Abstract


Abstract This study aims to develop a sublimation tool to improve problem solving skills and performance in the laboratory. The research method used is the Research and Development (R and D) method with a 4D model. The research sample consisted of control and experimental classes. The sampling technique used was purposive sampling. The results showed that the developed sublimation tool stated: (1) effective for use, it was obtained (1.64). In addition, the results of the development are also good in improving students' problem solving skills with n-gain (0.64) with high criteria (2) the results of responses from students' responses to the attractiveness aspect (100 percent), readability aspect (96.29 percent), and tool design (100 percent). Based on the results of research and development, it can be stated that the developed sublimation tool is effective for improving problem solving skills and performance in the laboratory and can be used in practical experiments in studying the material for separating mixtures with sublimation techniques.

 

Keywords: development, sublimation, problem solving.

Sampel penelitian terdiri dari kelas kontrol dan eksperimen. Teknik pengambilan sampel menggunakan purposive sampling. Hasil penelitian menunjukkan bahwa alat sublimasi hasil pengembangan    dinyatakan: (1) efektif untuk digunakan didapatkan sebesar (1,64). Selain itu, hasil pengembangan juga baik dalam meningkatkan keterampilan pemecahan masalah siswa dengan n-gain (0,64) dengan kriteria tinggi (2) hasil tanggapan dari respon siswa pada aspek kemenarikan  (100 persen), aspek keterbacaan (96,29 persen), dan desain alat (100 persen). Berdasarkan hasil penelitian dan pengembangan, dapat dinyatakan alat sublimasi hasil pengembangan efektif untuk meningkatkan keterampilan pemecahan masalah dan kinerja di laboratorium serta dapat digunakan pada percobaan praktikum dalam mempelajari materi pemisahan campuran dengan teknik sublimasi.

 

Kata kunci: pengembangan, sublimasi, pemecahan masalah.
