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: 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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
