Learning activities related to students' real-life experiences may create meaningful learning. Integrating traditional games into the physics classroom can reconstruct local knowledge into scientific knowledge. The use of technology can affect student learning achievement. One of the technologies currently attracting attention is Augmented reality (AR). This study investigates the impact of AR-integrated traditional games Nglarak Blarak on students' critical thinking and graphical representation skills. In this study, a quasi-experimental design was used, consisting of 62 10th junior high school students. Class A completed the "work and energy" concept of their physics learning using AR technology, while class B used PowerPoint and textbooks. Class A students had higher critical thinking and graphical representation skills scores than those in class B. In addition, it was found that the critical thinking and graphical representation skills of students in class A who used AR technology showed a significant correlation. The results of this study can be used as a reference for integrating technology and indigenous knowledge in physics learning.
