This study aimed to determine PjBL-STEM implementations effect to improve science process skills and students’ learning outcomes on the material of substances and their characteristics. The type of research used was a quasі-experiment with a pre-test post-test control group design. The research subjects were students of class VII Darul Ihsan Islamic Junior High School Aceh Besar, which consisted of eight classes. The sample group was determined by purposive sampling technique so that two classes were obtained as the research sample, namely class VII-G as an experimental class and VII-H as a control class. The results showed that the implementation of the PjBL-STEM model could increase students’ science process skills. The average students’ science process skills in the control and experimental classes were 53 and 55 with sufficient categories. However, after implementing the Discovery Learning model in the control class and PjBL-STEM in the experimental class, the students' science process skills' average score increased to 76 with good categories and 86 with excellent categories. The PjBL-STEM model was also able to improve students’ learning outcomes. Based on the results of the t-test analysis with a significant score of 0.05, it showed that the post-test scores in both classes were obtained t-count (2.011) > t-table (1.666), so it was concluded that there was a significant difference between the two classes. N-gain testing showed an increase in students’ learning outcomes between the control and experimental classes with scores of 74 and 79. This study concluded that the PjBL-STEM model could improve science process skills and students’ learning outcomes.

Penemuan konsep materi pembelajaran secara mandiri dapat mempengaruhi kemampuan kognitif dan psikomotor peserta didik. Hasil observasi di SMAN 1 Karangtengah Demak menunjukkan bahwa pembelajaran masih berpusat pada guru sehingga kemampuan peserta didik dalam menemukan sendiri konsep materi masih kurang, hal ini menyebabkan rendahnya kemampuan kognitif dan psikomotor. Untuk menghindari hal tersebut diperlukan model pembelajaran yang sesuai yaitu inkuiri terbimbing. Guru belum menerapkan pembalajaran berbasis internet yang dapat membentuk sikap mandiri pada peserta didik, sehingga diperlukan pembelajaran berbasis internet seperti blended learning . Penelitian ini bertujuan untuk mengetahui pengaruh penerapan inkuiri terbimbing berbasis blended learning terhadap kemampuan kognitif dan psikomotor peserta didik kelas XI MIPA SMAN 1 Karangtengah Kabupaten Demak. Metode penelitian yang digunakan adalah eksperimen dengan pengambilan sampel menggunakan teknik cluster random sampling , diperoleh kelas XI MIPA 1 sebagai kelas eksperimen dan XI MIPA 4 sebagai kelas kontrol.
