This article explores mathematical logic as a fundamental discipline within mathematics that systematically investigates the principles of valid, coherent, and consistent reasoning. Mathematical logic serves as an essential foundation for developing structured thinking and constructing well-grounded, persuasive arguments supported by clear justification. It primarily focuses on the processes of reasoning, argumentation, and formal proof, enabling individuals to distinguish between valid and invalid conclusions. By establishing precise rules and logical structures, mathematical logic provides a rigorous framework for assessing the strength and consistency of arguments. The discipline emphasizes clarity, objectivity, and analytical accuracy in examining propositions and their relationships. In practice, mathematical logic is presented through the use of symbolic representations, formal logical statements, connectives, quantifiers, and truth tables to analyze patterns of reasoning and verify the truth values of statements. These systematic tools allow complex ideas to be evaluated methodically, prevent logical fallacies, and ensure that conclusions are derived from sound and demonstrable reasoning principles.

Waste-related issues have become increasingly complex environmental challenges as a result of population growth and shifting consumption patterns within society. Although Indonesia has established a legal framework through Law Number 18 of 2008 on Waste Management, its implementation at the community level continues to encounter various obstacles, particularly low legal awareness and an underdeveloped legal culture. This community service program aims to foster and strengthen a legal culture in waste management as an effort to promote environmental sustainability in Mrutuk Village, Widang District, Tuban Regency. The activities were conducted using participatory and descriptive approaches, including legal education, dissemination of waste management regulations, reinforcement of legal substance and enforcement structures, and community-based assistance. The results demonstrate an improvement in public understanding and awareness of the importance of managing waste in accordance with legal provisions, a shift in attitudes from compliance motivated by supervision toward voluntary compliance, and the emergence of community initiatives to actively engage in environmentally oriented waste management. Therefore, strengthening legal culture has proven to be a crucial instrument in encouraging environmentally responsible behavior and supporting the achievement of sustainable development.

The phenomenon of moral degradation and the increase in negative activities among children during the crucial hours between dusk and evening have become serious challenges for the community in Ujung Negeri Kahan Village. This community service research aims to evaluate and optimize the role of the "Maghrib Mengaji" program as a preventive instrument to shield children from unhealthy environmental influences and gadget dependency. The method employed in this service is participatory mentoring using the Asset-Based Community Development (ABCD) approach, involving religious leaders, parents, and village officials. Through the restructuring of activities in mosques and prayer rooms, this program focuses not only on Qur'anic literacy but also on the cultivation of noble character (akhlakul karimah). The results indicate a significant transformation in behavior; children who previously engaged in counterproductive outdoor activities are now more focused on positive spiritual and social endeavors. The success of the program is indicated by a decrease in the intensity of nighttime wandering and an increase in learning discipline. The conclusion of this activity confirms that community synergy through structured religious programs is effective in reducing the potential for juvenile delinquency and strengthening the moral resilience of the younger generation at the rural level.

This training, which is carried out in a structured and systematic manner for micro and small industry players, is expected to be able to improve flexible and effective joint marketing and ensure the sustainability of MSI businesses in the future .

This study explores the intersection of feminism and gender equality in Bali, analyzing how patriarchal norms, media portrayals, and religious customs marginalize Balinese women. Using Simone de Beauvoir’s concept of the “Other,” it examines why feminism faces resistance despite growing gender equality awareness. Through surveys and interviews with Balinese women aged 11–20, the findings reveal that many support gender equality but hesitate to identify as feminists due to cultural misconceptions and Western associations. The research highlights the need for educational initiatives and community discussions to integrate feminism into Balinese traditions, showing that culturally adapted advocacy is more effective than universalist approaches. It underscores the importance of feminist education, local leadership engagement, and promoting women’s roles within traditional structures, demonstrating that feminism and Balinese traditions can coexist without disrupting social harmony. Future research should explore generational shifts, digital media’s role in shaping perceptions, and comparative studies in other traditional societies to further bridge feminism and cultural values.

This study examines inclusive education for children with emotional and behavioral disorders (EBD), who often experience significant challenges in social interaction and academic adaptation. The primary objective is to evaluate existing educational approaches and strategies implemented in Indonesia, while also identifying gaps in current research and practice. This study employs a literature review method, analyzing 20 relevant scientific articles to synthesize key findings and trends. The results indicate that structured approaches such as Positive Behavioral Interventions and Supports (PBIS) and Social-Emotional Learning (SEL) have proven effective in improving students’ behavioral outcomes, emotional regulation, and academic performance. These approaches emphasize proactive strategies, skill development, and supportive learning environments. However, several persistent challenges hinder optimal implementation, including limited teacher knowledge and training in inclusive practices, insufficient institutional support, and a lack of access to professional psychological services. Additionally, inconsistencies in policy implementation across regions contribute to unequal educational experiences for children with EBD. Based on these findings, the study highlights the importance of strengthening teacher capacity through continuous professional development and increasing access to multidisciplinary support systems. Furthermore, effective collaboration among teachers, parents, schools, and the wider community is essential to foster inclusive, adaptive, and responsive educational environments that can meet the diverse needs of all learners.

