Optimizing the effect of various ethanol concentration as drying agent to the mechanical properties of oil palm lumber (elaeis guineensis) / Siti Fadhilah Rosli
Wood-based industry in Malaysia is dependent on the natural forest resources and forest plantations. The high demand of this resource makes it more scarce and expensive. Currently the industries are searching for other resources to overcome the over dependence on local timber. The waste biomass...

| description |
Wood-based industry in Malaysia is dependent on the natural forest
resources and forest plantations. The high demand of this resource makes it
more scarce and expensive. Currently the industries are searching for
other resources to overcome the over dependence on local timber.
The waste biomass from the oil palm industries can be turned into
value-added products providing an alternative raw material for the wood
industry, but OPT (Oil Palm Trunk) was reported to be difficult to dry, not only
because of its extremely high green moisture content, but also its drying
defects. The objectives of this study were to determine mechanical
properties of Oil Palm Lumber (OPL) and the effect of different ethanol
concentration on mechanical properties of OPL. Samples sized were cut
according to the standard size of bending, compress and shear tests that
were soaked with various concentration of ethanol and soaking time with
dried by oven method. Response Surface Methodology (RSM) was
conducted to develop regression equation of OPL layer in different ethanol
concentration. The result showed. that bending (MOE) for outer layer was
3534.83 N/mm2 while core layer was 1667.36 N/mm2. The bending (MOR)
strength for outer and core layer was 32.2352 N/mm2 and 17.8545 N/mm2
respectively. The compression strength of outer layer was 16.1238 N/mm2
and 5.58209 N/mm2 for core layer. Meanwhile, for outer layer of shear
strength was 2.4196 N/mm2 and at core layer was 2.2282 N/mm2. This
research found that the drying method of OPT using ethanol had been
successful and showed that ethanol had an effect on mechanical properties
of OPT .in drying the outer and core layer of OPT for 24 hours with a
temperature of 80°C by using oven and only 55% of the ethanol
concentration was suggested to obtain the best mechanical properties of
OPT. |
