Co-management is an alternative solution in the form of management that integrates the roles and interests of everyone in the mangrove rehabilitation program. This study aims to analyze the role and level of influence of the interests of each actor in mangrove rehabilitation activities in Langkat Regency. The research method uses descriptive-qualitative, data collected from the results of questionnaires, interviews; field observations are processed in the form described in the description on the tabulation. From the results of this study, the form of co-management in mangrove rehabilitation is at a consultative stage where the government begins to consider local views in the decision-making process, the level of participation of each stakeholder in the low category, so this study recommends that the form of participation of each stakeholder can be increased through the form of regulations together, a program of sustainability and systematic distribution of work that is socialized to every implementer of the mangrove rehabilitation program in Langkat District.
