Abstract:
Drug use in Indonesia tends to be increasingly out of control where the number of users continues to increase every year. The dangers of drugs can cause various adverse effects, including psychotic behavior, convulsions, and even death due to overdose. The most dominant part disturbed by drugs is the frontal lobe of the brain, one effect is the reduced concentration of the user. To minimize this addiction, therapy with methadone (a synthetic drug to replace opioid drugs) is used. In this paper, an experiment with therapeutic patients to detect changes in brain wave amplitude due to methadone administration was carried out. EEG data recording of each subject is done using an EEG system with 19 channels. To stimulate the change in amplitude, each subject is given a stimulus that is by displaying several random images on a monitor. Each of them consists of 4 images similar to drugs referred to as non-targets and 1 image of drugs called targets. In one session all images will be displaye
d randomly for 10 turns (a total of 20 seconds). To minimize interference or artefacts on the recording, the data is filtered by bandpass (0.5-70 Hz) and wavelet, respectively. From this experiment it was found that significant changes in brain wave amplitude after methadone intake were obtained. These results indicate that the use of methadone is very influential on brain wave activity. The decrease is part of the reduced level of desire to consume drugs.
