This research aims to analyze the role of the National Professional Certification Agency (BNSP) thru the Balawista certification program (Water Tourism Rescue Agency) in supporting the achievement of Sustainable Development Goals (SDGs) in the marine tourism sector of Banten Province. Banten Province has great potential for marine tourism with 82 beaches along a 509-kilometer coastline, but the high number of accidents in the waters highlights the urgency of strengthening a competency-based safety system. The research uses a descriptive qualitative approach with data collection techniques including in-depth interviews, direct observation, and documentation studies involving eight key informants from local government, BNSP, LSP, and tourism destination managers. Data analysis refers to George C. Edwards III's policy implementation theory, which includes the variables of communication, resources, disposition, and bureaucratic structure. The research results show that Balawista certification significantly contributes to four SDG goals, namely SDG 3 (Health and Well-being), SDG 8 (Decent Work and Economic Growth), SDG 11 (Sustainable Cities and Communities), and SDG 14 (Life Below Water). However, out of a total of around 450 Balawista members in Banten, only about 150 have official competency certificates. The implementation of certification is still hindered by budget constraints, limited access to LSP in the regions, low socialization, and a lack of economic incentives for certified personnel. Strengthening Balawista certification requires integrated collaboration between BNSP, local governments, LSP, and destination managers within the framework of collaborative governance to realize safe, professional, and sustainable marine tourism.
