The Society 5.0 era demands increased student health literacy as an essential competency. However, previous research has tended to focus only on the health education aspect and has not comprehensively examined the integration of technology-based health education management. Therefore, this study aims to analyze the effectiveness of technology-based health education management innovations and identify key factors influencing their successful implementation. This study used a mixed methods approach with a sequential explanatory design. Quantitative data were collected through a survey of 200 students, while qualitative data were obtained through in-depth interviews with 10 teachers and the principal. Quantitative data were analyzed using descriptive and inferential statistics, while qualitative data were analyzed using a thematic approach to strengthen the interpretation of the results. The results indicate that technology-based health education management innovations have a significant impact on improving student health literacy. Furthermore, it was found that successful implementation is influenced by five main factors: school institutional support, availability of technological infrastructure, teacher training, student motivation, and parental involvement. The novelty of this research lies in the integration of managerial and technological approaches in health education, tested through a mixed methods approach. These findings confirm that successful health literacy improvement is determined not only by the use of technology, but also by organizational readiness and multi-stakeholder collaboration. The implications of this research provide theoretical contributions to the development of technology-based health education management models and practical recommendations for educational institutions facing the challenges of Society 5.0.

The rapid development of the digital era has significantly impacted adolescents by increasing academic stress due to academic demands, performance pressure, and technological distractions. This condition is often exacerbated by low levels of emotion regulation, which negatively affect students’ learning focus and psychological well-being. Therefore, effective interventions are needed to help students manage their emotions adaptively. This community service program aims to enhance emotional balance and reduce academic stress through a mindfulness-based intervention at MA Plus Nururrohmah. The program employed a participatory approach with stages of preparation, implementation, and evaluation. It was conducted in two main sessions: a mindfulness session delivered by Erlin Kurnia Sri Rejeki, M.Pd.I, and an interactive stress-release session facilitated by Estria Solihatun Nurjannah, M.Pd. Data were collected qualitatively through observation, documentation, and analysis of students’ responses and participation. The results show improved emotional awareness, better recognition of stress conditions, and increased student engagement. Additionally, students demonstrated more positive emotional states after the program. Thus, mindfulness implementation contributes positively to enhancing emotion regulation and reducing academic stress and has potential as a sustainable school-based mental health intervention model.

This study is grounded in the observation that online game addiction has emerged among learners at SMP Muhammadiyah Bantul. In the present digital era, playing games through the internet has become tightly woven into adolescents' everyday routines. Easy accessibility together with the broad spectrum of entertainment provided has pushed the popularity of online games upward. However, immoderate engagement may foster addictive patterns that adversely affect students' academic performance, social interaction, physical condition, and mental well-being. Hence, a workable intervention is required to lower the level of dependence. The purpose of this research is to decrease learners' online game addiction by means of group counseling services that draw on the Cognitive Behavioral Therapy (CBT) framework combined with cognitive restructuring techniques. A one-group pretest-posttest experimental scheme was adopted in this work. The findings reveal a notable reduction in the students' online game addiction scores, evidenced by the paired sample t-test significance value (two-tailed) of 0.000, which falls below 0.05. It can therefore be inferred that group counseling rooted in the Cognitive Behavioral Therapy approach with cognitive restructuring techniques is effective for reducing online game addiction in seventh-grade learners at SMP Muhammadiyah Bantul.

Due to its effect on the caliber of generations to come, iron deficiency anemia in teenage females is one of Indonesia's most pressing reproductive health concerns. Adolescents' awareness to autonomously adopt preventative actions is shaped mostly by their knowledge. The purpose of this research is to determine whether there is a correlation between the prevalence of anemia among teenage females in Boyolali Regency and their degree of education. Using a cross-sectional design, this study employs quantitative correlational analytic methods. An accidental sampling approach was used to obtain a sample size of 80 respondents from the population of seventh grade female pupils. A digital POCT device was utilized to quantify the incidence of anemia variables based on hemoglobin (Hb) levels, while a structured questionnaire instrument was employed to gather data for knowledge variables. The Chi-Square test was used to assess the bivariate data analysis. According to the univariate analysis, 62.5% of the participants (50 respondents) had a decent level of knowledge, and 73.8% of the participants (59 respondents) did not suffer from anemia (Hb > 12 g/dL). With a p-value of 0.000 (p < 0.05), the results of the bivariate test were generated. Anemia is more common among female students at MTs Al Ihsan Doglo who have a higher degree of expertise, according to this study. School districts should keep an eye on students' iron pill use and improve their nutrition education programs.

