DESAIN & UJI COBA INTEGRASI KETERAMPILAN PROSES SAINS DALAM PENGEMBANGAN E-LKPD PEMBUATAN SABUN PADA MATERI KOLOID
KPS (science process skills) as an approach to learning is very important because it fosters experiences other than the learning process, and to support this approach, appropriate teaching materials are needed as learning resources. This study discussed about the integration of science process skills (KPS) in the development of E-LKPD on colloid material soap maked. This study aimed to 1) determine the integration of KPS in the development of E-LKPD soap maked on colloid material; 2) knowing the validity of the E-LKPD integrated by KPS on soap maked on colloid material; 3) knowing the practicality of the E-LKPD integrated KPS in soap maked on colloid material. This research was a development research with the stages of Analysis, Design, Development and Implementation. Data collection at SMA Santa Maria Tanjungpinang with 1 chemistry teacher and 20 students. The result of this research was that the E-LKPD integrated KPS which was produced for the manufacture of colloid material soap in the form of an android application. This E-LKPD met the very valid criteria with the results of the material expert's test of 84.3%, while the results of the media expert's test were 93.75%. The percentage of practicality of educators towards E-LKPD was 89% in the very practical category, while 83% of students were in the practical category.
