Keterampilan berpikir kritis merupakan kompetensi utama yang perlu dimiliki siswa untuk menghadapi tantangan abad ke-21, namun hasil PISA 2018 dan 2022 serta hasil ANBK di MTs Yusuf Annur menunjukkan bahwa kemampuan tersebut masih tergolong rendah. Salah satu cara yang dapat dilakukan untuk mengatasi hal tersebut adalah dengan menggunakan media pembelajaran yang inovatif, interaktif, dan kontekstual. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan media Sc-SEBION (Syzygium cumini–Explosion Box Interactive Online Version) berbasis PjBL yang terintegrasi dengan kearifan lokal tanaman juwet (Syzygium cumini L.) Desa Lopang pada materi perubahan lingkungan untuk meningkatkan keterampilan berpikir kritis siswa, serta mendeskripsikan validitas, kepraktisan, dan efektivitasnya. Jenis penelitian yang digunakan adalah Research and Development (R&D) dengan menggunakan model pengembangan 4D. Uji validitas isi modul ajar, media, dan instrumen penilaian kognitif (pretest-pretest) dilakukan oleh tiga dosen dan satu guru IPA menggunakan lembar validasi. Instrumen penilaian kognitif juga diuji validitas empiris menggunakan Pearson Total Correlation dan reliabilitas menggunakan Cronbach's Alpha. Uji kepraktisan dilakukan menggunakan angket System Usability Scale (SUS) dengan responden kelas VII B (23 siswa) dan observasi keterlaksanaan pembelajaran yang dilakukan oleh 2 observer. Uji efektivitas diperoleh melalui pengerjaan pretest-posttest oleh responden, yang hasil akhirnya dilakukan perhitungan ketuntasan belajar, paired sample T-test serta N-Gain. Hasil penelitian menunjukkan bahwa validitas isi modul ajar 93.67%, media 93.15%, dan instrumen penilaian kognitif 93.63%, seluruhnya berkategori sangat valid. Instrumen penilaian kognitif juga valid secara empiris (r hitung 0.606 - 0.927)  dan sangat reliabel (pretest 0.936 dan posttest 0.934). Kepraktisan media melalui uji SUS memperoleh skor rata-rata 76.63 dengan kategori Good, grade B, dan tingkat penerimaan Acceptable, sedangkan hasil keterlaksanaan pembelajaran mencapai 90.21%. Jika ditinjau dari keefektifannya, sebanyak 78.26% siswa mencapai ketuntasan belajar setelah pembelajaran, serta terdapat perbedaan yang signifikan antara pretest dan posttest (sig<0,001). N-Gain juga menunjukkan rata-rata sebesar 0.68 (kategori sedang), dengan peningkatan tertinggi pada indikator inference sebesar 0.85 (kategori tinggi). Berdasarkan hasil tersebut, media Sc-SEBION dinyatakan valid, praktis, dan efektif untuk meningkatkan keterampilan berpikir kritis siswa pada materi perubahan lingkungan.

CRITICAL THINKING SKILLS

Critical thinking is widely recognized as an essential competency for students in the twenty-first century. Nevertheless, the results of the 2018 and 2022 PISA, as well as the Indonesia's Computer-Based National Assessment (ANBK) conducted at MTs Yusuf Annur, indicate that students' critical thinking skills remain unsatisfactory. One promising approach to addressing this issue is the use of innovative, interactive, and contextual learning media. Accordingly, this study aimed to develop Sc-SEBION, a PjBL media that integrates the local wisdom of the Java plum (Syzygium cumini L.) from Lopang Village in Environmental Exchange Topic for enhancing students' critical thinking skills. The study also described its validity, practicality, and effectiveness. This study employed a Research and Development (R&D) design based on the 4D model. Content validity of the teaching module, instructional media, and cognitive assessment instruments (pretest and posttest) was evaluated by three lecturers and one science teacher. The cognitive assessment instruments were further tested for empirical validity using the Pearson Total correlation test and for reliability using Cronbach's alpha. Practicality was evaluated using the System Usability Scale (SUS) completed by 23 VIIB-grade students and supported by classroom implementation observations conducted by two observers. Effectiveness was determined through learning mastery, paired-samples T-test, and N-gain analysis based on pretest and posttest scores. The teaching module, Sc-SEBION, and the cognitive assessment instruments obtained content validity scores of 93.67%, 93.15%, and 93.63%, respectively, indicating a high level of validity. The cognitive assessment instruments were also empirically valid (r = 0.606–0.927) and highly reliable (Cronbach's alpha = 0.936 for the pretest and 0.934 for the posttest). The mean score of SUS is 76.63, corresponding to a Good rating, Grade B, and an Acceptable level of usability, while classroom implementation reached 90.21%. Following the intervention, 78.26% of the students achieved learning mastery, and the difference between the pretest and posttest scores was statistically significant (p<0.001). In addition, the average N-gain score was 0.68, indicating a moderate improvement in critical thinking skills, with the highest score in inference indicator (0.85 in high category). These findings demonstrate that Sc-SEBION is a valid, practical, and effective instructional media for enhancing students' critical thinking skills on the environmental change topic.
