Abstract. A research on the use of PBL learning model aided module on material buffer solution which aims to determine (1) the improvement of learning outcomes, (2) adherence to learning activities that teachers do, (3) the student activity and (4) the students' responses to learning. The study design was a classroom action research (PTK) with two cycles. Each cycle consists of planning, action, observation and evaluation, as well as analysis and reflection. The subjects were students of class XI SMA Negeri 1 Banjarmasin MIA with 36 students. Data were collected through observation, achievement test and questionnaire.
