ABSTRACT
This thesis is explained about the feasibility test of computer based
learning media (virtual lab) on teaching solubility and solubility product. This
research aimed to know the perception of student and the feasibility of the learning
media; that built by Macromedia Flash Pro 8; the feasibility is shown by the student’s

achievement from the pre-test and post test data. The population of this research is
students of second year in Methodist 1 Senior High School Medan. The samples were
two classes which selected by random sampling method. The experiment class is
taught by learning media (virtual lab) while the control class is taught by
conventional method. The research instrument is the questioner for the student’s
perception and the achievement test for the feasibility media, the research instrument
is standardized by the expert valuator and empiric validity. Data is analyzed by two
kind of analysis program they were Microsoft Excel for Windows 2003 and SPSS.
The result of the achievement test is 10 valid items and the reliability value is 1.04.
The learning media is built to know the students perception of the media
and students achievement in learning solubility and solubility product, the student
answered the question before the teaching treatment (pre test) and after teaching
treatment (post test), while the questioner answered by the students to know the
perception and data will used to know the feasibility of media. The research result
shown that the data are normal distribution and sample is homogenous. The student
perception is shown that the media is enough feasts in every category, the scale of
result data is 70.44-82.70%. For students achievement data we got the media is valid
and reliable and the reliability value from alpha value is 1.105. The last one is the
hypothesis test by independent sample t-test the value is 0.144 it is bigger than
significant value 0.05 so the hypothesis is accepted. It can be concluded that the

computer based learning media is feasible to use on teaching solubility and solubility
product.

CHAPTER V
CONCLUSION AND SUGGESTION

1.1.Conclusion
1. The perception of students towards computer-based learning media (virtual
lab) on the subject of the solubility and solubility product is good, and show
that the media is feasible.
2. The computer-based learning media (virtual lab) is feasible to use on study
solubility and solubility product.
3. The student achievement taught by using computer-based learning media
(virtual lab) is significant higher than conventional method on solubility and
solubility product

1.2.Suggestion
1. For chemistry teacher should using the computer-based learning media (virtual
lab) in teaching solubility and solubility product topic. It will be able to
increase the students achievement and attract the students to study and trained
them to think critically to seek and find the concept of the material.
2. For school holder in order to provide and increase the facility of school
especially computer laboratory and equipment and material for doing
experiment in the laboratory.
3. For the next researcher and chemistry teacher that built the computer-based
learning media (virtual lab) should prepared and arrange the media better.
4. It is very expected that there is another researcher to built a good learning
media as more effective computer-based learning media (virtual lab).
