The community service program titled Great Youth, Strong Mentality at Untung Suropati Catholic High School aimed to enhance students understanding and skills in managing stress and anxiety, which are increasingly prevalent among adolescents due to academic pressures, social dynamics, environmental changes, and excessive exposure to social media. These issues are exacerbated by a lack of knowledge about effective stress management strategies, such as relaxation techniques and emotional communication, as well as the stigma surrounding mental health that discourages adolescents from seeking help. The counseling was conducted using an interactive approach, comprising a 30-minute informative lecture to explain the concepts of stress and anxiety, small group discussions (5–7 students) to encourage reflection and sharing of experiences, and practical exercises on relaxation techniques, such as diaphragmatic breathing and mindfulness, to provide hands-on experience. Supporting materials, including visual presentations and interactive quizzes, were utilized to enhance student engagement. Post-event evaluation revealed significant improvements in the understanding of stress and anxiety among students in grades X, XI, and XII. Students demonstrated enthusiasm through active participation in discussions and practical sessions, as well as positive feedback on the supportive and stigma-free environment. The program successfully equipped students with practical skills for stress management and fostered a healthier learning environment. For sustainability, it is recommended to conduct similar programs regularly, integrate mental health education into the school curriculum or extracurricular activities, provide concise modules for students’ independent use, and collaborate with school counselors to monitor technique implementation and offer ongoing support to ensure long-term impact on students mental well-being.

This study aims to systematically review the literature that discusses the influence of social media on adolescent communication patterns, especially in the context of organizational learning. Social media as part of the digital transformation has changed the way adolescents interact, not only in social aspects but also in informal learning processes. Through a Systematic Literature Review approach, this study maps key concepts, identifies research gaps, and explores future research directions. The results of the study indicate that social media plays an important role in shaping interpersonal communication, digital ethics, and adolescent self-identity. However, most previous studies are still geographically limited, descriptive, and have not linked social media use to organizational learning comprehensively. Therefore, it is necessary to develop an integrative theoretical model and longitudinal studies that consider the cultural, psychological, and social contexts of adolescents in the digital era.

This paper discusses the study of politics from an Islamic perspective, which not only examines power and governance but also serves as a foundation for the development of political ethics rooted in the spiritual and moral values of the Qur'an and Hadith. The approach used is a literature review, analyzing relevant texts on Islamic politics, political ethics, and leadership concepts in Islam. In Islam, politics is regarded as a form of worship that must be carried out based on the principles of tawhid (monotheism), justice, shura (consultation), and social responsibility. Concepts such as khalifah (caliphate), shura, and maslahah (public interest) serve as key pillars in the ethical governance system aimed at the welfare of the ummah (community). Furthermore, this paper highlights the importance of political morality (akhlaq siyasah) as a moral foundation for leaders and political actors, while also exploring the distinction between ethics (akhlaq) and morality in the Islamic context. The findings indicate that integrating political studies with Islamic values can create a model of governance that is not only structurally strong but also morally and spiritually elevated. Thus, Islam offers a holistic normative framework for building a just and civilized political system.

This study aims to examine the effectiveness of the demonstration method in improving the understanding of the concept of force in grade 1 elementary school students. The approach used is a literature study by reviewing various current scientific sources from 2021 to 2025. The results of the study show that the demonstration method is able to transform abstract concepts into concrete experiences that are easy for students to understand.

Javanese culture is a product of the community’s collective thought, expressed through traditions that have been preserved over generations. However, cultural practices may face decline due to the pressures of modernization and changing times. Therefore, efforts to preserve and sustain cultural heritage are essential. One method of cultural transmission is through traditional practices. The Ngirim Banyu tradition at Sumber Genitri, Claket Village, represents a form of semi-oral folklore that is still regularly performed by the local community in Claket Village, Pacet District, Mojokerto Regency. This tradition is carried out as an expression of gratitude to God Almighty for the blessings received, particularly the natural spring that sustains the village. This study aims to explore the origins, procedures, ritual components (ubarampe), symbolic meanings, functions, transformations, and preservation efforts related to the Ngirim Banyu tradition at Sumber Genitri. The research also seeks to broaden the researcher’s perspective, knowledge, and experience concerning the existence of local traditions. The theoretical framework used in this study includes concepts of folklore, symbolism and meaning, belief systems, cultural functions, cultural change, and cultural preservation strategies.

