Abstract
Wood is biodegradable material. Using wood in long term requires preservation and protect. Wood preservation is able to lengthen its life at least three times than non-treated wood. Lignocelluloses biomass bio-oil is potential substrates as wood preservative. One of potential source as lignocelluloses biomass bio-oil is oil palm trunk. Production of lignocelluloses biomass bio-oil is influenced by numerous parameters such as, moisture content of wood, temperature and time of combustion. Response Surface Methodology (RSM) is a powerful and efficient mathematical approach widely applied in the optimization of process. The objectives of this research are to search an optimum condition of production of lignocelluloses biomass bio-oil of oil palm trunk. Optimization of production process of lignocelluloses biomass bio-oil is carried out by using RSM with three variable designs as introduced by Box-Behnken, including pyrolysis temperature at 350°C, 400°C and 450°C; pyrolysis time of 60minutes, 90minutes and 120minutes; and moisture content of 10%, 12.5% and 15% with 15 runs. The result shows that optimum production of lignocelluloses biomass bio-oil of oil palm trunk is obtained at pyrolysis temperature of 446.11°C; pyrolysis time of 119.98minutes and oil palm trunk moisture content of 9.26% and rendemen of production was 42.05%. This information will increase the optimization production of wood preservatives material from oil palm trunk in industrial scale.
