Judul: Analisis CHAID untuk Identifikasi Ketepatan Waktu Lulus Berdasarkan Karakteristik Mahasiswa
Abstrak: Bogor Agricultural University (IPB) Under-graduated program is one of the best university in Indonesia which also produces the best graduates. From the data of IPB graduated students in 2010-2013 it shows that the percentage of student who graduates on time is 30.94%. It indicates that there are still many students who do not graduate on time. This study aims to look at the characteristics affecting accuracy of graduation on IPB students using CHAID (Chi-squared Automatic Interaction Detection) analysis. The analysis on IPB students CHAID able to classifies students ontime with the highest classification probability the characteristics derived from FEM, have a GPA of more than 3.39 and taking a minor during college at IPB, while the lowest classification probability that clasifies IPB students who graduate on time have the characteristics derived from FAPERTA-FAHUTAN, with GPA of less than or equal to 2.87 and from jabodetabek. The analysis on IPB FMIPA CHAID unable to classifies students on time. More over the classification accuracy value for IPB students is 74.6% and for IPB FMIPA students is 80%.

Judul: Analisis CART Ketepatan Waktu Lulus Berdasarkan Karakteristik Mahasiswa di FEM dan FAPERTA
Abstrak: Graduate on time is one of the indicators of a student’s success in obtaining their undergraduate degrees. Previous study using CHAID (Chi-Squared Automatic Interaction Detection) method concluded that the highest probability classification for the IPB students who graduated on time comes from FEM and the lowest probability classification comes from FAPERTA. According to that, the purpose of this research is to identify the student’s characteristics as an indicator of the timeliness pass from the faculty with highest and lowest number of students who graduated on time using CART method. Tree classification of FEM classifies the characteristics of the highest students that graduated on time by 75% as the students from Departements of IE and MAN. Tree classification of FAPERTA classifies the characteristics of the highest students that graduated on time by 26.1% as the students from Departements of AGH and PTN and have GPA greater than 3.335. The classification tree of FAPERTA is better to estimate students who graduated on time with accuracy value 81.47% and the classification tree of FEM is better to estimate students who didn’t graduate on time with accuracy value 71.4%.
