Judul: Analisis Sikap Konsumen dan Kinerja Atribut Sosis Kemasan Merek Fiesta di Wilayah Jabodetabek
Abstrak: Persaingan industri sosis kemasan yang ketat membuat produsen perlu memahami atribut yang dianggap penting oleh konsumen untuk merumuskan strategi pemasaran yang efektif. Penelitian ini bertujuan untuk mengidentifikasi proses keputusan pembelian, menganalisis sikap konsumen, dan menganalisis kinerja atribut sosis kemasan merek Fiesta sehingga dapat dijadikan evaluasi untuk perbaikan dan perkembangan produk. Penelitian ini menggunakan data primer yang diperoleh dari survei terhadap 156 responden. Data dianalisis dengan analisis deskriptif, multriatribut Fishbein, dan Importance Performance Analysis (IPA). Hasil penelitian ini menunjukkan bahwa konsumen melalui lima tahap proses keputusan pembelian, sikap konsumen terhadap seluruh atribut sosis kemasan merek Fiesta termasuk ke dalam kategori positif dan sangat positif, dan atribut sosis kemasan merek Fiesta tersebar ke dalam empat kuadran dengan variasi pilihan ukuran/isi, tekstur sosis, dan harga menjadi prioritas utama untuk diperbaiki., The tight competition in the packaged sausage industry means that producers need to understand the attributes that consumers consider important to formulate effective marketing strategies. This research aims to identify the purchasing decision process, analyze consumer attitudes, and analyze the performance attributes of Fiesta brand sausage packaging so that it can be used as an evaluation for product improvement and development. This research uses primary data obtained from a survey of 156 respondents. Data were analyzed using descriptive analysis, Fishbein multiattribute, and Importance Performance Analysis (IPA). The results of this research show that consumers go through five stages of the purchasing decision process, consumer attitudes towards all attributes of Fiesta brand packaged sausages are included in the positive and very positive categories, and the attributes of Fiesta brand packaged sausages are spread into four quadrants with variations in choice of size/filling, texture sausages, and prices are the main priority to improve.

Judul: Analisis preferensi konsumen di Toko Badranaya terhadap produk sosis dan implikasinya pada bauran pemasaran
Abstrak: The sausage business has a good potency, so that resulted in the huge business competition. One of the unit which produce sausage is Badranayas unit. Badranayas should apply the marketing concept which is consumer oriented. The application of this concept is determining mix marketing that consist of product, price, promotion and place. The aim of this research were to analyze the consumer attitudes of the vary atributes on sausage, to analyze the consumer preferences (attitudes) about the sausage and to arrange the alternative of mix marketing based on consumer preferences. The consumer preferences analysed from the consumer attitude value (Ao), this value used the Fishbein Multiatribut analysis, which consist of believeness (bi) and evaluation (ei) of the atibutes which put in sausage Badranayas. The offered sausage are special beef sausage, spesial chicken sausage and the super beef sausage. There are the same result of three products based on the consumer attitudes value, the likest atribute is labelling halal meanwhile that the dislikest one is promotion atribute. The implication of product mix are retaining halal labelling, labelling the date expired on all products, and increasing the various of sausage flavour. Implication of price mix are getting a discount of the products in certain days or to mantain the price, but with the following of the quality increasing. The implication of places mix are increasing the customer services and its comfortables when they shopped in the shop. Keywords : sausage, consumer preferences, mix marketing

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.
