The purpose of this study was to determine the impact of the implementation of Project Based Learning (PjBL) on learning activities in the Electrical Automation Installation lecture material. Based on the research assessment, it appears that many passive, daydreaming students are busy with cellphones and unrelated activities during the learning process. This research is an experimental study with a class action research model consisting of two cycles. Each cycle consists of two meetings. Data was collected using observation to see changes in learning activities and tests used to measure student learning outcomes. Based on observations, the average learning activities of the first and second cycles were 66.7% and 86.3%. Student learning outcomes also increase classically. In the first cycle, 59.25% or 16 students had reached the minimum mastery criteria, and in the second cycle, 92.6% or 25 students had reached the minimum mastery criteria. This means that the application of Project Based Learning can improve student activities and learning outcomes in learning Electric Automation Installation.
