Judul: Analisis Keterkaitan Antar Sektor Ekonomi di Provinsi Aceh : Pendekatan Input-Output
Abstrak: The economic sectors have a crucial role in the development of both national and regional economy. A comprehensive and sustainable economic integration among all production sectors is the key to a successful economic development. In a market economy, an integrated economy can be seen when interaction occur among the economic players-buying and selling the input and output of production. The objectives of this research were to (1) analyze the contribution of economic sectors in the development of Aceh province, (2) analyze the linkage among the economic sectors in the development of Aceh province, (3) analyze the impact (multiplier) of changes in the final demand on output, income and labor in the economic sectors, and (4) analyze the impact of changes in the consumption expenditure of the household, government, and export on output, income and labor economic sectors. Input-output tables were used to analyze the magnitude of linkages among the sectors in the economic development of a region. The results showed that the gas mining sector in the economic sector with a relatively large role in the creation of output and added values in the economic development of Aceh province. In terms of the linkage level, the sector with the greatest value of direct backward linkage is the electricity sector, while the sector with the largest value of direct and indirect backward linkages are the industrial sectors of food, beverages and tobacco. Meanwhile, the sector with the biggest value of forward linkage is the trade sector, whereas the gas mining sector has the biggest value of direct and indirect forward linkage. Based on the output multiplier value, the output of food, beverages and tobacco industrial sectors have a relativey large value compared with the other economic sectors. As for the value of income multiplier, electricity sectors as well as industrial sectors of food, beverages and tobacco have relatively high multiplier values. In terms of the labor multiplier, the sector with a relatively high multiplier value is the milling industry of rice, grain and flour. Meanwhile, result simulation the scenario of first showed that increasing the number of output whole the economic sector has a relatively large compared with increase of income and labor. The result simulation the scenario of second showed that decrease consumption of the household and government there caused to decrease the number of output and labor in whole economic sector. While result simulation the scenario of third showed that if the export was raised, increasing the number of output is relatively larger than increase of income and labor. Of the three of simulations to increase the number of output be the third scenario is capable to producing the greatest number of output in whole economic sector.

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.
