Abstract

Introduction: The high ownership of smartphones among teenagers in Central Kalimantan, supported by increasingly widespread internet penetration, indicates the intense use of digital technology in everyday life. A national survey reveals that the majority of adolescents have a screen time of more than 3 hours per day, reflecting the dominance of screen-based activities. This condition has the potential to encourage a shift from healthy lifestyles towards sedentary lifestyles. Methods : This study is a correlational study with a cross-sectional approach in July-August 2025 involving 151 students from SMAN 2 Palangka Raya using simple random sampling. The inclusion criteria used were students of SMAN 2 Palangka Raya aged 14-17 years who had provided informed consent. Instruments used included the Screen Time Questionnaire, International Physical Activity Questionnaire, Pittsburgh Sleep Quality Index, Patient Health Questionnaire Adolescent, BMI measurement sheet, and blood pressure recording. Then, the type of data used was ordinal, which was analyzed using Somers' d, with SPSS version 25. Results: There was a significant relationship between sleep quality p (0.000 <0.05), d (-0.181), mental health p (0.003<0.05), d (0.199), and BMI p (0.032 < 0.05), d (0.161). Meanwhile, no significant relationship was found in other variables (p > 0.05). Conclusion: School-based interventions and school–parent collaboration are needed to promote balanced digital use, healthy sleep habits, and physical activity among students. This study is limited by its cross-sectional design, self-reported data, and small single-school sample, which restrict causal inference and generalizability.

Abstract

Problems in coaching novice sepak takraw athletes at the university level often lie in the lack of structured and measurable basic technique training patterns, which results in weak fundamental mastery. This study aims to analyze the effectiveness of applying systematic basic technique training patterns for sepak sila and sepak kura in improving the skills of novice athletes. The method used was a quasi-experiment with a one-group pretest-posttest design on 20 beginner athletes from the University of Palangka Raya. The research instrument was a validated skills test (Aiken's V validity > 0.80, reliability r > 0.85) to measure ball control, passing accuracy, defense, and attack. The structured training intervention was given for 6 weeks with a frequency of 3 times per week. The results of the paired sample t-test showed a significant increase in all skill aspects (p < 0.05), with an average score increase of between 16.2 and 17.2 points. The discussion relates these findings to motor learning theory, in which repetitive and gradual training strengthens motor memory and neuromuscular coordination. It is concluded that structured basic soccer and soccer training patterns are effective as a foundation for training beginner athletes.
