Judul: Identifikasi Karakteristik Lulusan Kelompok Program Studi Magister IPB Berdasarkan Keberhasilan Studi Mahasiswa
Abstrak: Graduate School of Bogor Agricultural University (IPB-SPs) has been established since 1975 started by seven Masters program. In the mean time, the IPB Graduate School had grown to 67 study programs. The success of student in each program could be assesed by their grade point average (GPA) and the study duration. Based on those characteristics, the author figure out that the 61 study programs could be grouped into four clusters. Cluster 1 includes study program which has the best academic characteristic among the clusters. It has highest level of GPA and shortest duration of study. This achievement might be induced by the background characteristic of the students. The member of this cluster associated to young students from high reputation university. Meanwhile, Cluster 2 is cluster which has the mean value of GPA around its mean value and also has a longer duration of study. The member of this cluster are the students whose characterictics are poor. It happened because the background characteristic of bachelor students are not correlated with the Masters program and their GPA are below standard.

Judul: Analisis keberhasilan studi mahasiswa program magister sekolah pascasarjana ipb
Abstrak: Status penerimaan mahasiswa magister institut pertanian bogor (ipb) dibagi menjadi dua, yaitu status percobaan dan status biasa. Hasil studi mahasiswa magister dievaluasi berdasarkan status penerimaan tersebut. Penelitian ini bertujuan mendeskripsikan karakteristik mahasiswa magister, menganalisis faktor-faktor yang mempengaruhi keberhasilan mahasiswa magister tahap evaluasi, dan mengkaji faktor-faktor yang mempengaruhi keberhasilan lulusan mahasiswa magister berdasarkan ipk dan masa studi. Analisis deskriptif digunakan untuk mendapatkan gambaran umum karakteristik mahasiswa magister berdasarkan status penerimaan mahasiswa, sedangkan faktor-faktor yang mempengaruhi keberhasilan mahasiswa baik tahap evaluasi maupun kelulusan dianalisis menggunakan analisis cart (classification and regression tree). Faktor-faktor yang mempengaruhi keberhasilan mahasiswa pada tahap evaluasi adalah pilihan fakultas program studi s2, ipk s1, dan sumber biaya pendidikan. Mahasiswa yang memilih program studi berasal ilmu formal memiliki persentase kegagalan tertinggi dibandingkan yang memilih fakultas lainnya. Secara umum, faktor-faktor yang mempengaruhi keberhasilan lulusan mahasiswa magister adalah pilihan fakultas program studi s2, ipk s1, status perguruan tinggi s1, akreditasi program studi s1, letak perguruan tinggi s1, keserumpunan program studi, sumber biaya pendidikan, profesi, dan status perkawinan

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
