Judul: Knowledge and Attitude of Foodborne Disease in Dairy Cattle of the Students in the Department of Community Nutrition IPB University Indonesia
Abstrak: Foodborne disease dapat terjadi akibat mengonsumsi makanan dan minuman yang sudah tercemar mikroorganisme patogen. Susu merupakan salah satu produk pangan asal hewan yang dapat mengakibatkan foodborne disease. Penelitian dilakukan dengan mengisi kuesioner secara online oleh responden yang berasal dari mahasiswa Departemen Gizi Masyarakat, Fakultas Ekologi Manusia IPB University. Tujuan penelitian ini adalah untuk mengetahui dan mengidentifikasi faktor yang memengaruhi tingkat pengetahuan dan sikap. Metode penelitian yang digunakan melalui teknik penarikan contoh acak berstrata dan dianalisis menggunakan uji Spearman Correlation untuk melihat hubungan karakteristik dan pengetahuan serta sikap responden. Hasil penelitian menunjukkan bahwa tingkat pengetahuan terkait foodborne disease pada susu sapi pada mahasiswa angkatan 55 (2018), 56 (2019), dan 57 (2020) Departemen Gizi Masyarakat, FEMA IPB University berada pada kategori cukup, sedangkan sikap berada pada kategori baik. Pengujian Spearman Correlation menunjukkan adanya hubungan antara angkatan dengan tingkat pengetahuan (P< 0,05). Berdasarkan hasil di atas kami menyimpulkan bahwa tingkat pengetahuan dan sikap responden terhadap foodborne disease pada susu sapi dipengaruhi oleh tingkat pendidikan, tingkat kesadaran, dan lingkungan sosial., Foodborne disease caused by consuming contaminated food and drink. One of the animal food products which possibly cause foodborne disease is a dairy milk. Research were done by an online questionnaire to students from Public Nutrition Department, Faculty of Human Ecology IPB University, with the purpose of knowing the knowledge and attitude levels of respondents. Research methods were done by stratified random sampling and data was analyzed by Spearman Correlation to determine the relationships between characteristics and knowledge and also attitude of the respondents. Result shows that the knowledge about foodborne disease in dairy milk from students batch 55 (2018), 56 (2019), and 57 (2022) in the Departement of Community Nutrition, Faculty of Human Ecology IPB University is adequate, while the attitude was category as good. Spearman Correlation shows that there is a correlation between student’s batch (year of entry) and knowledge level (P<0,05). We concluded that knowledge level and attitude of respondents to foodborne disease of dairy milk is affected by education level, awareness level, and social environment.

Judul: Pengetahuan dan sikap mahasiswa fakultas kedokteran hewan Institut Pertanian Bogor terhadap foodborne disease
Abstrak: This study was conducted to evaluate correlation between characteristics (sex, age, graduate level, entrance to Bogor Agricultural University, and activity on organisations), knowledge and attitude of Veterinary Students of Bogor Agricultural University on foodborne diseases. The data collection was carried out using quetionnaires for 239 respondents from August 2010 to January 2011 by stratified random sampling. The significant possitive correlation was observed between knowledge and age, graduate level, and activity on organisations (p<0.05), nevertheless sex and entrance to Bogor Agricultural University did not show a correlation with knowledge (p>0.05). The significant possitive was found between attitude and entrance to Bogor Agricultural University (p<0.05). In this study, the correlation between sex, age, graduate level, and activity on organisations and attitude were not found significantly (p>0.05). There was no correlation was observed between knowledge and attitude (p>0.05).

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.
