Description This research aims to determine the effect of virtual laboratory on student laboratory skills on acid-base titration in SMAN 26 Jakarta. The subject of this study was XI IPA 1 as control group and XI IPA 3 as experiment group and was conducted on February through March 2019. The method that used in this research is quasi experiment with posttest only control group design. The sample was chosen by purposive sampling technique. The experiment group uses virtual laboratory in practical activities, while the control group uses assistance in practical activities. The result showed that the average score of the posttest in experiment group was 80.77 while the control group is 67.04. Meanwhile, the result of t-test shows that tobtined was 6,625 > ttable was 1,67. It means there is a difference on student’s laboratory skills between the experiment group and control group. Therefore, it can be conclude that the virtual laboratory in practical activities has a positive effect on student’s laboratory skills on acid base titration.

Penelitian ini bertujuan untuk mengetahui pengaruh positif laboratorium virtual terhadap keterampilan laboratorium siswa pada materi titrasi asam basa di SMA Negeri 26 Jakarta. Penelitian ini dilakukan di kelas XI IPA 1 (kelas kontrol) dan XI IPA 3 (kelas eksperimen), dilaksanakan pada semester genap. Metode penelitian yang digunakan adalah quasi eksperimen dengan Posttest Only Control Group Design. Teknik sampling yang digunakan pada penelitian ini adalah Purposive Sampling. Penelitian ini terdiri atas kelas eksperimen dan kelas kontrol, masing-masing berjumlah 36 siswa. Kelas eksperimen menggunakan laboratorium virtual dalam kegiatan praktikum, sedangkan kelas kontrol menerapkan asistensi dalam kegiatan praktikum. Hasil penelitian menunjukkan rata-rata nilai posttest kelas eksperimen sebesar 80,53 dan kelas kontrol sebesar 67,14. Hasil pengujian terhadap hipotesis diperoleh dengan nilai thitung sebesar 5,821 > ttabel sebesar 1,67 dengan nilai taraf signifikan 0,05, hal tersebut menunjukkan bahwa terdapat pengaruh positif laboratorium virtual dalam kegiatan praktikum terhadap terhadap keterampilan laboratorium siswa pada materi titrasi asam basa.
