Abstract

Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk menghasilkan bahan ajar kimia materi larutan buffer, hidrolisis, kelarutan dan hasil kali kelarutan berbasis project based learning yang valid, praktis, dan efektif. Model pengembangan yang digunakan adalah 4S TMD (Four Steps Teaching Material Development). Ada empat tahapan dalam model pengembangan 4STMD yakni tahap seleksi, strukturisasi, karakterisasi, dan reduksi didaktik. Kevalidan bahan ajar diuji oleh ahli materi, ahli pedagogik, dan ahli desain. Formula yang digunakan untuk menghitung data adalah V’Aiken. Kevalidan materi memiliki rata-rata sebesar 0,95 dengan kategori tinggi, Kevalidan pedagogik memiliki rata�rata sebesar 0,94 dengan kategori tinggi, dan kevalidan materi memiliki rata-rata sebesar 0,97 dengan kategori tinggi. Untuk melihat kepraktisan bahan ajar dilihat dari rata-rata angket kepraktisannya. Skor rata-rata kepraktisan sebesar 87 dengan kategori kepraktisan tinggi. Selanjutnya keefektifan bahan ajar ini dilihat dari hasil belajar yang dilakukan dengan cara memberikan soal pretest dan post-test. Berdasarkan nilai pretest dan post-test didapatkan nilai N-Gain sebesar 0,80 dengan keefektifan yang dalam kategori tinggi. Hal ini menunjukkan bahwa bahan ajar kimia telah memenuhi kriteria valid,praktis, dan efektif. Kata Kunci : Penelitian Pengembangan, Bahan ajar, Project Based Learning, Laurtan buffer, Hidrolisis, Kelarutan dan Hasil Kali Kelarutan ABSTRACT This research is a development research that aims to produce chemical teaching materials for buffer solutions, hydrolysis, solubility and solubility products based on project based learning that are valid, practical, and effective. The development model used is 4S TMD (Four Steps Teaching Material Development). There are four stages in the 4STMD development model, namely the stages of selection, structuring, characterization, and didactic reduction. The validity of teaching materials was tested by material experts, pedagogic experts, and design experts. The formula used to calculate the data is V'Aiken. Material validity has an average of 0,95 with a high category, pedagogic validity has an average of 0,94 with a high category, and material validity has an average of 0,97 with a high category. To see the practicality of the module, it can be seen from the average practicality questionnaire. The average practicality score is 87 with a high practicality category. Furthermore, the effectiveness of this teaching material is seen from the learning outcomes that are carried out by giving pretest and post�test questions. Based on the pretest and post-test values, the N-Gain value is obtained by 0,80 with effectiveness in the high category. This shows that the chemistry teaching materials meet the valid, practical, and effective criteria.
