摘要

Access to freshwater remains a major challenge on small islands inhabited by the Bajau people, often resulting in inadequate sanitation and environmental degradation. This study explores the social acceptance and environmental implications of hybrid photovoltaic–electrodialysis–reverse osmosis (PV-ED-RO) desalination technology in Pasikuta Village, Southeast Sulawesi, Indonesia. The Bajau community’s social practices are shaped by limited infrastructure, restricted access to education, and unstable fishing-based incomes. Through semi-structured interviews with 151 household heads and grounded theory analysis, a conceptual framework was developed to capture community perceptions. The Technology Acceptance Model (TAM) and Analytical Network Process (ANP) were applied to assess social acceptance and environmental impacts. Results indicate that low educational levels and economic instability significantly influence willingness to adopt new technologies. Education emerged as a key factor in enhancing understanding of the PV-ED-RO system. TAM analysis showed that 65.6% of respondents expressed a favorable attitude toward adoption, though many still depend on rainwater. This proportion indicates a high level of social acceptance compared to similar studies on technology adoption in coastal communities, which commonly report moderate acceptance levels (50–60%). Environmental aspects (Ecosystem Sustainability (En-ES) and Health Impact (S-HI)) were prioritized, emphasizing the need to minimize ecological disruption and ensure safety. Integrating solar energy via PV enhances the feasibility of implementing this system in remote off grid regions. Understanding the interconnections among environmental, technological, social, and economic dimensions is crucial for tailoring desalination technologies to the unique characteristics of the Bajau community, ensuring long-term sustainability and community acceptance of freshwater solutions.
