Abstract

The system  extracting essential oil from herbal plants by using rice husk as fuel have the objective is to develop a system for extracting essential oils from medicinal plants by using rice husk as fuel and to analyze the extracted essential oils. The researcher designed the essential oil extraction system to find the essential oil extraction work and analysis of essential oils extracted using physical and chemical methods. The results showed that the thermal efficiency of the extracting pot was 841.39 KJ. The thermal efficiency of the biomass burner for extracting oil from galangal and lemongrass were 15.01% and 14.84% which is considered to have a highly efficient thermal system. The extracted essential oils of galangal and lemongrass essential oils were as follows: 201.67 ml and 216.67 ml respectively. The aroma of essential oil galangal and lemongrass as follows Very strong pungent and pungent aroma, respectively, the color of the essential oils galangal and lemongrass as follows have Golden yellow and red brown respectively. Acidity-base of essential oil galangal and lemongrass PH value as follows 5.12 and 4.39 respectively. Which is considered to be a weak acid according to the standard of essential oils from lemon grass and galangal and the concentration of galangal and lemongrass essential oils were as follows: 0.04 and 0.14 respectively. From the research, it can be concluded that the essential oil extraction system And the essential oils extracted with high efficiency can be used to extract essential oils from medicinal plants. And able to be further made into herbal products.
