Salah satu faktor yang menentukan kualitas perguruan tinggi adalah persentasi kemampuan mahasiswa untuk menyelesaikan studi tepat waktu. Saat ini, masalah kegagalan studi siswa dan faktor - faktor penyebabnya menjadi topik yang menarik untuk diteliti. Perguruan tinggi perlu mendeteksi perilaku mahasiswa yang memiliki status “tidak diinginkan” tersebut sehingga dapat diketahui faktor - faktor penyebab kegagalannya. Berdasarkan uraian di atas, diperlukan analisa terhadap data-data mahasiswa sepeti Jenis Kelamin, Umur, Agama, Tempat tinggal, IPS, Disiplin, dan Hutang, berdasarkan data mahasiswa yang dimiliki sebanyak 97 data sehingga bisa dimanfaatkan dalam pengolahan data mining. Di mana data mining digunakan untuk menggali dan mendapatkan informasi dari data dengan jumlah besar. Salah satu metode data mining adalah pengklasifikasian data. Dengan menggunakan Metode Klasifikasi dengan konsep Algoritma Decision tree C4.5 menghasilkan accuracy sebesar 90.00%, hasil dari precision adalah 87.50, dan hasil dari recall sebesar 100%. Diharapkan dapat meningkatkan keinginan Lembaga Universitas atau Perguruan tinggi untuk memberikan pikiran yang baik, pandangan, dan  kebijakan  baru kepada mahasiswa yang memiliki permasalahan dalam perkuliahan, dengan kata lain memaksimalkan mahasiswa dalam upaya peningkatan persentase minat kuliah mahasiswa.

One way to enhance the likelihood that more students will graduate within the specific major that they begin with is to attract the type of students who have typically (historically) done well in that field of study. This chapter details a study that utilizes data mining techniques to analyze the characteristics of students who enroll as actuarial students and then either drop out of the major or graduate as actuarial students. Several predictive models including logistic regression, neural networks and decision trees are obtained. The models are then compared and the best fitting model is determined. The regression model turns out to be the best predictor. Since this is a very well understood method, it can easily be explained. The decision tree, although its underpinnings are somewhat difficult to explain, gives a clear and well understood output. Not only is the resulting model a good one for predicting success in the major, it also allows us the ability to better counsel students.

Private Universities (PTS) compete so tight in providing performance in producing quality graduates. In addition, the number of universities in Indonesia which counts a lot both PTN and PTS makes the higher competition between universities as well. So the university strives to improve quality and provide the best education for service recipients, namely students, where one of the problems if there are some students who are late graduating or not on time so that it becomes an obstacle to the progress of the college. Prediction of students graduating on time is needed by university management in determining preventive policies related to early prevention of Drop Out (DO) cases. This prediction aims to determine the academic factors that influence the period of study and build the best prediction model with Data Mining techniques. There are 11 attributes used for Data Mining Classification, namely NPM, Gender, Age, Department, Class, Occupation, Semester 1 Achievement Index, Semester 2 Achievement Index, Semester 3 Achievement Index, Semester 4 Achievement Index and Information as result attributes. From the results of evaluations and validations that have been carried out using the RapidMiner tools the accuracy of the Decision Tree (C4.5) method is 98.04% in the 3rd test. The accuracy of the Naïve Bayes Method is 96.00% in the 4th test. And the accuracy of the K-Nearest Neighbor Method (K-NN) of 90.00% in the second test.
