Abstract

The purpose of this study was to develop and tested the feasibility of virtual
chemistry laboratory (VCL) as practical media in class XI SMA. This study also
aimed to analyze student achievement, student understanding of submicroscopic
level and student activity in learning using VCL on topic solubility and solubility
product. The samples to test the feasibility of media were two expert validators
and five chemistry teachers. This research was conducted in State Senior High
School 1 Binjai. Samples of this research were64 students that was divided into
two classes, experiment class and control class. Experiment class was learned by
using virtual chemistry laboratory while control class was learned without using
virtual chemistry laboratory. The instruments were questionnaire to analyze the
feasibility of VCL media, objective tests (multiple choice) to analyze student
achievement, worksheet (essay test) to measure understanding of students in
submicroscopic level and observation sheet to observe students activity.
Normality test of student achievement in control class and experiment class were
0.057 and 0.642 respectively, while student understanding of submicroscopic level
in control class and experiment class were 0.104 and 0.126 respectively, it means
the data were normally distributed. Homogeneity test of student achievement and
student understanding in submicroscopic level were 0.083 and 0.446 respectively,
it means the samples were homogeneous. The result obtained (1) virtual
chemistry laboratory media that developed is suitable with eligibility standard of
BSNP (National Education Standards Board) (2) student achievement that was
learned by using virtual chemistry laboratory media is higher than learned without
using virtual chemistry laboratory media (3) students understanding of
submicroscopic level that was learned by using virtual chemistry laboratory media
is higher than learned without using virtual chemistry laboratory media (4) student
activity that was learned by using virtual chemistry laboratory media is more
active than learned without using virtual chemistry laboratory media (5) student
activity has positive correlation with student achievement r = 0.518 and
coefficient determinant 26.9% (6) student activity has positive correlation with
student understanding of submicroscopic level r = 0.505 and coefficient
determinant 25.5
