Natural preservative from the liquid smoke of ebony wood as anti-subterranean termites (Coptotermes curvignathus Holmgren)
Abstract
Chemicals have been used as wood preservatives because they prevent the attack of termites and fungi. However, since these chemicals can harm the environment and humans, their use is limited. This study introduces a natural preservative that is not harmful to humans and also environmentally friendly. This study aims to identify and produce lignocelluloses bio-oil biomass and also evaluate lignocellulosic bio-oil biomass from Ebony wood smoke as a wood preservative to prevent subterranean termite attack (Coptotermes curvignathus Holmgren) on Red Jabon wood with observed parameters is wood retention, wood weight loss, and termite mortality. This study uses a complete randomized design of 3 factors and 5 replications. There are 3 levels of treatment: different concentrations of preservatives (ebony lye + BAE), pyrolysis temperature and preservative duration. The treatment of the concentration of preservatives consists of 5 compositions, namely: control with solvent from liquid smoke of ebony wood = K, ebony wood smoke + BAE 2% = E1, ebony wood smoke + BAE 3% = E2, ebony wood smoke + BAE 4 % = E3, ebony liquid smoke + BAE 5% = E4. The temperature of pyrolysis is 400ºC and the immersion time is 24 hours. The result shows that the compounds contained in ebony liquid smoke consist of Phenol, 2,6-dimethoxy-4- (2-propenyl) (CAS) 4-Allyl-2,6-dimethoxyphenol; Hexanoic acid, 1-methylethyl ester (CAS) isopropyl hexanoate; Pentanoic acid, 4-oxo, ethyl ester (CAS) Ethyl levulinate; Acetaldehyde (CAS) Ethanal; 4-Methoxy-3 – (methoxymethyl) phenol. Wood retention on wood samples of red Jabon from 55.77-126.604 g/cm3, decreased weight of wood is 7.40 – 8.92% and termite mortality from 95.5% – 100%.The best solution to prevent of wood from attact of termite and fungi without harmful to humans and also environment by using biochemical extract of lignocellulosic bio-oil biomass from Ebony Wood.
