Abstract
The purpose of this research is to determine students’ needs in physical education learning participation. This study explores the use of learning management systems (LMS) in physical education, particularly in the implementation of the Merdeka Curriculum.
This study uses descriptive analysis methods with a quantitative approach. The sampling technique used was simple random sampling. The data collection technique involved a questionnaire containing indicators related to students’ attention, students’ desire, and the use of the learning management system, which was then applied through forms within the lms. The data analysis technique used was descriptive statistical analysis with IBM SPSS version 25.0. The reliability test results using the Cronbach’s alpha method showed rcalculated = 0.742 with n items = 15, greater than rtable = 0.227 at a significance level of 0.05. It can be concluded that  r-calculated > r-table (0.742 > 0.227).
The conclusion of this study is that the implementation of the Merdeka Curriculum in physical education using a learning management system facilitates students in submitting theoretical assignments. This research, based on qualitative methods, reveals a significant need for lms integration, including improved accessibility of materials, better interaction between students and teachers, and more effective evaluation. The Merdeka Program, introduced in 2021, emphasizes flexible project-based learning and students’ skill mastery. However, challenges include limited infrastructure and ongoing teacher training. This study also highlights the importance of lms in improving the quality of learning.

Abstract
The component of accuracy in performing a smash is one of the techniques that determine success in the game of volleyball, with the coach playing an important role in providing programs to improve athletes’ performance. This study aimed to determine the effect of resistance band and medicine ball training on the accuracy of volleyball smashes, considering the explosiveness of arm muscles in amateur athletes. An experimental method with a 2×2 factorial design and a quantitative approach was used. The subjects were 30 amateur athletes from Yogyakarta State University. Measurement instruments included volleyball smash precision tests and arm muscle explosiveness measurements using the medicine ball throw test. Data analysis was performed using a two-way ANOVA test. The results showed a significant influence of training method on volleyball smash accuracy, with F = 6.116 and p = 0.002. Arm muscle explosiveness also significantly influenced smash accuracy (F = 23.144, p < 0.001). Furthermore, there was an interaction between training method and arm muscle explosiveness on smash accuracy (F = 7.324, p = 0.003). Thus, both resistance band and medicine ball training were effective in improving volleyball smash accuracy, especially when adjusted to the explosive power characteristics of athletes’ arm muscles. This study provides recommendations for coaches to consider variations in training methods based on athletes’ physical profiles to optimize results.
