The results of the analysis were aspect 3) was 35.29%, aspect 4) was 23.54%, aspect 5) was 11.76%, aspect 6) was 11.76%, and aspect 8) was 17.65%. Based on the analysis, it can be concluded that X grade students’ science processing skills in Senior High School “Y” Ponorogo regency have not been optimally used and in the low category.
