Didimus Armindo Neonbasu, 2026: The Effect of Implementing the Project Based Learning (PjBL) Model on Students’ Learning Outcomes in Computer Systems in Grade X Culinary Classes at SMK Negeri 3 Kupang. Informatics Education Study Program, Faculty of Teacher Training and Education, Citra Bangsa University, Kupang. Supervisor I: Jhon Enstein, S.Kom., M.Cs., and Supervisor II: Diana Y. A. Fallo, S.Kom., M.T. This study aims to determine the effect of implementing the Project Based Learning (PjBL) model on students’ learning outcomes in Computer Systems in Grade X Culinary classes at SMK Negeri 3 Kupang. This research employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The sample consisted of 50 students, comprising 25 students from Grade X Culinary 1 as the experimental group and 25 students from Grade X Culinary 2 as the control group. Data were collected through tests (pretest and posttest), observations, questionnaires, and documentation. The data were analyzed using descriptive statistics, normality tests, homogeneity tests, and an Independent Samples t-test. The results showed that the experimental group’s mean pretest score was 67.80, increasing to 75.80 on the posttest. Meanwhile, the control group’s mean score increased from 58.60 to 61.60. The hypothesis test yielded a significance value of 0.013, which was lower than 0.05; therefore, H₀ was rejected and Hₐ was accepted. Thus, the implementation of the Project Based Learning (PjBL) model has an effect on students’ learning outcomes in Computer Systems in Grade X Culinary classes at SMK Negeri 3 Kupang.
