| dc.description.abstract | This study investigates the potential of oil palm starch extracted from oil palm trunk to be used as binder for particleboard. Two types of oil palm samples were prepared, which was soaked with sodium metabisulphite only with 1000 mL of 0.5 % (w/v) in aqueous solution, and another type of sample used 0.2 % sodium metabisulphite and 0.5 % of lactic acid as a catalyst in oil palm starch extraction methods in order to get higher yields of starch collection. Preliminary studies were also carried out to get optimum condition for the particleboard manufacturing. In this study, the commercial corn starch was used as a comparison for oil palm starch performance. Both types of oil palm and corn starch were then chemically modified with polyvinyl alcohol (PVOH) and crosslinked with boric acid, respectively. Physical blending by adding 3 % of Nano silicon dioxide (SiO2) in the modification method was conducted accordingly. Both types of oil palm and corn starch were evaluated at four different starch and PVOH ratios, such as 100 % native starch; 90 % starch with 10 % polyvinyl alcohol (PVOH); 90 % starch with 10 % polyvinyl alcohol (PVOH) plus 3 % of Nano silicon dioxide (SiO2); 80 % starch with 20 % polyvinyl alcohol (PVOH); 80 % starch with 20 % polyvinyl alcohol (PVOH) plus 3 % of Nano silicon dioxide (SiO2); 70 % starch with 30 % polyvinyl alcohol (PVOH); 70 % starch with 30 % polyvinyl alcohol (PVOH) plus 3 % of Nano silicon dioxide (SiO2). Basic characterizations, physicochemical and particleboard strength properties were analyzed in this study. The results indicated that by steeping oil palm chips in sodium metabisulphite within 48 h is the optimum condition to extract starch from oil palm trunk. | en_US |
