Judul: Perception of IPB Students about the Existence of  Snakes in Dramaga Campus IPB
Abstrak: Sebanyak 29 jenis ular yang ada di Kampus IPB Dramaga, 8 diantaranya jenis ular berbisa tinggi. Kasus gigitan ular pernah terjadi di kampus IPB Dramaga pada tahun 2021. Tujuan penelitian menganalisis pengetahuan dan sikap mahasiswa tentang ular yang ada di kampus IPB Dramaga. Data 374 reponden dari 9 fakultas dikumpulkan melalui google form dan analisis dengan membandingkan mahasiswa aktif di kegiatan Kelompok Pemerhati Herpetofauna (KPH) dengan mahasiswa umum. Pengetahuan terhadap keberadaan ular di kampus sangat dipengaruhi oleh ketersediaan informasi dan kegiatan mahasiswa. Seluruh mahasiswa KPH pernah berjumpa langsung dengan ular, sedangkan mahasiswa non KPH hanya 52,9% yang pernah bertemu dengan ular di kampus. Sebanyak 7,2% mahasiswa non KPH dan 58,6% mahasiswa KPH mampu mengidentifikasi jenis ular berbisa dan tidak berbisa dengan benar. Mahasiswa non KPH ada yang merasa takut dan merasa jijik jika melihat ular. Data tersebut menunjukkan perlunya edukasi mengenai ular bagi mahasiswa., Twenty-nine species of snakes accurs on the IPB Dramaga Campus, 8 of which are highly venomous. Snake bite cases have occurred on the IPB Dramaga campus in 2021. The purpose of the study was to analyze students' knowledge and attitudes about snakes on the IPB Dramaga campus. Data from 374 respondents from 9 faculties were collected through google form and analyzed by comparing active students in the Herpetofauna Observation Group (KPH) activities with general students. Knowledge of snake presence on campus was strongly influenced by information availability and student activities. All KPH students had direct encounters with snakes, while only 52.9% of non-KPH students had encounters with snakes on campus. A total of 7.2% of non-KPH students and 58.6% of KPH students were able to correctly identify the types of venomous and non-venomous snakes. There are non-KPH students who feel afraid and disgusted when they see snakes. This data suggests the need for snake education for students.

Judul: Students Knowledge of General Competency Education Program, Faculty of Veterinary Medicine, Bogor Agricultural University on Rabies
Abstrak: Rabies merupakan salah satu penyakit zoonotik yang disebabkan oleh virus golongan Mononegavirales, famili Rhabdoviridae, genus Lyssavirus yang berdampak pada sosial-ekonomi juga kesehatan masyarakat Indonesia. Tujuan penelitian adalah mengukur tingkat pengetahuan mahasiswa Program Pendidikan Kompetensi Umum (PPKU) Fakultas Kedokteran Hewan Institut Pertanian Bogor (FKH IPB) terhadap rabies, menguji hubungan karakteristik dan pengetahuan mahasiswa FKH IPB terhadap rabies. Penelitian dirancang menggunakan kajian lapang lintas seksional (cross-sectional study). Data diperoleh melalui google form yang disebarkan kepada responden menggunakan kuesioner yang sudah disusun secara terstruktur. Hasil penelitian menunjukkan bahwa sebagian besar mahasiswa PPKU FKH IPB yaitu 64,1% responden memiliki pengetahuan dengan kategori sedang, 16,1% responden dengan kategori baik, sedangkan 19,8% responden dengan kategori buruk. Dalam penelitian ini diperoleh bahwa tidak ada hubungan nyata antara jenis kelamin dan pengetahuan terhadap rabies (p=0,316), dan antara kepemilikan anjing dan pengetahuan terhadap rabies (p=0,4280). Hal ini mungkin terjadi karena responden pada penelitian ini diambil seluruhnya mahasiswa FKH., Rabies is one of the zoonotic diseases caused by mononegavirales virus, family Rhabdoviridae, genus Lyssavirus that has an impact on socioeconomic as well as public health in Indonesia. The purpose of the research was to measure the level of knowledge on Rabies in students of the General Competency Education Program of the Faculty of Veterinary Medicine, IPB University, determine the relationship between characteristics and knowledge. The research was designed using cross-sectional study. The data was collected through Google form that was distributed to respondents using a structured questionnaire. The results showed that the majority (64,1%) of General Competency Education Program Students of the Faculty of Veterinary Medicine, IPB University had knowledge with medium category, 16.1% respondents with good category, while 19.8% respondents with bad category. In this research it was found that there was no real relationship between sex and knowledge (p=0.316), and between dog ownership and knowledge (p=0.428). This result may be related to the respondents in this study which were taken entirely from the Faculty of Veterinary Medicine.

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.
