Abstract. "Teenager", a word that contains many kinds of impressions. Some people say that teenagers are a normal group, no different from other social groups. While some other parties consider teenagers as a group that often causes difficulties for parents. In addition to this opinion, there are also those who argue that youth is a potential that needs to be utilized. (Mappiare, 1982). However, the opinion of teenagers about his personality, then they will show a different impression. Some of them may speak of adults' indifference or indifference to their group. There are also those who will give the impression that their group is a minority with their own "world" and cannot be touched by their parents. Based on the impressions presented, it is very important that teenagers are a potential group to work with. This is because youth are a group that has responsibility for the nation and the future. In fact, in Indonesia, adolescent make up about a third of the total population. Especially in their youth, they have great vitality and patriotism. Thus, youth are the successors of the nation's hope. (Mappiare, 1982). Teenagers don't really belong. They are no longer included in the children's class, but are not yet fully accepted into the adult class. Adolescents are between children and adults. Therefore, adolescence is often called the period of "identity search" or the period of "storm, storm". However, adolescence is a developmental period that is currently in the potential of childhood, both cognitively, emotionally, and physically. (Hartinah, 2008). The rapid intellectual development of adolescents in the way of thinking allows them to integrate into adult society, but it is also the most prominent feature of all periods. Continuity of intellectual development makes teenagers able to think formally. This stage allows teens to think more abstractly, test assumptions, and consider the opportunities available to them rather than just seeing them for what they are. Intellectual ability like this is what distinguishes youth from previous times. In addition, the development of certain talents or interests among adolescents also begins to order and begins to decline based on factors that affect both themselves and their environment. All teenagers more or less have certain special interests that include various types. Intellectual development and special talents or interests are part of cognitive development that occurs in adolescents. This cognitive development affects a person's way of thinking, analyzing a problem, and a person's preferences for certain things.
