Judul: Identification suitability of implementation slaughtering sacrificial cows during the covid-19 pandemic in Serang City
Abstrak: Pemotongan sapi saat Idul Adha melibatkan berbagai lapisan masyarakat, sebagian besar dari mereka belum mengetahui pelaksanaan pemotongan yang sesuai aturan terutama di masa pandemi. Penelitian ini dilakukan untuk mengidentifikasi kesesuaian proses pelaksanaan kurban yang sesuai Surat Edaran Direktur Jenderal Peternakan dan Kesehatan Hewan Nomor 008 Tahun 2020 tentang pelaksanaan kegiatan kurban dalam situasi wabah bencana non alam corona virus disease (Covid-19) di empat lokasi di Kota Serang. Penelitian ini menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa persentase keseseuaian Surat Edaran Direktur Jenderal Peternakan dan Kesehatan Hewan Nomor 008 Tahun 2020 tertinggi adalah pada Komplek Ciceri Tahap 4 yaitu sebesar 76,5%, sedangkan persentase terendah adalah Komplek Permata dan Komplek Purna Bakti yaitu sebesar 58,8%. Aspek pemeriksaan antemortem dan postmortem, jaga jarak antara petugas penerapan protokol kesehatan dan disinfeksi seluruh peralatan merupakan aspek-aspek yang perlu diperbaiki sesuai Surat Edaran Direktur Jenderal Peternakan dan Kesehatan Hewan Nomor 008 Tahun 2020.

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.
