Abstract

ABSTRACT This study aims to develop the SmartFit Kids application as a physical fitness education medium that integrates traditional Karo games for elementary school students. With the increasing use of digital technology and decreasing children's interest in physical activity, innovations that combine technology with local wisdom are needed. This application was designed using the Research and Development (R&D) method with a user-centered design approach on 24 fourth-grade students from SD Swasta Masehi 1 Kabanjahe, Karo Regency. The validation results by media experts obtained a percentage of 82% with a feasible category, while the validation results by material experts also showed a percentage of 82% with a feasible category. Furthermore, product trials on research subjects obtained a percentage of 80%, so that overall this website application was declared suitable for use as a physical education learning medium based on traditional games. Conclusion, this application successfully preserves local Karo culture while meeting the needs of modern physical education with measurable effectiveness.

Abstract

This study was motivated by the importance of lower-limb explosive power in volleyball, particularly in supporting smashing, blocking, and jumping serves, while evidence regarding the effectiveness of box jump training among male extracurricular participants at SMP Siempat Teran Naman remains limited. The study aimed to analyze the effect of box jump training on the lower-limb explosive power of male volleyball extracurricular participants at SMP Siempat Teran Naman using an experimental method with a one-group pretest-posttest design. The subjects were 15 participants aged 13–15 years selected through total sampling, who underwent box jump training for four weeks at a frequency of three sessions per week, with lower-limb explosive power measured using the Vertical Jump Test before and after training. The results showed that the average explosive power increased from 41.40 cm to 49.80 cm, while the paired-sample t-test produced a t-value of 14.21 > t-table of 2.145 with a significance value of 0.000 < 0.05, indicating a significant difference. These findings demonstrate that structured and progressive box jump training can serve as a practical alternative for improving lower-limb explosive power while supporting volleyball development in schools.

Abstract

This study aimed to determine the effect of paired passing training on the underhand passing skills of students at SMP Negeri 1 Berastagi in the 2025/2026 Academic Year. The research employed a quantitative experimental method using a One Group Pretest-Posttest Design. The population consisted of 32 students, while the sample included 14 students selected according to the research requirements. The instrument used was an underhand passing skill assessment sheet covering initial stance, passing execution, ball direction and control, cooperation, and consistency. Data were analyzed using normality tests, homogeneity tests, and hypothesis testing through the Paired Sample t-Test. The results showed that the average score of students' underhand passing skills increased from 51.7 in the pretest to 68 in the Posttest, with an average improvement of 16.3 points. The normality test indicated that the data were normally distributed, with significance values of 0.196 for the pretest and 0.198 for the Posttest. The homogeneity test produced a significance value of 0.898, indicating homogeneous data. Furthermore, the hypothesis test using the Paired Sample t-Test showed a significance value of (p < 0.05), meaning that the alternative hypothesis (Ha) was accepted and the null hypothesis (Hâ‚€) was rejected. Therefore, it can be concluded that paired passing training had a significant effect on improving the underhand passing skills of students at SMP Negeri 1 Berastagi in the 2025/2026 Academic Year.
