Abstract

This paper presents a community-driven agribusiness innovation that transforms Telaga Rena, a village reservoir in Doudo, East Java, into a productive space for floating agriculture. Responding to land scarcity and seasonal water limitations, the initiative integrates aquaponic systems using eco-friendly materials such as cocopeat and rice husks to cultivate vegetables and freshwater fish. The project exemplifies green innovation by optimizing underutilized water surfaces, reducing chemical inputs, and enhancing biodiversity. Through participatory planning and collaboration with local stakeholders, including youth groups, women’s collectives, and village tourism entities, the model fosters inclusive economic empowerment and environmental stewardship. The integration of floating agriculture with edu-tourism and digital documentation demonstrates the potential for scalable agribusiness that aligns with sustainable transformation goals. Findings suggest that floating agriculture not only improves food security and income diversification but also strengthens local resilience. However, the process revealed that innovation requires iteration; several trials and adjustments were necessary before reaching optimal system performance. The strong enthusiasm of local residents and support from multiple sectors proved essential in sustaining momentum and overcoming technical challenges. This study contributes to the discourse on green agribusiness, rural innovation, and the role of community agency in sustainable development
