Judul: Kajian Strategi Pemasaran Sapi Potong di CV. Septia Anugerah Jakarta
Abstrak: CV Septia Anugerah is one beef cattle company in Indonesia that can meet the need for beef cattle. In west java, beef marketing is mostly dominated by cattle companies or feedlots. They greatly help farmers with the marketing of their livestock and make it easy for the farmers to get cash money when they need it. Marketing the beef cattle through a marketing channel can make the commodity reach the consumers. Yet an inefficient or relatively long channel of marketing can cause loss for both breeders and consumers. The consumers would bear high cost of marketing, thus pay higher price; while the breeders would get lower income because of lower selling price as well. The resulted total scores for the matrix IFE and EFE were respectively 2,696 and 2,793 indicating that CV Septia Anugerah is in a stable position to respond to external situation and in average position to respond to its internal factors. The total score value of both IFE and EFE was to identify the position of CV Septia Anugerah. The matrix value of IE pointed to the middle cell position (V), i.e. growth/stable. The result of SWOT analysis was in the form of a formulated strategy, namely, the need for the implementation of a combination of the four marketing aspects (4Ps: products, price, place and promotion). The managerial implications of the aspects under the study can be grouped into four: (a) marketing, (b) financing, (c) production, and (d) human resource. Based on the calculation of QSP matrix, the most interesting strategy to apply is to expand the marketing network by penetrating the market with the highest value of attraction (4,949).

Judul: Marketing Analysis of Beef Cattle in Napis Village, Tambakrejo District, Bojonegoro Regency, East Java.
Abstrak: Sapi potong merupakan salah satu dari delapan produk yang fokus dikembangkan sebagai bahan makanan pokok nasional untuk dikonsumsi dagingnya. Harga sapi potong cenderung berfluktuatif dan memilki marjin pemasaran yang tinggi. Penelitian ini bertujuan untuk menganalisis pemasaran dan tingkat efisiensi pemasaran. Metode penggumpulan data menggunakan simple random sampling untuk peternak dan snowball sampling untuk lembaga pemasaran. Hasil analisis menunjukan saluran yang relative lebih efisien adalah saluran 3 (peternak-pedagang pengumpul-pedagang pemotong lokal). Indikator efisiensi pemasaran adalah marjin pemasaran, farmer’s share, rasio keuntungan terhadap biaya, daya serap komoditas, fungsi-fungsi pemasaran, perilaku pasar, serta hubungan kerjasama antar lembaga yang terlibat dalam kegiatan pemasaran sapi potong di Desa Napis.

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.
