Alin Oktavia (ID 409332017) 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.

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
