<![CDATA[This research assesses the environmental impact of tourism and industry on Tanjung Pinggir Beach, Batam, with a focus on sustainable tourism. The method used was a mixed design, starting with collecting quantitative data through questionnaires from 10 tourists, followed by semi-structured interviews with 5 key informants. The results showed that 70% of participants felt that tourism activities caused pollution. The Clean Coast Index (CCI) received a score of 65, and the Marine Debris Index showed 12 items/m², indicating a decline in ecosystem quality. Analysis using the DPSIR framework and tourist behavior theory shows that there is a gap between environmental awareness and waste disposal practices. Research suggests collaboration between stakeholders through digital platforms. The theoretical contribution is the development of DPSIR in Southeast Asia, while the empirical contribution supports the use of CCI as a measuring tool. Limitations of the study were the small sample size and focus on one location; recommendations for future research are longitudinal studies and the application of monitoring technology.]]>
