<![CDATA[Abstract. A research on the use of the learning model SiMaYang on material solubility and solubility product (Ksp) at SMA Negeri 9 Banjarmasin. This study aims to determine (1) the activities of teachers, (2) the activity of students, (3) improving student learning outcomes, and (4) the students' responses. The study design was a classroom action research (PTK) with two cycles. Each cycle consists of planning, implementation, observation and reflection.
