EFFECT OF WIDTH, THICKNESS, AND LENGTH ON STATIC BENDING OF RED MERANTI (Shorea sp.)

Abstract

This study aim to determine the wood size effect of the width, thickness (depth), and length on the static bending strength of red meranti (Shorea sp.). The results of the study are expected to provide information and evaluation in the application of wood as the structural material. Specimen testing uses small specimens and defects free of the clear solid wood standards DIN 52182-77 for moisture content, DIN 52183-76 for wood density, and DIN 52186-78 for static bending strength (Modulus of Elasticity/MoE and Modulus of Rupture/MoR). Statistical analysis (ANOVA) and LSD (Least Significant Difference) test at 95% confidence level were used to analyze the significant effect and difference between treatments. The results showed a significant difference between treatments, where increasing in width will decrease the average value of static bending strength (MoE and MoR), and in contrary increasing in thickness (depth) and length will increasing the average value of of static bending strength (MoE and MoR).
