Abstract
Oil palm plantations produce significant amounts of oil palm fronds as a waste. The availability of oil palm fronds is very potential to be processed into liquid smoke. Liquid smoke is obtained from the condensation of vapor from smoke as a result of decomposition of organic compounds contained in oil palm fronds in the pyrolysis process.This study aims to determine the increased quality of liquid smoke through the adsorption process by using activated zeolite and distillation with used pyrolysis temperature were 400 °C, 500 °C, and 600 °C for 60 minutes, 90 minutes, and 120 minutes. Analysis of the composition of liquid smoke compounds using by GC-MS Shimadzu QP 2100 brans. Parameters observed included total carboxylic acid, phenol, and carbonyl. The results of the study obtained the highest carboxylic acid content after distillation obtained was 89.58% at pyrolysis temperature of 500 °C 120 minutes, phenol was 7.32% at pyrolysis temperature of 600 °C 120 minutes, and carbonyl was 35.58% at pyrolysis temperature of 400 °C60 minutes.
