Judul: Analisis Biaya Pada Produksi Teh Hitam Orthodox di PT. Perkebunan Nusantara VIII Kebun Cisaruni, Garut Jawa Barat
Abstrak: This study has several purposes namely: (1) Study of tea production cost structure at PTPN VIII, Kebun Cisaruni. (2) Determined the break event point using cost analysis. (3) Feasibility study of tea production using Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit Cost Ratio(B/C) approch. The method of study used was descriptive method through case study. .Data collected were in form interviews with Managerial level and employe of the company and secondary data in form of literature study. The main results of this study are (1) Cost analysis shown that total cost production was IDR 19,627,388,655 and base price of tea production was IDR 10,141/kg that is still lower than selling price IDR 14,720/kg that give company margin IDR 4,579 of each kg of tea sales. (2) This study also shown the break even point of tea production at 1,333,382 kg, while total production of tea at the company reach 1,935,400 kg. That means tea production already at profit level. (3) While feasibility study of tea production shown that the business is feasible with NP Value IDR 33,24,.363,263 at discount factor 12% for 10 years period. While the IRR is 44,7 % and Net B/C ratio 1,254.

Judul: Analisis stuktur biaya produksi dan harga pokok teh hitam
Abstrak: Masalah yang dihadapi pasaran teh dunia adalah peningkatan produksi yang tidak di imbangi dengan konsumsi, akibatnya timbul ekses penawaran dan rendahnya harga teh. Pasaran teh Indonesia masih kecil terhadap volume ekspor teh dunia (6 persen) sehingga menyebabkan Indonesia sebagai "price taker". Masalah lain yang dihadapi pertehan Indonesia adalah harga jual yang cenderung menurun sedangkan biaya produksi cenderung meningkat. Dengan posisi Indonesia seperti diatas, dimana harga sangat ditentukan oleh harga jual pasaran dunia maka untuk tingkat kebun, salah satu cara untuk memperoleh keuntungan yang lebih besar adalah dengan menekan biaya produksi dan harga pokok serendah mungkin agar laba yang di peroleh semakin besar. Tujuan penelitian adalah untuk mempelajari sistem pengelolaan perkebunan teh sebagai perusahaan pertanian, terutama ditekankan pada penelaahan biaya produksi dan harga pokok teh hitam pada perkebunan Ciater PT Perkebunan XIII, Kabupaten Subang, Jawa Barat...

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.
