This study aimed to investigate the effectiveness of the Problem-Oriented Project-Based Learning (POPBL) model in teaching manufacturing product design in vocational higher education at Makassar ATI Polytechnic. The research involved 15 students for a limited trial and 35 students for an extended trial. The study used questionnaires, pre-test and post-test cognitive tests, and parametric statistical tests to evaluate the effectiveness of the POPBL model. The results showed that the POPBL model was effective, with an average very agree response of 80% in the limited trial and 92% in the extended trial. The average posttest scores were 64.80 and 78.97 in the limited and extended trials, respectively, which were significantly higher than the pretest scores. The parametric statistical test using the t-test also showed that the POPBL model was effective in both the limited and extended trials. Based on these results, it can be concluded that the POPBL model is an effective approach to teaching manufacturing product design in vocational higher education.
