The government is currently very concerned about efforts to reduce and prevent stunting. Growth that is below standard when aged less than 6 years is called stunting. One program to reduce stunting is providing healthy and nutrient-dense food, namely high protein, to children in posyandu activities. Posyandu members can produce healthy and nutritious food themselves in an effort to ensure product safety and hygiene and optimize the budget. The aim of this community service is to increase the knowledge and skills of posyandu women in Binakarya Village, Garut Regency in making fried fish balls (Basreng). Basreng is a nutritious food and is liked by children. The implementation method consists of two stages, namely seminars aimed at increasing knowledge and participatory plotting to improve the skills of activity participants. The activity will take place from January 5 2023 to February 6 2023, the strategic target audience is Posyandu cadre mothers.
