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: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
