Percut Village, Percut Sei Tuan District, Deli Serdang Regency is an area with the largest number of people belonging to Very Poor Households (RTSM), namely approximately 1,000 families when compared to other villages in Deli Serdang Regency. From these families, approximately 950 school-age children who have dropped out of school have not even entered formal education. The purpose of Community Service (PKM) is to be able to build a system that can help children from Very Poor Households (RTSM) to get/obtain a minimum education up to high school graduation as well as a view of the importance of health for children and families, because education and Health is a child's capital to achieve a better future. The methods used were (1) providing training and outreach to RTSM mothers, local government and also school-age children about the importance of education and health, (2) providing socialization on how to get free education (scholarships) and government assistance, (3) providing assistance in obtaining educational and health opportunities and information, educational funding assistance, learning process assistance in the form of tutoring and provision of tutoring books up to children graduating from high school, (4) Organizing RTSM mothers and study groups for routine and programmed implementation, thereby building a sustainable system.

This study aims to determine the difference in the influence between the variations of upper serve exercises using kick pads and hanging balls on the accuracy of instep service in the sport of sepak takraw. This study was conducted on students of SMA Negeri 1 Bangko Pusako who participated in extracurricular activities of sepak takraw. Problem identification showed that there were several obstacles in the accuracy of serving, such as inaccurate contact of the ball on the foot, lack of eye-foot coordination, lack of effective form of exercise, limb stiffness, and weak support when performing top serve. The purpose of this study is to prove the influence of the two training models on the accuracy of the instep service in the sport of sepak takraw. This research is expected to provide benefits for sports teachers and students at SMA Negeri 1 Bangko Pusako, especially in improving the ability to serve in the game of sepak takraw. In addition, this research can be a reference for science in the teaching and learning process as well as a reference for other researchers who are interested in the problem of service accuracy in sepak takraw. This research is expected to make a practical contribution to sepak takraw coaches in choosing more effective training methods to improve the accuracy of the instep serve, especially for students who play as tekong.

The lack of teacher creativity in testing various learning models and methods makes a significant contribution to the stigma of boredom and boredom in studying physics. The right learning model is needed so that it can help students improve learning outcomes, especially learning physics. The purpose of this study was to analyze the influence the experimental method combined with the virtual and real experiment-based guided inquiry learning model had on the physics learning outcomes. The research samples were class XI IPA 1 (32 people) for the experimental group and class XI IPA 2 (32 people) for the control group. In this study, the cluster sampling technique used was random sampling. Data collection techniques in research are in the form of learning outcomes test instruments at the beginning (pretest) and at the end of learning (posttest). The data analysis technique used is the normality test and the independent sample t-test. To test the research hypothesis, two similarity tests were used on average using the t test, namely the independent sample t-test or one-way analysis of variance (ANOVA) using the SPSS version 21 program. The result show that the guided inquiry learning model uses virtual laboratories and real laboratories to influence student learning outcomes (0.000 < 0.05). Based on the research results, it can be concluded that virtual and real experiments can improve students' physics learning outcomes, as evidenced by the difference in the average score of students' learning outcomes in the experimental class (87.47) compared to the control class (69.72).
