Abstract
This research development aims were to create and determine validity and practicality categories of buffer solution module based on guided inquiry equipped with HOTS type problems. This research was a Research and Development with Plomp development model. Instrument used was module validity and practicality questionnaire. Module was validated by 5 validators. Practicality was determined by providing a questionnaire to 2 chemistry teachers and 51 students of class XII MIPA SMAN 8 Padang. The data obtained were analysed with the Kappa Cohen formula. The result of the research obtained average kappa moment value validity (0,90), average kappa moment value practicality of teacher response (0,93) and the practicality of student response (0,84). This result showed that the module which has been developed was very valid and practical to used in learning
Highlights
Penelitian pengembangan ini bertujuan untuk menghasilkan serta menentukan kategori validitas dan praktikalitas modul larutan penyangga berbasis inkuiri terbimbing dilengkapi soal-soal tipe Higher Order Thinking Skills (HOTS)

Summary
Kimia merupakan ilmu yang mempelajari komposisi dan struktur zat kimia serta hubungan keduanya dengan sifat zat tersebut[1]. Pengembangan bahan ajar berbasis inkuiri terbimbing pada materi larutan penyangga sebelumnya telah dilakukan oleh Ifelicia (2017). Bahan ajar yang dihasilkan belum dilengkapi dengan soal-soal tipe HOTS (Higher Order Thinking Skills) baik pada lembar kerja maupun pada lembar evaluasi. Bahan ajar pada materi larutan penyangga yang digunakan oleh guru di sekolah tersebut belum dilengkapi soal-soal tipe HOTS baik pada lembar kerja maupun pada lembar evaluasinya, sehingga belum mampu melatih kemampuan berpikir tingkat tinggi siswa. Penyajian bahan ajar dengan soal-soal tipe HOTS dapat membantu siswa untuk memperoleh pemahaman konseptual secara mendalam dan melatih kemampuan berpikir tingkat tinggi siswa untuk memecahkan permasalahan yang baru dalam situasi berbeda[10]. Pada penelitian ini dilakukan pengembangan modul larutan penyangga berbasis inkuiri terbimbing dilengkapi soal-soal tipe HOTS serta menentukan kategori validitas dan praktikalitas terhadap modul yang telah dikembangkan
