This study aims to analyze the problem solving skills of students of class XI MIA at SMAN 1 Tomini. The measurement of problem solving ability is seen from the ability of students to solve problems using steps adapted from problem solving steps according to Polya, namely understanding the problem, planning the solution, implementing the settlement plan and checking again.The sample of this research is 20 people, the sampling is determined by technique random sampling. Problem solving ability data were obtained from students by giving a test of 8 validated essay questions. The results of this study indicate that the average ability of class XI MIA students at SMAN 1 Tomini in acid-base material obtained an average percentage of each stage of problem solving, namely the stages of understanding the problem and implementing plans, including the high category with each percentage of 88. 69% and 77.08%, at the stage of planning the settlement, it is included in the moderate category with a percentage of 67.18% and at the stage of re-examining, it is included in the low category with a percentage of 52.81%. So it can be concluded that the ability achieved by class XI MIA students at SMAN 1 Tomini on acid-base material is in the high category with a percentage of 71.44%.
