Abstract


Telah dilakukan penelitian yang bertujuan untuk mengetahui kelayakan bahan ajar pada materi pokok Kesetimbangan Kimia SMA yang diujicobakan secara terbatas di SMA Negeri 2 Lamongan. Rancangan penelitian mengikuti model pengembangan Thiagarajan (model 4D) tanpa melakukan tahap penyebaran (disseminate). Rancangan Bahan ajar ditelaah oleh dua dosen kimia dari Universitas Negeri Surabaya, satu guru kimia SMA Negeri 2 Lamongan, dan divalidasi oleh 3 dosen kimia Universitas Negeri Surabaya dan 3 orang guru kimia SMA Negeri 2 Lamongan. Hasil penelitian menunjukkan bahwa bahan ajar yang dikembangkan layak digunakan sebagai salah satu sumber belajar. Penilaian dosen kimia terhadap bahan ajar sangat layak dengan persentase rata-rata jawaban terhadap aspek materi secara umum sebesar 85,42%, aspek kesesuaian materi dengan level makroskopik dan sub-mikroskopik sebesar 81,25%, aspek penyajian sebesar 87,5%, dan aspek bahasa sebesar 80%. Penilaian guru kimia terhadap bahan ajar sangat layak dengan persentase rata-rata jawaban terhadap aspek materi secara umum sebesar 83,34%, aspek kesesuaian materi dengan level makroskopik dan sub-mikroskopik sebesar 83,33%, aspek penyajian sebesar 85,83%, dan aspek bahasa sebesar 83,33%. Respon siswa terhadap bahan ajar sangat layak dengan persentase rata-rata jawaban terhadap aspek materi secara umum sebesar 95,56%, aspek kesesuaian materi dengan level makroskopik dan sub-mikroskopik sebesar 98.09%, aspek penyajian sebesar 93,33%, dan aspek bahasa sebesar 80%.

This study had been conducted to know the feasibility of teaching material topic of Chemical Equilibrium of senior high school. The teaching material has been tested to the limited group in SMA Negeri 2 Lamongan. Design of this research based on Thiagarajan development model (4D model) without the disseminate stage. This teaching material was analyzed by 2 chemistry lecturer of Surabaya State University, 1 chemistry teacher of SMA Negeri 2 Lamongan, and was validated by 3 chemistry lectures of Surabaya State University and 3 chemistry teachers of  SMA Negeri 2 Lamongan. The result of research show teaching material which is developed is feasible to be used as learning resources. Lectures evaluation about teaching material is very good with average percentage answer for matter aspect in general is 85,42%, for suitability with macroscopic an sub-microscopic aspect is 81,25%, presentation aspect is 87,5%, and language aspect is 80%. Teacher evaluation about teaching material is very good with average percentage answer for matter aspect in general is 83,34%, for suitability with macroscopic an sub-microscopic aspect is 83,33%, presentation aspect is 85,83%, and language aspect is 83,33%. Students response for teaching material is very good with average percentage answer for matter aspect in general is 95,56%, for suitability with macroscopic an sub-microscopic aspect is 98,09%, presentation aspect is 93,33%, and language aspect is 80%.

Keywords: Development of teaching material, Macroscopic and Sub-Microscopic Approach, Chemical Equilibrium
