Waste Utilization as Fine Coconut Fiber for Core and Wood Waste Bayur to The Face Layer of The Physical and Mechanical Properties of Particle Board Produced

This study aims to determine the effect of wood particle bayur comparison to the outer layer of coconut husk particle board smooth the physical and mechanical properties of the resulting particle board . The design used was completely randomized design ( CRD ) with 5 treatments with 3 replications for each treatment used is the use of wood particles bayur as the outer layer of particle board and refined coconut fiber as a core that is 80 % : 20 % , 70 % : 30 % , 60 % : 40 % , 50 % : 50 % , 40 % : 60 % observational data physical and mechanical properties were analyzed using analysis of variance if significantly different then performed with a further test of Duncan's New Multiple Range Test ( DMNRT ) at the 5% significance level . Observations made on the physical properties of particle board include : water content , water absorption and thickness expansion. The mechanical properties of particle board : strength broken , the pressure parallel and bonding strength. Based on the research that has been carried out showed that the utilization of wood waste bayur as the outer layer of particle board on a percentage varying significantly different effect on strength broken , water content , water absorption , expansion of thick , strength pressure bonding parallel to the internal surface . The results show the percentage of particle board with wood bayur with delicate coconut husk ( 40:60 ) is the best board with a water content of 6.11% , water absorption 20.56 % 10.93 % thicker expansion, density of 0.84 % , bonding strength of 56.90 kg / cm 2 pressure and parallel fiber determination 146.65 kg /cm 2.
