Policies regarding key performance indicators of State Universities continue to be encouraged to implement problem-based and collaborative learning. Therefore, innovation in learning is needed with learning methods that empower the role of students (student-centered learning), one of which is case-based (closed case study). In line with the Vision and Mission of the Faculty of Mathematics and Natural Sciences, The State University of Surabaya for the 2021-2025 period, one indicator is the implementation of research-based education characterized by edupreneurship. The purpose of this research is to improve the understanding and edupreneurship of undergraduate chemistry education students. Treatment to achieve this goal is case study-based learning (closed case study) assisted by student activity sheets (SAS) on analytical chemistry. The research sample was 20 undergraduate Chemistry Education students from the 2023 batch of the Faculty of Mathematics and Natural Sciences, Unesa. The research followed a quasi-experimental one-group pretest-posttest design. The variables in this study were evaluated using an assessment instrument for student understanding of analytical chemistry, questionnaire responses to closed cased study learning, and the edupreneurship attitude variables used are (1) self efficacy, (2) tenacity, (3) courage in making decisions, (4) creativity, and (5) independence.. Data on changes in conceptual understanding were then explained descriptively as an introduction and reinforced using inferential analysis using the Wilcoxon Signed Ranks Test because the population was known to be non-normally distributed (0.006 < 0.05). The results showed a significant change in students' understanding of analytical chemistry (basic chemical separation concepts) before and after learning (Asymp. Sig. (2-tailed) value 0.00< 0.05). This achievement is in line with the results of the respondent questionnaire, which showed that more than 80% stated that learning based on closed case studies and edupreneurship can increase understanding and edupreneurship attitude on the variable self-efficacy, courage in making decisions and independence.
