Penelitian ini bertujuan untuk melihat perubahan belajar materi sistem periodik unsur menggunakan TGT (Team Games Tournament) berbantukan alat peraga terhadap hasil belajar Di Kelas X SMA UISU Medan. Penelitian ini dilaksanakan di SMAS UISU Medan dan dilaksanakan pada Agustus 2019 s/d September 2019. Populasi pada penelitian ini adalah seluruh siswa kelas X SMA UISU Medan Tahun Pelajaran 2018/2019 yang terdiri dari kelas IPA dan IPS sedangkan sampel yang digunakan adalah pada kelas IPA yang berjumlah 33 siswa. Metode penelitian yang digunakan dalam penelitian ini adalah Quasi Experimental. Analisis data dilakukan dengan menggunakan Microsoft Excel. Berdasarkan analisis data, hasil penelitian ini menunjukkan bahwa thitung sebesar 4,54 dan ttabel sebesar 1,669 pada taraf signifikan 5% atau α = 0,05. Karena thitung ttabel (4,54 1,669), maka hipotesis alternatif penelitian (Ha) diterima yang berarti bahwa Ha : Terdapat pengaruh TGT (Team Games Tournament) dengan menggunakan alat peraga terhadap materi sistem periodik unsur. Maka Kesimpulan dalam penelitian ini adalah Pembelajaran Materi Sistem Periodik Unsur Berhasil Menggunakan TGT (Team Games Tournament) Berbantukan Alat Peraga Terhadap Hasil Belajar Di Kelas X SMA UISU Medan.Kata kunci: Quasi Experiment, TGT (Team Games Tournament)

The demands on chemistry learning require hands-on action in the form of practicums to fit understanding of chemical concepts, examine the theories obtained and relate them to everyday scientific phenomena through scientific activities in the laboratory. So that cognitive, affective, and psychomotor learning outcomes are achieved. This research is a type of qualitative descriptive research. This study investigates student perceptions and Self-Regulated Learning (SRL) on integrated blended learning Project Based Learning that affects student learning outcomes. The research subjects were nine people students who were enrolled in basic chemistry courses. This research was conducted for seven meetings where the learning process was carried out with a mixture of online and offline lectures called Blended Learning. Data collection was conducted through interviews to determine student perceptions of Blended Learning and a questionnaire to determine the student's SRL level. Learning Outcomes (LO) tests were in the form of cognitive, affective, and psychomotor. The interview data were analyzed inductively. Meanwhile, the SRL data analysis and the LO test are presented as an integrated and comparative description. Students' interviews revealed positive perceptions about the learning. This study found that the students' SRL were in the high (56%), medium (33%), and low (11%) categories. The LO assessment was obtained from the pre-test and post-test; all students' scores increased. As for the attitude, the measurements showed four categories: very good (67%), good (11%), adequate (11%), and poor (11%). Assessment of instruments designed showed that 67% of the instruments were developed while another 33% were underdeveloped.
