One of the most important of adolescent development is development in social life. Indeed physical development can not be released, but most teenage cases occur because of lack of perfect social development process. Problems in adolescent social development because the teenagers have not been able to carry out the task of social development. The task of adolescent social development is a typical task of teenagers. The teenagers realize or not they have to fulfill their duty like a task at school, but on the one hand teenagers challenge to fulfill the task is so hard that the teenagers need others such as peers or classmates, family and social environment.
Peers are a very influential factor to life in adolescence. Because adolescents in modern society like today spend most of their time with their peers. In adolescence relationships with peers increased dramatically, and at the same time the proximity of adolescent relationships with parents declined drastically. Though the family is one social context that is important for the development of individuals. Although the development of children is also greatly influenced by what happens in other social contexts such as relationships with peers.
The factors that are very influential are:
• Imitation factor, which is an impulse to imitate others, for example in terms of behavior, how to dress.
• Factors of suggestion, namely the influence of psychic, either coming from himself or from others and can be accepted without any criticism of others.
• The sympathy factor, which is a feeling of attraction to others.
Peers are very important. The role of peers against teenagers is mainly related to attitude, speech, interests, appearance and behavior. Teenagers often judge that if he is wearing the same clothing model with his popular group members then the opportunity for him to be accepted by his peers. In the friendship therein there is a system and group norms that govern, such as having to mengerjai other students. This has been a mutual agreement and they are difficult to separate. Negative influence of social interaction in friendship that is very closely will occur aberrant behavior of juvenile delinquency.
Similarly, if group members try alcohol drinks, illegal drugs or cigarettes, then adolescents will follow regardless of their own feelings and consequences. This means showing that the strong influence of peers on the development of social relations and education of adolescents. Teenagers who tend to mingle with their peers who often get drunk and use drugs will be very span to follow their lifestyle. Although it has not been declared absolutely that the teen will follow the lifestyle of his friends but it should be realized that adolescence is an instability, both in thought and guiding principles of life.
With great curiosity and want to get recognition from peers. The recognized peers can influence a teenager's judgment and decisions about his behavior. Although adolescents have reached a complete stage of cognitive development to determine their own actions, adolescent self-determination in behavior is influenced by peer pressure. Peers are also able to provide a positive value in adolescents by providing information about the comparison of his identity. A good teenager who puts himself in a good peer environment can develop his or her identity toward a better or more positive.
In education, peers are found in school. Although schools do not divide the class by age and children are left to determine their own association. Peers are not only encountered in the association in the home environment but also in schools of teenage children spend a lot of time. In the association of peers in school, especially in the classroom, teenagers around smp and sma usually happens the selection of good friends who are happy and not happy. This is supported by the personality of the teenager, but whether that happens with the personality of the teenager when he entered into a loved one would have a different impact.
Teenagers are much in love by his friends will be better able to develop the attitude of social intelligence and empathetic behavior. While teenagers are excluded, he will display aggressive and implusive behavior. This means that the impact of such selection may affect the development of adolescent identity. Schools can be a facilitator: in fostering and establishing the identity of the teen through his peers. Schools can control teenagers' associations in schools, such as taking the smp realm which is a troublesome time for a teenager. But this does not mean that the school has the right to organize a teenager to get along with certain teenagers. Schools can develop a friendly attitude in the procurement of educational activities such as group learning and counseling about teenagers. At this time a teen can be positioned himself to be opposed to adult rules if he feels too organized.
Teenagers who are able to position themselves in the association of peers well can develop their identity to a better and positive. This influence is not only given to aspects of social intelligence but also touches other aspects such as emotion and cognitive. By having a good relationship with peers in the school environment and in the home environment can make adolescents comfortable to do other activities that can develop themselves. However, for teenagers who are still difficult to position themselves in the association of peers like he is not in happy or even in isolation will have an impact on the growth of hostility and will interfere with activities that can develop himself in a positive direction.
