This study aims to determine the effect of the use of audio-visual media based on local wisdom on improving poetry writing skills in class X students. The method used is a quasi-experimental design with a nonequivalent control group design. This research was conducted during the even semester of the 2025/2026 academic year at SMK PGRI 2 Cianjur. The research subjects consisted of two classes, namely the experimental class that used audio-visual media based on local wisdom and the control class that used conventional media. The research population was 30 class X students who took the pretest and posttest on their ability to write poetry. There were 14 students in the control group and 16 students in the treatment group. The sample was determined to be 28 students based on a statistical formula drawn at simple random using a non-replacement technique. Data collection techniques were carried out through tests (pretest and posttest). Data analysis used statistical tests to determine differences in learning outcomes between the two groups. The results showed that there was a significant increase in students’ poetry writing skills in the experimental class compared to the control class. This was indicated by the higher average posttest score of the experimental class and the results of statistical tests that showed a significant difference. The use of audio-visual media based on local wisdom was proven to be able to increase learning motivation, enrich imagination, and help students in choosing diction and developing ideas more creatively. Based on the research results, it can be concluded that the use of audio-visual media based on local wisdom is effective in improving the poetry writing skills of class X students.
