Abstract

Background Problems: There has not been much research on how exercise strategies affect muscle soreness and activation patterns. Research Objectives: This study examines the acute effects of rope-based functional training on muscle group pain response in student athletes at the Faculty of Sport Science, Universitas Negeri Medan tennis court. Methods: An experimental method and a pre-post-test time series design were used for analysis. Seven samples were selected using purposive sampling. All participants engaged in a warm-up, a central phase of rope training with a maximum of three sets per exercise, ten hand swing repetitions, a one-minute break between sets, and a cooling phase. Three 100-mm VAS and painometer data collection sessions were conducted. At a 0.05 significance level, the research data was examined using one-way ANOVA for normal data and Friedman for aberrant data. Both studies used SPSS 16.0. Findings and Results: The trial demonstrated that rope training induces soreness in all working muscles. However, no muscle group exhibited discomfort above 50 mm. Conclusion: In order to optimally activate muscles, determine exercise doses and blood lactate levels in relation to muscle discomfort, it is necessary to understand how battle rope training reduces muscular soreness and improves muscle activation in student-athletes on the tennis court. This understanding can inform the development of personalised training programmes and injury prevention techniques.

Abstract

Rural communities often face interrelated problems in health, education, environmental sanitation, and local economic capacity, which hinder sustainable village development. Tunong Krueng Kala Village in Aceh Besar reflects this condition, where limited access to preventive health services, low educational support for children, inadequate environmental awareness, and underutilized local potential remain key challenges. This community service article aims to describe the implementation and outcomes of a multidisciplinary empowerment program designed to strengthen community capacity through locally relevant interventions. The program was conducted through a participatory community service approach involving situation analysis, problem identification, program planning, implementation, and evaluation. The target community consisted of village residents from different age and occupational groups, while the implementing team involved university students from multiple disciplines under academic supervision and in collaboration with village authorities and local community members. The activities included blood pressure screening and hypertension education, basic literacy support for children, educational games and history learning activities, nutrition-oriented local food processing using moringa leaves, livestock health education, and environmental awareness campaigns through hygiene education and community clean-up actions. The results show that the program produced positive responses and practical benefits across several sectors. In the health activity, blood pressure screening of 24 adult participants found that only 50% were in the normal category, while the rest were classified as pre-hypertensive to moderate-severe hypertensive, indicating the importance of early detection and health education at the village level. Educational activities increased children’s enthusiasm and participation in learning, while local food processing and livestock health activities improved community knowledge and opened opportunities for household-level application. Environmental activities also strengthened awareness of hygiene and collective responsibility for village cleanliness. Overall, the program demonstrates that multidisciplinary, local potential-based community service can serve as an effective model for strengthening rural community capacity and supporting sustainable development at the village level.

Abstract

Indonesia's high vulnerability to natural disasters necessitates a collaborative disaster governance framework that engages both state and non-state actors. This study examines Muhammadiyah’s emergency response to the large-scale floods and landslides that struck Aceh, North Sumatra, and West Sumatra beginning on 26 November 2025. Adopting a qualitative case study approach, the research draws on secondary data obtained from official reports, institutional publications, credible online media, and relevant scholarly literature. The data were analyzed using thematic content analysis to identify the organizational strategies, humanitarian interventions, and governance mechanisms employed during the emergency response. The findings reveal that Muhammadiyah played a pivotal role in disaster management by mobilizing its extensive institutional network, including the Muhammadiyah Disaster Management Center (MDMC), Lazismu, hospitals, schools, universities, mosques, and local branches. Humanitarian interventions encompassed volunteer deployment, logistics distribution, emergency shelter provision, healthcare services, psychosocial support, and Islamic philanthropic fundraising. The study demonstrates that Muhammadiyah has developed a distinctive faith-based disaster governance model that integrates institutional capacity, Islamic philanthropy, social solidarity, and religious values into coordinated humanitarian action. This model strengthens community resilience while complementing government-led disaster response efforts. By highlighting the strategic contribution of a faith-based civil society organization in emergency management, this study enriches the literature on collaborative disaster governance and offers practical insights into the role of religious organizations in enhancing disaster preparedness, response effectiveness, and societal resilience in disaster-prone countries.

Abstract

This study addressed the low levels of students' learning activities, critical thinking, creative thinking, and communication skills. The study aimed to improve students' learning activities, critical thinking, creative thinking, and communication skills. A qualitative approach was employed using Classroom Action Research (CAR). The research subjects consisted of 13 fifth-grade students at SDN Pariangan, Hulu Sungai Selatan Regency. Data were collected through observations of teacher activities, student activities, critical thinking, creative thinking, communication skills, and learning outcomes. The findings revealed that teacher activity increased to a score of 36 (very good), while student activity reached 92% (almost all students were very active). Critical and creative thinking skills reached 85% (almost all students were highly skilled), communication skills reached 92% (almost all students were highly skilled), affective and psychomotor learning outcomes reached 85% (almost all students achieved very good performance), and cognitive learning outcomes reached 92% (almost all students achieved very good performance). The implementation of the LIORA learning model was proven to improve teacher activity, student activity, critical thinking, creative thinking, and communication skills in Indonesian language learning among fifth-grade students at SDN Pariangan, Hulu Sungai Selatan Regency.

Abstract

Reading literacy, communication, and collaboration are essential competencies in 21st-century learning. However, these skills among elementary school students have not yet developed optimally as expected. This study aimed to describe teacher activities and analyze the improvement of students' activities, reading literacy skills, communication skills, and collaboration skills. A Classroom Action Research (CAR) design was used in this investigation. During the second semester of the 2025–2026 school year, 14 fifth-grade children from SDN Telaga Biru 6 Banjarmasin served as the research subjects. Tests and observation were used to gather data, which were then evaluated using both quantitative and descriptive qualitative techniques. The findings demonstrated that teacher-led activities met the “Very Good” standard. Student activities improved from the category of "very few students were highly active" to "almost all students were highly active." Reading literacy skills improved from the category of "very few students were highly proficient" to "almost all students were highly proficient." Communication skills also improved from the category of "very few students were highly proficient" to "almost all students were highly proficient." Likewise, collaboration skills improved from the category of "very few students were highly proficient" to "almost all students were highly proficient." Based on these findings, it can be concluded that the PASAR model effectively improves teacher activities, student activities, reading literacy skills, communication skills, collaboration skills, and students' learning outcomes.
