<![CDATA[The development of nationalism values among elementary school students requires contextual learning that is closely related to students’ daily lives. However, Pancasila Education learning is often dominated by lecture methods and textbook-oriented instruction, causing nationalism concepts to be perceived as abstract and less meaningful by students. This study aimed to determine the effect of integrating Wonosobo traditional sarong visual motifs as a local wisdom-based learning media in Pancasila Education on the development of nationalism values among third-grade students at MI Suren Gede Kertek. This research employed a quantitative approach using a quasi-experimental method with a Non-equivalent Control Group Design. The sample consisted of 61 students, divided into an experimental group and a control group. Data were collected through tests, questionnaires, and documentation and analyzed using validity, reliability, homogeneity, and Independent Sample t-Test analyses. The findings revealed that the average nationalism score of students in the experimental group was higher than that of the control group. The Independent Sample t-Test showed a significance value (2-tailed) of less than 0.001, indicating that H₀ was rejected and H₁ was accepted. These findings demonstrate that the integration of Wonosobo traditional sarong visual motifs as local wisdom-based learning media significantly influences the development of students’ nationalism values. Therefore, local wisdom-based learning media can serve as an effective alternative to foster nationalism while simultaneously introducing and preserving local cultural heritage among elementary school students.]]>
