This study was conducted to develop the method of extracting beta-glucan from the fiber of Elaeis guineensis or oil palm trunk (OPT) and to evaluate its potential. From the previous studies, beta-glucan usually extracted from barley, oats and also bacteria. In this research, wet separation method which is also known as aqueous alcohol method was used to extract beta-glucan from the oil palm trunk fiber. This indirect method of producing beta-glucan was found optimized at conditions of 50% of ethanol as solvent, 4 hours pretreatment duration and temperature of 70ºC. Finally beta-glucan was analyzed by enzymatic method and the percentage of beta-glucan extracted in this study was 34.17 percent.

Elaeis guineensis is an alternative source of raw materials for renewable energy in Malaysia. Thus, to enhance the use of the abundant biomass generated by the oil palm industry in Malaysia, a study was conducted in view of exploring the chemical composition such as sugar potential of this industrial byproduct. In this context, oil palm trunks were separated into individual cell that are parenchyma and vascular bundle to investigate the fundamental research about oil palm trunk. The aim of this study was to examine the chemical composition of parenchyma and vascular bundle of oil palm trunk. The oil palm trunk was kept under shade at room temperature of 28–30°C for 0, 45, and 60 days. The chemical composition analysis was carried out according to TAPPI methods. Based on storage time and different part of oil palm trunk, the result has shown that the sugar content was higher in parenchyma compared to vascular bundle and increase at the storage time of 0, 45, and 60 days while amount of starch showed decrease at the same storage time. It shows that conversion or fermentation of starch to sugar occur in oil palm trunk during storage times of 0, 45, and 60 days, respectively.

High demand for wooden materials and rises in agricultural areas and forest fires increased the importance of composite particleboard instead of using solid woods. Particleboards are among the most popular materials used in interior and exterior applications. The objective of this study was to examine the physical and mechanical properties of phenol formaldehyde particleboard made from oil palm trunk (OPT) with 11% resin content. Two different board thicknesses were use; 12mm and 16mm. The particle size use in this study was 2mm and 1mm. Phenol formaldehyde (PF) was used as the binder. The result showed that modulus of rupture and modulus of elasticity were perform better at 16mm board thickness with 1.0mm particle size and meet the standard. The internal bonding strength was parallel with bending strength.

Oil Palm Trunk (OPT) act as a filler for polymer foam composite has been investigated and proved to have ability to absorb sound. In this study, treatment of wood untreated and treated with acid hydrolysis named as UP5 and TP5 was use as filler. This study was developed to compare the ability of sound absorption based on different composition of filler in polymer foam composite. By choosing the size of <500 µm, three different percentage has been selected which is 10 %, 15 % and 20 % for both conditions. These samples has been tested by using Impedance Tube test according to ASTM E-1050 for sound absorption coefficient, α measurement and Scanning Electron Microscopy (SEM) for determine the porosity for each  samples. 20 % filler loading of UP5 gives highest sound absorption coefficient of 0.97 at 4728 Hz. Meanwhile for 20 % loaded of TP5 gives 0.99 at 3371 Hz. When comparing the sound absorption coefficient for both sounds absorbing materials, TP5 polymer foam composite showed higher value of sound absorption coefficient, α at lower frequency level (Hz) as compared to UP5 polymer foam composite which gives better results in sound absorption.

Biopolymer Film

The research about of the biopolymers film from oil palm trunk starch had been done.  Biopolymers  film  made  by  mixing  of  oil  palm  trunk  starch  (Elaeis guineensis Jacq.) and plasticizer sorbitol with the variation was 2:0,8 ; 2:1,0 ;2:1,2 (g/mL), then the film was molded on acrylic plate and dried in an oven at 40°C for 24  hours.  The results of  the film characterization  show that  the best variation of biopolymers on comparison 2:0,8 (g/mL) with the value of tensile strength was 4,26 MPa, percentage of elongation was 1,87 %, and film thickness was 0,16 mm, then it can be used as reference for addition 2 gram chitosan on the establishment of biopolymer film. It was characterized by tensile strength test with value was 14,00 MPa, pencentage of elongation with value was 3,20 %, and film thickness  with  value  was  0,10  mm.  The  results  of  Differential  Scanning Calorimetry  (DSC)  showed  increasing  of  the  endothermic  temperature  was 115,75 oC and exothermic temperature was 394,56 oC. The results of Thermal Gravimetry Analysis (TGA) showed that at a temperature of 340,1 0C the film to start decomposed. The value of % Swelling was 63,176%. The Fourier Transform Infra  Red  (FT-IR)  result  showed  that  in  biopolymers  film  occurs  physical interaction  only.  As  well  as,  the  antibacterial  activity  analysis  showed  that addition of chitosan on biopolymer film made Staphylococcus Aureus and Escherichia Coli bacterial was great inhibited with index antibacterial value of 0,625  respectively.  From SEM analysis showed  that film had  been  added by chitosan more homogenous than film without chitosan addition. The presence of chitosan addition tend to increase the physical and mechanical  properties of biopolymer film.
