<![CDATA[Abstract This study was conducted to improve the critical and creative thinking skills of seventh-grade junior high school students through the use of an e-comic integrated with the Problem Based Learning (PBL) model. The study employed the Research and Development (R&D) method using the ASSURE model, which consists of the following stages: Analyze Learner Characteristics, State Objectives, Select Methods, Media, and Materials, Utilize Materials, Require Learner Participation, and Evaluate and Revise. This study is categorized as development research. The participants consisted of 20 seventh-grade students at SMP Negeri 1 Glenmore. Data were collected using expert validation sheets to assess the validity of the developed media, student responsse questionnaires, teacher observation sheets on learning implementation, and student activity observation sheets to measure practicality, as well as assessment instruments to evaluate students' critical and creative thinking skills. The data were analyzed using quantitative and qualitative descriptive analysis. The validity, practicality, and effectiveness of the developed media were analyzed descriptively, while improvements in students' critical and creative thinking skills were analyzed using the paired sample t-test and the normalized gain (N-Gain) test. The findings indicate that the developed PBL-based e-comic learning media met the criteria of being valid, practical, and effective. Expert validation results demonstrated that the media achieved a very high level of validity, while students' responsses and teachers' evaluations of the learning implementation indicated positive results. Furthermore, the developed learning media effectively enhanced students' higher-order thinking skills. Keywords: E-Comic, Problem Based Learning (PBL), Critical Thinking, Creative Thinking. Abstrak Penelitian ini dilakukan untuk meningkatkan kemampuan berpikir kritis dan kreatif peserta didik di SMP kelas VII melalui penggunaan e-komik yang dipadukan dengan model Problem Based Learning (PBL). Penelitian ini menggunakan metode Research and Development (R&D) dengan model ASSURE yang meliputi tahap analisis karakter peserta didik, menentukan tujuan pembelajaran, pemilihan metode, media, dan bahan ajar, pemanfaatan media, teknologi, dan bahan ajar, melibatkan partisipasi peserta didik, evaluasi dan revisi. Penelitian ini adalah penelitian pengembangan (development research). Partisipan penelitian terdiri dari 20 peserta didik kelas VII di SMP Negeri 1 Glenmore. Teknik pengumpulan data dilakukan melalui lembar validasi oleh para ahli untuk mengukur kevalidan, angket responss peserta didik, lembar observasi guru mengelola pembelajaran, dan lembar observasi kegiatan peserta didik untuk mengukur kepraktisan, serta instrumen penilaian untuk mengukur kemampuan berpikir kritis dan kreatif peserta didik. Teknik analisis data yang digunakan meliputi analisis deskriptif kuantitatif dan kualitatif. Data kevalidan, kepraktisan, dan keefektifan dianalisis menggunakan analisis deskriptif, sedangkan peningkatan kemampuan berpikir kritis dan berpikir kreatif dianalisis menggunakan uji paired sample t-test dan N-Gain. Hasil penelitian menunjukkan bahwa media pembelajaran e-komik berbasis PBL yang dikembangkan telah memenuhi kriteria valid, praktis, dan efektif. Validasi para ahli menunjukkan hasil yang sangat baik, sedangkan respons peserta didik dan penilaian pelaksanaan oleh guru menunjukkan hasil yang positif. Selain itu, penggunaan media yang dikembangkan dapat meningkatkan kemampuan berpikir tingkat tinggi. Kata Kunci: E-Komik, Problem Based Learning (PBL), Berpikir Kritis, Berpikir Kreatif. ]]>
