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: Karakteristik Wisudawan Berdasarkan Indikator Kesuksesan Mahasiswa (Studi Kasus: Program Sarjana IPB)
Abstrak: Karakteristik dari mahasiswa yang sukses dapat dijadikan sebagai indikator untuk mengevaluasi program pendidikan. Indikator yang digunakan pada penelitian ini adalah indeks prestasi kumulatif (IPK) akhir, lama studi, dan predikat kelulusan. Beberapa pendekatan diimplementasikan untuk menganalisis karakteristik, yaitu analisis gerombol, analisis korespondensi berganda, dan regresi logistik biner. Analisis gerombol memberikan informasi departemen berdasarkan karakteristiknya. Hasil dari analisis gerombol yaitu terdapat empat gerombol departemen. Analisis korespondensi berganda memberikan informasi kedekatan variabel IPK TPB dengan variabel indikator keberhasilan yang lainnya. Beberapa variabel yang berpengaruh terhadap lama studi adalah jenis kelamin, beasiswa, jalur masuk dan TPB GPA. Hasil tersebut dianalisis dengan regresi logistik biner.

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.
