Increasing population density and concretization in urban areas, such as Magelang City, have caused a significant decrease in green open spaces (RTH), which has an impact on food security and independence. Magelang City, with a population density of 7,361 people/km², faces a major challenge in providing adequate green spaces to support local food production. Rejowinangun Selatan Village, as one example, shows the limited green open spaces available. To overcome this problem, urban farming, especially through hydroponic techniques, offers an effective solution. The methods applied in this community service include various approaches to educate and directly involve the community in the practice of making hydroponics with solar panels. By utilizing renewable energy-based technology, such as solar panels and integrated electrical systems, hydroponic farming allows food production in limited spaces such as house terraces. This system not only increases food independence and security, but also ensures that the vegetables produced are healthier because of the minimal use of pesticides. Urban farming with the hydroponic method can optimize the use of limited space and become a productive and sustainable alternative for urban communities.

The southern district of Rejowingan in Magelang faces challenges like large dumpstores, poor water quality, floods, and rising food needs. Villagers are working with the Ormawa DPM KM PPK team to address these issues. The government launched the Climate Village Program to improve the region's climate and resilience to natural disasters. Permaculture principles can be applied to organic waste management through maggot cultivation, which reduces waste volume and supports sustainable agriculture. This combination of permaculture and maggot cultivation can be an effective and environmentally friendly model for addressing organic waste and ecosystem sustainability.
