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: Implementation Management System on Slaughterhouse Category I as an Effort to Fulfill Safe Requirements Meat Product
Abstrak: Rumah potong hewan harus menghasilkan daging yang memenuhi syarat aman, sehat, utuh, dan halal. Persyaratan keamanan dasar yang harus diperhatikan pada saat proses produksi yaitu penerapan sistem manajemen terutama higiene dan sanitasi baik itu fasilitas/peralatan maupun higiene personal serta sumber daya manusia yang berwenang di rumah pemotongan hewan (RPH). Tujuan dari penelitian ini adalah untuk mengevaluasi penerapan higiene dan sanitasi supaya menjamin keamanan daging sapi yang dihasilkan dari RPH Kategori I Kabupaten Bogor. Pengamatan terhadap pelaksanaan higiene sanitasi dilakukan dengan menggunakan matriks evaluasi kesesuaian persyaratan fisik dengan metode penilaian parameter kriteria berdasarkan Peraturan Menteri Pertanian Nomor 13/2010. Nilai kesesuaian (NK) yang diperoleh berdasarkan matriks evaluasi adalah prosedur pemotongan sebesar 236 (sesuai), sumber daya manusia sebesar 135 (tidak sesuai), dan persyaratan fisik sebesar 215,5 (kurang sesuai). Hasil pengujian pada daging untuk kandungan Salmonella sp. negatif dan uji TPC antara 7,1 × 103 - 5,2 × 104 cfug-1 di bawah ambang batas SNI yaitu 1,0 × 106 cfug-1. Pengujian Escherichia coli pada daging berada di atas ambang batas diduga karena kontaminasi dari air yang digunakan. Validasi praktik higiene sanitasi dilakukan dengan cara swab Coliform pada pisau, telapak tangan dan pakaian petugas. Uji colliform swab telapak tangan petugas yaitu 5,4 × 102 cfug-1 menunjukkan nilai diatas ambang batas yang diperbolehkan. Hasil evaluasi penerapan sanitasi dan higiene di RPH sudah cukup baik namun masih perlu perbaikan. Perbaikan yang diprioritaskan adalah peralatan fasilitas kebersihan, pengujian kualitas air dan peningkatan pemahaman personal higiene.

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.
