Judul: Evaluation the Application of Slaughter Chicken Techniques that Observated from Food Safety and Halal Food in Slaughter Houses at Four Subdistricts of Bogor
Abstrak: Many of slaughter houses in Bogor still not appropiate to regulation of Indonesian National of Standarditation (SNI 01-6160-1999) that can causes contamination to carcass that produce in those slaugter houses. The equipments, the techniques of slaughter and the handling practices still not comply to request of sanitation and hygiene. The objective of this study was to evaluate the application of slaughter chicken technique that observated from food safety and halal food in slaughter houses in four subdictricts of Bogor. The experiment was used t-test to compare two types of slaughtering houses (coached and not coached) in building expedience, bacteria contamination and halal slaugtering. The results showed that the building expedience was significantly different (P>0,05) between those two tyes of slaughtering houses. The halal slaugtering practice was not significantly different for those two types of slaughtering houses. TPC contamination for all slaughtering houses was underneath from standard BMCM of SNI, except for not coached slaughtering houses of Dramaga was over than 1x106cfu/g. The coliform contamination for all slaughtering houses was over than 1x102cfu/g, but the numeric for TPC and coliform of coached slaughtering houses more better than not coached slaughtering houses. This evaluation of slaughtering houses showed that all slaughtering houses did not yet implemented the good slaughtering practice and good sanitation and hygiene practice totally.

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.
