Judul: Performance Communication of Farmers’ Association Recipients of Rural Agribusiness Development Program (Case at Siak Kecil Subdistrict Bengkalis District Riau).
Abstrak: focuses in reducing poverty and also creating a huge accupation in rural area by providing venture capital to support on farm and off farm activities. Farmers’ association (Gapoktan) as an implementer of PUAP has a pivotal function to distribute incentives, venture capital, and also as the managers of all the programs given. From that perspective Gapoktan holds an important role for the success full of this program. Communication process among group members in Gapoktan and interpersonal communication between change agents and the Gapoktan needs to be inquired because it was estimated as one of the important factor that influencing PUAP program. The objectives of this research were: (1) to describe the performance communication of Gapoktan, (2) to describe the characteristic, role and ability of Gapoktan, (3) to analysis the correlation between all variables. This research resulted several important usults, namely: The communication of Gapoktan was good and the communication change agents were not enough until less than not enough. The characteristics were categorized good, role and the ability were not enough, there were a significant correlation between the characteristics with the communication of Gapoktan, between the communication of change agents with the role of Gapoktan and between role with ability of farmers’ association (Gapoktan).

Judul: Efektivitas Komunikasi Pada Program Pengembangan Usaha Agribisnis Perdesaan (PUAP) Di Kabupaten Halmahera Barat
Abstrak: Rural Agribusiness Development Program (PUAP) is a program of Ministry Agriculture of Republic Indonesian (RI) toward poor farmers in the village. The objectives of this research were; (1) to analyze the level of PUAP program communication effectiveness, (2) to analyze relationship between the characteristics of Gapoktan members and perception about PUAP program, (3) to analyze relationship between Gapoktan members and communication effectiveness on PUAP program, (4) to analyze relationsip between the perception of Gapoktan members and communication affectivity on PUAP program and (5) to analyze relationship between communication of Gapoktan members behaviour and communication effectiveness on PUAP program. This Research was designed as correlation descriptive. Seventy one farmers were taking as sample by proportional cluster random sampling from Gapoktan members who received PUAP donation support in 2009, in two subdistricts in the West Halmahera. Data were analyzed used rank spearman correlation. Result of research showed that (1) communication PUAP Program in West Halmahera district has lasted effectively, it is shown by the knowledge and actions of the Gapoktan members is still relatively moderate, especially about the making of the work plan, utilization and refund PUAP program, whereas group union member attitudes toward the implementation of PUAP is relatively high, (2) characteristics of Gapoktan members significantly correlated with their perceptions on PUAP Program, (3) characteristics of members Gapoktan not significantly correlated with the effectiveness of communication in PUAP Program, (4) perceptions of members Gapoktan of the Program PUAP significantly correlated with the effectiveness of communication in PUAP Program, and (5) Gapoktan member communication behaviours significantly correlated with the effectiveness of communication in PUAP Program.

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.
