Judul: Pengembangan Model Bisnis Manisan Cabai Merah (Capsicum annum)
Abstrak: Candied red chilli (Capsicum annuum) is one kind of processed vegetable innovation which added by sugar as natural preservative. The objective of research was to generate product profile and determine the best business model design. The method consisted of two stages such as of product profile development and business model development. Based on the result, candied chilli product has moisture content of < 15 %, red-colored and had combined sweet and few spicy flavor. Candied red chilli had met quality standard of dried candied product in SNI 01-3710-1995. Rate of diatery index (% RDI) of the product was 3 % of fat, 5 % of protein, carbohydrate content of 27 %, so that a single pack of 100 g could produce 18 % calori. The product was packaged using primary packaging by combination of aluminum foil and plastic PP (poly propilene) which was practical and easy to open. Initial business model was assumed based on sweets vegetables business models in Surabaya and sweets business in Bogor city. The business model changed after development of the best product profile and business model development phase such as problem and solution tests. Product profile development phase changed elements of business model such as key partnership, key activities, key resources and cost structure. Business model development phase changed four elements of business model such as customer segment, value propotions, channels and customer relationship. Final result of iteration changed former concept of the product to be more favored by consumers.

Judul: Design of Business Model for Vegetable Products at  Ciaruteun Ilir Vegetable Packaging House
Abstrak: Produk sayuran yang diproduksi oleh para petani di Desa Ciaruteun Ilir tidak sepenuhnya terserap oleh mitra mereka sehingga terdapat banyak sayuran yang tidak terjual. Para petani ingin langsung menjual kepada konsumen akhir agar dapat meminimalisir ketidaterserapannya sayuran yang masih tersisa. Produk Rumah Kemasan Sayuran Desa Ciaruteun Ilir belum dikenal sehingga pasar produk yang dimiliki belum optimal. Penelitian ini bertujuan untuk mengembangkan konsep produk dan model bisnis produk Rumah Kemasan Sayuran Desa Ciaruteun Ilir agar lebih diterima dan diinginkan oleh target pasar yang dituju. Penelitian ini terdiri dari tahap eksplorasi, ideasi, dan verifikasi. Segmen konsumen yang ditargetkan adalah masyarakat Bogor yang berusia produktif dari kalangan menengah ke atas. Solusi yang ditawarkan adalah konsep produk dan model bisnis Rumah Kemasan Sayuran Desa Ciaruteun Ilir yang menyediakan sayuran yang berkualitas, bervariatif, dan cara pascapanen yang baik, Vegetable products produced by farmers in Ciaruteun Ilir Village are not fully absorbed by their partners, so many unsold vegetables exist. Farmers want to sell directly to final consumers in order to minimize the non-absorption of the remaining vegetables. The product of the Ciaruteun Ilir Vegetable Packaging House is not yet known, so the market for its products is not optimal. This study aims to develop the product concept and business model of the Ciaruteun Ilir Vegetable Packaging House so that it is more accepted and desired by the intended target market. The research consists of stages of exploration, ideation, and verification. The targeted consumer segment is the productive age of the Bogor residents from the upper middle class. The solution offered is the product concept and business model of the Ciaruteun Ilir Vegetable Packaging House, which provides quality, varied, and good postharvest vegetables.

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.
