This study focused on the impact of Arabica coffee on the concentration of Beta waves of individuals. This was done by measuring and how the Arabica coffee affects Human EEG Frequency. Local Arabica coffee from Chiang Rai, Thailand was adopted in this study as a medium to wake up the human brain wave (attention). The experimental result showed that coffee can make human brain wave (attention) increase. The study conducted on fifty participants: twenty-five males and twenty-five females aged between twenty to thirty years old. The Electroencephalography (EEG) is collected twice and compared. The effect of caffeine on human brain waves was measured using NeuroSky Mindwave mobile. The paired sample t-test was employed for comparing two groups Beta brain waves collected in the experiment. The K-means algorithm was used to perform data mining on brain waves, and the differential brain wave signal data is clustered and divided into three levels. The experimental results showed that there was a statistically significant difference between the two paired samples. Therefore, the results confirm that coffee has a direct impact on personal Beta waves.
