Judul: Evaluasi Proses Penanganan dan Pemotongan Sapi saat Idul Adha 1433 H (Studi Kasus di Wilayah Bogor dan Sekitarnya)
Abstrak: Cattle slaughter at Idul Adha was done voluntarily by citizen, most of them do not know the procedures of slaughtering. This research was conducted to identify critical point in cattle slaughter at Idul Adha in Bogor, Bekasi and Tangerang. This research used descriptive analiysis. Evaluation based on layout of slaughter area, sanitation and hygiene, personal hygiene, facility and slaughter process. Observation indicated that the critical point of slaughter process were slaughter process, skinning, eviceration, deboning, packaging and distribution

Judul: Analysis of the Implementation of Cattle Slaughter at Sacrificial Animal Slaughterhouses in Bandung Regency According to Government Regulations
Abstrak: Hari raya Idul Adha, dilakukan pemotongan hewan kurban secara serentak di sekitar area masjid. Penelitian ini bertujuan mengidentifikasi kesesuaian pelaksanaan pemotongan hewan kurban di empat lokasi di Kabupaten Bandung terhadap Peraturan Menteri Pertanian Republik Indonesia Nomor 114/Permentan/PD.410/9/2014 tentang Pemotongan Hewan Kurban. Digunakan metode analisis deskriptif pada penelitian ini. Hasil penelitian menunjukkan bahwa proses pelaksanaan pemotongan hewan kurban yang paling baik terdapat di Komplek Parahyangan Kencana dengan persentase kesesuaian sebesar 69,45% (kategori baik), sedangkan lokasi pemotongan hewan kurban dengan persentase terendah adalah Komplek Sanggar Indah Lestari dengan nilai persentase kesesuaian sebesar 50% (kategori kurang). Persentase kesesuaian terendah sebesar 0%, didapati pada aspek pemeriksaan antemortem, pemeriksaan postmortem, dan sanitasi dan higiene personal. Secara keseluruhan, pelaksanaan pemotongan sapi sudah dilakukan dengan cukup baik, meskipun bila dilihat dari beberapa aspek masih ada yang belum terpenuhi., Eid Adha, sacrificial animals are slaughtered simultaneously around the mosque area. This research aims to identify the suitability of the implementation of sacrificial animal slaughter in Bandung Regency with the Regulation of the Minister of Agriculture of the Republic of Indonesia Number 114/Permentan/PD.410/9/2014 concerning the Slaughter of Sacrificial Animals. This research uses a descriptive analysis method. The results showed that the best slaughtering of sacrificial animals occurred at the Parahyangan Kencana Regency with a compliance percentage of 69,45%% (good category). Meanwhile, the Sanggar Indah Lestari had the lowest percentage, namely 50% (less category). The lowest percentage of conformity value, namely 0%, was found in the aspects of antemortem examination, postmortem examination, and sanitation and personal hygiene. Overall, the implementation of cattle slaughter has been carried out quite well, although there are still some aspects that have not yet been fulfilled.

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.
