| dc.description.abstract | Palm oil plantation is growing rapidly in Indonesia. In 2011, palm oil plantations in
Indonesia have reached 8,91 million ha area. It is produce waste in form of palm
midribs in large number around 6.400-7.500/year per 1 ha plantation. One of the way
to handle and increase the value of palm midrib waste is by pyrolysis process. This
study is aim to analyze the effect of pyrolysis temperature and time to liquid smoke
characteristic. Pyrolysis of palm midrib powder was processed at 150 oC, 200 oC, and
250 oC for 30, 60, 90 minutes. The study found that the yield of liquid smoke tends
to increase with rising pyrolysis temperature and time until the condition when un condensable gas production more so that the increase of pyrolysis temperature and
time will further decrease the yield. The highest yield of liquid smoke obtained at
250 oC for 30 minutes, is 20,69%. The best quality of liquid smoke obtained in the
pyrolysis 250 oC for 90 minutes which contain 16,29% acid, 4,57% phenol, and pH
2,6. | en_US |
