Early character education plays a fundamental role in shaping a generation that is not only intelligent but also physically healthy, emotionally balanced, and morally responsible. The cultivation of these values from an early age is crucial to equip children with the resilience needed to face various social challenges in the future. This community service activity was designed to increase awareness among elementary school students regarding three critical issues: the dangers of drug abuse, the practices of bullying, and the detrimental impact of corruption. The program was conducted at SDN 1 Citeluk with the participation of approximately 80 students from grades IV to VI. The educational materials were delivered through an interactive approach combining lectures, group discussions, role-playing, and quizzes. This approach was selected to ensure that the learning process was enjoyable, engaging, and easily understood by children at the elementary school level. During the sessions, students were introduced to the basic concepts of drugs, their harmful effects on health and life, and the importance of avoiding them. Additionally, the program emphasized identifying the various forms of bullying—whether physical, verbal, or social—and encouraged students to develop empathy and mutual respect. Another important aspect addressed was corruption, where students were guided to recognize the value of honesty and integrity through relatable examples in daily life. The results of the activity revealed that students were able to clearly understand the dangers of drugs, recognize the different forms of bullying, and provide examples of honest and moral behavior. This indicates that early character education delivered through interactive and participatory methods can effectively enhance children’s comprehension of healthy and moral values. It is expected that similar programs can be carried out sustainably in elementary school settings as part of continuous character-building efforts to support the development of a responsible and ethical young generation

Batteries are the primary component in electric motorcycle propulsion systems, playing a crucial role in storing and supplying energy. However, batteries have a limited lifespan, potentially becoming waste after their useful life. Battery waste is categorized as hazardous and toxic waste (B3) because it contains heavy metals and chemical compounds that can negatively impact human health and the environment if not managed properly. As the adoption of electric motorcycles increases in Indonesia, particularly in the Special Region of Yogyakarta (DIY), the issue of battery waste management is becoming increasingly important. Currently, there are no electric motorcycle manufacturers openly willing to manage post-life battery waste, particularly through recycling activities. This situation creates a gap that informal actors could potentially exploit. Informal actors often possess flexibility and basic technical skills, but their capacity to manage battery waste safely and sustainably still needs to be mapped and strengthened. This study focused on mapping the potential capabilities of informal actors in the Special Region of Yogyakarta by 2025. The results indicate that the potential for informal actors capable of providing battery repair services is only around 1%. This figure is very small and therefore insufficient to support future battery waste management needs. Therefore, multi-stakeholder support is needed, from the government and manufacturers to the community, to encourage capacity building among informal actors. This effort is crucial to anticipate the success of the government's 2030 target for electric vehicle conversion, while also ensuring environmental sustainability.

Personal financial management is an essential skill that needs to be instilled from adolescence to foster healthy and responsible financial behavior. Teenagers are often faced with situations where they must make decisions regarding money, but a lack of understanding and education about finances often leads to consumptive behavior, wastefulness, and a lack of ability to save. However, poor financial habits developed early on can carry over into adulthood and impact a person's future financial situation. Through a Community Service activity conducted by lecturers from the Faculty of Economics and Business, Wijaya Kusuma University, Surabaya (FEB UWKS) at SMA Negeri 2 Mojokerto, students were provided with education on accounting-based personal financial management. The material presented covered basic accounting principles, the importance of recording income and expenses, and how to prepare a personal financial budget. The activity methods included counseling, financial recording simulations, budget preparation, and interactive discussions, designed to encourage active participation and practical understanding. The results of the activity showed that students experienced a significant increase in understanding of the importance of financial literacy. They were also able to prepare a simple budget based on needs and priorities using a basic accounting approach. Thus, this activity is expected to make a real contribution to shaping the character, responsibility, and financial independence of the younger generation. Furthermore, similar activities can be extended to other schools to raise financial literacy awareness among students more broadly and sustainably. Furthermore, the involvement of teachers and school administrators in supporting this financial literacy program is also a crucial factor in maintaining students' desire to understand. With synergy between academics, schools, and students, financial education can become an integral part of the learning process, focusing not only on theory but also on practical application in everyday life.

The provision of clean water is a basic necessity and a fundamental responsibility of the government as a form of public accountability. Clean water not only plays a crucial role in supporting daily life but also directly affects public health, education, and economic productivity. However, the condition in Tanjung Melagan Island, located in the hinterland area of Batam City, still shows serious issues regarding access to clean water. Limited infrastructure, remote geographical location, and the lack of policy intervention are the main obstacles faced by the local community. This study aims to analyze the responsibility of the Batam City Government in providing clean water using J. Spiro’s accountability theory, which highlights three main indicators: accountability, obligation, and causality. This research employs a qualitative approach through in-depth interviews, field observations, and document studies. Informants in this study include officials from the Department of Human Settlements and Spatial Planning of Batam City, the Head of Galang Baru Subdistrict, and local residents of Tanjung Melagan Island. The results of the study indicate that the accountability of the Batam City Government in the provision of clean water has not been carried out substantively. Although formal forums such as Development Planning Meetings (Musrenbang) exist, their implementation remains procedural and does not fully absorb the aspirations and needs of the local population. The government's obligation to provide clean water is acknowledged normatively, but its realization often faces technical constraints, complex bureaucracy, and the delegation of responsibilities to non-governmental institutions. Furthermore, several underlying causes of this weak accountability were identified, including limited budgetary resources, poor inter-agency coordination, and low levels of community literacy and participation in planning and monitoring processes. Thus, this study emphasizes the importance of strengthening the role and capacity of local governments in providing essential services such as clean water, especially in underdeveloped and remote regions, to ensure that the principle of social justice is truly realized.
