Process skills are skills that used to find, grow and develop the fact, concept, attitude and values required by work or scientific method. With practiced of science process skills is expected to solve the problems that exist in society which suitable with objectives of curriculum 2013. Learning model that can be used to practice student’s process skills is problem based learning (PBL). Where the problem solving skills, student will learn two things, those are student find the answer to the problem and they knew how the process or how to solve the problem. The aims of this study (1) to describe the feasibility of learning, (2) describe the student learning outcomes, (3) describe the results of students 'process skills and (4) describe the students' response to the process skills that have been learned trough Problem Based Learning (PBL) model on garbage theme. The type of this research was Pre Experimental Design using One Shot Case Study. The sample used in this study were students of class VII-C, amounting to 34 students. The analyze does it with quantitative descriptive. The results showed that the feasibility study of the first meeting, the second meeting and the third meeting was 3.4 included in the excellent category. The results of study were 32 students completed the classical completeness was 94% (very good). The result of process skills as many as 22 students with excellent information dan classical completeness of 97% (excellent). Students' response to science learning process by using Problem Based Learning (PBL) model on garbage theme to practice student’s process skill was 87% (very good).
