<![CDATA[Introduction: Diabetes mellitus is a chronic disease that can cause various complications, one of which is diabetic foot ulcers. This complication can be prevented through proper foot care, but the success of prevention is greatly influenced by the patient's level of knowledge. Good knowledge allows patients to understand the risks, recognize early signs of wounds, and take preventive measures independently. This study aims to determine the relationship between the level of foot care knowledge and the prevention of diabetic foot ulcers in diabetes mellitus patients at the Lok Bahu Community Health Center in Samarinda. Methods: This study used a quantitative design with a cross-sectional approach with 70 respondents of diabetes mellitus patients selected through a purposive sampling technique.

The statistical test results showed a p-value of 0.045, indicating a significant relationship between the level of foot care knowledge and the prevention of diabetic foot ulcers.