This study aims to examine the effect of reproductive health education on adolescent knowledge as an indicator of sexual behavior prevention among students of SMA Negeri 11 Tidore Kepulauan.

This article explores the meaning of human life through the lens of value, choice, and ultimate purpose. Drawing from the analogy of nature, the study argues that human existence is likewise structured around meaning rather than randomness. Human beings inevitably encounter diverse and sometimes conflicting values, requiring discernment and responsible decision-making. Not all values carry equal weight; their significance depends on their proximity to the ultimate goal of human life understood in its totality. The paper identifies three fundamental attitudes toward life: a pessimistic stance that perceives life as failure, a hedonistic stance that seeks satisfaction and pleasure, and a constructive stance that embraces life as a meaningful vocation. Through a reflective-ethical approach, the discussion highlights the importance of mission, prioritization, empathetic communication, synergy, and continual self-renewal. Ultimately, the quality of human existence is determined by the values one chooses to uphold and the orientation of life toward a higher, integrative purpose.

This research explores the narrative of Cain and Abel in Genesis 4:1-16 to dissect the concepts of sin and moral responsibility within a modern Christian context. Amidst the rising tide of individualism and "bystander culture," ethical responsibility toward others is often neglected behind religious formalities. Utilizing a qualitative method with a biblical exegesis approach, this study analyzes narrative structures, the personification of sin, and the dynamics of the dialogue between God and Cain. The findings indicate that sin in this text is understood as a relational failure and a failure of self-mastery, where humans possess the moral authority to conquer destructive impulses. Cain's rhetorical question, “Am I my brother’s keeper?”, is identified as a form of moral erosion leading to social and ecological alienation. However, God’s provision of a “mark” for Cain affirms that divine justice is always accompanied by the grace of providence. This research concludes that moral responsibility is a fundamental essence of humanity that demands the integration of ritual piety and social integrity. These findings are expected to serve as an ethical framework for academic and ecclesiastical communities, particularly in restoring the commitment to be “keepers” of one another amidst contemporary moral crises.

This study evaluates the effectiveness of group counseling integrated with self-management techniques in minimizing students' academic procrastination. Procrastination is a prevalent academic challenge driven by deficiencies in self-regulation, poor time management, and a lack of learning motivation. A quasi-experimental approach was employed, utilizing a pretest-posttest design. The participants consisted of students identified with high levels of task avoidance. The intervention was delivered through structured group counseling sessions focusing on self-monitoring, self-evaluation, and self-reinforcement strategies. The findings reveal a significant reduction in procrastination levels following the treatment. These results reinforce existing theories regarding the critical role of self-regulation in academic behavior. This study implies that organized self-management frameworks within group counseling can effectively foster student discipline and accountability toward their academic obligations.

Mental resilience is a crucial psychological asset that determines the performance consistency of athletes under competitive and training pressures. This study aims to analyze the mental resilience of karate athletes at SMAN 3 Tana Toraja from the perspective of guidance and counseling. Employing a descriptive qualitative method, data were gathered through in-depth interviews, participatory observation, and documentation involving eight karate athletes and two coaches selected through purposive sampling. Data analysis followed the interactive model of Miles, Huberman, and Saldaña encompassing data condensation, data display, and conclusion drawing. The findings reveal that athletes generally demonstrate moderate to high levels of mental resilience, characterized by adaptive emotional regulation, positive self-talk, and effective coping strategies. Supporting factors include intrinsic motivation, coach social support, peer cohesion, and cumulative competitive experience. Inhibiting factors comprise unmanaged pre-competition anxiety, absence of structured post-defeat psychological recovery, and limited institutional counseling support. From the guidance and counseling perspective, these findings underscore the critical need for integrating psychological skills training into the karate coaching program, including counselor-facilitated group counseling sessions and individual psychological development plans tailored to each athlete.

This study investigates the effectiveness of implementing group counseling services using self-regulation learning strategies to improve students' learning discipline. Learning discipline plays a crucial role as a determining factor of academic success; nevertheless, many senior high school students still demonstrate weaknesses in managing their time and fulfilling their academic responsibilities. This study adopted a quantitative approach through a quasi-experimental method utilizing a pre-test and post-test control group design. Subjects were selected using purposive sampling technique with low learning discipline scores as the primary selection criterion. Data were collected using a learning discipline scale that had been tested for its validity and reliability. Hypothesis testing was conducted through a paired sample t-test to detect changes occurring before and after the intervention was administered. The results demonstrated a meaningful improvement in students' learning discipline following participation in group counseling sessions incorporating self-regulation strategies. This technique proved beneficial in helping students plan, monitor, and evaluate their learning activities in a more structured manner. These findings suggest that incorporating self-regulation learning into group counseling has strong potential to become a leading strategy for school counselors in enhancing student discipline and academic achievement.

