| dc.description.abstract | The quality increasing of oil palm trunk (Elaeis guineensis Jacq.) by compregnated with
dammar resin (Agathis dammara) has been performed. Sellulose as a natural polymer of
the oil palm trunk interacted with dammar resin and the mechanical properties of the oil
palm trunk was increased. OPT compregnate with dammar resin was performed in
vacum compregnator with the duration time of two seconds. The temperature of
compregnate was room temperature with 0%, 10%, 20%, 30%, and 40% concentrations
of dammar resin. The compregnated oil palm trunk was analyzed by measurement of
mechanical analysis of Modulus Elasticity (MoE) and Modulus Rupture (MoR),
Mophology was analyzed by Scanning Electron Microscopy (SEM), Functional group
was analized by Fourier Transform Infra Red (FT-IR) and Thermal Analysis by
Thermogravimetry Analysis (TGA). The result showed optimum condition was at under
of OPT with dammar resin concentration of 20% with value MoE was 281,141 Mpa and
dammar resin concentration of 40% with value MoR was 1,010 MPa. The result of
functional group analysis at OPT and compregnated of OPT by FT-IR showed the
suitable spectrum, there is no change in spectrum but the only decrease of peak area that
show physical interaction. Morphology analysis by Scanning Electron Microscopy
(SEM) by zoom 500 times, showed the morphology of compregnated OPT space of
parenchyma has been covered by resin. The conclusion that morphology of OPT was
changed and OPT was compregnated. Thermal analysis by Thermogravimetry Analysis
(TGA) showed at temperature of 400oC OPT has been lost of mass less than 50% was
29,65% and OPT compregnated has been lost of mass not less than 50% was 68,664%
in OPT compregnated with 20% concentration of dammar resin, and 67,681%. In OPT
compregnated with 30% therconcentration of dammar resin. | en_US |
