Judul: Pembangunan Sektoral dan Regional Dalam Mendorong Pertumbuhan Ekonomi dan Pengentasan Kemiskinan di Kepulauan Riau
Abstrak: Pembangunan ekonomi dilakukan untuk menciptakan kesejahteraan masyarakat melalui pertumbuhan ekonomi yang stabil serta pengurangan tingkat kemiskinan. Provinsi Kepulauan Riau, meskipun dalam lima tahun terakhir masih termasuk dalam provinsi dengan tingkat pendapatan perkapita yang relatif tinggi namun pertumbuhan ekonominya mengalami perlambanan serta terjadi ketimpangan antar wilayah baik dari sisi pertumbuhan ekonomi maupun tingkat kemiskinan. Pengembangan ekonomi sektoral dan regional dapat mendorong pertumbuhan ekonomi berkelanjutan serta pengentasan kemiskinan melalui redistribusi pendapatan. Dengan demikian tujuan utama penelitian ini adalah menganalisis sektor unggulan dan wilayah pengembangan sektor unggulan serta menganalisis dampak sektor unggulan tersebut terhadap pertumbuhan ekonomi dan kemiskinan di Provinsi Kepulauan Riau. Hasil analisis Tipologi Klassen yang didasarkan pada nilai LQ (Location Quotient) dan DS (Differential Shift) menunjukan bahwa 3 sektor unggulan tertinggi di Provinsi Kepulauan Riau ialah sektor pertambangan dan penggalian, sektor konstruksi, dan sektor industri pengolahan. Namun demikian, hasil analisis ekonometrik data panel menunjukan bahwa hanya dua sektor unggulan yang mampu secara signifikan mendorong pertumbuhan ekonomi dan sekaligus menurunkan kemiskinan yaitu sektor pertambangan dan penggalian serta sektor konstruksi. Untuk dapat mengembangkan kedua sektor unggulan tersebut secara optimal, secara regional berdasarkan analisis Tipologi Klassen, wilayah pengembangannya adalah Kepulauan Anambas dan Natuna untuk sektor pertambangan dan penggalian; sementara untuk sektor konstruksi, wilayah pengembangannya adalah Batam., Economic development is carried out to create community welfare through stable economic growth and poverty reduction. Riau Archipelago Province, although in the last five years it is still included in the province with a relatively high level of per capita income, its economic growth has slowed and there have been disparities between regions both in terms of economic growth and poverty levels. Sectoral and regional economic development can promote sustainable economic growth and poverty alleviation through income redistribution. Thus, the main objective of this study is to analyze the leading sectors and areas of development of the leading sectors and to analyze the impact of these leading sectors on economic growth and poverty in the Riau Islands Province. The results of the Klassen Typology analysis based on the LQ (Location Quotient) and DS (Differential Shift) values show that the 3 highest leading sectors in the Riau Islands Province are the mining and quarrying sector, the construction sector, and the manufacturing industry sector. However, the results of the econometric analysis of panel data show that only two leading sectors are able to significantly boost economic growth and at the same time reduce poverty, namely the mining and quarrying sector and the construction sector. In order to develop the two leading sectors optimally, regionally based on Klassen's Typology analysis, the development areas are the Anambas and Natuna Islands for the mining and quarrying sector; while for the construction sector, the development area is Batam.

Judul: Kajian disparitas pembangunan antar wilayah di Provinsi Kepulauan Riau
Abstrak: Province of Riau Islands, a region as a result of the division of the Province of Riau, has high disparity between Batam and other districts. The objectives of the study are: (1) to identify priority sectors in each district; (2) to analyze level of development in each district; (3) to analyze condition and magnitude of disparity in the Province of Riau Islands; and (4) to analyze the regional development strategies of Province of Riau Islands. The analytical method used are Locational Quotient Analysis (LQ), Shift Share Analysis (SSA), Scalogram Analysis, Williamson Index, Theil Index, and Analytical Hierarchy Process (AHP). The result showed industry and commerce have become the first priority sector in urban areas. In the other hand, agricultural sector, particularly fishery, is the dominant sector in rural areas. The result of Scalogram Analysis showed the urban areas are in the first hierarchy, while the rural areas are in the second and third hierarchy. In the period of 2006 to 2010, the disparity level was decrease as indicated by 0.85 of Williamson Index (high disparity) in 2006 to 0.49 (average disparity) in 2010. The result of AHP showed the policy of regional development was to increase development of the regional infrastructure emphasize to fishery and marine sector, because the fishery and marine sector in Province of Riau Islands have a great potential.

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.
