This study aimed to determine the improvement of the Environmental Epidemiology Subject's learning outcomes through Two Stay Two Stray (TSTS) and Co-op Co-op learning model strategy. This study was a classroom action research and compared the scores in the semester of the academic year 2018/2019 (conventional class) and 2019/2020 (learning model strategy). This study's subjects were 45 fourth grade students. The average midtest score obtained by students was increasing with 72.07. From the results of the t-test, it is obtained that the t-count at 2.94 is higher than the t-table of 2.026. This data showed that the learning outcomes of students increased significantly compared to conventional. Based on these results, it can be concluded that the TSTS and Co-op Co-op that was the model that invites the students to be active through the group in the learning activities.
