Judul: Development Strategy Dairy Farm Production in Coastal Areas (Bangka Botanical Garden Pangkalpinang)
Abstrak: Bangka Botanical Garden (BBG) merupakan kawasan di Pulau Bangka yang didirikan pada tahun 2006 untuk menyediakan area agrowisata di Kota Pangkalpinang. Salah satu daya tarik BBG karena memiliki peternakan sapi perah dengan populasi ternak 153 ekor. Lokasi peternakan BBG memiliki keunikan karena kondisi peternakan yang dekat dengan daerah pesisir. Kondisi daerah BBG kurang ideal terhadap fisiologis ternak perah terutama sapi peranakan friesian holstein (PFH) sehingga perlu dikaji untuk perbaikan dan pengembangan BBG. Keberhasilan peternakan sapi perah dilihat pada efisiensi produksi susu baik secara kuantitas hingga kualitas. Kualitas susu segar telah diatur dalam Standar Nasional Indonesia (SNI) dan diharapkan peternakan sapi perah mencapai standar yang telah ada. Aspek penilaian peternakan sapi perah yang baik dapat dilihat pada performa individu ternak, produktivitas susu, manajemen pakan, lingkungan perkandangan, respons fisiologis ternak terhadap stress, dan kualitas susu hasil pemerahan. Indikator yang diamati dibandingkan dengan standar yang ada di Indonesia, lalu diamati kekurangan aspek dan dibuat strategi untuk meningkatkan produktivitas peternakan sapi perah di BBG. Metode penelitian evaluasi manajemen dilakukan secara deskriptif dengan prosedur pengambilan data menggunakan pengumpulan data yang telah ada dan dilakukan pengujian sampel susu. Indikator yang diamati dibandingkan dengan standar untuk mengetahui permasalahan yang terjadi. Analisis manajemen dilakukan dengan metode fault tree analysis (FTA) untuk menjabarkan permasalahan dan dampak secara deskriptif. Failure mode effect analysis (FMEA) merupakan analisis lanjutan FTA secara kuantitatif dengan metode house of risk (HOR) fase 1 dan fase 2. FMEA berfungsi untuk mengetahui kejadian risiko, agen risiko, serta menyusun strategi penanganan risiko. Penelitian bertujuan menghasilkan strategi pengembangan produksi ternak perah di BBG., Bangka Botanical Garden (BBG), an agro-tourism area in Bangka Island, was established in 2006 to provide an agro-tourism area in Pangkalpinang City. One of the vacilities in BBG is a dairy farm with a cattle population of 153 heads. The location of a dairy farm in BBG is unique because it is close to the coastal areas. BBG locations had not ideal conditions for dairy cattle's physiology, especially Friesian Holstein breed cattle (PFH). The success of dairy farming had seen in the efficiency of milk production both in quantity and quality. The quality of fresh milk has been regulated in the Indonesian National Standard (SNI), and it is hoped that dairy farming will reach the existing standards. A good assessment of dairy farming can be seen in livestock, milk productivity, feed management, housing environment, the physiological response of livestock in distress, and quality of milk produced. The indicators that were observed were compared with the existing standards in Indonesia. Then it was observed that there is a lack of aspects and strategies to increase the productivity of dairy farming on BBG. The management evaluation research method was carried out descriptively with data collection procedures using existing data collection and sample testing. The observed indicators were compared with the standard to determine the problems that occur. Management analysis method using the fault tree analysis (FTA) to describe problems also impacts. Failure mode effect analysis (FMEA) is continued analytical tools after FTA to quantitative data with house of risk (HOR) phase 1 and phase 2. FMEA used to find severity

Judul: Evaluation of Beef Cattle Breeding Management from Livestock Aid Grants
Abstrak: Upaya pengembangan sapi potong dalam rangka peningkatan produksi hasil peternakan dilaksanakan oleh Dinas Peternakan dan Kesehatan Hewan Kabupaten Pesisir Selatan melalui program bantuan ternak sapi potong yang diberikan pada kelompok ternak dengan tujuan untuk meningkatkan hasil ternak sehingga dapat meningkatkan pendapatan peternak. Penelitian ini bertujuan mengevaluasi penerapan manajemen pemeliharaan yang baik sesuai dengan standar GFP pada kelompok ternak penerima bantuan. Metode yang digunakan adalah wawancara dan observasi. Kuesioner meliputi pengetahuan reproduksi, manajemen pakan, tatalaksana pemeliharaan, kesehatan dan penyakit serta perkandangan. Dampak penerapan manajemen pemeliharaan diamati berdasarkan BCS sapi potong. Responden penelitian adalah 10 orang anggota kelompok ternak Pincuran Boga Sakato dan 15 orang anggota kelompok ternak Padang Dama II. Data dianalisis menggunakan metode analisis deskriptif. Hasil penelitian penerapan manajemen pemeliharaan pada kedua kelompok ternak mendapatkan kategori kurang, dengan persentase Pincuran Boga Sakato sebesar (49,95%) dan Padang Dama II (54,86%) Penerapan aspek yang perlu mendapat perhatian adalah pengetahuan reproduksi, tatalaksana pemeliharaan serta kesehatan dan penyakit ternak. Secara keseluruhan performa sapi di kelompok Padang Dama II lebih baik dari pada di kelompok Pincuran Boga Sakato., The efforts to develop beef cattle in order to increase livestock production are carried out by the Department of Animal Husbandry and Animal Health of Pesisir Selatan Regency through a beef cattle grant program to farmers groups with the aim of increasing livestock yields so as to increase farmer income. This study aims to evaluate the implementation of beef cattle management in accordance with GFP standards in groups of farmers. The method used consists of interview and observation. The questionnaire includes knowledge of reproduction, feed management, maintenance management, health and disease and housing. The impact of the implementation beef cattle management was observed based on the BCS of beef cattle. Research respondents were 10 members of the Pincuran Boga Sakato farmers group and 15 members of the Padang Dama II farmers group. Data were analyzed using method. The result of the study on the application of beef cattle management to both group of farmers were categorised in the less category (<60%), the percentage of Pincuran Boga Sakato (49,95%) and Padang Dama II (54,86%) The application of aspects that need attention is the knowledge of reproduction, maintenance management and health and disease of livestock. Overall, the performance of the beef cattle management in Padang Dama II farmers group was better than in the Pincuran Boga Sakato farmers group.

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.
