Judul: Hubungan antara karakteristik dan keaktifan komunikasi dengan perilaku agribisnis (studi kasus peternak ayam broiler di Kecamatan Leuwiliang, Kabupaten Bogor )
Abstrak: The aim of this research was to know the relationship between characteristic of chicken broiler farmer at Leuwiliang and their activity rate of searching information with agribusiness oriented behavior. The research conducted on September 29" - October 29" 2005 in Leuwiliang Sub district, Bogor Regency West Java. Attitude aspect of agribusiness oriented behavior is in high rate, knowledge aspect in a medium rate, and the action aspect also in a medium rate. Chi square test with significant at 0.05 tells that there are high relationship between characteristic of farmer with agribusiness oriented behavior, especially with ages, experiences, and scale of husbandry. There is relationship between agribuiiiess oriented behavior with broiler farmer communication activity, especially when they do communication with the extension officer. The indirect information source which have high relationship are radio. Keywords: Broiler farmer, agribusiness, behavior

Judul: Faktor-faktor yang berhubungan dengan aktivitas komunikasi denan aktivitas komunikasi anggota kelompok peternak (studi kasus kelompok peternak sapi perah di Kelurahan Kebon Pedes, Kota Bogor )
Abstrak: Effectivity of group as an influence activity communication in the group. The aims of this research are (1) to identified the factors that associated with activity communication (2) to study activity communication, (3) to know the connection betweem intend factors, dairy farm factors, group factm and an environment factors with activity communication This research was conducted on April 2006 at Vdlage Kebon Pedes, Bogor.The research populations are 28 breeder dairy cattle in 'Terpencar" group. Method was using sensus with correlational descriptif method to descript connection factors with activity communication Data analyzes with SPSS 11.5 program for windows with Rank Spearman, Tub- Kendall and Chi-Square correlations test The result show that form education that correlated with interpersonal communication and participation at strong correlated. Norm that correlated with interpersonal communication at low correlated. Group aims that correlated with medium communication at low correlated. Subsidy government that correlated with participation at strong enough correlated. Policy government that correlated with medium communication at low correlated.

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