This study aims to examine teachers' strategies in improving students' understanding of effective sentence concepts through the implementation of the Contextual Teaching and Learning (CTL) model in elementary schools. The issues addressed in this research include how teachers design and implement context-based learning strategies, the challenges encountered during implementation, and the impact on students’ understanding of effective sentence structures. This research employs a literature review method by analyzing various journals, scholarly articles, and relevant documents. The findings indicate that teaching strategies that connect instructional materials with students’ real-life contexts—through CTL components such as constructivism, inquiry, questioning, learning community, modeling, reflection, and authentic assessment—are proven to significantly enhance students’ understanding of effective sentences. Furthermore, the implementation of interactive and meaningful strategies also increases student participation and fosters positive attitudes toward learning the Indonesian language. However, the application of CTL faces several challenges, including limited instructional time, teacher readiness, and diverse student abilities. Therefore, support from the school and professional development for teachers is essential to ensure that CTL-based teaching strategies can be implemented optimally and sustainably.

This study examines how Javanese culture is represented in the tingkeban ceremony of the second child of celebrity couple Lesti Kejora and Rizky Billar, using a critical discourse analysis approach influenced by the post-structuralist theory of Michel Foucault. The tingkeban tradition, originally a private ritual, has been reconstructed into digital entertainment, focusing on aesthetics, religious narratives, and the ideal image of motherhood. By applying Foucault’s concepts of discourse, power, and subject formation, this article reveals how cultural meanings, gender roles, and celebrity identities are formulated through discursive mechanisms on social media platforms. The findings indicate that the event is not merely a means of cultural preservation, but also a symbolic exercise of power that reinforces social norms and preferred identities, particularly those aligned with the middle-class values. In this context, tradition becomes a contested site for the construction and negotiation of meaning in contemporary discourse.

The Pulsed Nuclear Magnetic Resonance (PNMR) technique is a widely used spectroscopic approach for observing the relaxation phenomena of atomic nuclei in a magnetic field. In this technique, the spin-lattice (T1) and spin–spin (T2) relaxation times are key parameters, as they reflect the microscopic dynamics and structure of a material system. This article presents the results of a systematic literature review of fourteen primary references that discuss the fundamental concepts of NMR, PNMR techniques, the measurement of T1 and T2, and PNMR applications. Although NMR research has seen extensive development internationally, scientific literature in the Indonesian language that specifically addresses this topic remains scarce. Therefore, this paper is intended to serve as an initial systematic resource to introduce the basic principles and potential applications of PNMR in physics and materials science.

Mathematics is often perceived as a subject that is difficult for students to master, a notion that has been confirmed by numerous previous studies. One of the contributing factors is the limited variety of instructional media used in classrooms, which affects students' interest and comprehension. Many teachers still lack appropriate learning media to support blended learning approaches. This study aims to develop and implement multimedia-based Educational Instructional Media (EIM) that are valid, practical, and effective. The project utilizes video-based learning to deliver algebra concepts material for Grade VII students at SMPN 252 Jakarta and SMPIT Al-Qudwah. The development process follows the ADDIE model, which includes five stages: analysis, design, development, implementation, and evaluation. During the analysis phase, both learning needs and content requirements were mapped according to SAP (System Analysis and Product). The material was then divided into seven core sections. In the design stage, the curriculum structure, system flow, and user interface were developed. The development stage involved creating instructional content based on the analysis results. The content was then uploaded to the Moodle platform and presented using the Project-Based Learning (PjBL) model.

This Community Service Program (PKM) was implemented in response to the high usage of social media among students, particularly Instagram, which often becomes a platform for cyberbullying. This phenomenon becomes increasingly complex when students come from diverse cultural backgrounds. Comments or posts considered normal in one culture may be perceived as offensive in another. A lack of cultural sensitivity often triggers digital conflict and bullying, which can negatively impact students' mental health. This PKM aims to improve students’ understanding of the dangers of cyberbullying and the importance of cross-cultural communication ethics. The program began with a pre-test to assess participants' initial knowledge, followed by an interactive seminar discussing the concepts of cyberbullying, digital ethics, and real-life case studies. Students then engaged in group discussions and simulations, where they analyzed problematic digital content and formulated empathetic, constructive responses. At the end of the activity, a post-test was conducted to evaluate the program’s effectiveness. The results showed a significant improvement in students’ awareness and attitudes. This program successfully encouraged students to be more thoughtful and responsible in their online interactions and to become change agents in creating a safer, more inclusive digital environment. The outcomes of this program include a scholarly publication, an educational video disseminated on social media, and quantitative data showing an increase in participants’ knowledge. Overall, this initiative contributes to strengthening multicultural digital literacy among today’s youth.
