Judul: Knowladge of Quarantine Veterinarians in Balai Besar Karantina Pertanian Tanjung Priok About Food Safety and Food Quality
Abstrak: Karantina pertanian memiliki tugas dan fungsi dalam pencegahan masuk dan keluarnya penyakit ke dan dari wilayah Indonesia dan kepulauan di wilayah Indonesia. Sesuai dengan amanat Undang-Undang, salah satu ruang lingkup karantina pertanian adalah pengawasan dan/atau pengendalian keamanan pangan dan mutu pangan. Oleh karena itu, pengetahuan tentang keamanan dan mutu pangan perlu dimiliki oleh dokter hewan karantina. Penelitian bertujuan mengidentifikasi tingkat pengetahuan dokter hewan karantina terhadap keamanan dan mutu pangan. Data penelitian diambil melalui wawancara kepada dokter hewan karantina menggunakan kuesioner yang berisi 15 pertanyaan. Pengetahuan dokter hewan dikategorisasi menjadi tiga tingkat kategori, yaitu rendah, sedang, dan tinggi. Hubungan antara karakteristik responden dan tingkat pengetahuan dianalisis menggunakan uji Fisher exact. Hasil studi menunjukkan mayoritas (84,4%) dokter hewan karantina memiliki tingkat pengetahuan sedang, sedangkan tingkat pengetahuan tinggi sebesar 15,6% dan rendah sebesar 12,5%. Selanjutnya, diperoleh tidak ada hubungan antara umur, jenis kelamin, tingkat pendidikan, dan tingkat pengetahuan. Studi ini mengindikasikan masih diperlukannya peningkatan pengetahuan tentang keamanan dan mutu pangan untuk meningkatkan kinerja dokter hewan karantina., The agricultural quarantine has duties and functions in preventing the entry and exit of diseases into and from the territory of Indonesia and islands in the territory of Indonesia. In accordance with the mandate of the law, one of the scopes of agricultural quarantine is the monitoring and/or control of food safety and quality. Therefore, quarantine veterinarians should have knowledge on food safety and quality. The study aimed to identify the level of knowledge of quarantine veterinarians on food safety and quality. Data were collected through interviews to quarantine veterinarians using a questionnaire containing 15 questions. The knowledge level was categorized into three levels, i.e., low, moderate, and high. The relationships between respondent characteristics and knowledge level was analysed using Fisher exact test. The study showed that the majority (84,4%) of quarantine veterinarians had a moderate level of knowledge, while high knowledge level were 15,6% and low knowledge level were 12,5%. Furthermore, there was no relationship between age, gender, education level and knowledge level. This study indicates that there is still a need to increase the knowledge on food safety and quality to improve the performance of quarantine veterinarians.

Judul: Studi Pengetahuan, Sikap dan Praktik Kesejahteraan Hewan dan Biosekuriti pada Petugas Instalasi Karantina Hewan Primata Balai Besar Karantina Pertanian Soekarno Hatta
Abstrak: This study was conducted to analyze knowledges, attitudes and practices of installation personnels related to animal welfare and biosecurity to correlate knowledge, attitudes and practices of installation personnels to measure the level of animal welfare and biosecurity in animal quarantine installations. Data were collected from animal quarantine premises for exported primate (Macaca fasicularis). The level of knowledge, attitudes and practices of respondences measure by interviews and observation using the questionnaires and checklist. Data analyzed to determine associations between these variables using chi square and Gamma test. This research revealed that veterinarian knowledge correlated to their attitude with the level of correlation 0.694, and the care taker knowledge correlated to their attitude with the level of correlation 0.575. This study also noticed that the characteristics of respondents showed no correlation between animal welfare and biosecurity implementation, while the knowledge and attitude of veterinarians showed a strong correlation between animal welfare and biosecurity implementation with medium correlation level (r = 0.694). On the other hand the knowledge and attitude of care takers showed a strong correlation between the animal welfare and biosecurity with medium correlation level (r = 0.575). In conclusion most of the knowledge, attitude and practice of the veterinarians were verygood and knowledge, attitude and practice of the managers and care takers were good.

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.
