Food security is one of the Islamic Social Finance Institution's strategic goals. The purpose of this research is to investigate the mechanism for implementing food security programs at Islamic social finance institutions in Pacitan, Indonesia. The study also revealed the role and impact of the food security program on people's food needs during the Covid-19 pandemic, which helped to achieve sustainable development goals. This is a descriptive qualitative study that relies on primary data from in-depth interviews. According to the study's findings, the implementation of the food security program begins with the collection of funds from infaq and shadaqah. Then, based on predetermined criteria, select beneficiaries who will receive basic food packages, purchase food, construct food barns, and distribute basic food assistance. This food security program's impact is to meet some basic food needs, reduce consumption spending, meet nutritional needs, and mitigate economic difficulties during the pandemic.
