Judul: Penanganan dan Distribusi Karkas dan Non Karkas dari Tempat Potong Babi Jeletreng Gunung Sindur Bogor
Abstrak: The aimed of this study was to evaluate the technique of handling the carcass and non carcass at the abattoir, and to analyze the distribution of carcass and non carcass from an abattoir to the consumer. Data obtained from the observation of activities and interviews with owner and enterpreneurs of marketing using a questionnaire instrument. Data were analyzed descriptively. The results showed that the pig abbatoir Jeletreng, Gunung Sindur, Bogor has not check antemortem and postmortem; application of hygiene and sanitation not done well, packaging products made using plastic and no separation between the carcass and non carcass. The distribution line and marketing of carcass and non carcass pigs from producer to consumer marketing agencies that involve contractor merchants and retailers.

Judul: Evaluation of Meat Production and Handling Methods  at Poultry Slaughter Units in Traditional Markets
Abstrak: Preferensi konsumen terhadap daging unggas segar menyebabkan munculnya unit pemotongan unggas di pasar tradisional. Keamanan dan mutu daging unggas harus diperhatikan agar produk dapat dipasarkan sesuai persyaratan yang berlaku. Penelitian ini bertujuan mengevaluasi penerapan cara produksi dan penanganan daging pada unit pemotongan ayam di Pasar Tradisional Kota Bogor. Penelitian dilakukan berpedoman pada Standar Nasional Indonesia 99002:2016 tentang Pemotongan Halal pada Unggas dan Peraturan Kepala Badan Pengawas Obat dan Makanan Republik Indonesia Nomor 5 Tahun 2015 tentang Pedoman Cara Ritel Pangan yang Baik di Pasar Tradisional. Penentuan lokasi penelitian dilakukan secara purposive sampling yaitu di Pasar Gunung Batu, Bogor. Sampel yang digunakan adalah 5 responden pedagang ayam yang melakukan pemotongan langsung di kios. Pengambilan data dilakukan dengan metode pengamatan dan wawancara. Data yang diperoleh dianalisis secara deskriptif. Total nilai kesesuaian yang diperoleh sebesar 163 (54,33 %). Hasil evaluasi menunjukkan bahwa praktik pemotongan unggas dan higiene sanitasi belum sepenuhnya diterapkan dengan baik di pasar tradisional. Perbaikan sarana, prasarana dan pelatihan tentang proses pemotongan halal dan higiene sanitasi pada proses produksi perlu dilakukan, sehingga dapat menghasilkan daging ayam yang aman, sehat, utuh dan halal (ASUH)

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.
