<![CDATA[Database learning in vocational education requires learning environments that can connect theoretical knowledge with practical project activities and coding practice. However, existing learning practices at SMKN 4 Bojonegoro remain predominantly teacher-centered and provide limited integration between project-based learning, digital learning materials, and database coding practice. This study aims to develop and evaluate NexaDB, a Moodle-based Learning M, anagement System that integrates Project-Based Learning (PjBL) and the Code Runner plugin to support students' cognitive and psychomotor database competencies. The study employed a Research and Development approach using the ADDIE model and a quantitative quasi-experimental non-equivalent control group design with pretest and posttest. The participants were 72 Grade XI Software Engineering students at SMKN 4 Bojonegoro, consisting of an experimental group using NexaDB with PjBL and a control group receiving the existing teacher-centered instruction. The results showed higher N-Gain scores in both cognitive and psychomotor competencies in the experimental group than in the control group. The independent-samples t-test indicated significant differences between the groups in cognitive competency (t=12.70, p<.001) and psychomotor competency (t=7.364, p<.001). The effect sizes (Cohen's d) and 95% confidence intervals further indicated the magnitude and precision of the intervention effect. The novelty of this study lies in integrating Moodle, Code Runner, and PjBL into a single learning environment that connects database concepts, coding practice, project development, assessment, and feedback. The findings contribute theoretically to the integration of project-based and technology-supported learning in vocational database education and provide a practical learning platform for teachers and students.]]>