This study aims to examine the application of group guidance in improving students' learning processes at the secondary school level. Group guidance is one of the services in guidance and counseling that allows students to discuss, share experiences, and develop problem-solving skills in a group setting. The background of this research stems from the observation that many students experience difficulties in their learning process, including low motivation, ineffective learning strategies, and an inability to manage academic pressure. The method used in this study is a literature review approach that examines various relevant research and theories. The results show that group guidance has a significant positive impact on improving students' learning processes, including increasing learning motivation, developing effective study habits, enhancing social interaction among students, and reducing academic anxiety. Group guidance also provides a safe space for students to express their academic difficulties and receive constructive support from peers and counselors. The implications of this research suggest that group guidance services need to be consistently and systematically implemented in schools as part of a comprehensive guidance and counseling program. Schools are recommended to design structured group guidance programs with clear objectives and methods tailored to students' developmental needs. This approach is proven to be effective in supporting students' academic achievement and personal development.

Instilling saving habits from an early age is an essential component of character education, particularly in fostering discipline, responsibility, and independence. Initial observations at PAUD Nurul Islam, Jelutih Village indicate that early childhood saving interest remains relatively low due to limited engaging learning media and the absence of structured habituation. This Community Service Program (KKN) aims to foster early childhood saving interest through creative piggy bank media aligned with children’s developmental characteristics. The implementation method comprised planning, execution, and evaluation stages. During execution, children were introduced to saving concepts through simple storytelling and interactive dialogue, followed by hands-on creation of creative piggy banks using simple, child-friendly materials. These piggy banks were then used to habituate saving behavior. The results demonstrate increased enthusiasm and saving interest among children, reflected in their willingness to set aside money and heightened responsibility toward their piggy banks. Therefore, creative piggy bank media serve as an effective alternative learning tool for fostering saving interest and positive character development among early childhood learners at PAUD Nurul Islam, Jelutih Village.

The phenomenon of mafqud (missing heirs) creates complex legal issues within Islamic inheritance law, particularly regarding the realization of justice and legal certainty in the distribution of estate assets. This study examines the legal position of mafqud as a temporary impediment in inheritance allocation and analyzes the procedural mechanisms applied by religious courts in determining mafqud status. Employing a normative juridical method, this research relies on primary legal materials, including the Qur’an, Hadith, classical fiqh references, and relevant judicial decisions, supported by secondary materials such as academic books and scholarly journals. The findings indicate that mafqud serves as a temporary barrier to inheritance distribution, requiring careful judicial assessment to ensure the protection of all heirs’ rights while remaining consistent with Islamic legal principles and the applicable national legal system. Therefore, structured and systematic procedures implemented by religious courts play an essential role in guaranteeing both justice and legal certainty in inheritance disputes involving mafqud.

The development of Digital Marketing and Electronic Word of Mouth (eWOM) has encouraged hospitals to adopt digital communication strategies to attract patients’ visit intentions. However, in public hospitals, the effectiveness of these strategies in influencing patient behavior still requires empirical validation. This study aims to analyze the influence of Digital Marketing and eWOM on patient visit intention, with Brand Awareness as an intervening variable at RSUD Cengkareng.This research employed a quantitative approach with an explanatory design. Data were collected from November to December 2025 from 100 general outpatient respondents selected using the Slovin formula and a simple random sampling technique. The data were gathered through structured questionnaires and analyzed using Structural Equation Modeling (SEM) with AMOS software.The results show that Digital Marketing and eWOM have a positive and significant effect on Brand Awareness. Both variables also significantly influence patient visit intention, with eWOM demonstrating the strongest effect. These findings indicate that information shared through digital platforms and patient recommendations plays an important role in shaping potential patients’ decisions to visit the hospital. However, Brand Awareness does not have a significant effect on patient visit intention and does not mediate the relationship between Digital Marketing, eWOM, and visit intention. This suggests that, in the context of RSUD Cengkareng as a public hospital, patients’ visit decisions are more directly influenced by digital information exposure and the credibility of online recommendations rather than by brand recognition alone.

Compliance with clinical pathways is a critical component in ensuring quality of care, patient safety, and cost efficiency in hospitals. However, its implementation continues to face challenges related to management systems and the work behavior of Healthcare Providers (HCPs). This study aimed to analyze the effect of performance-based remuneration systems and organizational support on clinical pathway compliance, with work discipline serving as an intervening variable among HCPs at Cabangbungin Regional General Hospital.This research employed a quantitative approach with an explanatory research design. Data were collected using structured questionnaires and analyzed through Structural Equation Modeling (SEM) with a Partial Least Squares (PLS) approach, supported by the three-box method analysis. The findings indicate that performance-based remuneration systems and work discipline have a significant positive effect on clinical pathway compliance. Furthermore, work discipline was found to strengthen the relationship between performance-based remuneration and compliance, confirming its mediating role. In contrast, organizational support did not show a significant direct or indirect effect on clinical pathway compliance.The study concludes that compliance with clinical pathways is more strongly influenced by performance control mechanisms and clinical work discipline than by general organizational support. These findings provide evidence-based insights for hospital management in designing sustainable strategies and policies to enhance clinical pathway adherence and improve service quality.
