Judul: The Influence of Entrepreneurial Characteristics on the Business Success of Beef Cattle Farmers in Blora Regency
Abstrak: Kabupaten Blora terkenal sebagai sentra sapi potong di Jawa Tengah dan tidak pernah mengalami penurunan produksi dalam sepuluh tahun terakhir. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik kewirausahaan terhadap keberhasilan usaha. Pengumpulan data dilakukan dengan wawancara dan pengisian kuesioner dengan menggunakan dua teknik sampling, yaitu cluster sampling dan purposive sampling. Jumlah sampel pada penelitian ini sebanyak 100 responden dan data dianalisis dengan Structural Equational Modeling Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa masing-masing variabel karakteristik kewirausahaan yang terdiri dari percaya diri, bekerja keras, berorientasi masa depan, inovatif, berani mengambil risiko, dan tanggung jawab tergolong baik. Variabel keberhasilan usaha mampu dijelaskan 87,6 persen oleh masing-masing variabel karateristik kewirausahaan dengan nilai R-square sebesar 0,876. Karakteristik kewirausahaan yang berpengaruh signifikan terhadap keberhasilan usaha diantaranya bekerja keras, berorientasi masa depan, inovatif, dan tanggung jawab. Sedangkan percaya diri dan berani mengambil risiko berpengaruh tidak signifikan terhadap keberhasilan usaha., Blora Regency is known as a center for beef cattle in Central Java and has never experienced a decline in production in the last ten years. This research aims to analize the influence of entrepreneurial; characteristics on business success. Data collection was carried out by interviews and filling out questionnaires using two sampling, namely cluster sampling and purposive sampling. The number of samples in this research was 100 respondens and the data was analyzed using Structural Equational Modeling Partial Least Square (SEM-PLS). The result of the research show that each variable of entrepreneurial characteristic consisting of self-confidence, working hard, future-oriented, innovative, daring to take risks, and responsibility is classified as good. The business success variable can be explained 87,6 percent by each entrepreneurial characteristic variable with an R-square value 0,876. Entrepreneurial characteristic that have a significant influence on business success include hard work, future oriented, innovation, and responsibility. Meanwhile, self-confidence and the courage to take risks do not have a significant effect on business success.

Judul: The Entrepreneur Characteristics, Entrepreneurial Competencies and Business Performance of The Dairy Farm in Kania Dairy Farmer Group Bogor
Abstrak: The entrepreneurship has a very strong positive relationship with economic growth in which an increasing number of entrepreneurs led to an increase in economic growth of a country. In its role in the economic growth, the entrepreneurship activities absorb local resources and create jobs. The livestock sub-sector is one part of the agricultural sector has developed various types of business and labor-intensive, one of which is dairy farm business. The dairy farm business has a good chance to develop because of the market demand for milk is still large and about 74 percent of the milk demand in Indonesia supplied by imported milk. The West Java Province is a province that has the third largest population of dairy cows in Indonesia that increased from 2008 through 2012. The Bogor Regency is one of the areas in the West Java Province that has a lot of dairy cow population. Dairy cow is also designated as one of 17 leading commodities by the Government of Bogor Regency. The dairy farms in Tajurhalang Village, Cijeruk District is one of areas of dairy farm which is located in Bogor Regency. The dairy farmers in Tajurhalang Village incorporated in Kania Dairy Farmer Group. The dairy farmers in Kania Dairy Farmer Group have skills in cultivating the dairy cow and processing the dairy products, but these skills have not been optimally utilized to develop the potential opportunities that exist. If it is utilized properly, it can improve the business performance of dairy farmers. The performance appraisal is one way to measure the success of a business. The performance related to skills, abilities and individual traits. Therefore, the research on the entrepreneur characteristics, entrepreneurial competencies and business performance needs to be conducted. This study aims to (1) analyze the entrepreneur characteristics, entrepreneurial competencies and business performance of the dairy farmers, (2) analyze the relationship of entrepreneur characteristics and entrepreneurial competencies with business performance of the dairy farmers, (3) analyze the relationship between the entrepreneur characteristics and entrepreneurial competencies together with business performance of the dairy farmers. The research objectives used descriptive qualitative analysis and quantitative analysis with correlation Kendall Tau (τ) test and Kendall W test. The respondents were 39 dairy farmers, determined using the census method, which the respondents are all active members of Kania Dairy Farmer Group who produce milk. The quantitative data in this study were processed using SPSS ( Statistical Package for the Social Sciences). In this study, the measured variable is divided into three sections, i.e the entrepreneur characteristics variable with 18 indicators, the entrepreneurial competencies variable with 18 indicators and the business performance variable with three indicators . The results showed that (1) the level of entrepreneur characteristics, entrepreneurial competencies and business performance of the dairy farmers are at a low level, (2) the entrepreneur characteristic has an adequate real positive significant relationship with entrepreneurial competencies of the dairy farmers. The entrepreneur characteristics and entrepreneurial competencies each with business performance has no real positive relationship, (3) the entrepreneur characteristics and entrepreneurial competencies together with business performance of the dairy farmers have a real

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.
