Judul: Kajian Teknoekonomi Agroindustri Coconut Jerky “Cocobites”di Indonesia dengan Fuzzy Linear Programming.
Abstrak: Indonesia merupakan salah satu penghasil kelapa terbesar di dunia. Umumnya kelapa Indonesia diekspor dalam bentuk kelapa butir, minyak kelapa,dan kelapa kering. Salah satu produk turunan kelapa yang sedang dimintai pasar di negara maju yaitu produk Coconut Jerky.Produk Coconut Jerky merupakan produk berbahan dasar daging buah kelapa yang dikeringkan. Dengan bahan baku kelapa yang melimpah di Indonesia maka agroindustri Coconut Jerky sangat potensial untuk didirikan. Berdasarkan beberapa kriteria investasi proyek pada aspek finansial diperoleh nilai Net Present Value Rp 6.156.639.066 dengan discount rate sebesar 13,5%, Internal Rate Return diperoleh sebesar 118,83%, net B/C 5,89, dan payback period selama 10 bulan, hal tersebut menunjukkan bahwa agroindustri Coconut Jerky layak untuk didirikan. Kemudian untuk menentukan kapasitas produksi Coconut Jerky digunakan metode Fuzzy Linear Programming sehingga dapat memberikan keuntungan maksimum pada perusahaan yaitu sebesar Rp 403.462.026,- dengan memproduksi produk Coconut Jerky Ginger Teriyaki 2,5 oz diproduksi sebanyak 12.969 unit, produk Coconut Jerky Original 1,5 oz diproduksi sebanyak 13.284 unit, dan produk Coconut Jerky Chili Lime 1,5 oz sebanyak 13.284 unit.

Judul: Strategi pemasaran produk agroindustri kelapa berorientasi ekspor
Abstrak: Indonesia has the largest coconut area in the world, about 3,85 million hectare. It is also the biggest producer of coconut in the world, that produce around 16,498 billion nuts equivalent (3,3 million ton in copra equivalent). However, this situation does not mean that Indonesia become the biggest exporter of coconut agro-industry product in the world. The export value of coconut agro-industry products of Indonesia is only about 65,5% of total Philippine exports of coconut agro-industry products in 2009. In fact, Indonesia and the Philippines have the similar characteristics and plantation development patterns that are mostly done by the farmer themselves. Therefore, this research purpose is to determine prospective of coconut agro-industry product to be developed in export market with Exponential Comparative Method, to determine potential market of the prospective products with Analytical Hierarchy Process, and to formulate marketing strategy for coconut agro-industry product export oriented with Boston Consulting Group (BCG) matrix, Internal Factor Evaluation (IFE) matrix, External Factor Evaluation (EFE) matrix, Internal-External matrix, and Strength-Weakness-Opportunity-Threat (SWOT) matrix. The result indicated the selection of prospective products with Exponential Comparative Method showed that desiccated coconut (DC) are the most prospective product with the main potential market is China. Based on research result, the best market strategy to increase export value of coconut agro-industry products are replanting the coconut area, increase production process efficiency, increase quality of the products, create government organization to arrange export of coconut products from minor industries and farmers, active to attend coconut exhibitions in potential markets, develop export market to other countries, like USA, East Europe, and China, and develop more value-added products.

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.
