Abstract

Palm midrib is a waste in oil palm plantations that containing cellulose, hemicellulose and lignin compounds. Palm midrib pyrolysis will produce phenol derived from lignin. The purpose of this study was to obtain phenol compounds as a function of time and temperature. The pyrolysis process was carried out at 200 °C, 300 °C, 400 °C, 500 °C and 600 °C with variation of pyrolysis time of 30 minutes, 60 minutes and 90 minutes. The analysis was performed using UV-Visible Spectrophotometer. The content of phenol compounds in liquid smoke increases with the rise of temperature and pyrolysis time. The highest total phenol content in liquid smoke was obtained at 600 °C for 90 minutes pyrolysis, which was 17.966%.

Abstract

The purpose of this study was to determine the best of combustion time and temperature of ash production from kapok fruit peel ( Ceiba Petandra ) to get the most potassium. The experiment was begun to dry kapok fruit peel for 24 hours at oven with temperature 110 oC and combustion to obtaine the ash from kapok fruit peel. The combustion was done by muffle furnace which time variables were from 3 hours, 4 hours, 5 hours, and 6 hours and burning temperature variables were from, 500 oC, 550 oC,600 oC, 650oC. The potassium that contained in ash have been extracted by distilled water with volume 30 ml for 24 hours. Observed responses were normality, pH, ash content, and potassium oxide content (% K2O). The best result of ash was in 3 hours with temperature 500 oC. The ash was analyzed by using AAS Atomic Absorption Spectroscopy, and 35.91 % of potassium oxide (K2O) content was obtained as maximum result.
