The low level of foreign language proficiency, particularly in English, among Micro, Small, and Medium Enterprises (MSMEs) in Banda Aceh and Aceh Besar is one of the obstacles to supporting sustainable tourism development, especially in serving foreign tourists. This community service activity aims to improve the functional English language skills of MSME actors in order to strengthen the community-based and sustainable tourism services. The implementation method used a participatory approach based on the needs of partners, including hands-on practice and mentoring. The material focused on Aceh tourism vocabulary, everyday communicative expressions, and cross-cultural communication strategies in tourist interactions, product promotion, and customer service. This activity involved 10 MSME actors around the tourist areas of Banda Aceh and Aceh Besar. The results showed a significant improvement in the participants' English language skills and increased confidence in offering products and services. The output was an increase in the capacity of MSME human resources and the strengthening of their role in the sustainable tourism ecosystem based on local Acehnese wisdom. This activity has the potential to be replicated as a model of applied foreign language education for MSME actors in other tourist destinations in Indonesia.
