properties of oil palm lumber with
two variables is treatments (acetone, ethanol, & control) and portions (bottom
outer, bottom inner, middle outer, & middle inner) of the tree. The treatment
is selected to use which method is suitable and effective to be used in the
drying process to increase the strength properties of oil palm lumber (OPL).
The sample size was 20mmx20mmx300mm and tested using bending testing
method to determine the strength properties. The test was conducted in
accordance to ASTM 04761-13:2012. Showed, the Modulus of Elasticity
(MOE), Modulus of Rupture (MOR) and density of OPL are discovered.
Result show, treatment by acetone is higher than other treatment with the
mean value of MOE is 539.50MPa and mean value of MOR is 5.12MPa.
While the result studied on different portions showed the bottom outer part is
highest and the lowest is middle inner· part. The suitable treatment that can
be applied in drying process for OPL is with acetone and the suitable portion
that can use is the outer part, due to the higher number of vascular bundle
that can give high density and more strength. |
