Natural disasters (floods) can cause psychological impacts and potential public health hazards. Children carrying out daily activities will be disturbed, including learning, fear, and remembering the flood under normal conditions. Children need mental health and psychosocial support, which are essential in creating and supporting states that allow optimal growth and welfare of children in disaster situations. Deket Sub-district, one of the sub-districts in Lamongan Regency, is a frequent flood. Sidomulyo Village has the highest flood height, with water levels between 15 to 37 centimeters in 2022. SDN Sidomulyo 1 is one of the schools affected by this annual flood.
