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: Knowledge of Quarantine Veterinarian in Balai Besar Karantina Tanjung Priok regarding Peste des Petits Ruminants
Abstrak: Peste des petits ruminants (PPR) merupakan penyakit yang disebabkan oleh virus menyerang hewan ruminansia, terutama ruminansia kecil seperti domba dan kambing. Penyakit PPR telah masuk ke dalam penyakit hewan menular strategis (PHMS) yang belum ada di wilayah Indonesia. Karantina hewan berperan dalam pencegahan penyakit hewan menular eksotik, sehingga dokter hewan karantina perlu memiliki pengetahuan tentang penyakit eksotik. Penelitian ini bertujuan untuk mengetahui tingkat pengetahuan dokter hewan karantina terhadap PPR. Penelitian ini dilakukan dengan menyebarkan kuesioner dengan bentuk Google form kepada dokter hewan karantina di Balai Besar Karantina Pertanian Tanjung Priok. Hasil kuesioner yang sudah dijawab oleh responden lalu dianalisis dengan bantuan software Microsoft excel dan SPSS for Windows. Uji yang dilakukan adalah uji Fisher exact untuk melihat hubungan antara karakteristik responden dengan tingkat pengetahuan responden. Hasil studi ini menunjukkan bahwa mayoritas responden (80,6%) masuk ke dalam kategori tingkat pengetahuan sedang, lalu tingkat pengetahuan rendah (13,9%), dan tingkat pengetahuan tinggi (5,6%). Hasil uji Fisher exact menyatakan bahwa tidak ada hubungan yang signifikan antara karakteristik responden dengan tingkat pengetahuan. Studi ini mengindikasikan masih diperlukannya peningkatan pengetahuan tentang PPR untuk meningkatkan kinerja dokter hewan karantina., Peste des petits ruminants (PPR) is a disease caused by virus that infects ruminants, especially small ruminants such as sheep and goat. PPR has been categorized as strategic animal infectious disease that does not yet exist in Indonesia. Animal quarantine plays a role in preventing exotic animal infectious diseases, so quarantine veterinarians need to have knowledge on exotic diseases. This study aimed to determine the level of knowledge of quarantine veterinarians on PPR. This research was conducted with interview to quarantine veterinarians using questionnaires (Google form) at Balai Besar Karantina Pertanian Tanjung Priok. The results of the questionnaire that had been answered by respondents were analysed using Microsoft excel software and SPSS for Windows. Fisher exact test was applied to describe the relationship between the characteristics of respondents and the level of the respondent’s knowledge. The study showed that most respondents (80,6%) were categorized in moderate knowledge level, meanwhile the low level of knowledge were 13,9%, and the high level of knowledge were 5,6%. Furthermore, there was no significant relationship between respondent characteristics and knowledge level in this study. This study indicated that there is a need to increase the knowledge on PPR to improve the performance of quarantine veterinarians.

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.
