This KKN program successfully fostered values of social responsibility and ecological awareness among students and strengthened the synergy between students, schools, and the village community.

This community service initiative was designed to increase students' enthusiasm for Arabic language instruction by applying singing techniques in co-curricular activities at Hasanka Islamic Elementary School. The program emerged in response to the low interest of students in learning Arabic, which was considered to be lacking in variety and uninteresting for elementary school children. The approach applied is Participatory Action Research (PAR), which emphasizes active participation between educators, students, and facilitators in all stages of the activity. This method is implemented through a repetitive cycle that includes planning, implementation, observation, and joint evaluation to ensure that each activity is appropriate to the needs of the students and the school environment. Data was obtained through field observations, in-depth dialogues with teachers and students, activity records, and post-instruction group discussions. Descriptive analysis was conducted to identify changes in learning behavior, engagement levels, and students' emotional responses to singing activities. The findings showed a significant increase in student motivation and participation in Arabic language learning. The findings show a significant increase in student motivation and participation in Arabic language learning. Themed songs help them remember vocabulary more effectively, improve simple communication skills, and create a more enjoyable learning atmosphere. Furthermore, students have taken the initiative to compose lyrics and lead study groups. Implicitly, the application of singing techniques has proven to be effective not only in improving linguistic competence, but also in building confidence, creativity, and cooperation in the elementary school environment.

This study aims to explore the values ​​of early Islamic education reflected in the local religious study tradition and its relevance as an alternative educational model in the contemporary era. Early Islamic education has become a primary foundation for the formation of Muslim civilization and character, emphasizing the balance between knowledge, faith, and morals. The local religious study tradition in Indonesia is a legacy of classical Islamic education that maintains spiritual, moral, and social values ​​in community-based learning practices. This study uses a descriptive qualitative approach with a (library research) method that focuses on exploring the concepts, values, and relevance of early Islamic education as reflected in the local religious study tradition. Primary data were obtained from classical Islamic literature such as traditional books, works of previous scholars, and historical sources related to the early Islamic education system. Meanwhile, secondary data include research results, scientific journals, academic books, and contemporary writings relevant to the theme of local religious study and modern Islamic education. The results show that local religious study contains authentic Islamic values ​​such as sincerity, exemplary behavior, togetherness, and respect for knowledge. These values ​​not only reflect the spirit of classical Islamic education but are also relevant for application in contemporary education systems that tend to be rational and individualistic. The local religious study tradition has the potential to become a holistic alternative educational model because it integrates cognitive, affective, and spiritual aspects within a single learning process. Therefore, revitalizing early Islamic educational values ​​through the local religious study tradition can be a solution for shaping students' religious and social character amidst the challenges of modernization and globalization.

This community service research was motivated by the significant challenges faced by Generation Z in maintaining a balance between physical and mental health and productivity in the digital age. The increasing prevalence of mental health disorders and declining discipline among adolescents are important indicators of the need for character building integrated with health education. This study uses a descriptive qualitative approach to describe in depth the process of implementing health and productivity values through observation, interviews, and documentation of activities at school. The results show that interactive education approaches are effective in increasing students' awareness of healthy lifestyles, time management, and personal responsibility. Activities such as thematic education, congregational prayers, and reflective classes serve as a platform for building productive character that emphasizes balance between spiritual, social, and academic aspects. Students showed positive changes in behavior, such as increased regularity in studying, awareness of maintaining cleanliness, and the ability to manage stress and time more effectively. In conclusion, character building based on health and productivity values has a significant impact on shaping a resilient, disciplined, and competitive young generation, and can be used as a model for character education development in Indonesian vocational schools.

Adolescence is a transitional period marked by rapid physical, psychological, and social changes. During this time, hormonal growth occurs as a sign of puberty and the activation of reproductive organs, one of which is breast development. However, these changes can sometimes lead to breast abnormalities such as lumps, pain, or changes in shape that may indicate early signs of health problems. One of the most effective early detection efforts for breast abnormalities is Breast Self-Examination (BSE). This examination is important to be done regularly so that each individual, especially adolescent girls, can recognize the condition of their breasts early on. Unfortunately, many adolescent girls still do not know what BSE is or how to perform it correctly. This study aimed to determine the relationship between the level of knowledge and breast self-examination (BSE) behavior among female students at SMA Negeri 1 Krueng Barona Jaya, Aceh Besar District. This research was a quantitative study using an analytic cross-sectional design. Data collection was carried out on May 27, 2025, with a population of 30 female students from grades X and XI, selected using accidental sampling techniques. Data analysis using the Chi-Square test showed that there was no relationship between knowledge level and BSE behavior, with a p-value of 0.384 (p > 0.05). It is expected that parents and schools can improve adolescent girls’ knowledge about BSE as an effort for prevention and early detection of possible breast abnormalities.  

