Judul: Business Development Strategy of Beef Cattle in Lembu Joyo Livestock Farmer Group Blora District
Abstrak: Kelompok Tani Ternak (KTT) Lembu Joyo merupakan kelompok yang memiliki usaha peternakan sapi potong di bidang pembibitan dan penggemukan, saat ini sedang mengalami penurunan kinerja dan jumlah ternak akibat dari pandemi covid-19, wabah PMK, dan penyakit lato-lato, sehingga memerlukan alternatif strategi yang tepat untuk diterapkan pada usahanya. Tujuan dari penelitian ini adalah untuk mengidentifikasi faktor-faktor internal dan eksternal yang memengaruhi usaha sapi potong KTT Lembu Joyo, merumuskan alternatif strategi yang tepat, dan menentukan prioritas strategi untuk dapat diimplementasikan. Metode yang digunakan pada penelitian ini adalah analisis deskriptif kuantitatif dengan alat analisis menggunakan matriks IFE dan EFE, matriks IE, matriks SWOT, dan QSPM. Hasil penelitian ini menunjukan faktor kunci internal utama meliputi sistem keanggotaan dan terhambatnya modal, sedangkan faktor kunci eksternal utama meliputi kerjasama kelompok ternak dan kebijakan impor. Alternatif strategi pengembangan yang dihasilkan terdiri dari enam alternatif strategi yang menjadi rekomendasi untuk pengembangan usaha dan mendapatkan prioritas strategi utama yaitu meningkatkan kualifikasi SDM dengan program pelatihan intensif., Lembu Joyo Livestock Farmer Group (KTT) is a group that has a beef cattle farming business in the field of breeding and fattening, is currently experiencing a decline in performance and the number of livestock due to the covid-19 pandemic, FMD outbreak, and lato-lato disease, so it requires the right alternative strategy to be applied to its business. The purpose of this study is to identify internal and external factors affecting KTT Lembu Joyo beef cattle business, formulate appropriate alternative strategies, and determine strategy priorities to be implemented. The method used in this research is quantitative descriptive analysis with analysis tools using the IFE and EFE matrix, IE matrix, SWOT matrix, and QSPM. The results of this research show that the main internal key factors include the membership system and capital constraints, while the main external key factors include livestock group cooperation and import policies. The resulting alternative development strategies consist of six alternative strategies which become recommendations for business development and receive the main strategic priority, namely improving HR qualifications with intensive training programs.

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.
