Materi hukum-hukum dasar kimia yang diajarkan dijenjang SMA selama ini masih belum optimal sesuai tuntutan kurikulum. Hal ini dapat dilihat berdasarkan hasil ujian nasional masih rendah. Nilai ujian nasional materi hukum-hukum dasar kimia tahun 2018 dan 2019 secara berturut 16,6 dan 35,2. Penelitian ini bertujuan: (1) Mendeskripsikan kelayakan LKPD berbasis TTW yang dikembangkan pada materi hukum-hukum dasar kimia, (2) Mendeskripsikan tanggapan peserta didik terhadap LKPD berbasis TTW yang dikembangkan pada materi hukum-hukum dasar kimia, (3) Mendeskripsikan tanggapan pendidik terhadap LKPD berbasis TTW yang dikembangkan pada materi hukum-hukum dasar kimia. Metode penelitian ini menggunakan R&D dengan model 4-D yaitu define, design, develop, dan disseminate. Subjek penelitian ini adalah peserta didik kelas X IPA 1 berjumlah 25 orang. Instrumen penelitian yaitu lembar penilaian validitas LKPD oleh para ahli, lembar angket tanggapan peserta didik dan pendidik. Hasil penelitian menunjukkan bahwa LKPD memperoleh nilai sangat baik. Penilaian kelayakan memperoleh 93,3%. Tanggapan peserta didik dan pendidik masing-masing memperoleh 86% dan 94,8% dengan kategori sangat baik. Berdasarkan hasil penelitian dapat disimpulkan bahwa LKPD berbasis think talk write pada materi hukum-hukum dasar kimia layak digunakan sebagai bahan ajar.

The material for the basic laws of chemistry taught at the senior high school level has so far not been optimal according to the demands of the curriculum. This can be seen based on the results of the national exam which are still low. The scores for the national exams on basic laws of chemistry in 2018 and 2019 were 16,6 and 35,2 respectively. This aims of this study: (1) Describe the feasibility of the TTW-based LKPD developed on the basic laws of chemistry, (2) Describe student responses to the TTW-based LKPD which was developed on the material of basic chemical laws, (3) Describe the educator responses to the TTW-based worksheets developed on the basic laws of chemistry. This research method uses R&D with a 4-D model, namely define, design, develop, and disseminate. The subject of this research were 25 class X IPA 1 students. The research instruments were LKPD validity assessment sheets by experts, student and educator response questionnaire sheets. The results of the study show that the LKPD scores very well. The feasibility assessment obtained 93,3%. The responses of students and educator respectively obtained 86% and 94,8% in the very good category. Based on the results of the study, it can be concluded that the worksheets based on think talk write on the material laws of basic chemistry are appropriate to be used as teaching materials.
