Leaf springs serve as vehicle weight supports and vibration dampers from uneven roads. Reducing vehicle weight can support fuel consumption reduction. The use of composite materials allows for a reduction in leaf spring weight without reducing load capacity and stiffness. The purpose of this study was to find the composition of composite leaf springs with a polyurethane matrix that were resistant to tensile and flexural tests using e-glass, epoxy, and polyurethane materials. This study used an experimental method, in which specimens were tested using a tensile and flexural testing machine. The variations included polyurethane matrices of 10%, 20%, and 30%. The data was statistically analyzed using Excel to determine the significant effect of the variables. The results showed the effect of polyurethane variation on the composite. The tensile test showed that the greatest tensile stress was on the 30% polyurethane specimen at 1.574 N/mm² and the smallest was on the 10% specimen at 7.007 N/mm². In the flexural test, the greatest effect on flexural strength was observed in the 30% specimen at 14.36 MPa and the smallest in the 10% specimen at 25.82 MPa. Without the addition of polyurethane, the tensile stress was 39.678 N/mm² and the flexural strength was 157.09 MPa. Conclusion: The addition of polyurethane reduces the mechanical strength of composite leaf spring material without polyurethane addition.

Composite materials have the potential to be used as an alternative material for e-scooter frames due to their low weight and good mechanical strength. The mechanical properties of composite materials are strongly influenced by their constituent materials, particularly the fiber fraction. This study aims to analyze the effect of fiberglass composition variations on the tensile strength of composite materials as an alternative for e-scooter frames. The results show that increasing the fiberglass content leads to an improvement in the tensile strength of the composite material. The tensile strength increased by 51.52% when the fiberglass content was increased from 40% to 50%, while an increase of 19.5% was observed from 50% to 60%, indicating a decreasing rate of improvement. At higher fiberglass compositions, voids were observed due to imperfections in the manufacturing process, which affected the bonding between the fiber and the resin. In addition, increasing the fiberglass content resulted in a reduction in tensile strain from 1.1% at 40% fiberglass to 0.55% at 60% fiberglass, indicating that the material became stiffer and more brittle. These results indicate a trade-off between increased tensile strength and reduced ductility of the composite material.

The advancement of automotive technology has accelerated the adoption of renewable‑energy‑based electric vehicles, including the integration of solar panels on electric scooters. Indonesia’s tropical climate provides abundant solar energy potential; however, the limited surface area of scooters often restricts panel placement to the footrest section. This study aims to evaluate the impact of using a 10 mm clear acrylic cover on the performance of a 50 Wp monocrystalline solar panel in an electric scooter battery‑charging system. An experimental method was employed by comparing the panel’s performance under two conditions: without a cover and with the acrylic cover installed. Key parameters observed included voltage, current, and charging power, recorded using a data logger. Tests were conducted for 30 minutes under varying solar radiation intensities. The results indicate that the acrylic cover reduces the panel’s output power, from 55 W to 45 W at a solar radiation intensity of approximately 1100 W/m². These findings suggest that the use of an acrylic cover must be carefully considered to maintain optimal charging system performance.

Learning the Qur'an in Islamic Elementary Schools requires an approach that emphasizes not only reading skills but also understanding the meaning and internalizing the Qur'anic values ​​contextually. However, learning practices that are still dominated by conventional methods have the potential to reduce student engagement and interest in learning, especially in narrative materials such as animal stories in the Qur'an. This study aims to examine the effectiveness of the Qur'anic Magic Cards media as a learning medium for animals in the Qur'an in increasing the understanding and interest in learning of students in Islamic Elementary Schools. This study uses a qualitative approach with data collection techniques through observation, interviews, and documentation. The results show that the use of the Qur'anic Magic Cards media can help students understand the meaning of verses more concretely, increase active involvement during learning, and foster interest in learning the Qur'anic material. This media also contributes to creating a fun, contextual, and meaningful learning atmosphere, so that the messages of the Qur'an are not only understood textually but also internalized in the learning process. Thus, the Magic Quran Cards can be used as an innovative and relevant alternative Quranic learning medium for implementation in Islamic Elementary Schools (Madrasah Ibtidaiyah).

Global social inequality remains one of the fundamental challenges in the contemporary world economic system. The dominance of capitalist economic structures, which emphasize growth and capital accumulation, has proven effective in stimulating economic progress; however, it has simultaneously widened the gap between wealthy and disadvantaged groups at both national and global levels. Meanwhile, socialist economic systems that prioritize income equalization continue to face limitations related to efficiency and innovation. This article aims to examine the role of Islamic economics as an alternative economic framework capable of addressing the challenge of global social inequality. The study employs a qualitative descriptive approach through a literature review of classical and contemporary sources related to global economic systems. The findings indicate that Islamic economics offers a more balanced paradigm by integrating principles of distributive justice, ethical values, and social responsibility within economic activities. Instruments such as zakat, infaq, sadaqah, waqf, along with the prohibition of riba and other exploitative economic practices, serve as essential mechanisms for reducing social inequality. Therefore, Islamic economics holds significant potential as both a normative and practical solution for promoting sustainable global economic justice.

