Abstract

Sugihmanik Village, a major tofu production center, produces substantial amounts of organic waste, particularly wastewater that contaminates local rivers and disrupts the surrounding ecosystem. A community service program has been developed to convert tofu waste sludge into maggot feed, followed by drying using a hybrid solar and gas-powered maggot drying machine. Initial activities involved program outreach and technical training on maggot cultivation and the drying process. A drying trial demonstrated that 200 grams of wet maggots were reduced to 114 grams within seven minutes. Monthly drying operations required only four 3-kg LPG cylinders, resulting in 81 kilograms of dry maggots and a potential monthly income of IDR 4.050.000. Environmental degradation caused by tofu waste has been significantly mitigated, while local economic productivity has improved. The drying machine enhances the commercial value of maggots as durable livestock feed. The initiative strengthens the operational sustainability of the Krida Manik Waste Bank and offers a scalable model for resource-based environmental solutions.

Abstract

As the capital of Malaysia, Kuala Lumpur has not escaped various environmental issues that have worsened due to rapid urbanization, ranging from air pollution to insufficient waste management. This condition requires a creative solution to foster awareness of sustainability from a young age. In response, a community service program titled "Education for Environmental Conservation through the Introduction of Biopori for Elementary School Students at the Kuala Lumpur Learning Studio" was present to introduce the concepts and benefits of biopori technology to children aged 6 to 12. Its main goal is to build early awareness of environmentally friendly practices, especially in flood prevention and organic waste management. Methods used in the program vary widely and interactively, including storytelling, exciting visual presentations, educational games, and video demonstrations. The implementation of this program also collaborates with the Kuala Lumpur Indonesian School (SIKL), which ensures the harmony of culture and education with the target students. The results of the program showed a significant improvement in students' understanding and interest in biopore technology. Many of them are enthusiastic about implementing biopore at home, reflecting expected positive behavioral changes. Post-activity feedback from students and facilitators indicated high levels of engagement and enthusiasm. This initiative demonstrates the effectiveness of early environmental education in building eco-conscious habits. It supports the advancement of community-based science education and contributes directly to the Sustainable Development Goals (SDGs), particularly in clean water and sanitation (Goal 6) and climate action (Goal 13). The program offers a scalable model for integrating environmental awareness into urban education systems.

Abstract

This community service activity was carried out by a team of lecturers and students of Yogyakarta State University (UNY) in Tlahap Village, Kledung District, Temanggung Regency, specifically in the Posong Nature Tourism area. The background of this activity was the limited access to electricity faced by the community managing food courts in the tourist area due to the lack of optimal PLN network coverage. This has an impact on low service quality, limited stall operating hours, and lack of comfort for tourists. Therefore, the community service team presented a renewable energy-based solution in the form of a hybrid system of Solar Power Plants (PLTS) and wind turbines with a capacity of 1,500 watts and 5,000 Wh of energy storage. The method of implementing the activity was carried out through an energy needs survey, socialization, device installation, technical training, and monitoring and evaluation. The community service activity was carried out on August 8, 2025, at 10:00 WIB until finished, attended by the Head of Tlahap Village, the Chairperson and management of Posong Nature Tourism, and 23 local residents, with cloudy and foggy weather conditions but proceeded smoothly. Participants were given an understanding of renewable energy systems, maintenance techniques, handling electrical short circuits, and power usage management to prevent batteries from draining quickly. The results of discussions with the community showed that the application of renewable energy not only provides a solution to electricity needs, but also increases the community's capacity to manage electrical engineering systems independently. Furthermore, the availability of electricity supports the development of food court businesses, tourist comfort, and strengthens Posong's image as an eco-tourism destination. This activity contributes to the achievement of the Sustainable Development Goals (SDG 7: Affordable and Clean Energy, SDG 8: Decent Work and Economic Growth, and SDG 13: Addressing Climate Change).
