This paper discusses the effect of CPjBL models to improve students' thermodynamics learning outcomes. The methods of research was a quasi-experimnetal study and the sampel consisted of two classes. One class was assigned to be an experimental group (EG, n=29) and directed as  a collaborative project-based learning group. The other class was assigned to be the control group (CG, n=25) and directed as a conventional learning group. The study found that the use of CPjBL model in thermodynamic’s subject shown that students were more motivated to learn, more confident and more better solve problems given, responsible and able to work in teams. T-tests of learning outcomes for the experimental and control class were performed significantly difference. Finally, the conclusion of this research was CPjBL model more effective than conventional model in the thermodynamic's subject, especially in technical and  vocational education.
