Abstract

Otak merupakan salah satu organ tubuh yang paling penting dan kompleks yang dimiliki oleh manusia yang mengontrol seluruh aktivitas organ tubuh, aktivitas sehari-hari, dan berperan menetukan emosi. Apabila otak terdapat gangguan, maka kendali aktivitas tubuh akan terganggu. Oleh karena itu, diperlukan sebuah alat yaitu electroencephalograph (EEG) yang berperan untuk mendeteksi pergerakan gelombang otak, namun pada penelitian ini pergerakan gelombang otak yang diamati yaitu pada anak autis yang disertai dengan kejang. Hasil penelitian ini menunjukkan bahwa Sebanyak tujuh Channel dari plot time series menunjukkan pergerakan yang fluktuatif di sekitar nilai rata-rata yang konstan di sepanjang waktu, sedangkan lima belas Channel lainnya menunjukkan pergerakan deret waktu yang cenderung naik turun yang tidak konstan. Tujuh Channel dari visualisasi histogram menyerupai gambar berbentuk lonceng, sehingga sebaran datanya berdistribusi normal, sedangkan lima belas Channel lainnya tidak menyerupai gambar berbentuk lonceng. Hasil monitoring pergerakan gelombang otak dengan markov switching menunjukkan bahwa gelombang otak pada anak autis mengalami abnormal di bagian otak lobus Temporal (di Channel 5 dan Channel 9), bagian otak lobus C (di Channel 16), bagian otak lobus Frontal (di Channel 8), dan bagian otak lobus Parietal (di Channel 17)

The brain is one of the most important and complex organs of the body that is owned by humans it controls all activities of the body's organs, and daily activities, and plays a role in determining emotions. If the brain is disturbed, the control of body activities will be disrupted. Therefore, an electroencephalograph (EEG) is needed, which plays a role in detecting the movement of brain waves, but in this study, the movement of brain waves observed was in autistic children accompanied by seizures. The results of this study indicate that as many as seven Channels of the time series plot show a fluctuating movement around a constant average value over time, while the other fifteen Channels show a time series movement that tends to fluctuate up and down which is not constant. Seven of the histogram visualization Channels resemble bell-shaped images, so the data distribution is normally distributed, while the other fifteen Channels do not resemble bell-shaped images. The results of monitoring the movement of brain waves with Markov switching showed that brain waves in autism children had abnormal in the Temporal lobe (in Channel 5 and Channel 9), the C lobe brain (in Channel 16), the Frontal lobe brain (in Channel 8), and Parietal lobe brain section (in Channel 17)
