Judul: Knowledge of Students in Department of Horticultural Agronomy on Food Hygiene of Meat Balls in Babakan Raya, Dramaga, Bogor.
Abstrak: Produk pangan adalah segala sesuatu yang berasal dari sumber hayati atau air, baik yang diolah maupun tidak diolah yang diperuntukkan pada makanan atau minuman yang dikonsumsi manusia. Penelitian bertujuan mengukur tingkat pengetahuan mahasiswa Departemen Agronomi Hortikultura (AGH) Fakultas Pertanian (Faperta) Insitut Pertanian Bogor (IPB) tentang higiene pangan bakso di Babakan Raya, menguji hubungan karakteristik dan pengetahuan mahasiswa Departemen Agronomi Hortikultura tentang higiene pangan bakso di Babakan Raya, Dramaga, Bogor. Penelitian ini dirancang menggunakan kajian lapang lintas seksional (cross-sectional study). Data diperoleh melalui wawancara menggunakan kuesioner terstruktur dalam bentuk Google form yang disebarkan kepada responden. Data diperoleh dari 161 responden mahasiswa Departemen AGH Faperta IPB yang pernah membeli olahan pangan berupa Bakso di Babakan Raya, Dramaga. Data disajikan secara deskriptif dan dianalisis menggunakan uji Chi-square (χ2) untuk mengetahui hubungan antara karakteristik dan pengetahuan responden. Hasil penelitian menunjukkan adanya hubungan nyata antara frekuensi membeli dengan pengetahuan tentang higiene pangan bakso (p=0,001; p<0,05) dan pendapat kualitas pangan dengan pengetahuan tentang higiene pangan bakso (p=0,003); p<0,05), sedangkan antara jenis kelamin dan umur dengan pengetahuan tentang higiene pangan bakso tidak ada hubungan nyata (p>0,05).

Judul: Higiene Pekerja Kantin di Dalam Kampus Institut Pertanian Bogor Dramaga, Bogor
Abstrak: The aim of this study was to know the factors related with hygiene practices among food handlers at canteen in Bogor Agriculture University. Survey of KAP (knowledge, attitude, and practices) were used to know the relationship of knowledge and attitudes with their practices as its factors. Thirty nine food handlers were taken sampling randomly from sixty seven canteen in Bogor Agriculture University and become respondents for questionnaire about hygiene in handling food which is divided in to three aspect: personal hygiene, hygiene of production, and hygiene of facilities. The data were analyzed using the SPSS 16.0. A majority respondents have good knowledge (94.9%), attitude (100%), and practices (97.4%). Statistic analysis showed significant difference (p<0.05) between the relationship of knowledge, attitude, and main occupation with their practices

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.
