This study aims to develop learning interest in algebraic arithmetic operations by leveraging digital developments through the application of Quiziz ETNO, a Problem-Based Learning (PBL) model integrated with Batak culture. Using a quasi-experimental method with a pretest and posttest design, the research subjects were students of grades VIII-1 as the experimental class and VIII-2 as the control class from SMP Negeri 1 Meranti. The results showed that the use of Quiziz ETNO increased student interest in algebraic arithmetic operations, increasing student enthusiasm by 8% in participating in the learning process, and demonstrating significant improvements in learning outcomes. In conclusion, this study demonstrates that the use of technology in learning can improve student interest and learning outcomes. Keywords: Interest. Algebraic Arithmetic Operations, Quiziz
