<![CDATA[Low active student engagement in textile experimentation and decoration development learning at vocational high schools remains a challenge in implementing the Merdeka Curriculum. This study aimed to describe the implementation of the Problem-Based Learning (PBL) model and student learning outcomes in appliqué embroidery among Phase F students in the Fashion Design and Production Department (DPB) of SMKN 1 Baureno. A quantitative pre-experimental one-shot case study design was employed. The participants were 21 students of class XI DPB 2, selected through purposive sampling. Data were collected using a PBL syntax implementation observation sheet, a 10-item multiple-choice cognitive test, and a psychomotor product assessment rubric. Data were analysed descriptively using percentages and mastery categories. The results showed that PBL implementation was observed at an average of 83.6%, categorized as very good. Nineteen of 21 students (90.48%) achieved the mastery criterion of ?75, while 2 students (9.52%) did not. Because the design did not include a pretest or comparison group, the findings are interpreted as descriptive and associational rather than as evidence of a causal effect. The results indicate that PBL can be implemented with high fidelity in this vocational context and that most students met the specified mastery criterion, while also highlighting the need for remedial scaffolding for students with limited foundational embroidery and fine-motor skills.]]>
