Implementasi Model Pembelajaran Pjbl Terintegrasi Stem Pada Alat Pembakaran Sampah Tanpa Asap Materi Suhu, Kalor, Dan Pemuaian Untuk Meningkatkan Hasil Belajar Kognitif Siswa Kelas VII SMPN 1 Tapung Hulu
The research aims to determine the cognitive abilities of class VII students through the application of the STEM-based PjBL model using a smokeless waste burner and to determine the differences in the cognitive abilities of classes that use the PjBL-STEM model and conventional learning. This research was carried out at SMPN 1 Tapung Hulu, Kampar Regency, Riau Province. The type of research used is Quasi Experimental Design with the Posttest Only Non-Equivalent Control Group Design method. The population of this study was 176 class VII phase D students. The sample in this study consisted of 59 students, with class VII D totaling 29 students as the experimental class and class VII A totaling 30 students as the control class. Data collection instruments were in the form of a cognitive ability posttest consisting of 15 multiple choice questions. The data analysis technique used is descriptive analysis through the average value of student learning outcomes and inferential analysis through normality tests, homogeneity tests and hypothesis tests. The results of the descriptive analysis can be concluded that using the PjBL-STEM model on smokeless waste burners is better than the control class. The results of the inferential analysis of Hypothesis Testing in this study using an independent T-test resulted in significant differences between students' cognitive abilities. Therefore, the STEM-based PjBL model using smokeless waste burning media can be used as an alternative that can be applied in the science learning process at school to improve students' cognitive learning outcomes.
