Judul: Analisis komoditas unggulan dan tingkat partisipasi petani dalam pengembangan pertanian Kabupaten Bulukumba
Abstrak: Agriculture is an important sector in the economic system and also a basic sector mainly in South Sulawesi province and Bulukumba regency. As one of the provinces in the eastern Indonesia that acts as a national food barn, therefore since 1988, the provincial government had been implemented the commodity region concepts in order to optimaze the resources utilization based on the characteristics of each region. Bulukumba regency is one of the regions that possess not only various geographic area such as highlands and lowlands but also act as the basic capital in developing many kinds of agricultural commodities. Therefore, the determination of prime commodities was importantly needed in developing this region to be more targeted and more focused so that it would be increased the local communities and region incomes. Participation level of farmers was also extremely expected in developing our prime commodities because farmers become one of the main actors in determining the yield of agricultural production. In the future, agricultural sector will be redirected into agro-industrial sector as an integration form with industrial sector. This research was generally aimed to develop the strategies for developing the sector and prime commodities and also other derivative sectors whereas on the other hand. This research was also specifically aimed to (1) identify the prime agricultural subsectors of Bulukumba regency mainly in South Sulawesi province, (2) identify the prime commodities in Bulukumba regency based on the comparative and competitive advantage and opinion from government apparatus and (3) analyze the participation level of farmers in the development of prime commodities. The analysis methods employed in this study were prime subsector and prime commodities analysis, analytical hierarchy process (AHP) and participation level of farmers analysis. Prime subsector and prime commodities analysis were conducted using location quotient (LQ) analysis that acts as a comparative advantage and differential shift (DS) that acts as a competitive advantage. In this research, LQ analysis was performed using the data in the year of 2010 while DS analysis was performed using the data in the year of 2006 and 2010. AHP is a method for decision-making in order to determine the prime commodities based on the view of official government. The AHP’s criteria used in this study are: (1) natural resources, (2) farmers' preferences, (3) public policy, (4) economic contribution, (5) institutional and (6) market. Participation level of farmer analysis was performed using cross-tabulation in order to observe the relationship between inter-variables such as willingness, ability and farmers’ opportunity in participating for the development of prime commodities. Prime subsectors in Bulukumba regency are food crops, plantation crops and livestock subsectors while fisheries and forestry subsectors were only strategic in term of competitive advantage but not comparative advantage. The results showed that our agriculture sector in Bulukumba regency was a basic sector and dominant prime subsector both in term of comparative and competitive advantage so that this sector was very potential to be developed. The prime vii agricultural commodities both in term of comparative and competitive advantage in Bulukumba regency were consist of 20 commodities from all three subsectors of eminent and always

Judul: An analysis of prime agricultural comodities and their development strategy In Ciamis Regency, West Java Province;
Abstrak: The regional development in the regional autonomy era requires development of regional potential inside the region itself (local development) which is prioritized to the commodities development. The aims of the study is to analyze the prime agriculture commodities and how to formulate their development strategy. The research was conducted in Ciamis Regency, west Java Province March to July 2011. The analysed data is input-output table of Ciamis regency year 2008. To determine prime agriculture commodities analyze with backward and forward linkage, backward and forward dispersion as well as output, income and employment multiplier. The development strategy was formulated using combination of two analyse; those are the AHP and SWOT analyse (A-WOT). The results show that the prime agriculture commodities in Ciamis regency are rice product with index composite value around 0.75, chicken meat product with index composite value around 0.68 and cow with index composite value 0.67. Development strategies for the three prime agriculture commodities are as follow: increasing quantity and quality rice production; capital assistance for local economic actors (poultry shop and breeding farm); increasing cow population through revolving fund and insemination program.

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.
