Abstract

Physical activity is something that cannot be separated by human life, especially in the scope of education. Sports become a necessity, in this sport get benefits including to improve, both physical health, mental health (Fauzan, 2021:154) (Fauzan A, 2021: 154)  Currently, humans are spoiled by the existence of technology that is increasingly rapid, the existence of technology that is increasingly developing and sophisticated provides facilities that are easily enjoyed by humans. In study aims to develop an application product that can be used to increase physical activity for students. Referring to the development of Borg and Gall, namely research and development research using learning experts and application media experts, learning experts gave an assessment of 93% and learning media experts gave a score of 100% with very good meaning, worth using. This small group trial used 32 respondents and used 16 questions with 79% results, with a good category, worth using, an increase in pulse rate of 22%. The large group trial used three schools with 87% results, an increase in pulse rate of 24%, the conclusion is that the product can increase physical activity. This developed product will be able to be used easily to assist classroom learning in junior high school.

Abstract

This study examines Rivan Nurmulki’s jump serve motion during the men’s volleyball final at the 2025 SEA Games in Thailand. This study is based on the importance of the serve as an offensive technique in modern volleyball, as it can influence point scoring and the momentum of the match. The objective of the study is to compare the movement characteristics of failed and successful jump serves based on biomechanical indicators. The method used is quantitative descriptive, with data consisting of match recordings from YouTube. Analysis was conducted using Kinovea to measure the approach distance, stride length, body angle, jump height, ball reach height, and ball speed. The results of the study indicate that successful jump serves exhibit more optimal movement patterns compared to failed serves. For successful serves, the approach distance was 471.75 cm, the first step was 107.46 cm, the second step was 139.85 cm, the jump height was 123.96 cm, the ball reach height was 387.89 cm, and the ball speed was 16.73 m/s. The success of the jump serve is influenced by the coordination of the approach, takeoff, body position, point of impact, and arm swing, making it a benchmark for evaluation by coaches and athletes.
