Green Manufacturing Solutions in the Development of Sustainable Agro-edutourism in Semarang City, Indonesia

The agricultural sector faces significant challenges due to climate change and land conversion, threatening long-term food sustainability. This study aims to provide policy recommendations by applying the green manufacturing approach to optimize the potential of Mijen District as an agro-edutourism destination. The research began by identifying local resources in Kampung Sawah Mijen, one of the area’s key agricultural tourism sites, as a basis for developing strategic solutions through sustainable innovation. Participatory Rural Appraisal (PRA) was employed to explore the community's perspectives on potentials, problems, and solutions. Meanwhile, the Multiaspect Sustainability Analysis (MSA) was employed to assess the sustainability index across six dimensions. The results show that farmers produce an average of 4.6 tons of rice per hectare per growing season, with the majority already implementing environmentally friendly agricultural practices. The sustainability index of Kampung Sawah Mijen was 50.14, with the highest score in the social aspect (69.44) and the lowest in the technological aspect (41.67). Green manufacturing practices such as converting rice straw and manure into compost, reusing aquaculture waste for irrigation, and implementing energy efficient post-harvest techniques were introduced and evaluated as part of an agro-edutourism model. These initiatives were developed collaboratively with stakeholders, including local communities, academics, business, and the media. The findings highlight the need for sustainable technological innovation. Green manufacturing provides a practical pathway to enhancing farmers’ economic resilience while promoting sustainable production and education-based tourism in urban agricultural areas.
