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: 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: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
