Judul: Analisis Sumberdaya Pangan di Kota Pagaralam Sumatera Selatan Tahun 2001-2010
Abstrak: This study aims to analyze the food resouces in Pagaralam, South of Sumatera in 2001-2010. The study design was retrospective with secondary data of Pagaralam in Figures. Secondary data includes Rencana Pembangunan Jangka Menengah Daerah (RPJMD) Pagaralam, Rencana Strategis (Renstra), food production, exports and imports, budgeting and number of population in Pagaralam City 2001-2010. Data processing covers production analysis, exports and imports, food availability and food suffiency by trend, line, ratio avaibility and ratio of imports analysis. Food availability policy and food avaibility budgeting were analyzed using content analysis. The results indicate increasing of production on some commodities but supply doesn’t fulfill the demand. Food avaibility is increased and energy suffiency has already reached the SPM (90%), but protein suffiency hasn’t reached the SPM. Desirable Dietary Pattern (DDP) score is still below 90. The food avaibility policy and budget are not support the Kebijakan Umum Ketahanan Pangan (KUKP) 2006-2010 and still focused on water resource management.

Judul: Analisis perencanaan penyediaan pangan berdasarkan pola pangan harapan (PPH) Kabupaten Sinjai Provinsi Sulawesi Selatan
Abstrak: Food security constitutes substance which is important and connected tightly with social security, economic stability, politic stability and nation security. The Act of the Republic of Indonesia Number 7/1996 on food stated that food is fundamental requirement in the availability of sufficient food both its in quantity and quality, including safety to the prosperity and welfare of Indonesian. As otonom's region government has authority to manage food security developments, PP No 38/2007 commanding food securitys as mandatory of goverment. This research was aimed to analyze food availability planning in Regency Sinjai, based on: 1) availability of calory (2,200 kcal) and protein (57 gram) per capita per day, and (2) consumption adequacy per capita per day of calory (2,000 kcal) and protein (52 gram), indicated by a DDP score of 100 in 2020. This research was carried out in Sinjai Regency in South Sulawesi Province in November to December 2010. The research design was retrospective utilyzing secondary data from institution related to food security. The result showed that availability of energy and protein in 2007-2008 were increased. The average of food availability was 2,923 kcal that was higher than standard (2,200 kcal/day), a slightly different picture was shown in the average availability of protein was 92.6 gram that was higher than standard (52 g/day). Meanwhile availibility of protein was dominated by plant food. On an average the availability was above the national standard (WNPG VIII, 2004). The average of calory consumption of food group in the total consumption was 2,394 kcal (slightly above of the standard), with DDP consumption in 2008 was 90.3. The basis Projection of quality food availability and food consumption in 2011 to 2020 are balance diet that is indicated by a DDP score of 100 in 2020. Land potential of Sinjai Regency for Wetlands is 13.561 ha in 2008, while wetland needs of rice production sustainability is 14.454 ha in 2020. The regulation of Sinjai regency was estabilished that agricultural farm and fishery farm for sustainability was 40,637 ha.

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.
