Kreativitas perlu dimiliki oleh siswa SMK, khususnya dalam menghadapi berbagai tantangan di dunia kerja. Oleh karena itu, perlu dikembangkan e-Modul Project Based Learning berintegrasi STEM yang mampu meningkatkan kreativitas siswa SMK. Penelitian ini bertujuan untuk mendeskripsikan efektivitas e-modul Project Based Learning berintegrasi STEM terhadap kreativitas siswa dalam materi fisika suhu dan kalor. Penelitian dilaksanakan di kelas X Multimedia 1 SMKN Wonoasri, dengan sampel penelitian yang digunakan sebanyak 20 orang siswa yang dipilih secara random. Instrumen yang digunakan adalah tes hasil belajar yang berjumlah 5 buah soal essay. Data dianalisis menggunakan uji N-gain. Indikator kreativitas adalah berpikir lancar, berpikir luwes, elaborasi, dan berpikir orisinil. Dari analisis data, diperoleh hasil kemampuan berpikir lancar siswa memperoleh nilai n-gain sebesar 0,11, berpikir luwes n-gain sebesar 0,49, elaborasi memperoleh n-gain sebesar 0,21 dan berpikir orsinil memperoleh n-gain 0,44. Dengan demikian, disimpulkan bahwa bahwa efektivitas e-modul Project Based Learning berintegrasi STEM berkategori sedang. Creativity needs to be owned by vocational students, especially in facing various challenges in the world of work. Therefore, STEM integrated Project Based Learning E-Module needs to be developed that can improve the creativity of vocational students. This study aims to describe the effectiveness of the STEM integrated Project Based Learning e-module on student creativity in temperature and heat physics material. The study was conducted in Multimedia X class 1 Wonoasri Vocational School, with a sample of 20 students selected randomly. The instrument used was a learning achievement test which consisted of 5 essay questions. Data were analyzed using the N-gain test. Indicators of creativity are fluent thinking, flexible thinking, elaboration and original thinking. From the data analysis, the result of students' ability to think smoothly obtained an n-gain value of 0.11, flexible thinking of n-gain of 0.49, elaboration obtained n-gain of 0.21 and original thinking obtained n-gain of 0.44. Thus, it was concluded that the effectiveness of the Project Based Learning e-module integrated with STEM was of medium category.
