Application of C4.5 Algorithm with Calculating Entropy-Based on Classification Method for Determining Prediction Graduate Students

The high level of competition in the education world make each individual or university continues to develop talent and ability competency. But the success rate of students is lowered, when students are not able to graduate on time. The time of student graduation becomes a benchmark for student and university success. Ways that can be done to answer these challenges is make data analysis using data mining techniques. University can do this prediction using data mining techniques. This research uses the C4.5 algorithm to construct a decision tree. Conducted a research of 115 active students in one of the state universities of Jakarta, the results of this research is, there were
