Abstract

The objective of this research is to research the effect of particle soaking to physical and mechanical properties particleboard that resulted. The best result of particleboard is particleboard with treatment of hot water soaking. From this result obtained average of physical properties of particleboard (i.e. density, moisture content, water absorption, and thickness swelling) are 0.7 g/cm3; 9.58%; 52.27%; 10.05%. While the result average of mechanical properties of particleboard (i.e. Modulus of Rupture, Modulus of Elasticity, Internal Bond and Screw Holding Power) are 118.79 kg/cm2; 8.909 kg/cm2; 1.85 kg/cm2; 28.40 kg. Key words: Soaking, bagasse, particleboard, physical and mechanical properties References

Abstract

For optimum utilization of coconut wood, there are necessity to improve the quality of the wood caused by higroscopicity, low dimensional stability, and extreme variability of dimension in lateral direction. The purpose of the research were to analyze the characteristics of coconut wood that had been treated by heating and densification. The treatment consist of one or two hours heating, one hour heating combined to 10 or 20% densification, two hours heating combined to 10 or 20% densification. Temperature that applied for all specimen were 180 oC. The research results are as follows: (1) Heating treatment combined to densification effective to reduce higroscopicity of coconut wood, (2) Heating treatment for two hours are suffice as pretreatment to densify the soft part of coconut wood for 20%, (3) Dimensional stability of coconut wood may improve using heating combined to densification treatments that indicated by decreasing rate of dimensional change, (4) Heating and densification treatment effective to improve the hardness of soft part coconut wood.
