Survei PISA 2024 menunjukkan bahwa siswa Indonesia memliki kemampuan berpikir kreatif yang rendah. Penelitian ini bertujuan untuk mengembangkan alat pengusir lalat berbasis STEM (Science, Technology, Engineering, and Mathematics) dalam bentuk Lembar Kerja Siswa (LKS) untuk meningkatkan keterampilan berpikir kreatif siswa. Metode penelitian menggunakan pendekatan kualitatif dengan model Research and Development (R&D) tipe ADDIE (Analysis, Design, Development, Implementation, and Evaluation). Subjek penelitian adalah 24 siswa kelas X di SMA Negeri 4 Langsa. Instrumen yang digunakan meliputi lembar validasi, tes kemampuan berpikir kreatif, observasi, serta angket respons siswa dan guru. Hasil validasi oleh ahli materi dan media menunjukkan bahwa LKS yang dikembangkan sangat layak digunakan dengan nilai validasi rata-rata 91,11%. Respons siswa terhadap LKS juga sangat positif dengan persentase rata-rata 92%. Berdasarkan hasil pretest dan posttest, terjadi peningkatan signifikan pada keterampilan berpikir kreatif siswa. Nilai rata-rata pretest adalah 48,6, sedangkan nilai rata-rata posttest meningkat menjadi 85,2, dengan N-Gain sebesar 0,71 yang termasuk kategori tinggi. Indikator keterampilan berpikir kreatif yang mengalami peningkatan tertinggi adalah elaboration (94%), diikuti oleh originality, flexibility, dan fluency. Dengan demikian, pengembangan LKS alat pengusir lalat berbasis STEM terbukti efektif dalam meningkatkan keterampilan berpikir kreatif siswa dan dapat diterapkan sebagai media pembelajaran inovatif di sekolah.

The PISA 2024 survey showed that Indonesian students have low creative thinking skills. This study aims to develop a STEM (Science, Technology, Engineering, and Mathematics)-based fly repellent in the form of Student Worksheets (LKS) to improve students' creative thinking skills. The research method used a qualitative approach with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) Research and Development (R&D) model. The research subjects were 24 10th-grade students at SMA Negeri 4 Langsa. The instruments used included validation sheets, creative thinking ability tests, observations, and student and teacher response questionnaires. Validation results by material and media experts showed that the developed LKS was very suitable for use with an average validation score of 91.11%. Student responses to the LKS were also very positive with an average percentage of 92%. Based on the pretest and posttest results, there was a significant increase in students' creative thinking skills. The average pretest score was 48.6, while the average posttest score increased to 85.2, with an N-Gain of 0.71, which is considered high. The creative thinking skill indicator that experienced the highest increase was elaboration (94%), followed by originality, flexibility, and fluency. Thus, the development of STEM-based fly repellent worksheets has proven effective in improving students' creative thinking skills and can be implemented as an innovative learning medium in schools.
