The common practice of using toxic chemicals as a preservative for rubberwood is much of a concern regarding environmental issues, its effect on human health, and compromising the wood's strength. This study focuses on the alternative strategy to preserve rubberwood using sodium acetate and sodium butyrate. These two salts were obtained from the reaction between sodium hydroxide and the fermentation products of landfill leachate, namely acetic acid and butyric acid. The effect of these salt concentrations and treatment duration on the rubberwood were studied and assessed from the biological decay, mechanical and chemical aspects. Almost all treated rubberwood subjected to decay by Phanerochaete chrysosporium, Trametes menziesii, species fungi A (white-rot), and species fungi B (brown-rot) have lower mass loss than untreated rubberwood. Treatment with 0.5M sodium butyrate was the best concentration in protecting the wood from degradation caused by fungal attacks. For the mechanical test, most of the salt concentrations positively impacted the bending strength and modulus of the treated rubberwood. Lastly, a chemical test conducted on rubberwood treated with 0.75M sodium butyrate for 21 days gave the highest retention and penetration of the salt into the rubberwood. [ABSTRACT FROM AUTHOR] |
