Abstract This study aimed at designing and implementing the model of project-based learning integrated with Ethno-STEM. The learning model is an approach to Science in Technology, Engineering, and Mathematics in the context of Ethnoscience. The learning model was applied to the learning of organic chemistry for secondary metabolite topics to develop students’ entrepreneurial character. The subjects of this study were chemistry students who attended the organic chemistry and entrepreneurship course. The study took place in the Chemistry Department of UNNES. The research instruments included tests, observation sheets, and non-tests to measure the entrepreneurial characters. The data were analyzed using the qualitative descriptions and practicality tests of the model of project-based learning integrated with Ethno-STEM. In this study, the increase in the students’ entrepreneurial characters was measured based on the N-gain score. The results of this study and discussion found (1) the character description of the model of project-based learning integrated with Ethno-STEM to develop the students’ entrepreneurial characters, (2) the model was able to improve the students’ entrepreneurial characters based on the N-gain scores, (3) the students were able to produce creative products and design chemical batik motifs with secondary metabolite structures on canvas and chemical bottles. The students responded positively to the developed model of project-based learning integrated with Ethno-STEM.
