Hybrid Adhesive Made from Citric Acid and Sucrose for Particleboard Composed of Sengon (Paraserianthes falcataria (L.) Nielsen) Veener By-Products and Sorghum Stalk

Particleboard is a product of wood technology engineering made particles and other lignocellulosic materials which are bonded with synthetic adhesives. As an information, utilization natural adhesive for particleboard still limited. This study aimed to determine the influence hybrid from citric acid sucrose properties composed Sengon veener by-products sorghum stalk. The content used was 15% 25% that calculated dry weight particles. mixture ratio both were 100:0, 75:25, 50:50, 25:75, 0:100 (% w/w). manufacture set on target density 0.8 g/cm3 under press temperature 200o C 10 minutes. Mostly, shown be affected by composition between met Japan Industrial Standard A 5908:2003. value modulus elasticity, rupture, internal bond, screw holding ranged about 1.21-3.49 GPa, 12.77-20.24 MPa, 0.18-0.90 MPa 167.71-321.27 N. 50:50 has best physical mechanical requirement
