This study aims to describe the effect of implementing the Problem-Based Learning (PBL) model assisted by Kahoot, integrated with local wisdom, on the learning interest of elementary school students. The research employed a quantitative approach with a quasi-experimental design conducted at SD Negeri 11 Saparan, involving 14 sixth-grade students. The learning procedure included problem orientation based on local culture, organizing students for learning, investigation, presentation of results, and evaluation through Kahoot quizzes. Based on the descriptive analysis, the average score of participants increased from 59.14 to 65.29. All participants showed an increase in scores, with an average improvement of 6.14 points. This indicates that the treatment had a positive impact on students' learning interest. Technical constraints such as internet connectivity issues were addressed through group work. Thus, the use of Kahoot in the PBL model is effective in increasing students' learning interest. Learning interest is a psychological factor that greatly determines the success of the learning process, especially at the elementary school level. However, initial observations in various schools indicate that low student learning interest is often caused by monotonous, less contextual instruction that is not connected to students' daily lives. To address this problem, innovations in learning models are needed that are not only student-centered but also capable of integrating technology and local cultural values. The PBL model offers a structure based on authentic problems, while Kahoot, as an interactive quiz platform, can enhance student engagement. Furthermore, integrating local wisdom into problem scenarios is believed to make learning more meaningful as it is closely related to students' daily experiences.
