Judul: Analysis of agricultural extension institutions in the province of Riau
Abstrak: Sejak diberlakukannya Undang-undang Republik Indonesia No. 22 tahun 1999 yang diamandemen dengan UU No. 32 tahun 2004 tentang Pemerintahan Daerah, Undang-Undang nomor 16 tahun 2006 tentang Sistem Penyuluhan Pertanian dan Peraturuan Pemerintah No 41 tahun 2007 tentang Kelembagaan Daerah, telah mewarnai penyelenggaraan penyuluhan pertanian. Penafsiran yang berbeda-beda terhadap kebijakan publik tersebut, telah merubah pranata dan struktur kelembagaan penyuluhan pertanian serta operasionalisasinya di daerah. Keragaman kelembagaan yang menangani penyelenggaraan penyuluhan pertanian mengakibatkan beragamnya kinerja penyuluhan tersebut, dan konsekuensinya berpengaruh terhadap sasaran utama pembangunan pertanian yaitu para petani. Penyelenggaraan penyuluhan pertanian akan berjalan dengan baik apabila ada persamaan persepsi dan keterpaduan kegiatan antara pemerintah pusat, provinsi dan kabupaten/kota bahkan sampai ke tingkat desa dalam satu system penyuluhan pertanian yang disepakati bersama dengan melibatkan petani, swasta dan pihakpihak yang berkepentingan. Dalam kenyataannya sekarang, masing-masing instansi berjalan sendiri-sendiri, sehingga penyelenggaraan penyuluhan pertanian menjadi tidak produktif, tidak efektif dan efisien., This era of regional autonomy with its emphasis on the efficiency of institutions and improved human resources has made some changes in the extension paradigm. Different regions have different responses. Some still maintain their extension institutions as they were in the past while others have changed the extension system. The varied institutions that are responsible for agricultural extension have certainly resulted in different performance, and consequently affected the main target of agricultural development, namely farmers.

Judul: Analysis of Agricultural Extension Institutions in the Province of Riau
Abstrak: This era of regional autonomy with its emphasis on the efficiency of institutions and improved human resources has made some changes in the extension paradigm. Different regions have different responses. Some still maintain their extension institutions as they were in the past while others have changed the extension system. The varied institutions that are responsible for agricultural extension have certainly resulted in different performance, and consequently affected the main target of agricultural development, namely farmers. This study was intended to: (1) identify the structure of agricultural extension institutions in the regional autonomy era in the Province of Riau, (2) analyze the implementation of agricultural extensions in different institutions, and (3) analyze the effect of different extension implementation on the performance of extension workers and the degree of technological application among farmers. This is a descriptive study through a survey conducted from March to April 2008 in three regencies/towns, namely Pekanbaru, Kampar Regency and Pelalawan Regency.

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.
