Authentic learning includes the necessary foundation in learning physics. However, the limitations of the physics module based on authentic learning have an impact on the common problem-solving skills of students. Therefore, the purpose of this study is to analyze the effectiveness of a static fluid module with authentic learning to practice student problem-solving skills. This research is research and development using the 4-D model (Define, Design, Develop, Disseminate). Class trials using

... group pre-test and post-test design. The subjects of the research trial were 33 students of class XB SMA in Banjarmasin. The data were obtained through tests of problem-solving skills. The results showed that the module was effective because the results of Mann Whitney test were sig. = 0.00; means there is a significant increase in problem-solving skills. Also, the students' problem-solving skills were in the very good category. Thus, a static fluid module with authentic learning is effective for practicing student problem-solving skills.
