Community participation refers to the active involvement of citizens in various stages of the development process, especially at the village level. A concrete example of community participation can be seen in the case study of Bendhung Lepen, located in Mrican Village, Yogyakarta. Bendhung Lepen is an irrigation canal that stems from the Gajah Wong River. Before its revitalization, the area faced numerous environmental problems, primarily due to household waste and pollution that contaminated the waterway and negatively affected the environment and public health. In response to these issues, local residents, along with relevant stakeholders, initiated an environmental conservation program. The main goal of this initiative was to restore the ecological function of Bendhung Lepen and transform it into a clean, green, and beneficial public space for the community. This study aims to measure the level of community participation in the environmental conservation program. Data collection methods included questionnaires for quantitative analysis and in-depth interviews for qualitative insights into community involvement. The results of the study show that community members were actively involved in various phases of the program, including planning, implementation, and evaluation. Stakeholders involved in the program included community leaders, youth groups, environmental organizations, and village officials. The forms of participation extended beyond voicing aspirations to contributing labor (through mutual cooperation) and materials (such as donations or supplies). According to Arnstein’s ladder of participation, the level of community participation in this conservation program falls under the category of "delegated power," which represents a high degree of participation. This means that the community was not merely involved as passive participants but was given real authority in decision-making and program management. These findings indicate that genuine and sustained community involvement plays a crucial role in the success of local environmental conservation efforts.

Teachers face complex emotional challenges in the workplace, particularly when dealing with the dynamic nature of Generation Z students. Without adequate emotional regulation skills, teachers are at risk of prolonged stress and burnout. This community service activity aims to improve teachers' emotional regulation skills through training based on Gross's (2003) theory, which includes techniques for recognizing, managing, and responding to emotions adaptively. The activity was conducted at SMK Muhammadiyah 1 Palembang and attended by 30 teachers. The training method included delivering material and practicing emotional regulation in six structured sessions. Results showed that participants were enthusiastic, actively engaged in the practice, and acknowledged their increased understanding and skills in managing negative emotions. Participant reflections indicated that the training helped maintain mental health and increased readiness to face work pressure. In addition, the sessions fostered a supportive environment where teachers could share their emotional experiences and develop mutual empathy. Feedback from participants emphasized the relevance of emotional regulation in daily teaching tasks, including classroom management, dealing with students’ behavior, and interacting with colleagues and parents. However, challenges remain in implementing emotional regulation due to minimal institutional support and limited follow-up programs. Therefore, it is important for this type of training to be integrated into teacher professional development programs and supported by school policies. This activity demonstrates that strengthening teachers' emotional aspects is a strategic step in improving the overall quality of education. Future efforts should involve collaboration with school leadership to institutionalize emotional support mechanisms and conduct longitudinal evaluations to measure sustained impact. Overall, the training offers a promising model for enhancing teacher well-being and professional resilience in demanding educational environments.

Diabetic foot ulcers represent one of the most serious long-term complications associated with type 2 diabetes mellitus, often contributing to increased rates of morbidity and mortality, while significantly impairing patients' quality of life. Among the various underlying causes, peripheral neuropathy and vascular disorders (vasculopathy) are frequently linked to dyslipidemia. This study aimed to examine the characteristics of total cholesterol and triglyceride levels, along with the prevalence of diabetic foot ulcers in patients with type 2 diabetes mellitus. A descriptive retrospective approach was used by analyzing medical record data collected from Dr. H. Chasan Boesoirie General Hospital in Ternate. The findings indicated that the majority of patients with type 2 diabetes were aged 45 years or older (80%) and were predominantly female (60%). In terms of lipid profiles, most patients exhibited normal total cholesterol levels (82.2%) and normal triglyceride levels (51.1%). Despite these normal lipid values, a significant portion of the patients (53.3%) were identified as being at risk of developing diabetic foot ulcers. These results suggest that while dyslipidemia is commonly implicated in the development of diabetic foot complications, normal lipid levels do not necessarily eliminate the risk. The study concludes that the typical profile of type 2 DM patients includes those aged ≥ 45 years, females, and individuals with normal cholesterol and triglyceride levels who are still susceptible to diabetic foot ulcers. This highlights the multifactorial nature of diabetic foot ulcer development and underscores the importance of comprehensive risk assessments beyond lipid profile evaluation alone in diabetic patient care.

Community-based servant leadership development has emerged as a critical approach for Christian nonprofit organizations seeking to cultivate authentic leaders who embody Christ-centered values. This study explores the integration of theological foundations from Mark 10:45 with Robert K. Greenleaf's servant leadership theory to develop a comprehensive model for leader formation within Christian nonprofit contexts. Employing a qualitative methodology with a library research design, data were collected from scholarly literature and theological sources, then analyzed using Miles and Huberman's interactive model, which includes data reduction, data display, and conclusion drawing. The research reveals a significant alignment between the core message of Mark 10:45—“For even the Son of Man did not come to be served, but to serve”—and the key principles of Greenleaf’s servant leadership, particularly the emphasis on selfless service, empathy, listening, and community building. Community plays a vital role as both a laboratory and an incubator for spiritual and leadership formation, where individuals can internalize leadership values through biblical teaching, mentorship, active religious practices, and shared life experiences. The study proposes a five-stage model: Foundation Building, Community Immersion, Skill Development, Practical Application, and Leadership Multiplication. This model serves as a strategic guide for Christian organizations to intentionally nurture servant leaders. Findings highlight improvements in character formation, organizational effectiveness, and the embodiment of servant leadership traits such as humility, sacrifice, and empathy. The study concludes with practical recommendations for implementation, including structured mentoring systems, the formation of communities of practice, and ongoing evaluation mechanisms. Ultimately, this integrated model supports the mission of Christian nonprofits by shaping leaders who advance both spiritual and social transformation.
