Judul: Pengaruh Karakteristik Personal Peternak Terhadap Intensitas Adopsi Saptausaha Ayam Buras
Abstrak: Penelitian ini dilakukan di Desa Kadumanggu Kecamatan Citeureup Kabupaten Bogor selama dua bulan yaitu pada bulan Nopember dan Desember 1989. Tujuan penelitian adalah untuk mengetahui karakteristik personal peternak di Desa Kadumanggu Kecamatan Citeureup Kabupaten Bogor, mengetahui sampai sejauh mana peternak menguasai materi penyuluhan dan menerapkannya pada perternakan mereka, dan untuk mengetahui keterkaitan antara karakteristik personal petemak dengan intensitas adopsi Saptausaha Ayam Buras. Karakteristik personal yang diamati meliputi; umur, tingkat pendidikan, kekosmopolitan, dan kontak dengan penyuluh, sedangkan Saptausaha Ayam Buras yang diamati meliputi bibit, makanan ternak, reproduksi, perkandangan, dan pencegahan serta pengobat an penyakit. Populasi penelitian adalah seluruh peserta proyek pembinaan kelompok petani ternak ayam buras yang berjumlah 115 kepala keluarga dan sampel diambil 40 kepala keluarga secara acak. Metoda penelitian yang digunakan adalah metoda survey yang bersifat "participatory observation" (pengamatan partisipatif) dan untuk pengumpulan data serta pengamatan digunakan kuesioner. Data yang diperoleh di olah menggunakan prosedur frekuensi distribusi, dan statistika deskriptif. Pengujian hubungan antara karak teristik personal peternak dengan intensitas adopsi Sapta usaha Ayam Buras digunakan uji Khi-Kwadrat. Hipotesis penelitian adalah terdapat keterkaitan antara variasi karakteristik personal dengan variasi intensitas adopsi Saptausaha Ayam Buras. ...

Judul: Perilaku wirausaha wanita peternak dalam mencari dan menerapkan informasi usaha ternak ayam buras
Abstrak: The aims of this research are : to identify the characteristics of the women of poultry farmers, to analyse the women of poultry farmers entrepreneur behaviour to find and apply the poultry business information and analyse the relationship between the women of poultry farmers internal and external characteristics to the entrepreneur behaviour in finding and applying the poultry business information. This research was carried out a month, from April to May 2006 in Taman Sari Village, Subdistrict of Taman Sari, Bogor District. The research population are all of the women of poultry farmers who join in Tanjung group and the method for choosing the samples was using sensus. The data consist of primary and secondary data. Data analyses was using descriptive analysis and rank Spearman and Chi Sqztare correlation test. The results show that : The number of family members has significant relationship to the entrepreneur attitude and has very significant relationship to the entrepreneur skill, and the business motivation has significant relationship to the entrepreneur attitude. The interaction between extension educator agent and the women of poultry farmers have significant relationship to the entrepreneur attitude and entrepreneur skill, and the interaction between peddler and women of poultry farmers has significant relationship to the entrepreneur skill. Keywords: Internal characteristics, external characteristics, entrepreneur behaviour.

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.
