Children's education is the main foundation for building the nation's generation, however parental involvement in coastal areas still faces significant challenges due to economic busyness, low parenting literacy, and unsupportive social environmental influences. This community service aims to strengthen the role of parents in children's education and character building through the synergy of family, school, and community in Labuhan Village, Lamongan Regency. The method used is Participatory Action Research (PAR) with five stages: problem identification, planning, implementation, evaluation, and reflection. The main programs include Parenting Seminars, teacher-parent communication forums, and storytelling activities involving 80 parents and all students from four elementary education institutions. The results showed an increase in parental awareness in accompanying children, marked by increased shared learning time at home, more intensive communication with teachers, and more consistent moral support. Children also showed positive changes in the form of increased discipline, responsibility, and learning motivation. The novelty of this community service lies in the contextual application of the PAR approach in coastal areas with fishing community characteristics, as well as the integration of three intervention programs simultaneously. The contribution of this community service is the availability of a community-based parental empowerment model that can be replicated in other coastal areas. In conclusion, active parental involvement contributes significantly to children's academic success and character building, so sustainable strategies are needed in the form of regular communication forums, simple parenting modules, and support from community leaders to maintain educational synergy in Labuhan Village
