Judul: Pengaruh Pengetahuan dan Motivasi Mahasiswa terhadap Minat Beli produk Madoe honey IPB
Abstrak: Pengetahuan dan motivasi merupakan faktor yang memengaruhi minat beli. Tujuan penelitian ini adalah untuk mengetahui pengaruh pengetahuan dan motivasi konsumen terhadap minat beli produk Madoe honey IPB. Penelitian ini menggunakan desain cross sectional study yang dilakukan di IPB Dramaga, Jawa Barat pada bulan April 2014. Jumlah contoh 200 orang yang dipilih secara acak sederhana dengan jumlah proporsional berdasarkan fakultas. Pengetahuan mahasiswa tentang produk Madoe honey IPB tergolong masih rendah. Sedangkan motivasi mahasiswa memiliki motivasi yang cukup. Sebanyak 61,5 % mahasiswa berminat untuk membeli produk Madoe honey IPB. Pengetahuan dan motivasi memiiki hubungan dengan minat beli. Dari hasil uji pengaruh menunjukkan bahwa pengetahuan berpengaruh negatif signifikan terhadap minat beli artinya semakin tinggi pengetahuan maka minat beli akan semakin rendah sedangkan motivasi berpengaruh positif signifikan terhadap minat beli artinya semakin tinggi motivasi mahasiswa maka semakin tinggi pula minat beli.

Judul: Pengaruh Kelompok Acuan dan Pengetahuan terhadap Minat Beli Produk Pangan IPB pada Mahasiswa Program Sarjana
Abstrak: Bogor Agricultural University (IPB) is one of the university that produce many inovation product both in agriculture technology and foods. The purpose of this study was to analyze the influence of reference groups and knowledge toward intention to buy IPB’s food products on undergraduate students. The location of the research was in IPB Dramaga Bogor, West Java, in May 2012. Sampling technique that conducted in this research was simple random sampling and involved 400 students from all faculties in IPB as samples/participant. The data were analyzed using Chi-Square test, Pearson correlation, simple linear regression, and multiple linear regression. The results showed that one of the reference groups that most widely chosen was close friend (33,6%). More than half of the students were in a good enough categorized of knowledge (59,0%) and intention to buy (78,2%) IPB’s food product. Based on Pearson correlation test, reference groups had no correlation with knowledge (p=0,364) and intention to buy (p=0,376). However, knowledge had a positive and significantly correlated with intention to buy IPB’s food product (p=0,043). The result of regression test showed that intention to buy IPB’s food product effected by income (p=0,002) and knowledge (p=0,043)

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
