Judul: Analisis penyelenggaraan makanan dan tingkat kepuasan konsumen di Restoran Sate Tegal Laka-laka
Abstrak: Penelitian ini bertujuan untuk menganalisis penyelenggaraan makanan dan tingkat kepuasan konsumen di Restoran Sate Tegal Laka-laka. Penelitian ini bersifat studi kasus dan menggunakan analisis deskriptif. Metode penarikan sampel dilakukan secara purposive dan 91 konsumen digunakan dalam penelitian ini. Restoran Sate Tegal Laka-laka merupakan salah satu contoh penyelenggaraan makanan komersial dengan menu utama sate. Penyelenggaraan makanan di Restoran Sate Tegal Laka-laka terdiri dari perencanaan (anggaran) dan pelaksanaan (pengadaan bahan makanan, penerimaan, penyimpanan, pengolahan, dan penyajian). Penilaian higiene dan sanitasi merujuk pada Kepmenkes nomor 1098/Menkes/SK/VII/2003 tentang Persyaratan Higiene Sanitasi Rumah Makan dan Restoran. Restoran Sate Tegal Laka-laka mendapatkan skor 902 yang termasuk dalam tingkat mutu A. Berdasarkan hasil analisis Importance Performance Analysis (IPA) menunjukkan bahwa atribut cita rasa makanan/minuman yang disajikan dirasa paling penting dan dinilai paling tinggi tingkat kinerjanya. Berdasarkan Customer Satisfaction Index (CSI), diperoleh nilai kepuasan sebesar 77.79 (puas). Hasil uji korelasi menunjukkan adanya hubungan yang signifikan (p<0.05) antara tingkat pendidikan dengan penilaian atribut mutu produk., This research aimed to analyze food service and level of customers satisfaction in Sate Tegal Laka-laka Restaurant. Case study design was applied in this study and analyzed using descriptive analysis. Sampling method of purposive sampling was carried out and number of subjects used was 91 customers. Sate Tegal Laka-laka Restaurant is one example of the commercial food service with satay as the main menu. Food services in Sate Tegal Laka-laka Restaurant consist of planning (budget) and implementation (purchasing, receiving, storing, processing, and distributing). Assessment of hygiene and sanitation were based on Kepmenkes No. 1098/Menkes/SK/VII/2003 about Requirements of Hygiene Sanitation Restaurant. Sate Tegal Laka-laka Restaurant got score 902 were categorized in the quality level A. The result of analysis based on Importance Performance Analysis (IPA) showed that the taste of food/beverages served attributes was considered as the most important and had the highest rate performance levels. Based on the Customer Satisfaction Index (CSI), the satisfaction value was 77.79 (satisfied). There was a significant (p<0.05) correlation between education level with quality of the product.

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.
