This study aims to analyse the stakeholder cooperation model in sustainable marine ecotourism development at Tlangoh Beach, Bangkalan Regency, using the Penta Helix approach, which includes the roles of academia, business, community, government, and media. The background of this study is based on the great potential of Tlangoh Beach as a marine ecotourism destination that can boost the local economy while preserving the environment, but it faces challenges in the form of limited infrastructure, suboptimal waste management, and low integration of partnerships between parties. This study uses a qualitative descriptive method that prioritises the meanings and actions of stakeholders or actors involved in the management of marine ecotourism at Tlangoh Beach in Bangkalan Regency. Data collection was carried out through observation, interviews, and document review. Key informants included the relevant village government and the Bangkalan Regency Tourism, Culture, Youth, and Sports Office. The data analysis technique followed the four stages proposed by Miles Huberman & Saldana (2014), namely data collection, data reduction, data display, and conclusions. The results of the study show that the village government and the community (Pokdarwis) are the main drivers in destination management, while PHE WMO's CSR acts as a catalyst for development through the provision of tourist facilities, sustainable management training, and coastal conservation programmes. However, the contribution of academia, integrated digital promotion strategies, and external private investment is still limited. The conclusion of this study confirms that a cooperation model at Tlangoh Beach has been established but is still sectoral in nature, so it is necessary to strengthen cross-sectoral collaboration based on the Penta Helix in order to realise sustainable, inclusive, and adaptive marine ecotourism in the face of environmental challenges.
