<![CDATA[This research aims to describe how efforts are made to increase learning motivation through the application of problem based learning for Class IX students at SMP Negeri 2 Pemulutan Selatan. This type of research is Classroom Action Research (PTK) which consists of 2 cycles. The subjects in this classroom action research (PTK) were students of Class IX of SMP Negeri 2 Pemulutan Selatan with the number of students being 20 people.