Early financial management is an important skill for adolescents to form healthy financial behavior. However, observations at MTS Ummul Qura show that most students are still low in financial literacy and are not accustomed to saving. This community service was conducted to improve students' financial literacy through a combination of counseling guidance and saving practices at school. The method used is a case study with a participatory approach, involving students, counseling teachers, homeroom teachers, and school officials. Activities included financial literacy socialization, savings practice training, and regular monitoring and mentoring. The results showed an increase in financial literacy awareness, changes in consumptive behavior to be more rational, and the formation of consistent saving habits with student participation increasing from 25% to more than 70%. The program also received active support from teachers and parents, so it has the potential to become a sustainable school culture. The findings confirm that the integration of counseling and real practice is effective in building adolescent financial literacy and supporting the national financial literacy agenda. 

This  study investigates  the  influence  of  verbal  bullying  on  the  interpersonal  mental  condition  of  students  at  SDI  Harekakae.  Verbal  bullying  refers  to  aggressive  behavior  involving  harsh  words,  insults,  or  threats  that  may  negatively  affect  a  student’s  psychological  well-being.  A  quantitative  method  with  a  correlational  design  was  used.  The  research  involved  320  students  selected  through  proportional  random  sampling.  Instrument  validity  and  reliability  were  confirmed,  with  a  Cronbach’s  Alpha  value  of  0.821,  indicating  strong  consistency.  Normality  testing  using  the  Shapiro-Wilk  method  showed  that  the  data  were  normally  distributed.  Pearson  correlation  analysis  showed  a  weak  and  statistically  insignificant  relationship  (r  =  0.143;  p  =  0.452)  between  verbal  bullying  and  interpersonal  mental  condition.  Although  the  t-test  resulted  in  a  p-value  of  0.032,  further  interpretation  indicated  no  significant  effect  of  the  independent  variable  on  the  dependent  variable.  These  findings  suggest  that  verbal  bullying  does  not  significantly  affect  students'  interpersonal  mental  health  and  highlight  the  importance  of  further  research  to  explore  other  contributing  factors.

CPU scheduling is a core function in modern operating systems that significantly impacts system performance and efficiency. Among various scheduling algorithms, Priority Scheduling is widely used and exists in two main variants: non-preemptive and preemptive. The non-preemptive mode allows a process to run to completion, while the preemptive mode can interrupt a running process for a higher-priority one. Understanding the behavioral differences between these modes is crucial but often challenging through manual calculations. To address this, an interactive web-based application was developed to simulate and visualize both preemptive and non-preemptive Priority Scheduling algorithms. The research method involved designing the system logic based on the core principles of each scheduling variant, followed by implementation using standard web technologies: HTML, Tailwind CSS, and JavaScript. The application allows users to input custom process data or load predefined case studies, select the scheduling mode, and instantly receive a comprehensive analysis. The results include a dynamically generated Gantt chart, a detailed performance metrics table (including turnaround time and waiting time), and a step-by-step execution log. Through a comparative analysis of a specific case study, the application is proven to be an effective educational tool. It accurately simulates both modes and visually demonstrates the impact of preemption on execution order, resource utilization, and key performance metrics, thereby simplifying the learning process for students and educators.

The concept of hubuddunya (love of the world) within the Akidah Akhlak subject holds a strategic role in shaping the moral and spiritual character of students, particularly in the midst of globalization, materialism, and consumerist culture that increasingly influence young generations. This study seeks to critically analyze the teaching materials of Akidah Akhlak for Grade X at MA YASPI Cicantayan, focusing on the hubuddunya topic. The main objective is to evaluate the relevance, depth, and effectiveness of these materials in fostering students’ awareness of moral values, as well as their ability to apply Islamic principles in daily life. This research employs a qualitative approach with a descriptive method, collecting data through documentation of learning resources, observation of lesson plans (RPP), and in-depth interviews with teachers. The data analysis process was conducted through reduction, classification, and interpretation of findings to obtain a comprehensive picture of the existing instructional practices. The results reveal that the current teaching materials tend to remain highly theoretical and emphasize the transfer of knowledge rather than transformative learning. Consequently, they do not adequately address contextual issues faced by students in their real-life environment. The affective and psychomotor aspects of students’ moral development are not optimally stimulated, leaving a gap between conceptual understanding and practical application. Furthermore, essential Islamic values such as zuhud (detachment from excessive worldliness), qanaah (contentment), and tawakal (trust in God) have not been integrated effectively as counterbalances to materialistic tendencies. The implications of this study underline the urgency of developing Akidah Akhlak teaching materials that are more contextual, student-centered, and relevant to contemporary challenges. Such materials should not only transmit religious knowledge but also foster reflective thinking, emotional maturity, and behavioral consistency, thereby preparing students to face globalization with strong faith, resilience, and anti-materialistic attitudes.

