Judul: Pengembangan Pasar Produk Asinan Bogor dengan Metode Riset Aksi. Dibimbing
Abstrak: “Asinan Bogor” is one of an authentic cuisine from Bogor, which is favoured by many people. However, the product is rarely used as a gift especially for travelers who live far away. The objective of the study was to obtain the best business model by the action research method approach in “asinan Bogor” market development. Data were collected by interview method to 50 travelers coming to Bogor, in order to problem and solution tests on the product. Based on the problem test, 72% of the respondents were potential consumers having concerns about the product. The problems were consumer concerns on packaging, i.e. easy to leak, unhigiene product, product inconsistency (taste, volume, size, and texture of the fruit), a short shelf life, and less attractive packaging, making the product not common as gift or souvenir. Based on problem test result, business models were designed to suit the needs of the consumers. The result of the business model was 92% of respondents stated that the product branded as “Asinan Kujang” has been suitable as an indigenous Bogor souvenir.

Judul: Pengembangan Pasar Produk Beras Cepat Masak
Abstrak: Penelitian ini berawal dari permasalahan konsumsi yang dihadapi oleh komunitas pecinta alam. Tujuan dari penelitian ini yaitu mengidentifikasi masalah yang dihadapi pecinta alam saat membawa dan mengolah beras serta merancang solusi pada permasalahan tersebut dengan produk beras cepat masak. Metode yang digunakan pada penelitian ini adalah riset aksi dengan menggunakan pendekatan kualitatif. Tahapan dari penelitian terdiri dari perancangan kanvas model bisnis awal, pengujian masalah dengan 50 responden, pengujian solusi dengan responden potensial, pengukuran ukuran pasar, dan verifikasi. Permasalahan utama pada penelitian ini, yaitu berat saat membawa beras dan air, boros penggunaan air, membutuhkan perlakuan khusus saat memasak nasi, lama waktu memasak nasi, relatif sering gagal dalam memasak nasi dan alat masak (nesting) yang sulit dibersihkan. Beras cepat masak adalah produk yang ditawarkan untuk menjadi solusi dari permasalahan tersebut. Hasil pengujian solusi dari produk beras cepat masak menunjukkan kesesuaian value proposition yang diberikan kepada pelanggan yaitu praktis, tidak gagal dalam memasak nasi, tidak mengotori alat masak (nesting), hemat air dan tidak berat. Harga penjualan yang diterima oleh konsumen, yaitu Rp13.500/kemasan (6*42 gr).

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.
