| Summary: | Meditation is a mind and body exercise that has many methods and is found in
various cultures, spiritual traditions, and healing systems throughout the world.
In Islam, there are meditation activities such as prayer, dhikr, prayers,
recitations, and Tafakur. Tafakur is a spiritual activity that prioritizes
contemplation/high-level thinking regarding personality, social, scientific, and
spiritual matters. This research aims to determine the character of brain waves
and their complexity in Tafakur activity using Power Spectral Density (PSD) and
Spectral Entropy (SE) as spectral analysis.
Data collection was carried out using a 5-channel emotiv insight device with a
sampling frequency of 128 Hz on 15 practitioners with three categories based on
activity intensity each week by applying initial rest, meditation, and final rest
phases sequentially. Then, PSD analysis was carried out on delta (0.5 – 4 Hz),
theta (4 – 8 Hz), alpha (8 – 13 Hz), beta (13 – 30 Hz), and gamma (30 – 45 Hz) to
compare graphical patterns of normalized PSD among all phases and compare
the total normalized PSD among all phases. Meanwhile, SE analysis is carried
out by comparing each entropy among all phases.
The results show that the normalized PSD graphic pattern for each band during
Tafakur with initial rest and final rest conditions is similar. However, the total
normalized PSD heatmap shows differences in the characteristics of Tafakur
activities for each practitioner and is not related to the practitioner category.
Through this heatmap, it is also known that the frontal channels experience
bilateral activity, but the T7, T8, and Pz channels indicate different functions of
parts of the brain. Meanwhile, the SE heatmap shows an increase in entropy in
theta, alpha, beta, and gamma bands during Tafakur when compared to the initial
rest and final rest conditions, which indicates active awareness and intensifies the
information in the signal.
