Knowledge of the mechanical properties of this type of wood is very important and necessary as a basis for designing the structure of wood materials. Wood is a natural organic material and it can be degraded by organic life forms via bacteria, fungi and insects. Normally, borax-boric acid will be used for wood preservation and it is an inorganic form, which is not environmental-friendly used and for the long term effects, the wood will produce leached. This study aims to determine the results of testing the mechanical properties in the form of tensile strength and compressive strength of durian wood preserved by extract of kecubung fruits, which is in the form of organic material. The wood preservation method used a cold soaking method. Experiments were performed by giving differences in the treatment of preservative concentration (0%, 15%, 20% and 25%). Tensile strength test result using the ANOVA test showed that the Fcount (11.85) is higher for the preserved wood compare to the natural wood Ftable (3.24), therefore, the alternative hypothesis was accepted. While the compressive strength test result using the ANOVA test showed that the Fcount (6.18) for the preserved wood is higher than the natural wood Ftable (3.24). Therefore, the alternative hypothesis was accepted. This showed that there is a difference in the average mechanical strength of the durian wood (tensile strength and compressive strength) with the treatment of different concentrations of the kecubung fruits extract. © School of Engineering, Taylor’s University