The moral crisis and low religious understanding among the younger generation pose serious challenges in shaping students' character in accordance with Islamic teachings. This phenomenon is increasingly exacerbated by the rapid flow of globalization and technological developments that are not always in line with the principles of Islamic law. In this context, the existence of Madrasah Diniyah (Islamic Madrasah) is a strategic solution to equip students with a deep understanding of religion while simultaneously forming a strong Islamic personality (syakhsiyah Islamiyyah). This study aims to determine the role of Madrasah Diniyah in improving mastery of Islamic religious knowledge and shaping Islamic character in students. The study used a descriptive qualitative approach with the aim of systematically describing the learning process and its impact on student development. Data were collected through observation, in-depth interviews with teachers and students, and analysis of learning documents. The results show that Madrasah Diniyah plays a significant role in improving mastery of Islamic religious knowledge through structured learning that includes the Qur'an, aqidah, fiqh, and morals. This material not only broadens students' religious knowledge but also instills the values of faith, worship, and noble morals that serve as the foundation for daily behavior. This success is supported by teachers who possess strong scientific and pedagogical competence, varied learning methods, and harmonious relationships between teachers, students, and parents. Furthermore, a conducive madrasah environment helps strengthen the internalization of Islamic values. Thus, Madrasah Diniyah serves as a vital partner in the Islamic education system, particularly in instilling an Islamic personality from an early age, thus fortifying the younger generation against the negative influences of globalization and shaping a generation of faith, knowledge, and noble morals.

This study investigates the effect of added sugar on the stability of soap bubbles through a hands-on science activity titled “Magic Bubbles” conducted with third-grade students at SDN 1 Karangrejo. The activity was implemented collaboratively, where students observed, experimented, and drew conclusions together under teacher guidance, without the use of individual worksheets. Using a participatory observation method, the research described students’ engagement, reactions, and learning behavior during the process. Findings revealed that soap bubbles containing added sugar demonstrated greater stability and a longer lifespan compared to those without sugar. Students showed high levels of enthusiasm, curiosity, and active participation throughout the experiment. The activity not only fostered engagement but also enhanced students’ gross motor coordination, observation skills, and early scientific reasoning. Furthermore, it encouraged cooperative learning and communication among peers. The results highlight the effectiveness of simple laboratory-based learning as a medium to introduce scientific inquiry at the elementary level. The “Magic Bubbles” activity aligns with the inquiry-based learning approach in science education, emphasizing direct experience, experimentation, and concept discovery through observation and guided reflection. This study demonstrates that contextual, play-based science activities can meaningfully improve motivation and conceptual understanding among young learners.

Civic Education (PKn) has a strategic role as the main means in internalizing the values of Pancasila to students. Through PKn, the process of forming the character and personality of citizens can be carried out systematically, sustainably, and contextually, based on the values of divinity, humanity, unity, democracy, and justice. The internalization of these values is not only through mastery of concepts, but also through habituation of attitudes and behaviors in daily life. An interactive, reflective, and social project-based approach to learning allows learners to actively develop moral awareness, social responsibility, and a sense of nationalism. PKn functions as a character education instrument that not only forms civic knowledge, but also builds a strong national identity and a tolerant spirit. In the context of globalization and the challenges of the digital era, civil society is an important foundation in equipping the young generation to be able to be critical, adaptive, and still uphold national values. Therefore, PKn is not just a formal subject, but a strategic vehicle in forming a generation with Pancasila character who is ready to contribute positively to the life of society, nation, and state. This research emphasizes the urgency of PKn revitalization as a transformative and contextual value education.

This study focuses on analyzing how financial literacy, risk perception, and income level influence investment decision-making among students. The background of this analysis arises from the low understanding of financial management and the importance of risk considerations in investment among students. A quantitative survey method was employed, involving 93 students selected through purposive sampling. Data were processed using multiple linear regression analysis along with validity, reliability, and classical assumption tests. The findings indicate that financial literacy and risk perception have a significant positive effect on investment decisions, while income does not have a partial effect. Simultaneously, all three variables positively influence investment decisions. These results emphasize the need for students to understand financial literacy and risk awareness to make informed investment decisions. The practical implications of this study support the development of effective financial education for students and serve as a reference for future research on investment behavior and personal financial management.

