The study purpose. The online learning system, media, and resources used by lecturers to achieve volleyball learning goals are known to be not optimal. This study aimed to develop an e-learning video media that can be used by students as a learning resource to learn the material for upper serve, jump serve, and floating serve in volleyball games. Materials and methods. The research subjects were students who were divided into treatment groups and control groups where each group consisted of 40 people. The research method used was an experimental method with a before-after research design (one-group pretest and posttest design). A rubric test is an instrument used to measure the effectiveness of video media in improving student service skills. Results. The results of the research and data analysis found that the service skills (upper serve, jump serve, and floating serve) in the treatment group with the help of e-learning video media were better than in the control group who did not receive e-learning. Conclusions. The treatment group has better service skills than the control group. During the Covid-19 pandemic, it is recommended for lecturers to use e-learning video media in teaching volleyball service material.

This study aims to determine the difference in the effect of small sided games and drill on passing accuracy and VO2Max in soccer games. This research is using experimental method. The sample in this study is 26 people, then divided into two groups using matching by fairing techniques. The results of this study, namely the first hypothesis obtained t-hit of 6.96 and t-table 1.78, then (6.96> 1.78) Ha is accepted and Ho is rejected. The second hypothesis is obtained t-hit of 4.98 and t-table 1.78, then (4.98> 1.78) Ha is accepted and Ho is rejected. The third hypothesis is obtained t-hit of 13.01 and t-table 1.78, then (13.01> 1.78) Ha is accepted and Ho is rejected. The fourth hypothesis is obtained t-hit of 5.79 and t-table 1.78, then (5.79> 1.78) Ha is accepted and Ho is rejected. The fifth hypothesis is obtained t-count 3.063 and t-table 1.71 (3.063> 1.71) and (0.005 <0.05) then Ha is accepted and Ho is rejected. The sixth hypothesis is obtained t-count 3,971 and t-table 1,71 (3,063> 1,71) and (0,001 <0,05) then Ha is accepted and Ho is rejected. The conclusion of this study is, There is a significant effect of the small sided games training method on improving passing accuracy. There is a significant effect of the drill training method on increasing passing accuracy. There is a significant effect of the small sided games training method on increasing VO2max. There is a significant effect of the drill training method on increasing VO2max. There is a significant difference in the effect of the small sided games training method with the drill on improving soccer passing accuracy. There is a significant difference in the effect of the small sided games training method and the drill training method on increasing VO2Max.

This research aims to know the common mistakes made when doing a lay up shot in the game of basketball. Analysis of lay up shot is very necessary for the coach or instructor and basketball player itself to figure out how to fix the error. Analysis of lying Shot started, step (1. Reflecting sphere of the Agency towards the ring, 2. Forward with the right foot), jump (jump using the left foot), shot (1. Insert the ball with your right hand, 2. Thighs lift your right leg, 3. Head the ball to the target on the reflection). The number of samples as many as 35 people, who came from rookie basketball player i.e. students aged 17-19 years. The results of this research are (1) stepped on stage just as much as 44.3% to successfully perform the phases correctly. (2) at the stage of jumping as much as 77.1% to successfully perform this stage well and (3) on the stage of entering the ball just as much as 41% who succeed do the phases correctly.

The purpose of this research is to produce a new product in the form of censorship media and video assistant referee (VAR) in assisting referee leadership in a championship to achieve fair play. This research uses the Research and Development (RD) method from Sugiyono using ten steps. The place of research was carried out at the All-Indonesian Volleyball Association, Deli Serdang Regency. The population and sample in this study were 36 Deli Serdang Regency volleyball players with a small sample of 6 people, a large sample of 16, and a comparison sample of 14. For the referee sample, six nationally licensed and nine regional licensed referees. The results of this study include Net and VAR sensors used to develop a player error detection tool when smashing and blocking. The results are obtained from the data from expert validation, including: (1) Material experts 92.3% with the "Very Eligible" category. (2) Media Experts 92.5% with the "Very Eligible" category. In large-scale trials on referees and athletes, the resulting percentages were 90.8% and 92.7%, respectively, while in the comparison trial, the percentage produced was 92.5%.

Abstrak-The purpose of this study was to find out how the implementation of physical education learning in mentally retarded students at YPAC Medan Special School (SLB). The method used in this study uses a qualitative approach. The subjects of this study were physical education teachers and mild tuna students. Data collection techniques using observation and interview data. Based on the results of research found that students are still undeveloped from the educational process such as students who have not been able to read, the teacher does not have a special background education which makes it difficult for teachers to teach mentally disabled children, and teachers should have a special teacher in implementing learning. The conclusion of this study is that the creativity of physical education teachers is very much needed in making learning that stimulates the development of student and motoric knowledge of students, the selection of activities for learning physical education is still difficult to determine by physical education teachers. This is due to the condition and situation of mentally disabled children who every day are difficult to predict. Therefore physical education teachers must pay attention to children's intellectual, social and emotional levels.

This research used experimental design in the form of one group pre-post design, aimed to find out; the effect of hypnotherapy on fostering athletes' achievements in jump and throw sports. The population was all athletes in the athletic sport of jumping and throwing of 23 people. The technique of determining the sample by positive sampling, while the technique of data analysis used descriptive frequency analysis and paired sample test analysis (paired t-test) through the SPSS program version 20.00 at a significant level α = 0.05. The results showed that "the influence of hypnotherapy on fostering athlete achievements in jump and throw sports, t-test values of t-count of 2,354 and t-table (22; 0.05) of 1,717 with a significant level of 0.028 (0.028 < α = 0.05) or (t_count> t_table) The conclusion of this study was there is an influence of hypnotherapy on fostering athlete’s achievement suggestibility (tance level test) in jump and throw of athletic sports.
