Judul: Pengetahuan dan Sikap Masyarakat Desa Babakan Kecamatan Dramaga Kabupaten Bogor terhadap Kucing Liar dan Cara Pengendaliannya
Abstrak: Penelitian ini bertujuan untuk mengetahui seberapa jauh tingkat pengetahuan dan sikap masyarakat Desa Babakan terhadap kucing liar dan cara pengendaliannya. Pengambilan data dilakukan di Desa Babakan dari bulan Oktober 2014 sampai bulan Januari 2015. Pengambilan data dilakukan dengan menggunakan kuesioner kepada 100 responden. Data karakteristik responden yang diambil yaitu usia, jenis kelamin, wilayah, pendidikan, kepemilikan hewan peliharaan dan keberadaan kucing liar di lingkungan. Hasil penelitian menunjukkan lebih dari separuh (58%) responden memiliki pengetahuan yang cukup terhadap kucing liar dan terdapat 42% responden yang memiliki pengetahuan yang buruk terhadap cara pengendaliannya. Hasil analisa kategori sikap menunjukkan bahwa sebagian besar responden memiliki sikap positif terhadap kucing liar (84%) dan sikap netral terhadap cara pengendaliannya (53%). Karakteristik yang berkorelasi dalam penelitian ini adalah pendidikan dan wilayah. Pendidikan berkorelasi dengan pengetahuan masyarakat terhadap kucing liar dan sikap masyarakat terhadap cara pengendalian, sementara wilayah berkorelasi dengan pengetahuan masyarakat terhadap cara pengendalian dan sikap masyarakat terhadap kucing liar. Sebagian besar responden setuju (79%) steril/kebiri sebagai cara untuk mengendalian populasi kucing liar dan sebanyak 67% responden bersedia berperan aktif untuk melaporkan kelebihan populasi kucing liar ke pemerintah untuk ditindaklanjuti.

Judul: Tingkat Pengetahuan Pemilik Kucing di Kota Bogor terhadap Kesejahteraan Hewan dan Keterkaitannya dengan Kondisi Kesehatan serta Manajemen Pemeliharaannya.
Abstrak: Keep a pet is one of popular hobby in this society today. This research provides information the knowledge of cat owners in Bogor City about animal welfare. The data taken by using questionnaire to 50 respondents from five villages in Bogor City, from April 2014 until September 2014. The electoral wards and respondents conducted in purposive method. Respondents were classified based on income, education, age, gender, domicile (villages) and the number of cats. Cat welfare status observed based on the physical condition which includes body condition score, skin disease, wounds, limping, and worm infestation. The results of this research showed most respondents had high (62%), medium (36%), and low (2%) knowledge of animal welfare. Observations regarded the condition of overall the cat body can be said good. There were a significant relationship between knowledge with one aspect of characteristic respondents (the number of cats) and cat health management (vaccines). There is no significant relationship between knowledge with cat maintenance management.

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.
