Judul: Kajian Kapasitas Puskesmas dalam Pengambilan Contoh Makanan Penyebab KLB Keracunan Pangan di Kabupaten Bogor
Abstrak: Food poisoning outbreak is one of the food safety issues that must be handled seriously. Most of the cases of food poisoning in Indonesia are not reported yet or they are reported but unknown causes. One attempt to solve the problem is through a good food handling by taking samples of food, tested them in the laboratory, then reported the cause of food poisoning outbreaks to the related agencies, such as puskesmas. The aim of this study is to assess the readiness of puskesmas in handling the outbreak of food poisoning in Bogor district based on the capacity of puskesmas to reduce the food poisoning outbreaks, such as its human resources, tools and available materials as well as types of puskesmas. The method used in this study is the primary data collection which is obtained from direct interview to respondens and guided by questionnaires. In addition, secondary data the number of puskesmas that have experienced food poisoning outbreak in Bogor district is gathered from the Dinas Kesehatan and food poisoning outbreak data is obtained from BPOM RI. Based on the result, 44 % of puskesmas have number human resources around 20 to 30. The tools and materials owned by the puskesmas did not reach 100%. Type of puskesmas influence the readiness of the puskesmas in handling and taking sample of food poisoning outbreak. Around 39.13 % of non rawat-inap type of puskesmas were categorized ready and only 13.04 % of rawat-inap type of puskesmas were categorized ready.

Judul: Kajian Kesadaran dan Perilaku Ibu Rumah Tangga Terhadap Keamanan Pangan di Kota dan Kabupaten Bogor
Abstrak: Housewife played an important role as household food safety gate keeper therefore study of food safety risk awareness as well as food safety behaviors and opinion to food regulatory system is needed as a basis for developing policies and interventions. Research method used was survey questionnaire method which used purposive sampling method. A total of 139 questionnaires were distributed to housewifes in Bogor. Genetically modified food, foodborne disease, and food iradiation were not considered yet but respondent gave enough attention to food safety risk. Vegetable vendors became first priority place for shopping and the price became the main aspects to be considered both for fresh and processed food. The most influential information source was television. Majority of respondents felt confident (57%) and satisfied (52%) with the performance of The National Agency af Drug and Food Control (NA-DFC). Respondents made food-handling errors especially on determining doneness of meat and preventing cross-contamination however food handling behavior towards application five keys of food safety was good with an average value of 3.99 out of 5 and a standard deviation of 0.37. Education levels and expenditure positively correlated with the behavior of respondents in implementing the five keys of food safety therefore food safety socialization to the low educated and midle-low income housewife is needed.

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.
