【 摘 要 】

The objective of this study is to determine the activity of Theta brainwave as the response to Lavender aromatherapy inhalation of postgraduate students with academic stress condition. This research involved 10 postgraduate students consisted of 5 males and 5 females who were still pursuing their final research and were recruited based on assigned criteria and filled two modified questionnaires to determine the stress category. The procedure of Lavender aromatherapy inhalation was given intentionally for a period of 16 days of experiments for 15 minutes of each day. Evaluation of brain electrical activity focused on Theta (frequency 4-7Hz) and were recorded by Electroencephalograph (EEG) EMOTIV EPOC from 6 channel electrodes on the scalp (AF3, AF4, T7, T8, P7, P8). Essential oil compound from Lavender was evaluated by using GCMS (Gas Chromatography Mass Spectrometry). Data were analysed by comparing baselines before treatment and two weeks after aromatherapy administration using General Linear Model and Paired t-test statistical procedure. The result revealed that: (1) the main constituents of Lavender essential oil are linalool (20,11%) and linalyl acetate (26,34%), (2) there was no significantly increase in Theta power both in women and men (p > 0,05), (3) there was an asymmetry of Theta brainwave pattern at P7 and P8 channel in women. The constituents of Lavender essential oil activate olfactory neuron and modulate inhibitory neurotransmitter to influence EEG pattern.
