This study aims to produce a valid and practical ethnoscience-based chemical module by raising salt farmers' habits. This study refers to the 4D model from Tiahgrajan, S. Semmel & Semmel, which was modified into three stages: defining, designing, and developing. Chemistry modules are tested for validity and practicality before it is used in chemistry learning. Validation was carried out by three experts and adjusted to the scoring table, while the practicality test used a student response questionnaire using a Likert scale. The result showed that the ethnoscience-based chemistry module was in the feasible and practical category used in learning to acquire scores, respectively, at a rate of 0.91 and 3.00. Penelitian ini bertujuan untuk menghasilkan modul kimia berbasis etnosains yang valid dan praktis dengan mengangkat kebiasaan petani garam. Penelitian ini mengacu pada model 4D dari Tiahgrajan, S. Semmel & Semmel yang dimodifikasi menjadi tiga tahap yaitu define, design, dan develop. Modul kimia dilakukan ujicoba kevalidan dan kepraktisan sebelum digunkaan dalam pembelajaran kimia. Validasi dilakukan oleh tiga tim ahli dan disesuaikan dengan tabel penskoran, sedangkan uji kepraktisan menggunakan angket respon peserta didik dengan menggunakan skla likert. Hasil penelitian menunjukkan bahwa modul kimia berbasis etnosains dalam kategori layak dan praktis digunakan dalam pembelajaran dengan perolehan skor berturut-turut sebesar 0.91 dan 3.00.

Actually, chemistry learning is very fun, but it takes a high motivation, passion and confident. Based on that, the teacher's effort in developing student's learning activity is very important, because the students' learning activity becomes the determinant of the success of learning that is done. The use of an appropriate learning methods was an alternative to overcome the problem of low absorption of students to the lesson. The arm of this research was to know how the applying of cooperative learning model Teams Games Tournament (TGT) was type through domino card media to affected the learning chemistry achievement of XI-MIA student in MAN 4 Aceh Besar. Instruments used i.e. research instruments and data instruments. Data collection techniques are observation, test results, and questionnaires. Based on the objectives and the results of data analysis in this study, shown that the teacher activity in managing learning for each cycle was in very good category. Student activity at the time of applying the cooperative learning model Teams Games Tournament (TGT) type through domino card media on petroleum material was active. Students' learning achievement after the implementation of Cycle I, cycle II and final test respectively was about 61.29%, 90.32% and 93.55%. Student response to the application of cooperative learning model type Teams Games Tournament (TGT) through domino card media on petroleum material was positive.
