Abstract
Citronella oil is one of the essential oils derived from the leaves and stem of lemongrass (Cymbopogon nardus). At present, most of the lemongrass oil industry in Indonesia is still in the form of upstream industries which only provide crude purified oils with low purity for export with a fairly low sales value. Technology in improving the purity of citronella oil needs innovation in following the development of the industrial revolution 4.0. This article presents an overview of the research opportunities in the development of distillation for fractionating citronella oil referring to automation of optimization processes in the vacuum fractional distillation accompanied by inspection of the quality of essential oil isolation run in the line process based on smart sensors integrated in a computer program. The combination technique of quality control of essential oils in line process system combined with the optimization technique of the vacuum fractional distillation process has not been studied by advanced researchers. Therefore, this study has a state of the art process engineering and smart sensor-based quality control systems that can be developed for strengthening the Indonesian citronella oil industry.
Highlights
Introduction and Literature ReviewThe quality of essential oils, especially citronella oil, is determined by the purity factor
Based on review that has been carried out in the present condition, the study of vacuum fractional distillation of citronella oil has a research gap that has not yet filled by previous researchers, namely in the process control slot accompanied by quality testing in line using a smart sensor system, that is, the sensor system which is assembled in addition to controlling the operation of the process automatically can provide information on the quality of essential oils that are produced in real time
The automatic system of essential oil fractionation distillation process has the potential to be able to increase the productivity of citronella oil efficiently and environmentally friendly, the application of smart sensor systems that support process performance can be informative in facilitating process control and the quality of citronella oil produced
Summary
Introduction and Literature ReviewThe quality of essential oils, especially citronella oil, is determined by the purity factor. The requirement of essential oil farmers in the future, to improve the quality of essential oils through fractionation distillation, needs technology support both process optimization and inspect quality control that is fast method, easy, low-cost and real time.
