The current state of national character in Indonesia is deeply concerning. Society, including students, is increasingly influenced by teachings that contradict the values of Pancasila, leading to a decline in nationalism. Key issues among students include indifference towards their peers' difficulties, lack of discipline in studying, and a preference for foreign cultures over their own. The personal competence of teachers is crucial in addressing these issues. Teachers who exemplify positive attitudes related to nationalism can effectively foster a sense of nationalism in their students. This is because teachers not only impart knowledge but also serve as role models through their attitudes, words, and actions. The purpose of this study is to describe the profile of teacher personal competence and its implications for the development of nationalism values among students in the SKI (Islamic Cultural History) subject at MTs.

The data analysis technique used is content analysis, with data validation performed through triangulation.
