Students practical skills is one of scientific skills which must be mastered. Applying practical skills in the laboratory need an ability to scientific safety. This research was aimed to produce the students work sheet based on Laboratory Investigation-Scientific Safety that feasible and effective to improve the student's practical skills of Secondary School. This research and development (R & D) used Borg & Gall model with modification of eight steps; (1) preliminary study, (2) planning, (3) product development, (4) limited trial, (5) product revision, (6) field test, (7) product revision final product improvement) and, (8) limited dissemination. The data were collected by non-test techniques which included using product validation instrument, student questionnaire to response work sheet, practical skills observation sheet. Field trials were conducted using Pre-test-Post-test control group design with 35 subjects in the experimental and control classes. The data were analyzed using normality test, homogeneity test, and t test. The results were: (1) the students work sheet based on laboratory investigation scientific safety was considered good and proper by lecturer of media expert, material expert, science teacher, and colleague with mean value 89,5%, (2) the students practical skills improved to be 89.5 after using students work sheet. Practical skills improvement was evidenced by the acquisition of a t test significance value of 0.000 less than 0.05. Overall, it can be concluded that student's product based on laboratory investigation scientific safety focused theme of human digestive system was feasible to be used in learning and effective to improve students' practical skills of secondary school.

Penelitian ini termasuk penelitian eksperimen semu (Quasy Experiment) dengan desain penelitian pretest-posttest control group design. Pemilihan sampel menggunakan teknik simple random sampling dan menggunakan kelas, yaitu kelas VIII D sebagai kelas eksperimen dan kelas VIII F sebagai kelas kontrol. Kelas eksperimen diberikan perlakuan dengan menggunakan LKS IPA terpadu berbasis model connected dan kelas kontrol menggunakan LKS sekolah. Instrumen pengumpulan data adalah tes (pretest, posttest). Analisis data menggunakan uji Independent Sample T-test. Hasil penelitian menunjukkan bahwa: Rata-rata nilai posttest kelas eksperimen sebesar 78,17% dan kelas kontrol sebesar 71,77%. Berdasarkan hasil uji Independent Sample T-test p < 0...
