Abstract

Peneliti bertujuan 1) Untuk mengetahui pengaruh pembelajaran kimia menggunakan laboratorium virtual terhadap hasil belajar siswa 2) Untuk mengetahui berapa besar peningkatan hasil belajar siswa melalui penggunaan laboratorium virtual. Jenis penelitian yang digunakan deskripsi kuantitatif. Populasi dalam penelitian ini seluruh siswa kelas XII MIPA SMA Muhammadiyah 4 Jakarta T.A 2020/2021. Sampel dalam penelitian ini terdiri dari 2 kelas dengan jumlah sampel 50 orang yang ditentukan dengan teknik sampling yaitu purposive sampling, yaitu XII MIPA 1 sebagai kelas eksperimen dengan model pembelajaran discover learning menggunakan laboratorium virtual berbasis eksperimen sebanyak 25 orang dan XII MIPA 3 sebagai kelas kontrol menggunakan model pembelajaran discover learning menggunakan demo sebanyak 25 orang. Instrumen penelitian berupa tes hasil belajar. Uji persyaratan telah dilakukan berupa Uji Parametrik ini di karenakan data yang diperoleh normal dan homogen. Pengujian hipotesis menggunakan paired sampel t test dengan signifikan 0,05 diperoleh hasil 0,00<0,05. Analisis data dan pengujian hipotesis dilakukan dengan bantuan SPSS 20.0 for windows. Berdasarkan hasil analisis diketahui bahwa penggunaan laboratorium virtual berpengaruh dalam peningkatan hasil belajar kimia siswa dengan nilai skor rata-rata gain sebesar 0,52. Kata kunci : hasil belajar, kimia, laboratorium virtual. / Researchers aim 1) To determine the effect of learning chemistry using a virtual laboratory on student learning outcomes 2) To find out how much increase in student learning outcomes through the use of a virtual laboratory. This type of research used quantitative description. The population in this study were all students of class XII MIPA SMA Muhammadiyah 4 Jakarta T.A 2020/2021. The sample in this study consisted of 2 classes with a sample of 50 people who were determined by a sampling technique, namely purposive sampling, namely XII MIPA 1 as an experimental class with a discover learning learning model using an experimental-based virtual laboratory as many as 25 people and XII MIPA 3 as a control class using learning model of discover learning using demo as many as 25 people. The research instrument was in the form of a learning outcome test. The requirements test has been carried out in the form of this Parametric Test because the data obtained are normal and homogeneous. Hypothesis testing using a paired sample t test with a significance of 0.05, the result is 0.00 <0.05. Data analysis and hypothesis testing were carried out with the help of SPSS 20.0 for windows. Based on the results of the analysis, it is known that the use of a virtual laboratory has an effect on improving student chemistry learning outcomes with an average gain score of 0.52. Keywords : chemistry, learning outcomes, virtual laboratory
