Judul: Analisis Karakteristik dan Motivasi Mahasiswa IPB yang Mengalami Problematik Akademik
Abstrak: Institut Pertanian Bogor (IPB) merupakan salah satu perguruan tinggi yang bertujuan untuk menciptakan sumber daya manusia dan mutu pendidikan yang berkualitas. Salah satu indikator keberhasilan suatu program pendidikan dapat dilihat pada keberhasilan akademik mahasiswa. Keberhasilan akademik mahasiswa dapat dilihat berdasarkan ketepatan waktu mahasiswa dalam menyelesaikan masa studi. Keberagaman latar belakang memperlihatkan adanya karakteristik yang berbeda-beda dan beragamnya keaktifan dalam mengikuti perkuliahan menunjukan terdapatnya motivasi dalam diri mahasiswa. Kedua hal tersebut menjadi penting untuk dikaji sebagai evaluasi dalam merencanakan metode pembelajaran sehingga dapat mengurangi problematik akademik yang dihadapi mahasiswa dan tercapainya keberhasilan akademik. Metode yang digunakan untuk melihat karakteristik mahasiswa adalah dengan analisis deskriptif dan gambaran motivasi mahasiswa dalam menyelesaikan studi menggunakan metode analisis faktor yaitu Exploratory Factor Analysis dan Confirmatory Factor Analysis. Hasil yang didapatkan dari Exploratory Factor Analysis menunjukan bahwa terdapat enam faktor yang memengaruhi motivasi mahasiswa dengan keragaman total yang mampu dijelaskan sebesar 47%. Nilai tersebut menunjukan bahwa adanya faktor lain yang dapat dikaji dalam studi lebih lanjut. Kontribusi terbesar pada variabel motivasi mahasiswa adalah efikasi diri (70,8%) yaitu keyakinan dan kepercayaan mahasiswa akan kemampuannya dalam mengontrol hasil dari usaha yang dilakukan., Bogor Agricultural University (IPB) is one of the universities that aims to create human resources and quality education. One indicator of the success of an educational program can be seen in the academic success of students. Student academic success can be seen based on the timeliness of students in completing the study period. The diversity of backgrounds shows different characteristics, and the variety of activities in attending lectures shows that students are motivated. These two things are essential to be studied as evaluations in planning learning methods to reduce academic problems faced by students and achieve academic success. The method used to see the characteristics of students is descriptive analysis and a description of student motivation in completing the study using factor analysis methods, namely Exploratory Factor Analysis and Confirmatory Factor Analysis. The results obtained from Exploratory Factor Analysis show that six factors influence student motivation with a total diversity that can be explained by 47%. This value indicates that other factors can be studied in further studies. The most significant contribution to the variable of student motivation is self-efficacy (70,8%), namely student’s confidence and belief in their ability to control the result of the efforts made.

Judul: Kajian Indikator Motivasi Dalam Memilih IPB Pada Mahasiswa Angkatan 50
Abstrak: Bogor Agricultural University (IPB) is one of higher education providers services in Indonesia. IPB much in demand among the community as a place to gain an education. This is shown by the increasing number of applicants each year in IPB. The aim of the research was to analyze the motivation of students IPB in choosing IPB as a place to gain higher education and knowing the dominant factor which could affect the decision in choosing IPB. The study used a survey method. Factor analysis was a multivariate method used to analyze the variables that allegedly related with one to another so that relation can be described and mapped or grouped on the right factors. The results of the research indicated that the dominant motivating factor in choosing IPB as continuing education was because IPB accreditation status with total of eigen value is 7,929 or 22,654%. The results from SEM showed that students IPB (2013/2014) more internally motivated than externally., services in Indonesia. IPB much in demand among the community as a place to gain an education.

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.
