Development and evaluation of an Android-based multimedia application to promote healthy lifestyles in physical education: A study at State Junior High School 29 Semarang
Galang Yusuf Pujiyanto1, Ibnu Fatkhu Royana2, Muh. Isna Nurdin Wibisana31. Universitas PGRI Semarang , ID2. Universitas PGRI Semarang , ID3. Universitas PGRI Semarang , ID2025-07-23|page 162-174AbstractBackground: The integration of interactive, technology-based media in Physical Education, particularly for teaching health-related content, remains limited despite its potential to enhance student engagement and learning outcomes.
Objectives: This study aims to address this gap by developing and evaluating the effectiveness of an Android-based multimedia learning application, "Healthy Habits," designed to support the delivery of healthy lifestyle materials in Physical Education, Sports, and Health (Physical Education) subjects at the junior high school level.
Methods: The research employed a research and development (R&D) approach, involving expert validation from media and content specialists and usability trials with teachers and students.
Results: Validation results indicated a "Good" rating from the material expert (average score: 4.05) and a "Very Good" rating from the media expert (average score: 4.24), confirming the application's content quality and technical feasibility. Teacher evaluations also yielded a "Good" rating (average score: 4.07). Student trials produced positive responses, with small group testing receiving a "Very Good" rating (average score: 3.29), which increased to 4.23 ("Very Good") in large group testing. An effectiveness test assessing cognitive, affective, and psychomotor learning outcomes showed an average score of 85.6%, categorized as "Very Good." These findings demonstrate the feasibility and effectiveness of "Healthy Habits" as a digital learning tool for promoting healthy lifestyles in secondary school students.
Conclusions: The application offers practical value for educators and curriculum developers seeking to integrate mobile technology into Physical Education. Future studies are encouraged to explore the implementation of this application in varied educational contexts and its potential integration across other subject areas.

The association between healthy dietary habits and physical fitness among junior high school students: A rural school case study
Moch. Yunus1, Yulingga Nanda Hanief2, Muhammad Putra Ramadhan3, Erika Ayu Sylvianingrum41. State University of Malang , ID2. State University of Malang , ID3. State University of Malang , ID4. State University of Malang , ID2025-12-30|page 344-354AbstractBackground: The health conditions of the community, particularly in relation to the physical fitness of junior high school students, require serious attention, especially in rural areas that differ significantly from urban areas. Previous research findings on dietary patterns and physical fitness still show inconsistent results.
Objectives: This study aims to investigate the relationship between healthy eating habits and physical fitness among junior high school students residing in rural areas.
Methods: This study used a quantitative design with a cross-sectional approach. The research subjects consisted of 27 students from public junior high schools in rural areas, selected through a balanced stratified random sampling process that involved all grade levels. Eating habits were measured using a 24-hour food recall, as it is an effective method for monitoring food intake over a short period. Physical fitness was measured using the Nusantara Student Fitness Test (TKPN), a national standard instrument. Data analysis was performed using descriptive statistics, Spearman's correlation, and linear regression.
Results: Most of the study participants were underweight with varied eating patterns. The analysis results showed no significant relationship between physical fitness and healthy eating patterns, as indicated by a correlation coefficient of 0.061 and a p-value of 0.764. The small effect size suggests that eating patterns did not have a significant impact on fitness levels in this group of participants.
Conclusions: The study shows that rural junior high school students achieve their physical fitness through exercise and their exercise-rest patterns and their inherited characteristics rather than their diet.APA Citation StyleYunus, M. , Hanief, Y.
