Abstract - The study aims to test the effectiveness of storytelling life mapping as a way to reduce aggressive behavior in adolescents. The

study participants were 110 participants aged 12-15 years who had aggressive behavior in school. Eight sessions of storytelling life

mapping applied for 60 minutes / session. The research design used is Pretest Posttest Control Group Design. Measuring tool used the

scale of aggressive behavior of adolescents. The comparison of the effectiveness of storytelling of life mapping for the control group and

the experimental group was significant, indicating that the aggressive behavior of adolescents decreased.

Subsequent trials descriptive analysis, norms are made based on Standard of aggressive behavior scale were conducted on March 12, Error (SE) considerations in the measurement. This is done 2018, where preliminary measurements were given to 140 because researchers only divide the participant into two participants to see some items omitted and used in pretest categories, namely medium and high (Azwar, 2009).

  7 This training facilitator is a researcher who conducts this intervention. The training was conducted in a large group of 55 people. The training also consists of 3-4 observers who are in charge of assisting the facilitator to observe each participant. Aspects of considerations in the selection of facilitators are as follows:

  • Experienced in group training, especially groups of children
  • Has undergraduate education
  • Understand the issues of aggressive behavior - Willing to intervene in training for 8 days in Takengon.

  This intervention was conducted for eight sessions with a duration of 60 minutes at each session and then given approximately one week from the eighth session to take post test data.

  Quantitative data processing is done by using SPSS program for windows 20.0 version. Data analysis technique used is statistical analysis of parametric T-test.

  Similarly, another factor that plays a significant role in the regulation of emotions by adolescents is to increase sensitivity that increases self-awareness. At this stage adolescents also describe themselves as if in front of an imaginary audience who record and evaluate every action

  In addition to anger there are some behavioral experiences that fall into the aggressive category that is mocking, hostile, insulting, punching and the most extreme is killing. Research participants are adolescents aged 12-15 years at this time according to Zeman (2001) in the development of emotions, a period where individuals already have the ability to manage emotions and has been able to develop a vocabulary that is enough to be invited to discuss that can affect the emotional state of self and others.

  Storytelling this life mapping helps the participant to see how should the behavior appear in certain conditions. In the activity of activitis III the participant is directed to life situations that are similar to the life character of the participant. While IV activity reveals about self participant more special to know level of creativity better participant and free participant in exploring her/himself.

  Some of the things that influence the success of the research are the intervention done in the group. The implementation of storytelling of life mapping in groups is a factor that supports the effectiveness of storytelling life mapping in decreasing aggressive behavior of the participant. Through paper activity sheet II, the participant can know each other how people around in expressing anger, and know the form of anger that appears in others.

  Also proven in this study storytelling therapy life mapping (creative writing method) effective in reducing aggressive behavior in the junior class population. In the experimental group, aggressive behavior decreased significantly after training and also after follow-up. In addition, it shows behavioral changes in the participant of research after being given therapy, and qualitatively storytelling can be an alternative as a medium for students to express ideas, emotions, and experiences perceived.

  In activity I participants are invited to understand the content and learning experience of the story content. The participant must be able to identify the problem in the story so that the participant can respond to the problem and give an opinion to solve it.

  This therapy also focuses on important relationships in a person's life to help deal with problems, such as honesty, courage, and improve attitudes to be more positive by using the method of reading stories with teacher centered and writing methods.

  Things that affect the success of this intervention are applied by involving the participant in the activity as well as interacting in its entirety, with the teacher centered method, listening to the story, writing the participant's feelings in the activity sheet.

  Intervention storytelling life mapping designed in this study aims to reduce aggressive behavior in adolescents. After the storytelling intervention of life mapping was given, the result of aggressive behavior decreased in junior high school "X". The decrease in aggressive behavior in adolescents is evidenced by T-test statistical analysis, with p = 0.001 (p &lt;0.05). This shows that there are differences in behavior in the experimental and control groups.

  It is known that the F-statistic value for the assumption of variance is 0.634 with probability (p&gt; .428). In conclusion that probabilias (p.428&gt; .05) then HO is accepted, then the storytelling of life mapping is effective. Thus, the t-test refers to the values on the same basis of variances. The t-statistic value of aggressive behavior is -

  they take. Thus, adolescents become very aware of the impact of their emotional expression on social interaction.

  Repeating the material given each time the execution is considered effective enough. Implementation of the intervention to know the extent to which the participant understands the session that has been implemented, and decide whether to continue to follow the next activity. Beck (2011) explains that repetition or review is helpful in the therapeutic process. For the therapist, this serves to see how far the participant has understood the therapeutic process, while for the participant, it serves to help recall the various information that has been received. The same thing happens in the training process where the facilitator plays a therapist while the participant is the a subject.

  Furthermore, the effectiveness of the storytelling of life mapping is the participant of applying the ability through writing about the lives of others and recognizing themselves through judgment and writing about the environment and anger. Participants can see what behaviors appear to cause emotions.

  Also in this study also with the game before intervening so that the participant was happy. It is beneficial for the participant to recognize, express, and control the perceived emotion. The game consists of a series of games that involve collaboration, generating emotion, so the participant can start friendship and communication with their peers.

  In addition from the results of the study showed after the implementation of interventions aggressive behavior decreased. This may occur due to the influence of conformity. Conformity occurs when the individual adopts the behavior or attitude of another person (coerced into real) or not (Santrock, 2007). The participant's desire to engage in aggressive behavior is the desire to follow a friend who is reducing his aggressive behavior.

  Based on the results of quantitative analysis in this study can be concluded that the hypothesis of this study accepted which means that storytelling life mapping can reduce aggressive behavior of adolescents in SMP X Takengon. This result is obtained from parametric analysis of T-Test with p value = 0.001 (p &lt;0.05). This means that there is a difference in the decrease of aggressive behavior in the experimental group and control group after given the storytelling of life mapping.

  Suggestion

  a. For experimental studies related to storytelling life mapping, it is necessary to consider the number of participants (N = 55), so it is easy to control the implementation.

  b. For the next research it is better to add qualitative data per individual to sharpen the results of the study.
