Recognizing Parents Emotions through Heart Beat Sensors as Prevention Efforts Parents Violence toward Children

ABSTRACT This research is a collaboration between psychology and electronics engineering. This study aimed to detect emotions through the heart rate by using a heart beat sensor. The study was conducted using five subjects aged between 20-23 years. The procedure of the study was carried out through two steps. In the first step, the five subjects did not carry out any strenuous activities for five minutes and then measured their heart rate. The second step, the subject was asked to watch a horror movie and then measured his heart rate again. The experimental process is at the fingertips of the subject put a heart beat to get the heart rate sensor. The LED light that penetrates the fingertip is received by the Receiver Circuit and then processed into a digital data by the Arduino Uno microcontroller. Data that has been received by Arduino was forwarded through software processing to display the output on a computer screen. The output on the computer screen shows the condition of a person's heartbeat. Emotions and heart rate are interrelated. Emotions involve a variety of accompanying physiological experiences, for example the speed of the heart. The faster the heart rate, the person is in an emotional state. Emotions are formed by a part of the brain called the limbic system. Parental violence against children that occurs when emotional conditions are driven by the autonomic nervous system and limbic system. Violence is a form of physiological reaction from emotions. The results showed that there are differences in heart rate between relaxed conditions and emotional conditions. Emotional condition heart rate is ranging from 100 to 140 Beat PerMinute (BPM) and relaxed conditions is ranging from 60 to 90 Beat PerMinute (BPM). This is because the heart pumps blood faster.
