The main visual component of this project is the Sido Mukti batik motif, which will be used to design characters in Sentai's Martial Mayhem video game. This motif was chosen for its deep philosophical meaning and its ability to preserve regional culture through digital media. Research and Development (R&D) was the process employed, encompassing problem identification, data collection, graphic design, character implementation into a Unity-based game, and testing using black-box and System Usability Scale (SUS) approaches. Based on the test results, 14 out of 15 scenarios ran as planned, with an accuracy rate of 93.75%. The average SUS score was 68.25, or ‘sufficiently adequate,’ given by 20 respondents. Both technically and visually, the batik-themed Gold Ranger character was successfully integrated into the game. Based on these results, the addition of regional cultural elements to digital games enhances their visual appeal and serves as a useful educational tool for cultural preservation. As a result, this study significantly promotes the development of games that emphasise regional cultural values.
