<![CDATA[Local wisdom-based worksheets (LKPD) play a crucial role in learning activities. These local wisdom-based worksheets are expected to be utilized by teachers and students at SDK Mok to enhance their knowledge and learning outcomes in science. The purpose of this study was to determine the feasibility, attractiveness, and effectiveness of a local wisdom-based worksheet in improving student learning outcomes on the topic of the unique customs of the people around me. The type of research used is research and development, with the ADDIE (Analyze, Design, Development, Implementation, and Evaluation) development model. The data collection techniques used are test and non-test techniques. The data analysis techniques used are initial data analysis techniques and final data analysis techniques. The assessment of LKPD based on local wisdom was validated by three experts with the following results: material experts 80% (very feasible), language experts 97.5% (very feasible), and media experts 78.84% (very feasible). The trial was conducted on a limited basis with 10 students and expanded to 21 students. The results of the validity test showed that 15 questions were valid, reliable (α = 0.956 and α = 0.888), and had a good to very good level of difficulty and discriminatory power. Student learning outcomes increased, from an average pretest score of 60.95 to 91.66 on the posttest. The paired t-test showed a significance value of 0.000 <0.05, which means there is a significant influence of the use of LKPD on student learning outcomes. The N-Gain value of 0.7639 is included in the high category. Teacher responses to LKPD reached 87.5% with a very valid category and student response questionnaires with r counts of 0.490 to 0.867 with a valid category.]]>