This research aims to evaluate how the optimization of the private learning system contributes to improving the understanding of Islamic values among students and the community in Peria-ria Village, Biru-Biru District, Deli Serdang Regency. Using a qualitative descriptive approach, this study explores how private learning methods are implemented in Islamic Religious Education (PAI) and how they impact learners’ comprehension, character development, and social awareness. Data were collected through direct observation, in-depth interviews with teachers, community leaders, and students, as well as documentation during the 2025 Independent Community Service (KKN Mandiri) program conducted by Universitas Muhammadiyah Sumatera Utara. The findings show that private learning based on Islamic values effectively enhances students’ understanding of akidah, ibadah, and akhlaq in a more interactive and contextual way. The learning process encourages not only religious knowledge but also positive behavioral change, responsibility, and social solidarity within the community. Although this model requires consistent mentoring, it provides valuable insights for developing more adaptive and sustainable Islamic education strategies at the community level.

The emergence of smartphone technology has brought significant changes to the world of education while simultaneously creating new challenges for teachers. This study aims to identify and analyze the challenges teachers face in the learning process following the widespread use of smartphones by students. The method used was a literature review, examining various sources on digital learning, student behavior, and the impact of technology on the educational process. The results indicate that teachers face various challenges, including student concentration disruptions due to entertainment content, over-reliance on technology, student access to age-inappropriate content, lack of parental supervision, unequal access to devices, and the emergence of digital ethics issues such as social media misuse and cyberbullying. These conditions require teachers to have stronger digital competencies, adaptive classroom management skills, and pedagogical strategies that balance technology use with character building and healthy digital discipline. To address these challenges, four main strategies can be implemented: enhancing digital competence, integrating character values in technology use, innovating learning methods, and building collaboration among teachers in designing digital learning.

Multicultural counseling in schools serves as an essential strategy to reduce conflicts and foster cultural awareness among students. Counselors play a central role by developing their own cultural competence, facilitating students’ reflection on their cultural identities, providing education on stereotypes and biases, creating safe spaces for cross-cultural dialogue, and strengthening institutional capacity through collaboration with teachers and parents. This counseling strategy emphasizes understanding the values, norms, and power dynamics of each cultural group to ensure interventions are both effective and culturally sensitive. An inclusive learning environment supports this process by offering written policies, curricula that reflect diversity, dialogue forums, and cross-cultural activities. The evaluation process involves establishing clear objectives, quantitative and qualitative indicators, and mixed methods, including surveys, discussions, and direct observations, with participation from counselors, teachers, principals, parents, and student representatives. Local adaptation of instruments, continuous monitoring, and systematic documentation ensure data validity and the sustainability of behavioral changes. Evaluation results form the basis for concrete recommendations, such as counselor training, inclusive curriculum development, and programs to strengthen cross-cultural relationships. This approach enables schools to cultivate a culture of empathy, understanding, and harmony, thereby enhancing relationships among students from diverse backgrounds.

This study aims to analyze the effectiveness of the sorogan and bandongan methods in Islamic boarding school (pesantren) learning through the perspective of educational psychology. Using a qualitative-descriptive approach based on library research, this study explores the relevance of these traditional teaching methods to behaviorist, cognitivist, and constructivist learning theories. The findings reveal that the sorogan method, which emphasizes personal interaction between students (santri) and teachers (kiai), plays a crucial role in improving reading accuracy, learning discipline, independence, and metacognitive abilities. Meanwhile, the bandongan method, which is conducted collectively, proves effective in strengthening conceptual understanding, fostering social learning, and internalizing moral and spiritual values within a communal context. The integration of these two methods represents a synergy between the intellectual tradition of pesantren and the principles of modern educational psychology that emphasize affective, cognitive, and psychomotor aspects. The results indicate that the combined application of sorogan and bandongan can support the development of an adaptive pesantren curriculum aligned with the demands of 21st-century education while maintaining the Islamic scholarly tradition that serves as the foundation for character formation and personal development.

This article offers a philosophical exploration of two classical concepts of self-control: zuhud in Islamic intellectual tradition and apatheia in Stoic philosophy, within the framework of modern character education. Using a qualitative library research approach, this study employs content analysis and philosophical hermeneutics to examine the works of key thinkers such as Al-Ghazali, Ibn Qayyim al-Jawziyyah, Marcus Aurelius, and Epictetus. The findings indicate that zuhud emphasizes detachment from material desires through spiritual awareness and prioritization of divine values, while apatheia focuses on achieving inner peace and moral clarity by rationally managing emotions and eliminating unnecessary passions. Although rooted in different theological worldviews, both concepts converge in promoting a form of self-control that enhances inner freedom, ethical behavior, and self-discipline. This study argues that the integration of zuhud and apatheia can enrich contemporary character education by balancing rational moral reasoning with spiritual consciousness. The educational model proposed in this research emphasizes the importance of teaching students to reflect critically, regulate their emotions, and cultivate inner balance rooted in universal ethical values. Thus, the synthesis of both traditions contributes to the advancement of character education that is holistic, contemplative, and morally grounded.
