<![CDATA[This research is motivated by the importance of strengthening local wisdom-based character amidst the challenges of globalization that have resulted in the decline of politeness values and cultural identity of students. This study aims to analyze the role of the cultural Thursday habits integrated into social studies learning on the formation of local wisdom character of eighth-grade students at SMP Negeri 9 Semarang. The study used a mixed methods approach with a sequential explanatory design and a pre-experimental one-group pretest–posttest design. The research sample consisted of 40 students selected using proportional stratified random sampling. Data were collected through questionnaires, observations, interviews, and documentation. Quantitative analysis was conducted using the Wilcoxon Signed Rank Test, while qualitative data were analyzed thematically. The results showed a significant increase in students' local wisdom character, indicated by a significance value of 0.000 (<0.05). Qualitatively, character formation occurs through consistent habituation through the use of cultural attributes, Javanese language habits, and performing arts activities. The integration of the program into social studies learning creates contextual and holistic learning, encompassing cognitive, affective, and psychomotor aspects. Thus, the cultural Thursday habits has proven effective in forming students' character based on local wisdom.
