One of the policies to inform health and nutrition issues is the National Health Insurance Program (JKN), organized by the Health Social Security Administration (BPJS) under Law Number 40 of 2004 concerning the National Social Security System (SJSN). Although the coverage of JKN participation is increasing, it has not yet reached the Universal Health Coverage (UHC) target in the National Medium-Term Development Plan (RPJMN), which is 98% of the Indonesian population. So, this impacts the high nutritional issues of children under five in Indonesia, especially the suffering of stunting. The purpose of this study was to describe the ownership and utilization of JKN on stunting in West Sulawesi Province. The method in this study was a descriptive research design using SSGI 2021 secondary data in West Sulawesi Province. The results showed that the percentage of JKN ownership for stunting toddlers was 36.2%, while the utilization of JKN for stunting toddlers was 26%. The results of the study illustrate that JKN ownership is still high compared to JKN.
