Judul: Ornamental Plant Business Development Strategy Analysis on CV Saung Amazon
Abstrak: CV Saung Amazon merupakan perusahaan yang bergerak di bidang tanaman hias yang penjualannya mulai menurun perlu membuat strategi baru untuk diterapkan. Tujuan dari penelitian ini adalah untuk mengidentifikasi faktor-faktor internal dan eksternal yang memengaruhi usaha tanaman hias pada CV Saung Amazon serta merumuskan rancangan strategi pengembangan usaha tanaman hias yang penting dan sesuai untuk CV Saung Amazon. Metode yang digunakan pada penelitian ini adalah analisis deskriptif kualitatif, matriks IFE dan EFE, Matriks IE, Matriks SWOT, dan Matriks QSPM. Hasil matriks IFE menunjukkan kekuatan utama perusahaan berupa treatment dan pengemasan tanaman yang baik dan kelemahan utama berupa pengurusan SIP Mentan yang memakan waktu lama. Hasil matriks EFE menyimpulkan peluang utama perusahaan ialah meningkatnya permintaan terhadap tanaman hias hibrida dan ancaman utama ialah kekuatan tawar-menawar pembeli yang kuat. Hasil matriks IE menyimpulkan bahwa perusahaan berada pada posisi pertahankan dan pelihara. Matriks SWOT menghasilkan enam alternatif strategi dengan prioritas strategi ialah peningkatan pemasaran dan promosi yang dianalisis menggunakan matriks QSPM., CV Saung Amazon is a company engaged in ornamental plants whose sales began to decline needs to create a new strategy to implement. The purpose of this study is to identify internal and external factors that affect the ornamental plant business in CV Saung Amazon and formulate a design of an important and suitable ornamental plant business development strategy for CV Saung Amazon. The methods used in this study are qualitative descriptive analysis, IFE and EFE matrix, IE Matrix, SWOT Matrix, and QSPM Matrix. The results of the IFE matrix show the company's main is good plant treatment and packaging and the main weakness is in the form of the Ministry of Agriculture's SIP management which takes a long time. The EFE matrix results conclude that the company's main opportunity is the increasing demand for hybrid houseplants and the main threat is the strong bargaining power of buyers. The results of the IE matrix conclude that the company is in a hold and maintain position. The SWOT matrix produced six alternative strategies with the priority of strategy is improving marketing and promotion which is analyzed using the QSPM matrix.

Judul: Business Development Strategy of  Horticulture Seed Industry in CV Nusa Heulang
Abstrak: Industri benih saat ini dan pada masa yang akan mendatang memiliki peluang yang besar di Indonesia, ditunjukkan dengan meningkatnya produktivitas produksi tanaman hortikultura yang berjalan seiring meningkatnya permintaan masyarakat terhadap produk hortikultura. Kondisi tersebut tidak diimbangi dengan perkembangan produsen benih lokal di Indonesia. Perusahaan multinasional dengan Penanaman Modal Asing (PMA) menjadi pemain inti dalam industri ini. CV Nusa Heulang sebagai perusahaan lokal dengan Penanaman Modal Dalam Negeri yang fokus dalam bisnis riset benih memerlukan rancangan strategi pengembangan usaha agar mampu berkontribusi lebih banyak dalam memenuhi permintaan tersebut. Tujuan dari penelitian ini untuk menganalisis faktor internal dan eksternal perusahaan sehingga dapat merumuskan beberapa alternatif strategi dan menetapkan prioritas strategi. Metode yang digunakan yaitu matriks IFE, EFE, IE, SWOT, dan QSPM. Matriks IFE dan EFE menunjukan bahwa CV Nusa Heulang memiliki posisi yang kuat untuk merespon kondisi lingkungan internal dan eksternal. Matriks IE menunjukan posisi perusahaan yaitu tumbuh dan membangun. Analisis SWOT menghasilkan enam alternatif strategi. Strategi prioritas yang dihasilkan dari matriks QSP adalah melakukan penetrasi pasar sehingga dapat menjangkau konsumen akhir., The seed industry currently and in the future has a great opportunity in Indonesia, as indicated by the increased productivity of horticultural crop production, which goes hand in hand with the increasing public demand for horticultural products. This condition is not supported by the development of local seed producers in Indonesia. Multinational companies with foreign direct investment (FDI) are the main players in this industry. CV Nusa Heulang as a local company with a domestic investment that focuses on the seed research business, requires a strategic business development plan in order to contribute more in fulfilling this demand. The purpose of this research is to analyze the company's internal and external factors to formulate several strategic alternatives and set strategic priorities. The methods the researcher used are the IFE matrix, EFE, IE, SWOT, and QSPM. CV Nusa Heulang is shown by the IFE and EFE matrices as having a strong position to respond to internal and external environmental conditions. The company's position is shown growing and developing by the IE Matrix. The SWOT analysis produces six alternative strategies. The priority strategy generated from the QSP matrix is to penetrate the market so that it can reach the end consumer

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.