This study aims to analyze the implementation of gender-based public policy through the Child-Friendly School Program at SDN 01 Bendosari, Plantungan District, Kendal Regency. This research employed a descriptive qualitative approach using in-depth interviews, observation, and documentation as data collection techniques. Data analysis was conducted using the public policy implementation model proposed by George C. Edwards III, which emphasizes four key variables: communication, resources, implementers’ disposition, and bureaucratic structure. The findings reveal that the implementation of the Child-Friendly School policy at SDN 01 Bendosari has been carried out through an integrative approach by incorporating child-friendly principles into existing school programs and culture. Effective policy communication and positive implementers’ disposition, particularly among teachers and the school principal, have supported the implementation process. However, limited financial resources remain a major obstacle to fully optimizing the policy implementation. This study concludes that successful public policy implementation depends not only on regulatory frameworks but also on resource availability, implementers’ commitment, and institutional capacity to adapt policies to local conditions.

It can be concluded that the expatriate involvement policy will provide optimal benefits if it is implemented consistently with GCG principles and accompanied by a strong commitment to strengthening local managerial capacity.

Psychological well-being is a fundamental construct in individual development; however, within guidance and counseling practice it is often positioned merely as an indirect outcome of problem-focused interventions. Philosophically and empirically, psychological well-being holds substantial potential to be established as a primary goal of guidance and counseling services. This article aims to examine psychological well-being as an axiological objective of guidance and counseling through a philosophy of science perspective supported by recent empirical evidence. The method employed is a literature review of scholarly publications from the last eight years retrieved through Google Scholar. Eleven relevant articles were selected and analyzed using thematic synthesis to identify conceptual patterns and empirical findings related to psychological well-being in the context of guidance and counseling. The results indicate that psychological well-being is conceptualized as a long-term developmental outcome reflecting holistic human functioning, encompassing dimensions such as autonomy, purpose in life, personal growth, environmental mastery, self-acceptance, and positive relations with others. Various guidance and counseling interventions particularly those based on mindfulness and positive psychology interventions have been empirically demonstrated to effectively enhance eudaimonic well-being. From an axiological perspective, psychological well-being possesses strong value foundations and aligns with the ethical mandate of guidance and counseling to promote optimal human development. This article underscores the necessity of a paradigm shift in guidance and counseling practice, moving from a predominantly problem-oriented approach toward a well-being-oriented framework in which psychological well-being is positioned as a central and explicit goal of professional services.  

This study aims to examine the effect of contextual learning on students’ learning motivation in Indonesian language learning for second-grade students of Madrasah Ibtidaiyah (MI) Salafiyah 1 Kauman. Contextual learning is an instructional approach that connects learning materials with students’ real-life experiences, which is expected to increase their engagement and learning motivation. This study employed a quantitative approach with an experimental research design. The subjects of the study were second-grade MI students divided into an experimental class and a control class. Data were collected through learning motivation questionnaires and classroom observations during the learning process. The collected data were analyzed using statistical techniques to determine differences in learning motivation between the two groups. The results indicate that contextual learning has a positive and significant effect on students’ learning motivation in Indonesian language learning. Students who were taught using contextual learning showed higher learning motivation than those who were taught using conventional learning methods. Therefore, contextual learning can be considered an alternative instructional strategy to enhance students’ learning motivation at the elementary or Madrasah Ibtidaiyah level.

The results of this study are expected to provide practical implications for schools and parents in strengthening students’ preparation for the world of work

Intellectual Property Rights (IPR) are the result of human thought that have economic and social value and play a significant role in encouraging creativity, technological innovation, and sustainable national development. IPR protection not only aims to provide legal certainty for creators and rights holders, but also serves as a strategic instrument in strengthening the creative economy. However, low public awareness of the importance of IPR protection and the gap between legal norms and practices in the field result in frequent violations of intellectual works. This study uses a normative-juridical approach combined with a participatory-educational approach, in accordance with the characteristics of community service activities in the legal field. This approach aims to integrate normative legal analysis with legal education activities for the community, thereby producing both conceptual understanding and practical benefits. The results of the activities show a significant increase in public understanding of the relationship between constitutional principles and IPR protection in Indonesia. Through educational activities and legal dialogues, it was revealed that the integration between constitutional principles and the IPR legal system has not been optimal, not only due to limited regulations, but also weak public legal awareness and the application of substantive justice as mandated by the 1945 Constitution. These findings emphasize the importance of integrating constitutional values ​​in the IPR protection system.

