Kata Kunci: Mangrove, Pesisir ABSTRACT Mangrove ecosystems have ecological functions that are very beneficial for organisms in the coastal environment, including humans. With a dense and sturdy root system and canopy, mangrove vegetation also functions as a land protector from wave action, tsunamis, hurricanes and seawater seepage. In addition, mangroves also function as nutrient providers, their ecosystems are spawning grounds, nursery grounds and feeding grounds for various types of fish, shrimp and other marine biota. The problem faced by the people of Labetawi Village is the lack of information and knowledge about the importance of mangrove ecosystems for fisheries and marine resources. The main cause of damage to mangrove forests in Indonesia is due to human actions, in the form of land conversion into community settlements and illegal logging. These mangrove forests can protect coral reefs, seagrass beds from the onslaught of land sedimentation, reduce erosion in coastal areas and protect beaches from the effects of waves, wind and waves. The implementation of community service activities that focus on mangrove rehabilitation is expected to be able to contribute to environmental restoration in Lebetawi Village, Tual City and increase public awareness of the importance of protecting mangrove ecosystems.
