The aims of this community service activity are to produce diversification and development of yogurt products from ettawa goat's milk. This service was carried out at UD Susu Kambing Ettawa, Karang Anyar Village, Langsa Baro District, Langsa City. The method of implementing this community service consists of the following stages: planning and preparation (team debriefing, pre-survey, determining the schedule and place of activity, preparation of tools and materials), implementation (counseling and workshops), as well as the monitoring and evaluation stage. Pretest and posttest on 15 participants were carried out to determine the level of adoption of the participants' knowledge regarding Ettawa goat milk diversification which was analyzed using the Wilcoxon Signed Test. The results of the planning and preparation stages have agreed on the tools and materials needed by the partners, the date and place of implementation, as well as the financing. The results achieved from the implementation stage were product diversification in Ettawa goat milk in the form of yogurt, packaging changes, branding (branding), and marketing using social media.
