Optimasi Kadar Asam dalam Asap Cair dari Kayu Karet dengan RSM = Optimization of Acid Contents in Liquid Smoke from Rubberwood with Response Surface Methodology (RSM)

Optimization of production process of liquid smoke from rubber wood carried out by using response surface methodology (RSM) to optimize production of liquid smoke, phenol in liquid smoke. Response surface methodology (RSM) was a collection of mathematical and statistical techniques that were useful for the modeling and analysis of problems in which a response of interest was influenced by several variables and the objective was to optimize this response. Our objectives were to look for optimum condition of production liquid smoke, charcoal, phenol, carbonyl and acid contents in liquid smoke and analyze to component liquid smoke at optimum production. The study was by using use RSM with three variables design as introduced by Box-Behnken. Three variable in this research were: pyrolisis temperature (x), with temperatures of 350 (-1), 400 (0) and 450 (1), pyrolisis times of 60 (-1), 90 (0) and 120 minutes (1) and moisture contents of 10 (-1), 15 (0) and 20 % (1) with 15 runs. The analysis of wood gave the result of cellulose: 45,67 %, hemicellullose: 28,32 % and lygnin :16,69 %. The optimum acid contents was obtained at temperature of 388.24 °C, 91,74 minutes and moisture contents of 15.18 % and acid contents obtained was 16,93 %.
