Judul: Kajian Pemenuhan Regulasi Pelabelan Produk Olahan Daging di Beberapa Pasar di Kota Bogor
Abstrak: Food labelling is important part of food product. Label becomes a simple instrument for consumer to know about quality assurances on meat products. Labelling regulation in Indonesia uses PP 69 Tahun 1999. This reaserch aims to measure how far the implementation of food labelling in the market around of Bogor according to PP Nomor 69 Tahun 1999. The kind of this research is descriptive research and methodology used in this experiment is survey method with purposive sampling. Data processing is using tabulation, diagram, and histogram. Analysis towards to 63 samples of meat product from 12 locations in Bogor shows that 76.86% samples fullfil the technical of food labelling regulation. The data consist of 25,40% samples that display correct label in accordance of the technical regulation of food labelling, 84,13% samples that correct format content, 90.16% that provide minimum information, 90.19% samples that provide other form of information, and then 94,44% samples that fullfil the technical regulation of food labelling on prohibition in displaying of some restricted information.

Abstrak: This research was aimed to evaluate the degree of fulfillment of food product labels requirements by Small Medium Enterprises (SMEs) in Bogor compared with existing regulations (Indonesian Act Number 18 of 2012). Samples were chosen from three major SMEs products in Bogor, which were flour and its processed products; products from the process of grains and tubers; softdrink and powdered beverages. Four groups of elements were tested: (1) technical labeling, (2) content format, (3) minimum information displayed, and (4) prohibited information. The results showed the level of fulfillment for those three types of products were: (1) technical labeling: 44, 45, and 73%, (2) format content: 75, 80, and 60%, (3) minimum information: 71, 69, and 67%; and (4) not mention prohibited information: 99, 100, 96%, respectively. The average level of fulfillment for those three types of products were 72, 74, and 74%, respectively. This low level of fulfillment showed that further development of SMEs is needed, especially about food labelling criteria according to the existing regulations.

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.
