Background: The COVID-19 problem that has been declared by WHO as a global pandemic since March 2020 has not only had impacts to the health, but also to Micro, Small and Medium Enterprises (MSMEs). Cilok Goreng Setiabudi is one of the MSME actor that sel ected for community empowerment. The purpose of the study: to strengthen the behavior of the workers towards COVID-19 preventions. Method: This study used a qualitative method based on the Health Belief Model (HBM) theory through in-depth interviews with 15 informants of the workers. The interviews were via the Zoom application that had been done personally. Result: Most of the workers got the basic knowledge of COVID-19 from news on television. The perception of vulnerability was only felt by five sellers which required them to meet many people in their work. Almost all workers felt the threat of COVID-19 which impacted on their economic activities. There were barriers in implementing the health protocol such as wearing masks and keeping the distance. The workers perceived the benefits of implementing health protocols, but only few of them knew the benefits of vaccines. All workers felt confident that by implementing the health protocols, they can avoid the COVID-19 disease. Cues to implement the health protocols was from their family and the community leaders. To strengthen COVID-19 prevention behavior, informal interventions were carried out through online group health education, discussions and quizzes at the end of the meeting with the result of 74.8% accuracy. Conclusion: The workers always implement health protocols in daily practice, but still some of them do not discipline in practicing COVID-19 prevention, therefore, educational intervention was carried out for workers in order to strengthen the behavior towards COVID-19 preventions to this MSME. © 2022 MPPKI.
