This study aims to determine the improvement Skills Process of Science after developing science-learning media about human waste-based digestive systems. The research was conducted at SDN Kapuk 02. This research used R & D research method which refers to Dick and Carey model. Respondents in this study consisted of expert test (media, language, and material), one to one, testtrial small group, andtest fieldtest. The results of the development of Torso Digestive System Human assessed by media experts ie 88.3%, material experts 90%, and linguists 93.3%. The next stage of Human Digestive System Media performedtrial one to one with 89% product feasibility, trial small group with 90.1% product feasibility, and field test with 90.4% feasibility. Assessment made into the category is very good. PPP in this research was conducted by classroom teachers. Classroom teachers conduct assessments before and after media use. At the time before using the Human Digestive System media, the student's KPS earned an average of 68.7%, after using Human digestive System media has increased to 89.5%. This indicates that the Human digestive system media improves student's KPS until it reaches the completeness criteria. Thus the media of Human Digestive System has effectiveness to the student's KPS.
