Work activities in workshops often require static and repetitive body positions, such as bending over, lifting heavy loads, or reaching into narrow areas of vehicles. These habits can gradually cause muscle tension and lead to neck and lower back pain. Given the high risk, physiotherapy counseling on occupational safety and health (OSH) and ergonomics was conducted to provide practical understanding to B-Garage, Batu City workshop workers. The counseling was delivered interactively through material presentations, direct discussions, and demonstrations of stretching exercises that can be easily applied in daily activities. The results of the activity showed a very significant increase in knowledge; participants who initially did not understand the principles of ergonomics and musculoskeletal pain prevention were able to identify work risks and practice stretching exercises correctly after the education session. This change was clearly evident from the post-test results, which showed a significant overall improvement compared to the pre-test. These findings indicate that physical therapy education not only enhances knowledge but also promotes behavioral changes toward safer, more comfortable, and more productive work patterns.

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.

The contemporary digital era has triggered the normalization of pornography and promiscuous sexual behavior, which significantly threatens the theological understanding and sacramental practice of Catholic marriage among young adults. This article aims to examine, from a theological-juridical perspective, how canons 1055–1101 of the Code of Canon Law (CIC) serve as the authoritative foundation for the Church in safeguarding the dignity and validity of the sacrament of marriage. The method employed is a comprehensive literature study of the CIC, relevant magisterial documents of the Church, and contemporary scholarly works on the dynamics of young adult relationships. The concise findings indicate that exposure to and normalization of pornography directly weaken three fundamental aspects of Catholic marriage, namely the capacity to give free consent, the intention to practice permanent fidelity, and the correct understanding of the body’s meaning as a total self-gift. Nevertheless, the Church possesses solid canonical and pastoral instruments to address these challenges and facilitate restoration. In conclusion, a synergistic integration of canonical approaches, moral teachings, and pastoral guidance is required to assist young adult couples so that they may realize marriages that are not only canonically valid but also psychologically mature and sacramentally holy.

This study aims to describe the characteristics of SMK Al-Azami students in emulating the morals of the Prophet Muhammad (peace be upon him) as part of character development based on Islamic values within vocational education. The background of this research lies in the urgency of character education that not only emphasizes academic competence and technical skills but also focuses on moral formation and professional ethics. This research employed a qualitative approach using a library research method by analyzing relevant classical and modern Islamic literature, supported by documentation of school activities. The results reveal that the moral values of the Prophet Muhammad have been well internalized in students’ daily behavior, which includes four core dimensions: Shidq (honesty), Amanah (trustworthiness), Istiqamah (discipline), and Rahmah (compassion). The value of Shidq is reflected in students’ honesty during vocational practice and in reporting work results; Amanah is demonstrated through responsibility for tools and group tasks; Istiqamah appears in punctuality, consistency, and work discipline; and Rahmah is shown through respectful, empathetic, and cooperative social interactions. The findings indicate that Islamic character education effectively shapes students with integrity, discipline, and social awareness, serving as a model for moral development in vocational schools. Furthermore, this research highlights the importance of strengthening teacher exemplarity, religious habituation, and curriculum integration of Islamic moral values in vocational learning to ensure sustainable character development.

This study examines the concept of the Great Filter as a metaphor to explain why only a few Islamic missionary organizations and startups are able to survive amidst digital disruption, while many others fail. Disruption, characterized by rapid changes in technology, regulations, and societal behavior, creates significant pressure that demands high levels of adaptability and innovation. This study uses a qualitative method based on a literature review by analyzing various literature related to entrepreneurship, digital missionary work, and dynamic capabilities. The results show that the success of Islamic missionary organizations in facing disruption is determined by a combination of visionary leadership, continuous innovation, mastery of digital technology, and the organization's ability to learn and adapt. Conversely, failure is often caused by limited funding, minimal innovation, and weak digital strategies. Thus, the Great Filter can be understood as a natural selection process that only resilient, adaptive organizations can overcome, and is able to combine spiritual values with entrepreneurial innovation.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in the economy by creating jobs, reducing poverty, and contributing to the Gross Domestic Product (GDP). However, many MSMEs still struggle to market their products effectively. Limited capital, workforce, and access to promotional media lead them to rely on conventional methods such as print advertising, with minimal use of digital platforms. These limitations hinder their ability to reach wider markets and compete effectively at both local and national levels. Furthermore, differences in approach between MSMEs and large companies influence their marketing strategies. MSMEs often prioritize social networks and personal relationships over structured and systematic marketing plans. As a result, traditional methods are insufficient to face increasing competition and shifts in consumer behavior. Therefore, research was conducted on more innovative, creative, and adaptive marketing strategies for Ubay Singkong Keju MSMEs so that they could survive and thrive amid the ever-changing market dynamics.

