Improving the quality of liquid smoke from pyrolysis of oil palm fronds with the adsorption–distillation purification process

The purpose of this study is to review the diversification process of oil palm fronds into commercial liquid smoke products. The pyrolysis process of oil palm fronds at 250 °C for 2h was performed to produce crude liquid smoke and followed distillation process at 125, 150, 175 and 200 °C for 15, 30, 45, and 60 min to separate tar as a contributor dark color in liquid smoke. By titration method, the distilled liquid smoke has 5.15% of acetic acid at pH = 2.3 and this result in accordance with FAO standard. The composition of an organic acid, carbonyl, and phenolic compounds were 45.46, 23.08, 29.60 percentages, respectively in distilled liquid smoke and classified as refined liquid smoke. These results indicated that liquid smoke generated from oil palm fronds has a good prospect as a commercial product and suitable for food preservative in the further study based on chemical characteristics.

The total content of phenol compounds present in the liquid smoke can be extracted either by using polar or non-polar solvents. Polar and non-polarsolvents are often used to extract phenol compounds from plants. Extraction of phenol compounds was performed by using ethyl acetate and hexanesolvents at 40° C, 55° C and 70° C within 60, 120, and 180 minutes. The highest total content of phenol compounds is obtained through extractionprocess at 70o C within 180 minutes using ethyl acetate solvent, which is 103,394 mg/g. While, the lowest one is obtained through extraction processat 40o C within 60 minutes using hexane solvent, which is 13,697 mg/g. The phenol compounds obtained are syringol and guiaicol compoundsusing ethyl acetate solvent within 180 minutes, at the temperature of 70o C, which is 5,44% and 3,97%.

This research was conducted in Asahan Regency, to see the study in general. Meanwhile, a detailed study was conducted in the sub-districts chosen to represent all the sub-districts in Asahan Regency. The study was conducted for 2 (two) months, from September to December 2016. The research sample was 70 cattle farmers spread in Air Batu District as many as 37 people, Aek Kuasan District as many as 25 people and Meranti District as many as 8 people. Analysis of the development strategy was carried out using the SWOT (Strengths Opportunities Weaknesses and Threat) analysis method. The conclusion is that the development of cattle business which is given alternative feed for oil palm fronds in Asahan Regency is still possible because the strength and pelauang factors have the greatest value from the weakness and threat factors. The priority sequence of strategies for developing cattle business which is given alternative feed for oil palm fronds in Asahan Regency is to form cattle breed cooperatives so that there is no price difference that is too large, improve the quality of human resources for cattle farmers, develop product innovations, increase access to capital to increase production , increasing cooperation with oil palm farmers in order to obtain raw material for midribs, increasing demand for cattle by expanding markets, developing efficient marketing systems, improving the quality of cattle.
