Abstract

Tujuan dari penelitian ini adalah untuk (1) mengetahui apakah terdapat peningkatan hasil belajar kimia siswa yang signifikan melalui penerapan model pembelajaran Snowball Throwing(2) untuk mengetahui seberapa besar peningkatan hasil belajar kimia siswa SMA melalui penerapan model pembelajaran Snowball Throwing. Penelitian ini dilakukan di SMA Santa Maria Della Strada kelas XI MIPA. Populasi penelitian ini adalah seluruh siswa kelas XI MIPA SMA Santa Maria Della Strada.yang terdiri dari satu kelas dengan jumlah sampel 30 orang. Adapun instrumen yang digunakan dalam pengambilan data adalah instrumen tes hasil belajar kimia yang berupa 14 butir soal pretest dan posttest dalam bentuk pilihan ganda. Dari hasil penelitian diperoleh nilai rata-rata pretes dan posttest pada kelas eksperimen, dimana peneliti mengasumsikan bahwa nilai pretest memiliki skor rata-rata sebesar 43,77, sedangkan untuk nilai posttest memiliki skor tara-rata sebesar 85,30. Berdasarkan nalisis yang dilakukan antara lain: uji prasyarat analisis (Uji Normalitas) dan uji Hipotesis (untuk melihat adakah peningkatan signifikan atau tidak). Berdasarkan uji prasyarat analisis yaitu uji normalitas menggunakan Shapiro-Wilk menunjukan nilai pretest dengan sig>0,05 yakni 0,06 artinya data terdistribusi normal. Selanjutnya Uji Hipotesis yang dilakukan menggunakan Paired Sampel T-tes yang diperoleh nilai t hitung sebesar 19.37 > t tabel 2,05 sehingga dengan demikian Ha diterima dengan arti bahwa terdapat peningkatan hasil belajar kimia siswa SMA pada materi hidrokarbon melalui model pembelajaran Snowball Throwing. Kata Kunci: Hasil Belajar; Model Pembelajaran;Snowball Throwing; Peningkatan; Hidrokarbon. / The aims of this study were (1) to find out whether there was a significant increase in students' chemistry learning outcomes through the application of the Snowball Throwing learning model (2) to find out how much the high school students' chemistry learning outcomes increased through the application of the Snowball Throwing learning model. This research was conducted at SMA Santa Maria Della Strada class XI MIPA. The population of this study were all students of class XI MIPA SMA Santa Maria Della Strada, which consisted of one class with a total sample of 30 people. The instrument used in data collection was the chemistry learning outcomes test instrument in the form of 14 pretest and posttest items in the form of multiple choices. From the results of the study, the average pretest and posttest values were obtained in the experimental class, where researchers assumed that the pretest score had an average score of 43.77, while the posttest score had an average score of 85.30. Based on the analysis carried out, among others: analysis prerequisite test (Normality Test) and Hypothesis test (to see whether there is a significant increase or not). Based on the prerequisite analysis test, namely the normality test using the Shapiro-Wilk, it shows a pretest value with sig> 0.05, namely 0.06, meaning that the data is normally distributed. Furthermore, the Hypothesis Test was carried out using the Paired Sample T-test which obtained a t value of 19.37 > t table 2.05 so that Ha was accepted in the sense that there was an increase in high school students' chemistry learning outcomes in hydrocarbon material through the Snowball Throwing learning model.
