<![CDATA[The era of the Industrial Revolution 5.0 requires the education sector to adapt to rapid technological developments, particularly through the adoption of innovative learning models. This study aims to develop a feasible, practical, and effective comic-based interactive Problem-Based Learning (PBL) model to improve elementary school students' critical thinking skills. The method used is research and development (R&D) with the ADDIE model, involving a qualitative approach to assess the product's feasibility and practicality, and a quantitative approach to measure its effectiveness through a pretest-posttest design. The research subjects were 30 fifth-grade students at Elementary School 9 Sila, Bima Regency. The instruments used included a feasibility questionnaire, a practicality questionnaire, and a critical thinking skills test. The results showed that the products developed for the PBL model (90.8%), interactive comics (96.5%), and critical thinking skills tests (95.7%) were feasible for use. The practicality level of interactive comics (93.25%) and critical thinking skills tests (97.75%) was very practical for use in elementary school learning. The n-Gain test results showed an increase in critical thinking skills with an average score of 0.74 (high category). This was supported by a significant paired-samples t-test (p < 0.05), which showed a difference between the students' pretest and posttest scores. In general, these results indicate that the application of the comic interactive-based PBL model is effective in improving students' critical thinking skills.]]>