This research is motivated by the importance of improving employee performance in the public sector, particularly at the Department of Education of Kediri City, which faces challenges related to work discipline, workload, and the phenomenon of cyberloafing.

The rapid development of digital technology has significantly transformed commercial activities, particularly through the emergence of marketplaces as platforms for online transactions. The vast number of products available in a marketplace often creates difficulties for users in finding items that suit their needs and preferences. To address this challenge, a recommendation system is required to provide personalized and relevant product suggestions. This study discusses the implementation of a product recommendation system in a marketplace using the Collaborative Filtering method. This method works by leveraging information from users’ previous behavior, such as purchase history, ratings, and similarity of preferences with other users, to generate more accurate product recommendations. The Collaborative Filtering approach has proven effective in identifying user preference patterns based on relationships between users as well as between items. This study employs user interaction data such as ratings and shopping activities as the processing foundation. The process involves data collection, preprocessing, calculation of similarity between users or products, and generating recommendation lists. The results indicate that this method enhances the shopping experience by providing relevant product suggestions tailored to user interests, thereby increasing customer satisfaction and potentially improving sales performance in the marketplace. Thus, the application of a Collaborative Filtering-based recommendation system not only simplifies product discovery for users but also offers strategic advantages for marketplace operators in digital business competition

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It is transmitted through the air, specifically through droplets expelled by sufferers when coughing or sneezing. TB is divided into two main types: pulmonary TB, which attacks the lungs, and extrapulmonary TB, which can affect other organs such as the pleura, lymph nodes, skin, bones, and meninges. In the Community Health Center (Puskesmas) work area, 77 new cases of pulmonary TB were recorded from January to April 2025. Meanwhile, coverage of Tuberculosis Prevention Therapy (TPT) only reached 44.7%, still below the national target of at least 50%. This condition indicates the need for increased health promotion activities and community diagnostic approaches as promotive and preventive measures, in order to increase TPT coverage and reduce the incidence of TB. The results of the respondent questionnaire showed that the level of public knowledge about TB reached 64.6%, positive attitudes at 94%, and preventive behavior at 72%. Based on these findings, it is recommended that outreach activities be conducted regularly to improve public understanding, which can ultimately encourage behavioral changes and reduce TB cases.

This study assesses the influence of organizational culture, physical work environment, and non-physical work environment on employee performance at UD. Sumber Rejeki. Organizational culture is understood as the values, norms, and patterns of behavior agreed upon by members. The physical work environment refers to tangible conditions such as layout, lighting, and cleanliness. The non-physical work environment relates to the psychological climate and social relationships in the workplace. The research design is quantitative with a census or saturated sample technique. All 32 employees were respondents. The instrument was compiled using a Likert scale. The data were processed using SPSS 25. The analysis stages included validity, reliability, normality, multicollinearity, heteroscedasticity, multiple linear regression, t-test for partial effects, f-test for simultaneous effects, and the coefficient of determination R². The partial test results showed that organizational culture did not have a significant effect on employee performance. Conversely, the physical work environment and non-physical work environment had a positive and significant effect. The simultaneous test confirmed that the three variables together had a positive and significant effect on performance. These findings indicate that improvements in physical aspects such as room comfort, equipment, and safety standards, as well as strengthening non-physical aspects such as supervisor support, role clarity, and communication, are more directly related to performance improvement than existing cultural characteristics. In practical terms, management needs to prioritize programs to improve the physical work environment and psychological climate, accompanied by periodic evaluations so that the impact can be measured against performance indicators.
