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.

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. The data collected for the study consist of primary and secondary data. The primary data were obtained from a structured interview by using questionnaires and a focus group discussion. The secondary data were collected by examining documents or reports from the related institutions. To determine alternative strategies in developing the extension institutions in the Province of Riau, an analysis was made on the internal and external factors, followed with a further analysis of SWOT (strengths, weakness, opportunities, and threat); and to determine the strategy priorities, the study used the method of quantitative strategic planning matrix (QSPM). The study results showed that the implementation of Laws Number 22/1999 and Number 32/2004 along with the regulations under the laws has caused the agricultural extensions in the Province of Riau to experience coevolution in the social infrastructure of agricultural extensions in both regencies/towns and districts. In the implementation, the functions of services and arrangement still dominate the working system of extension. The existence of extension institutions has not been able to accommodate the interests of extension, and the frequency of LAKU is not fully implemented yet. The condition of an extension institution can influence the performance of agricultural extension and give different views on appropriate recommendations in the technology application by farmers. The formulated strategy in developing the agricultural extension institutions in the Province of Riau is to form a separate and specific institution that regulates agricultural extension through the following programs: a) reorganization of the agricultural extension institutions, b) improvement of human resource for agricultural extension, c) improvement in the quality of agricultural extension activities. Therefore, it is urgent to unite extension workers under one institution that can accommodate the interests of agricultural extension workers and farmers as the implementation of Law Number 16/2006.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
