Judul: Analisis Faktor-Faktor yang Memengaruhi Prestasi Mahasiswa pada Departemen Manajemen FEM IPB
Abstrak: IPB berada pada empat besar peringkat Kementerian Riset dan Pendidikan Tinggi selama tiga tahun berturut-turut, namun IPB masih memiliki peringkat kemahasiswaan yang terendah dibandingkan tiga universitas lain dalam peringkat tersebut. Salah satu komponen nilai kemahasiswaan adalah prestasi mahasiswanya. Penelitian ini bertujuan untuk 1) mengidentifikasi karakteristik mahasiswa yang berprestasi, 2) menganalisis persepsi mengenai faktor-faktor yang memengaruhi prestasi mahasiswa, 3) menganalisis pengaruh antara faktor-faktor yang memengaruhi prestasi mahasiswa terhadap prestasi mahasiswa, 4) mengidentifikasi Net Promoter Score alumni terhadap IPB. Studi kasus pada penelitian ini adalah alumni Departemen Manajemen FEM IPB. Data yang digunakan dalam penelitian ini adalah data primer dan sekunder. Sedangkan, metode yang digunakan adalah analisis deskriptif, SEM-PLS, dan Net Promoter Score. Hasil penelitian ini menunjukkan bahwa faktor lingkungan, fisiologis dan psikologis memengaruhi prestasi mahasiswa secara signifikan.

Judul: Analisis Faktor Eksternal dan Internal yang Mempengaruhi Prestasi Mahasiswa (Studi Kasus Alumni Program Sarjana Manajemen FEM IPB)
Abstrak: Student achievement not only rated by the GPA, but affective, cognitive and also pshychomotor. To achieve the third component and to get good GPA there is several factors affecting achievement process both external and internal factors. Analyze factors needs to be done to know factors that affecting students achievement with case studies of alumni Management FEM IPB. SEM test with SmartPLS software can be assessed that factor instrumental and psychological is the most influential with each of the T-statistic value are 3,203 and 5,554. Instrumental is an external factor that deliberately design as affecting factor process and learning factor that described by the administration, lecturer, curriculum and facility. Psychological is an internal factor establish how act or behavior of student in conscious or not that can be described by the talents, interests, intelligence, motivation, and cognitive abilities of student.

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.
