Abstract

The problem in this study is the importance of the role of parents and the social environment on juvenile delinquency in Sampali Village, precisely in XIX Hamlet, Sampali Village, Percut Sei Tuan District. This research is presented using descriptive qualitative research, namely observations to explore, interview or photograph how the problem situation of the community there will be studied thoroughly and in depth. This research was conducted in XIX Hamlet, Sampali Village, with resource persons consisting of several communities in XIX Hamlet to help collect information and data for this research. From the results of observations in Hamlet XIX, Sampali Village, Percut Sei Tuan District, it is known that there are several cases committed by local teenagers, namely drugs, brawls, and motorcycle gangs. After a deeper review, the researchers found out the reason why the teenager in Hamlet XIX, Sampali Village, Percut Sei Tuan District, did juvenile delinquency, namely because the teenager had a family that did not provide love and attention, a poor social environment, and weak self-control. Therefore, the role of parents is needed, such as building good relationships, instilling faith in the heart so that it becomes a stronghold in oneself so that it is not easy to fall into actions that are not commendable. If various solutions and coaching are carried out, it is hoped that the possibility of juvenile delinquency will decrease and be resolved. From the discussion on efforts to overcome juvenile delinquency, it should be emphasized that all efforts to control juvenile delinquency must be aimed at achieving a stable, harmonious, and mature adolescent personality. Adolescents are expected to become adults with strong personalities, physically and mentally healthy, firm in belief (faith) as a society, nation, and homeland.

Abstract

This study aims to optimize the route traveled so that the transportation costs incurred by the company can be much less. This is done because the company as an agent of 3 kg LPG gas cylinders in distributing LPG gas to each base is still not optimal with irregular routes so that the costs incurred by the company are quite large. One solution that can be done in solving this distribution problem is to apply the Saving Matrix method. The Saving Matrix method is one method that can be used to determine the distribution route of a product to the area to be marketed by determining which route to take by looking at the capacity of the vehicle and the number of goods carried in order to get the shortest route and the cost for transportation incurred is small. Based on the results of the study, a distance of 100.73 km was obtained with a total initial distance of 144.29 km, with transportation costs incurred initially of Rp. 98,117.1 to Rp. 68,496.4. So, this shows that the saving matrix method can minimize distance and transportation costs.
