Peningkatan Sifat Fisik dan Sifat Mekanik serta Ketahanan Rayap Kayu Simalambuo (Loppopethalum Spp.) dengan Teknik Impregnasi Menggunakan Kombinasi Asap Cair dan Minyak Silikon

Abstract

Wood is a renewable natural material. Many methods have been used in wood preservation efforts. The use of liquid smoke is very effective in increasing wood resistance to fungi and termites. Researchers combined liquid smoke and silicon oil with heat treatment techniques as an effort to preserve wood. This research was conducted using the impregnation method by combining liquid smoke and silicon oil. Based on the results of the study, enhancement dimensional stability was obtained by increasing the value of Antiswelling Efficiency (ASE) to 66% and decreasing the ability of water absorption (Water Absorption) to 150.5%, increasing the wood resistance class to class I (Highly Resistant) with the smallest weight loss of (Coptotermes curvignathus Holmgren) 0.0103%, and significantly influence the value of Modulus of Elasticity (MoE) and Modulus of Rupture (MoR) with the highest value of Modulus of Elasticity (MoE) of 16480 Kg/cm2 and the highest value of Modulus of Rupture (MoR) of 9433.71 Kg/cm2. It can be concluded that the use of a combination of silicon oil and liquid smoke can increase the durability of wood.
