XYZ is a manufacturing company that produces Yamaha brand motorbike parts such as electrical switches, electrical sockets, lever assembly and horns. Many of the products sent were returned by customers because they did not meet quality standards, for example in March 2024 there were 1,420 pcs out of a total of 19,900 pcs that were returned. This means that companies have to increase production time and costs to replace defective products that are returned because they do not have safety stock. Forecasting is needed to control the production system so that it does not experience over stock and safety stock shortages. This research aims to provide recommendations for forecasting methods that companies can use to minimize the occurrence of production excesses and shortages in the company. Forecasting is done based on historical company sales data for 12 months. The method used is the exponential smoothing method which is then tested whether this method can be used in the future. This calculation uses the help of POM-QM (Production Operation Management – Quantitative Method) software. Calculations are carried out by testing the MAD, MSE, and MAPE values to obtain calculation error values. The results obtained by forecasting the main sw srtg lock assembly product using the exponential smoothing method were 15,708 for demand for the next period, MAD 3.38, MSE 22.84 and MAPE value 26%. Based on these results, the exponential smoothing method can be a recommendation for companies to forecast future demand. This is because the value of forecasting accuracy or MAPE is reasonable. The smallest percentage of MAPE values has a fairly minimal possibility of error in forecasting results.

The purpose of Indonesian national education is to educate the nation. Adolescence is a time of crisis where teenagers try to find their identity. Today, the world of education is being hit by very deep concern with the frequent occurrence of juvenile delinquency or what is known as juvenile delinquency which has quite serious impacts on the development of themselves (teenagers) and society. Because delinquency is an anti-social act, violating applicable laws, which is carried out by a person approaching adulthood with his own knowledge which if carried out by an adult is qualified as a crime. News about delinquency is sprayed like bullets on the battlefield and unfortunately the ones who are always hit by insults are the schools, in fact, it is not uncommon for the public to assume that the low quality of student behavior or personality is due to the school's inability to control the psyche of its students. In this case, we learn about what types of delinquency are carried out by teenagers, the factors that influence teenagers to commit delinquency and how schools try to overcome this delinquency. The purpose of this study was to determine the forms of juvenile delinquency, factors that influence juvenile delinquency and school efforts in overcoming juvenile delinquency. To obtain accurate data, the author uses qualitative descriptive research, namely by using the method of describing and analyzing research results without using calculation formulas, while in obtaining data the author uses direct observation, interviews with informants, and documentation. From the data obtained, it explains that the real state of juvenile delinquency (students) is still relatively common and not dangerous such as playing truant, coming late to school, not doing homework, making noise and so on. Factors that influence juvenile delinquency are often caused by lack of parental attention (broken home), the influence of playmates and from themselves because they are lazy and afraid of teachers. Then regarding the data obtained as an effort by the school to overcome juvenile delinquency (students), including cooperation with parents and the community and providing educational punishment. In addition, it also creates a commitment to all teachers to always remind every student who commits any form of violation. As a suggestion that must be done in overcoming juvenile delinquency is that parents, schools and the community should create a conducive environment, provide services and motivate teenagers to always fill their free time with positive activities. Establish interactions between students and teachers as harmoniously as possible. There needs to be self-introspection of the Teaching and Learning Activities carried out by teachers and students (teenagers). Parents are expected to pay attention to their children's daily activities and try to direct them to activities that bring benefits.

Indonesia is a country that has a lot of banana diversity. One of the banana plants that is widely found in Indonesia is the Kepok banana (Musa Paradisiaca.L).
