Education before 2045 should build the character of Indonesia’s Golden Generation to have a nationalist and cultured spirit. However, this program has not been implemented well. As happened in learning materials that support the formation of nationalist character such as local language, culture, and Pancasila values, which now have not been optimally understood by elementary school students because the learning methods are too monotonous. The solution to this problem is inventing Pekara Japa method (Dhelikan Game Integrated with Javanese Culture and Pancasila). This method collaborate dhelikan game with local language, culture, and Pancasila. This research uses literature and field studies involving elementary school students as respondents. This research aims to create a superior generation with nationalist character. The research shows that Pekara Japa helps students in applying Krama language (the most polite form of Javanese) and Pancasila values, also to understand Javanese culture. So the conclusion is that Pekara Japa is an appropriate learning method for the success of character education to support the realization of Golden Indonesia 2045.
