Everyone has a different point of view of the phenomena that occur in his surrounding environment. In this study, the phenomena being studied are the interaction between pill koplo users. The result of the study shows that there was a difference in the communication between the pills users when they were using or not using koplo pills. This statement can be seen from the way they socialized with others that had a special sign, such as stuttering, tired facial expressions, trembling body, and low intonation. Also, some things were different in koplo pills users; namely they could do heavy work without any obstacles. It happened because they used koplo pills with excessive doses. According to Lawrence Green, behavior can involve several factors, namely knowledge, attitudes, beliefs, values, and motivation. Then there are driving factors consisting of environmental and community factors. There are 3 forms of communication, namely closedform, open form, and communication behavior in verbal and non-verbal communication (Ruben & Stewart, 2013).Communication behavior can be learned through a person's communication habits. The definition of communication behavior cannot be separated from the notion of behavior and communication. The results of communication are usually related to the actions taken by someone (Effendy, 2003). Communication behavior will show the way someone achieves his communication goals, which can be seen in the interpersonal communication techniques he uses, for instance, whether he communicates properly or not, or whether he uses verbal and non-verbal communication (Effendy, 2003). Interpersonal communication itself is communication that occurs between two or more people, which are used in socializing with other people. The interpersonal communication model is divided into 3, namely linear, interactive, and rational models.
