Speaking, reading, listening, and writing are the four skills that students must master in English. But, of all these skills, students must first master vocabulary. This research was focused on investigating the effectiveness students' vocabulary mastery using comic "Donald Duck" for 7th grades student in SMP N 25 Semarang. The objective of this research was to compare the findings of students' vocabulary mastery before and after being taught Donald Duck comic media and to see if there was a significant difference in student achievement in their vocabulary mastery taught before and after using Donald Duck comic media. This research used a quasi-experimental design with two classes: experimental and control. This study's population consisted of 261 students in the seventh grade at SMP N 25 Semarang, and the sample consisted of 64 students from two classes, VIG and VID. Data was collected by giving a pre-test and a post-test, and then analysed in the SPSS program using the t-test formula. The results of the analysis show that students who are not taught to use comics have a "poor" ability, which can be seen from the results of their post-test average score of 60.13. While students who were taught to use comics had "good" abilities, it could be seen from the results of their post-test average score of 75.50. so, a t-test of 13,054 is obtained with a t-table of 2,042 at a significance level of 5%. it can be concluded that the t-test is higher than the t-table (13.054>2.042). This shows that there is a significant difference in vocabulary mastery between students who are taught using Donald Duck comics and those who are not taught using Donald Duck comics. which means the alternative hypothesis (Ha) is accepted and the null hypothesis (Ho) is rejected. it can be concluded that learning vocabulary mastery using Donald Duck comics is effective.
