HASIL PLAGIASI SIFAT FISIS DAN MEKANIS PAPAN KOMPOSIT DARI SERAT BATANG KELAPA SAWIT (Elaeis guineensis Jacq) DENGAN BERBAGAI KOMPOSISI PEREKAT PVAC

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.
