dc.description.abstractIn this study, the effects of additives on the properties of oil palm trunk binderless board were evaluated through a series of mechanical, physical and chemical analyses. Ten types of binderless boards from oil palm trunk particles were made that include control boards, boards with addition of additives namely xylose, sucrose, glucose and potato starch, boards made from oil palm trunk particles that were extracted with hot water, and boards made from oil palm trunk particles that were extracted with hot water with addition of additives. All binderless boards were made to a target density of 0.8 g/cm3 and pressed at 180°C for 20 minutes. Chemical changes that may occur in the binderless board were evaluated by chemical analyses including extractives, holocellulose, alpha-cellulose, lignin content, starch content, individual sugar and total sugar content. Spectroscopic characterization was done using Fourier Transform Infrared (FT-IR) spectroscopy to detect the presence of the functional group that exists in oil palm binderless boards. The structural changes of the manufactured panels before and after the addition of additives were viewed using Scanning Electron Microscopy (SEM). The results showed that addition of additives particularly sugar onto the board made from oil palm trunk particles with and without extraction increased the modulus of rupture (MOR) and internal bond (IB) strength and also improved the thickness swelling (TS) and water absorption (WA) values. Generally, most of the panels met the Japanese Industrial Standard (JIS A-5908) for the Type 8 and some satisfied the requirements for Type 13 and Type 18. Based on the findings of this study, it can be suggested that sugar play a major role in the bonding of the binderless board. Addition of additives especially sugar onto the particleboard enhanced and improved the physical and mechanical performances of the boards. Thus, it can be proved that the sugar in the boards contributed in the self-bonding between particles and the other particles to occur.en_US
