<![CDATA[Handwashing is an effective method for preventing the spread of infectious diseases, but frequent use of commercial alcohol-based hand sanitizers may cause skin irritation and dryness. Therefore, safe and effective antiseptic alternatives are needed. Postbiotics derived from lactic acid bacteria offer promising potential because their metabolites, including organic acids, bacteriocins, and biologically active enzymes, can inhibit microbial growth while being potentially gentler on the skin. This Community Partnership Program (PKM) aimed to develop a postbiotic-based hand sanitizer from lactic acid bacteria, increase public awareness of safe and sustainable hand hygiene, and introduce microbiology-based innovation. The program involved PKK members through educational activities and practical introduction to postbiotic-based hand sanitizer. The results showed increased understanding and capabilities among participants regarding proper hand hygiene and the potential use of postbiotics as skin-friendly antiseptic agents. High participant enthusiasm indicated strong potential for sustainable implementation in promoting clean and healthy living habits and developing community-based health products. Continued implementation is recommended by strengthening PKK members’ skills and facilitating production by MSMEs while maintaining quality, safety, and regulatory standards for community-based production and wider adoption.]]>
