Abstract
The increasing of hardwood utilization as a construction material make it expensive. To solve that problem is by using the sengon wood and coconut wood. One of technology to improve the quality of Sengon wood and Coconut wood by using the laminate method. The test object in this study made by glueing the two sengon wood with 60MDGL PVAC adhesive also the same with coconut wood. The variations of squeezing pressure using are 1 MPa, 2 MPa, and 3 MPa. It is hoped that this research can determine the effect of squeezing force to the the shear strength of wood connecting. The results showed that the shear strength values for Sengon wood with squeezing pressure of 1MPa, 2MPa, and 3MPa are 154,59 kg/cm2, 197,49 kg/cm2 and 277,07 kg/cm2 while for coconut wood are 17,18 kg/cm2, 31,77 kg/cm2 and 39.64 kg/cm2. It can be concluded that the maximum shear strength of sengon sample more that 3 times also the maximum squeezing force of gluing sample is 3 MPa.
