<![CDATA[This reseach was aimed to determine whether SiMaYang Tipe II learning model in improving metacognition abilities and concept mastery of electrolyte and non-electrolyte was better than problem solving learning model. The samples on this study were students of the 10th grade of MIA 1 as the 1st experiment class were applied to SiMaYang Type II model and the 10th grade of MIA 4 as the 2nd experiment class were applied to problem solving model at SMAN 1 Purbolinggo where they were got by using cluster random sampling. The results research indicates that SiMaYang Type II learning model to improve metacognition abilities and concept mastery was better than use problem solving learning model. Penelitian ini bertujuan untuk mengetahui apakah model pembelajaran SiMaYang Tipe II dalam meningkatkan kemampuan metakognisi dan penguasaan konsep lebih baik dibandingkan dengan model pembelajaran problem solving pada materi larutan elektrolit dan non-elektrolit. Sampel dalam penelitian ini adalah kelas X MIA 1 sebagai kelas eksperimen I yang diterapkan model SiMaYang Tipe II dan X MIA4sebagai kelas eksperimen II yang diterapkan model problem solving di SMAN 1 Purbolinggo dengan teknik cluster random sampling. Hasil Penelitian menunjukan bahwa model pembelajaran SiMaYang Tipe II dalam meningkatkan kemampuan metakognisi dan penguasaan konsep lebih baik dibandingkan dengan model pembelajaran problem solving. Kata kunci: metakognisi, problem solving, SiMaYang Tipe II]]>
