| dc.description.abstract | Due to the increasing of wood requirement in Indonesia and
unsufficient wood supply, the Oil Palm Trunk ( OPT ) may be used as
alternative wood in carpentry.
Reactive Impregnation is a technique in this research to modify OPT
using maleic anhydride and poliethylene resin and benzoil peroxide as
initiator. Impregnation is held at the melting point of resin ( 140 °C ) and
pressure ( P ) 0, 1, 2 kg/cm2 for 30, 45, 60 minutes in a pressurized reactor.
. The results indicates that optimum impregnation condition is in the
pressure ( P ) 1 kg/cm2 and duration time is 30 minutes. This is showed by
the increasing of Modulus of Elasticity ( MoE ) and Modulus of Rupture
( MoR) from ( 13062,8 and 145,88 ) kg/cm2 to ( 24826,1 and 240,24) kg/cm2
and density increase from 0,38 gr/cm3 to 0,63 gr/cm3.
Based on Fourier Tranform Infra Red ( FTIR ), Scanning Electron
Microscopy ( SEM ) and X-ray analysis, it is indicated that the resin has been
absorbed into the middle part of OPT specimen.
FTIR spectra of the wood powder also showed various shifts of
absorption peaks, which indicated phys/ca/ interaction between the OPT and
resin molecules. | en_US |
