Judul: Evaluasi  Pelaksanaan  Good  Slaughtering  Practices  dan  Standard  Sanitation Operating Procedure  di Rumah Pemotongan Hewan Kelas  C
Abstrak: Nowdays consumers are more concern about food safety, therefore quality and food safety take the top place in food industri. Good Slaughtering Practices (GSP) and Standard Sanitation Operating Procedure (SSOP) are an integral component of process control and are often the first step in implemementation of food safety regulation. The objective of this research was to identified the evaluation of GSP and SSOP at C Class Slaugterhoues, to get NomorKontrol Veteriner (NKV) sertification. This research used descriptive analysis. Part of GSP and SSOP implementation has be done at slaugterhouse Sukabumi district but need to incrase facilities for efective and eficiency the GSP and SSOP implentation. Some of step Slaugther process has done match with GSP aspect but must incrase for better safety and quality. The result showed about 5,63-6,52 for value of pH. Keywords : GSP, SSOP, Slaughterhouse.

Judul: Application of Hygiene and Sanitation at Slaughterhouse in Margoyoso District Pati
Abstrak: Penerapan higiene dan sanitasi dilakukan untuk mencegah terjadinya kontaminasi pada daging. Tujuan penelitian ini mengevaluasi penerapan higiene dan sanitasi Unit Pemotongan Hewan di Kecamatan Margoyoso. Unit Pemotongan Hewan selanjutnya disebut dengan Tempat Pemotongan Hewan (TPH). Penelitian dilakukan merujuk pada penilaian kelayakan dasar Nomor Kontrol Veteriner. Penentuan lokasi dilakukan secara purposive sampling. Pengambilan data dilakukan dengan metode pengamatan dan wawancara. Data yang diperoleh dianalisis secara deskriptif. Terdapat 72 jenis indikator yang diamati pada setiap TPH. Hasil pengamatan pada TPH-1 ditemukan penyimpangan mayor sebanyak 20 jenis, penyimpangan minor sebanyak 36 jenis dan tanpa penyimpangan sejumlah 16 jenis, sedangkan pada TPH-2 ditemukan penyimpangan mayor sebanyak 18 jenis, penyimpangan minor terdiri atas 37 jenis dan tanpa penyimpangan 17 jenis. Berdasarkan hasil pengamatan TPH-1 dan TPH-2 dikategorikan pada tingkat III (cukup). Penerapan higiene dan sanitasi pada 2 TPH Kecamatan Margoyoso masih jauh dari sempurna. Perbaikan sarana dan prasarana serta pelatihan tentang pentingnya higiene dan sanitasi pada proses produksi perlu dilakukan, sehingga pelaksanaannya dapat lebih baik dan dapat meningkatkan kualitas produk., The implementation of hygiene and sanitation was to prevent contamination of meat. The purpose of this research was to evaluate the application of hygiene and sanitation at the slaughterhouse in Margoyoso District. The research was conducted based on the requirement of Veterinary Control Number. The slaughterhouse were called the TPH. Research location selection by purposive sampling. Data were collected by observation and interviews. The data obtained were analyzed descriptively. There are 72 items indicators was assessed. The results showed that TPH-1 found 20 items major deviations, 36 items minor deviations, and 16 items without deviations. While in TPH-2 found 18 items major deviations, 37 items minor deviations, and 17 items without deviations. Both slaughterhouses classified at level three (fair). The application of hygiene and sanitation at the slaughterhouses in Margoyoso District needs to be improved. The improvement on facilities, infrastructure and training on hygiene and sanitation were needed to improve the production processes and product quality.

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.
