Abstract

Abstract
Volatile oil, or commonly known as essential oil, is a concentrated liquid that is
insoluble in water and contains aromatic compounds. One source of essential oils
is citronella. The extraction of lemongrass oil is carried out using the
hydrodistillation method, with consideration of the solvent used in the form of
aquadest so that it is easier to obtain and the time required for extraction is
relatively faster. To increase the efficiency of the extraction process, kinetic
modeling was carried out. This aims to predict the results before the extraction
process is carried out, and considering that there are still few studies that discuss
the kinetic model. So in this study, we modeled the process of extracting essential
oils from lemongrass (Cymbopogon winterianus Jowitt) in 7 different kinetic
models including pseudo-first-order and pseudo-second-order kinetics models in
linear and nonlinear forms. By considering the value of the coefficient
determination, from the 7 kinetic models, a non-linear form of pseudo-first-order
(Non PFO-1) was chosen because it has a high R
2 value, the smallest percentage
of q value and also small SSE, RMSE and MSE values.