This study aims to analyze the effect of homework load and extended study hours on students’ learning stress levels. The background of this research is based on increasing academic demands that may affect students’ psychological conditions. This study employs a qualitative approach with data collected through observation and interviews. The results indicate that excessive homework load and prolonged study duration significantly contribute to higher levels of learning stress. Students tend to experience physical and mental fatigue, decreased motivation, and difficulty managing time between study and rest. In addition, pressure to achieve high academic performance further exacerbates stress levels. Other factors such as lack of environmental support and less varied teaching methods also influence students’ stress. Furthermore, students often report feelings of anxiety and emotional exhaustion when academic tasks accumulate without adequate rest periods. This condition not only affects their psychological well-being but also reduces concentration and learning effectiveness in the classroom. Therefore, balanced learning load management, appropriate task distribution, and more effective and humanistic teaching strategies are needed to reduce learning stress and improve the quality of education. Schools and educators are encouraged to consider students’ cognitive capacity and mental health in designing assignments and study schedules to create a more supportive learning environment.

A common health problem, especially in developing countries, is anemia. This is common among adolescent girls due to their lack of knowledge about anemia. This puts them at risk of developing anemia, particularly because menstruation is a contributing factor. Providing health education is expected to change behaviors toward a healthy lifestyle and contribute to preventing anemia among adolescent girls. This community service activity was held on May 26, 2026, at SMK Bhakti Indonesia Medika, and was attended by female students of childbearing age. The methods used included lectures, discussions, question-and-answer sessions, and sharing sessions. Pretests and posttests were used as evaluation materials to measure the increase in students' knowledge. The average pretest score was 7, while the average posttest score was 12, indicating a 5 point increase in knowledge about anemia among adolescent girls. The students demonstrated interest and enthusiasm during this activity. The results and conclusions of the e-booklet-based education program proved to be an effective alternative medium for increasing students' knowledge about anemia prevention. It is hoped that similar education can be implemented sustainably to improve the quality of healthy life in adolescent girls.

Substance and prescription drug misuse among adolescents continues to escalate and demands targeted preventive strategies within the school setting. This community service activity aimed to enhance students’ knowledge about the hazards of drug abuse through an interactive, school-based educational intervention. The program was conducted on 11 November 2026 at SMA Negeri 7 Kota Batam, involving fifty grade-X students as participants. A pre-experimental one-group pretest–posttest design was employed. The intervention combined interactive lectures, real-case illustrations, and two-way discussion, with knowledge measured using a content-validated questionnaire covering ten indicators. The mean score improved from 55.2 (pretest) to 86.3 (posttest), a gain of 31.1 points, while the proportion of correct answers across indicators rose from 48.6-62.9% to 80.0-91.4%. The largest gains appeared on items concerning rational drug use and the importance of professional health guidance, whereas the legal-consequence indicator improved more modestly. Interactive, contextually relevant education proves effective in elevating adolescent knowledge of drug abuse hazards, with stronger gains on experience-near content than on abstract regulatory aspects.

This community service study documents and analyzes a blood glucose screening program conducted by theology students of STT Kadesi–Bogor at the Pentecostal Church (Gereja Pantekosta Jakarta/GPJ) in West Jakarta from February to April 2026. A total of 80 examinations were performed over three consecutive months using the Accu-Check glucometer. Results revealed that 1 participant (1.25%) was classified as diabetic (random blood glucose/RBG ≥200 mg/dL) and 19 participants (23.75%) were classified as pre-diabetic or at elevated risk (RBG 126–199 mg/dL), bringing the total at-risk proportion to 25%. The mean participant age was 52.7 years (range: 21–82 years). Women constituted 78.75% of all participants and accounted for 70% of at-risk cases, while men showed a proportionally higher per-capita risk rate (35.3% vs. 22.2%). Five female participants recorded borderline-low glucose levels (70–75 mg/dL), indicating potential nutritional inadequacy. This study contextualizes its findings within biblical theology—particularly 1 Corinthians 3:16, which declares the human body to be the temple of the Holy Spirit—providing a theological imperative for holistic health stewardship. Practical recommendations include adoption of a balanced diet, engagement in regular physical activity, and periodic blood glucose monitoring as expressions of faithful bodily stewardship.
