However, in the process of learning the student is less understanding the material provided by the teacher. One of the alternatives to solving the problem is by offering a PBI learning method. The purpose of this research is to know the improvement of student learning motivation after learning by using PBI learning method. This research was carried out on November 13-15, 2017. The design of this research uses a real experimental research design. The population in this study is all students of SMKN 1 Darul Kamal which amount to 198 students, while the sample in this research is 22 students of class X Electronics.
