The rapid development of digital technology requires micro, small, and medium enterprises (MSMEs) to utilize social media as an effective marketing tool to enhance competitiveness and business sustainability. However, many MSME actors still face limitations in knowledge and skills related to the optimal use of online marketing strategies. This community service activity aimed to improve the knowledge and understanding of MSME actors regarding online marketing using social media. The activity was conducted in the form of training and interactive discussions held offline in Cempaka Putih District, Central Jakarta, involving 57 MSME participants. The implementation methods included lectures, discussions, and question-and-answer sessions covering digital marketing strategies, social media utilization, product packaging, and MSME business management. The results showed that participants experienced increased understanding of the importance of digital marketing and the use of social media as a promotional medium. Participants also demonstrated enthusiasm and readiness to apply online marketing strategies in their respective businesses. This activity had a positive impact on enhancing the capacity of MSME actors to expand market reach and improve business competitiveness. However, follow-up activities in the form of practical training and continuous mentoring are needed to ensure the optimal and sustainable implementation of digital marketing strategies.
