Indonesia's oceans as the heart of the Coral Triangle face a serious threat from anthropogenic pressure in the form of plastic waste pollution in coastal areas. The Mayangan Coastal Fisheries Port (PPP) is one of the epicenters of complex waste flows from land and sea activities. As a solution, MYG+ innovation, a community-based holistic upstream waste management model and circular economy is implemented. This study aims to analyze the reduction in the volume of waste around the Mayangan PPP after the implementation of MYG+, examine the response of fishermen, and evaluate the success rate and recommendations for improvement. The research method uses a qualitative and quantitative descriptive approach (mixed-methods) through the principle of holistic management. Waste volume data was analyzed comparatively before and after the program, while fishermen's response and success rate were evaluated through field surveys. The results show that MYG+ innovation significantly reduces the volume of waste in port areas through efficiency of prevention upstream and strict sorting downstream (composting and recycling). This reduction in pollution burden directly contributes to improving water quality, restoring ecosystems (coral reefs and seagrasses), and increasing fish populations. Socially, this program received a positive response and encouraged a change in less-waste behavior from the fishing community. This study concludes that the MYG+ model is effective as a best practice for integrated coastal area management. The implications of this study provide an empirical contribution to the community-based waste management literature as well as a guide for policymakers to replicate similar models in other fishing ports in Indonesia.