This seminar featured two credible expert speakers in the field of entrepreneurship. The implementation method focused on interactive delivery of material, followed by a focused discussion session to maximize knowledge absorption. The results achieved showed a significant increase in understanding among participants, not only regarding the importance of instilling an entrepreneurial mindset but also mastery of practical aspects of business, including digital marketing implementation strategies and concrete steps in starting or developing a business unit. Through this intervention, PkM is expected to be able to provide a real contribution to accelerating the creation of new, innovative entrepreneurs and strengthening the sustainable entrepreneurial ecosystem in East Java

Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare, life-threatening mucocutaneous reactions characterized by extensive epidermal necrolysis and mucosal involvement. The entities represent a clinical continuum distinguished by the extent of epidermal detachment (SJS <10% body surface area [BSA], SJS/TEN overlap 10–30%, TEN >30%). Most cases are drug-induced, making early culprit-drug withdrawal and structured supportive care the cornerstones of management. Immunopathogenesis is primarily mediated by drug-specific cytotoxic T cells and NK cells through granulysin, Fas–Fas ligand, and perforin/granzyme pathways, with emerging roles of necroptosis and candidate biomarkers such as RIP3 and galectin-7. Diagnosis relies on timely recognition of the characteristic painful erythematous/targetoid lesions, Nikolsky/Asboe–Hansen signs, multi-site mucositis, accurate BSA assessment, and early severity scoring (e.g., SCORTEN) to guide referral and monitoring. Systemic immunomodulators (corticosteroids, cyclosporine, IVIg, anti-TNF agents) have variable evidence; thus, individualized selection and early multidisciplinary care particularly ophthalmologic involvement are essential to reduce acute mortality and long-term sequelae.

The rapid development of artificial intelligence (AI) in the medical field has become an important part of the learning process and health services. Preparing medical students as future healthcare professionals to understand, use, and implement AI responsibly is a crucial aspect. This level of readiness can vary depending on their knowledge, abilities, perceptions, and ethics in using AI. This study aims to determine the readiness of young medical students in the Surabaya area in using artificial intelligence based on these four domains, and to compare scores between first-year professional students and undergraduate students. This study used a quantitative descriptive design with a cross-sectional approach. The instrument used was the Medical Artificial Intelligence Scale for Medical Students questionnaire, which consists of four domains: knowledge, abilities, perceptions, and ethics. The study sample was first-year and second-year professional students of the Faculty of Medicine, Ciputra University. Data analysis was performed using descriptive statistics including mean values, standard deviations, and frequency distributions for each domain. The results showed that the total readiness scores for DM1 (89.95 ± 11.84) and DM2 (88.38 ± 8.85) showed a positive picture, with minimal mean differences. The knowledge and skills domain showed almost uniform values ​​between the two groups, while the ethics domain had the highest stability with a very small mean difference. These findings indicate that the readiness of professional students at the Faculty of Medicine, Ciputra University, towards the use of AI shows a positive and relatively even picture at all levels.  

General practitioners play a crucial role in the delivery of healthcare services in public hospitals, where limited organizational resources and high service demands often place significant pressure on medical personnel. These conditions may disturb work–life balance, increase the risk of burnout syndrome, and ultimately lead to higher turnover intention. This study aimed to analyze the effect of work–life balance on turnover intention, with burnout syndrome acting as an intervening variable among general practitioners at RSUD Balaraja. An observational analytic design with a cross-sectional approach was applied, involving all 40 general practitioners working in the emergency department and inpatient units through a total sampling technique. Data were collected using standardized instruments, namely the Work–Life Balance Scale, Maslach Burnout Inventory, and the Intention to Quit Questionnaire. Data analysis was conducted using Spearman correlation and Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results revealed a significant relationship between work–life balance and burnout syndrome, as well as between work–life balance and turnover intention. Burnout syndrome was also significantly associated with turnover intention. Further analysis showed that work–life balance had both direct and indirect effects on turnover intention, with burnout syndrome partially mediating this relationship. In conclusion, work–life balance and burnout syndrome are important determinants of turnover intention among general practitioners. Therefore, hospital management should prioritize strategies such as workload regulation, enhanced organizational support, and burnout prevention to retain medical staff and maintain the quality of healthcare services in public hospitals.

Excessive alcohol consumption, including traditional alcoholic beverages such as Cap Tikus  (alcohol content ±45%) from North Sulawesi, can induce liver damage characterized by steatosis, inflammation, and necrosis. Leilem leaf (Clerodendrum minahassae) extract, rich in phenolic and flavonoid compounds, has potential hepatoprotective effects due to its antioxidant properties. To evaluate the effect of leilem leaf extract on the histopathological features of the liver in Wistar rats (Rattus norvegicus) induced by Cap Tikus alcoholic beverage. This experimental study used a post-test only control group design with 24 male Wistar rats divided into four groups: normal control, negative control (Cap Tikus 2.16 mL/day), treatment I (leilem extract 150 mg/kgBW + Cap Tikus), and treatment II (leilem extract 300 mg/kgBW + Cap Tikus). Treatments were administered orally for 14 days. Liver tissue was processed for histopathological examination using hematoxylin-eosin staining and observed under a light microscope. The negative control group showed significant steatosis and inflammatory cell infiltration. Treatment groups exhibited reduced steatosis and inflammation, along with increased hepatocyte regeneration. The higher dose (300 mg/kgBW) demonstrated greater hepatoprotective effects and more prominent regeneration compared to the lower dose (150 mg/kgBW). No necrosis or fibrosis was observed in any group. Leilem leaf extract exerts a hepatoprotective effect by suppressing inflammatory responses and enhancing hepatocyte regeneration in Wistar rats induced with Cap Tikus. The highest protective efficacy was observed with leilem leaf extract at 300 mg/kgBW.
