Judul: Strategi Promosi Rumah Tempe Indonesia, Bogor
Abstrak: Tempe merupakan makanan asli Indonesia yang dikenal sejak berabad-abad yang lalu. Bagi masyarakat Indonesia, saat ini tempe masih menjadi pilihan sebagai sumber protein. Sayangnya, masih banyak pengrajin tempe di Indonesia yang belum memenuhi bahkan memperhatikan standar pembuatan tempe ini. Hal ini membuat tempe dipandang sebagai makanan kelas bawah. Rumah Tempe Indonesia (RTI) berusaha memperbaiki citra tempe sebagai makanan sehat juga bisa diproduksi dengan cara yang baik pula, sehingga tempe yang dihasilkan merupakan makanan yang berkualitas. RTI memiliki visi mendorong perubahan dan memperbaiki kualitas dan citra tempe. Untuk itu, RTI perlu strategi promosi yang tepat agar visi dan misinya tercapai. Penelitian ini bertujuan untuk merumuskan dan merekomendasikan strategi promosi yang paling tepat untuk RTI dengan mempertimbangkan lingkungan internal dan eksternal. Metode yang digunakan pada penelitian ini adalah matriks SWOT dan AHP. Dihasilkan empat alternatif strategi dari matriks SWOT. Strategi WO: optimalisasi media sosial dengan melibatkan FTI dan konsumen merupakan alternatif dengan bobot tertinggi berdasarkan pengolahan AHP. Strategi ini yang kemudian menjadi rekomendasi strategi promosi bagi RTI.

Judul: Strategi Pemasaran Rumah Tempe Indonesia di Bogor
Abstrak: Rumah Tempe Indonesia (RTI) is one of food processing industries in Bogor which using soybean as raw material. Tempeh and tofu are main products of RTI. Recently, lack of optimization of marketing, limitation of resources, and also lack of optimization of machine used are the kinds problems of RTI. The purpose of this study is to formulate the appropriate marketing stategy through the marketing mix concept of 4P’s which involve the internal and external parties in organization. Analytic Hierarchy Process (AHP) was used as the method to solve the problems through the selection of several priorities. Result showed that the order of marketing mix priority that has been chosen by the internal parties are as follow : product, promotion, place, and price. Also, the ultimate goal can be determined by several criteria of marketing mix. Those criteria are quality, personal selling, direct distribution and above-market pricing.

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.
