The research results show that the N-gain is 0.84 with an increase in learning outcomes of 29.3%, this is because students can understand the material directly through project activities. In the interest in entrepreneurship which was tested through a questionnaire instrument, it was found that there had been an increase in the high category from 10.2% to 84.6% because through the integrated PjBL Model the CEP approach in the material studied was linked directly to entrepreneurial products, so that students became active and felt happy participating in activities. learning.
