Utilization of local West Sumatra bamboo for laminated bamboo board with different adhesives

Abstract

The purpose of this study was to study the physical and mechanical properties of laminated bamboo boards by using several types of adhesives for different purposes of use. The research design is done explorative, ie reveal facts that may or may not be revealed. Where each observation is done 3 times repetition and the data obtained will be discussed descriptively. The research treatment was A = PVAc adhesives; B = Gambier Adhesives and C = Phenol Adhesives. The results of Laminated bamboo research with 3 types of PVAc adhesive, Gambier and Phenol Formaldehyde were found that the difference of adhesive type usage on bamboo laminated has significant effect on density, fracture (MOR) and internal stickiness (IB) and delamination, but no significant effect on water. All laminated bamboo test parameters obtained meet National Standard Indonesia for plywood. The best laminated bamboo is using Phenol Formaldehyde adhesive with the density value of 1.02g/cm3, water content 13.00%, brokenness 486.84 kg/cm2, internal stickiness 8.40 kg/cm2 and delamination 1.77%. Based on the research that has been done, it is advisable to do advanced research of bamboo laminated with bamboo arrangement with different angle.
