Abstract:
The purpose of this study was to determine the effect of PVAc adhesive composition
on the physical and mechanical properties of the composite boards of palm oil stems and
determine the best test example from a technical and economic point of view. This research will be
carried out at the Banjarbaru Forestry Faculty Workshop. Research time ± 3. There are 3 levels
(levels) of the PVAc adhesive composition tested, namely 40%, 45%, and 50%. The parameters of
the composite board properties studied were physical properties, including: Moisture content and
density, as well as the mechanical properties that fracture strength (MoR) and modulus of elasticity
(MOE). The results showed that the physical and mechanical properties of composite boards were
strongly influenced by the adhesive composition, the more the adhesive composition is used, the
better the composite board properties, especially in terms of water content and MoR, where the
results show that the water content is decreasing and the MoR is increasing. Nevertheless the use
of a 40% adhesive composition has been able to produce a composite board that can meet SNI
standards No. 03-2105 2006. Properties of palm oil stem waste composite boards made with PVAc
adhesive (Crosslink X-PVAc) moisture content ranged from 9.49% - 13.07%, density 0.494 - 0.559
gr / cm³, and MoR 20.613 - 22.483 kg / cm².
