Optimasi produksi dan sifat fungsional asap cair kayu karet Optimation of production and fungsional properties of liquid smokeproduced from tievea rubber wood

Optimization of production process of liquid smoke from rubber wood was carried out by using response surface methodology (RSM) to optimize production of liquid smoke, phenol and carbonyl in liquid smoke. The objectives were to look for optimum condition for production of liquid smoke containing phenol, carbonyl and acid contens and analize the components of liquid smoke. The study applied RSM with three variable design i.e. pyrolysis temperature (x), at temperatures of 350 (-1), 400 (0) and 450 °C (1), pyrolisis times for 60 (-1), 90 (0) and 120 minutes (1) and moisture contens of 10 (-1), 15 (0) and 20 % (1) with 15 runs. The rubber wood composed of cellullose 45,67 %, hemicellullose 28,32 % and lygnin 16,69 %. Optimum production of liquid smoke was obtained at temperature of 420.87 °C for 99.60 minutes, moisture content of 16.55 % and the production was 54.39 %. The optimum phenol content was obtained at temperature of 388.18 °C for 99.74 minutes and moisture contens of 23.40 % and phenol content obtained was 1.78 %. The optimum carbonyl contens was obtained at temperature of 395.14 °C at 93.46 minutes and at moisture content of 15.78 % and carbonyl content obtained was 5.55 %. The optimum acid content was obtained at temperature of 388.24 °C for 91.74 minutes and at moisture contens of 15.18 % and acid content obtained was 5.55 %. key word : optimization, liquid smoke, phenol, carbonyl, acid, rubber woo
