Computer Based Test (CBT) is an application that is used in the
operation of computer-based test. One of the advantages of CBT applications
that can present a question and answer choices were randomized to avoid
possible fraud committed by the examinee. This study tested a random function
of CBT applications based on Java and MySQL database server with the object of
comparison is the function of a random function random MySQL and Java Class
Library.
Variables used in this study is the access time and a combination of
questions and question the same answer choices. Testing is done by way of
modeling facilities that display the page question and answer choices to
determine the access time of the emergence of the question and the resulting
combination. The results of the calculations was tested by examining the average
similarity to know the difference.
After testing, it is known that there is a difference in access time
question using MySQL random function with the function of random Java Class
Library. Average access time with the question of random functions for MySQL
41650473.6250 nanosecond is longer than the average access time with the
question of random functions for Java Class Library 35905823.7431 nanosecond.
But the combination of questions and answer choices are similar to the question
by MySQL random function of 63.6% is smaller than the random use of Java Class
Library function that reaches a percentage of 65.1%.
