Judul: Hubungan karakteristik wirausaha dengan kinerja industri Tempe di Kabupaten Bogor
Abstrak: Micro and small industries have increased in business performance relatively faster compared to medium and large industries. However, not all micro and small industries increased business performance, such as tempeh industry experience performance degradation due to still face obstacles in running their business. Therefore, it is necessary to identify whether the performance of industrial enterprises decreased due to tempeh entrepreneurs have low entrepreneurial characteristics. Characteristics of entrepreneurs allegedly associated with strong and positive business performance. The purpose of this study to measure the characteristics of an entrepreneurial relationship with business performance tempeh industry. Entrepreneurial characteristics used in this study include self-confidence, result oriented, risk taker, leadership, originality and future-oriented. Tempeh industry business performance measured include production, turnover and profit. Analyzer used Spearman Rank correlation. The results showed a positive correlation between results-oriented and originality to the production and turnover, while there is a positive correlation between entrepreneurial characteristics, except confidence and leadership with a profit.

Judul: Hubungan karakteristik wirausaha dengan kinerja usaha peserta program mahasiswa wirausaha Institut Pertanian Bogor
Abstrak: Program Mahasiswa Wirausaha merupakan salah satu program kewirausahaan untuk mengurangi pengangguran lulusan perguruan tinggi. Institut Pertanian Bogor adalah salah satu perguruan tinggi yang mengembangkan program ini. Namun, banyak peserta yang tidak mampu mempertahankan keberlanjutan usahanya. Keberlanjutan usaha ini dapat menggambarkan pencapaian kinerja usaha yang dijalankan. Salah satu faktor yang diduga memengaruhi kinerja usaha peserta adalah karakteristik wirausaha. Tujuan penelitian ini adalah untuk mengidentifikasi karakteristik wirausaha yang dimiliki para peserta dan menganalisis hubungan karakteristik wirausaha dengan kinerja usaha. Karakteristik wirausaha yang digunakan dalam penelitian ini meliputi percaya diri, orientasi hasil, pengambil risiko, kepemimpinan, keorisinilian, dan orientasi masa depan. Kinerja usaha yang diukur meliputi omzet dan pertumbuhan usaha. Alat analisis yang digunakan adalah korelasi Rank Spearman. Hasil penelitian menunjukkan peserta memiliki karakteristik wirausaha yang tinggi dan terdapat korelasi positif antara percaya diri, kepemimpinan, keorisinilan dan orientasi masa depan dengan omzet dan pertumbuhan usaha. Sementara, orientasi hasil dan pengambil risiko hanya berkorelasi positif dengan omzet….

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.
