DEVELOPMENT OF CHEMISTRY WORKSHEET WITH PROBLEM SOLVING ORIENTATION IN STOICHIOMETRY MATTER OF X GRADE SEMESTER 1

Tujuan penelitian ini adalah untuk mengetahui kelayakan Chemistry Worksheet berorientasi Problem  Solving pada materi stoikiometri kelas X semester 1. Kelayakan Chemistry Worksheet dianalisis oleh guru kimia dan dosen kimia pada kriteria konstruksi, isi, dan kebahasaan. Desain penelitian yang digunakan adalah model 4-D (define, design, develop, dan disseminate) menurut Thiagarajan, namun tahap disseminate tidak dilakukan. Telaah Chemistry Worksheet dilakukan oleh dosen kimia dan guru kimia SMA, untuk menelaah konstruksi, isi, dan kebahasaan Chemistry Worksheet yang dikembangkan. Uji coba terbatas dilakukan oleh 15 siswa di SMA Negeri 1 Magetan. Metode pengumpulan data yang digunakan adalah metode angket dan tes. Teknik analisis data dilakukan secara analisis deskriptif kuantitatif dan kualitatif. Data hasil analisis penelitian ini menunjukkan bahwa Chemistry Worksheet berorientasi Problem Solving telah memenuhi kriteria kelayakan konstruksi,isi, dan kebahasaan dengan persentase berturut-turut 82,17%, 85,88%, dan 75%, sehingga Chemistry Worksheet ini layak untuk digunakan sebagai media pembelajaran. Kata Kunci: Problem Solving, stoikiometri, Chemistry Worksheet  The aim of this research was known the feasibility of Chemistry Worksheet with Problem  Solving orientation on stoichiometry matter in X grade semester I. Feasibility of Chemistry Worksheet was analyzed by Chemistry teacher and Chemistry lecturer on construction, content, and language criteria.. Research design used 4-D model (define, design, develop, and disseminate) but disseminate phase was not done. Chemistry Worksheet review was conducted by chemistry lecturer and chemistry high school teacher, to review construction, content, and language of Chemistry Worksheet developed. Limited trial was done by 15 students in SMA Negeri 1 Magetan Collecting data method used were questionnaire and test method. Data analysis technique were done by quantitative and qualitative descriptive analysis. The data analysis result of this research showed that Chemistry Worksheet with Problem  Solving orientation had filled feasibility criteria on construction, contents, and language with percentage respectively 82,17%, 85,88%, and 75%, so this Chemistry Worksheet is feasible to be used as learning media.
