Abstract

This study aims to analyze the comparison of the adhesive shear strength value of the treatment used in the test sample, namely the difference in the type of adhesive with the difference in surface treatment of the adhesive plane. Analysis of variance (ANOVA) and LSD (Least Significant Difference) further test. The results of the analysis of variance showed that the effect of adhesive type (A) and surface treatment (B) on the adhesive shear strength of the laminate was very significant, while the interaction (AB) was not significant. Tests of physical and mechanical properties of laminated wood were carried out based on the JAS 234 - 2007 standard. The average moisture content of laminated timber was 11.59% and the average normal density was 0.329 g/cm³. The value of adhesive shear strength with A1 (epoxy) treatment of 69.79 kg/cm2 is greater than A2 (PVAc) of 63.98 kg/cm2 , while B3 (sanding) with the highest average of 72.86 kg/cm2 followed by B2 (planing) of 65.42 kg/cm2 and the lowest B1 (sawing) of 62.38 kg/cm2 . For the percentage of wood damage in the A1 (epoxy) treatment of 76.30% is higher than A2 (PVAc), while the treatment while B3 (sanding) with the highest average of 76.55% followed by B2 (planing) of 72.80% and the lowest B1 (sawing) of 71.00%, and has met the standard of JAS 234: 2007 (>54 kg/cm²).

Abstract

The need for wood and plastic products is increasing, it is necessary to optimize the utilization of waste by processing it into plastic composite boards. This study aims to determine the best composition with raw materials of sengon wood powder (Paraserianthes falcataria L.I.C Nielsen) and rice husk powder (Oryza sativa) as filler with a ratio of 50% : 50% and polyprophylene plastic (PP) as a matrix. This treatment uses 3 compositions, P1 (40 % PP : 60 % SS) P2 (50% PP: 50% SS), and P3 (60% PP: 40 % SS ) was hot pressed with a pressure of 30 bar for 20 minutes at a temperature of 180°C with 3 replications for each treatment. The best result was obtained in the P3 (60 % PP : 40 % SS) with an average density value of 0.83 g/cm3, moisture content 1.52%, water absorption 32.16%, thickness swelling 9.34%, MoE 4,057.85 N/mm2, MoR 42.39 N/mm2 and IBS 0.21 N/mm2 Some test results have met plastic composite board standards according to JIS Particle Board A 5908-2003, JIS Plastic Board A 5741-2006 and SNI Plastic Board SNI 8154-2015.
