Judul: Analisis spasial disparitas pembangunan antar wilayah di provinsi Sumatera Barat
Abstrak: The phenomenon of disparity areas have become commonplace in the development of an area for various reasons. Development of region in the province of West Sumatra by naked eye there is a disparity in the region indicated. The objectives of this research are 1) determine the amount of disparity in development between regions, 2) identify the sectors held by each district / city; 3) determine the level of development and regional characteristics; 4) analyze the factors that cause disparities in development among regions; 5) to formulate strategies to address the problem of regional development disparities. Analytical methods used are Williamsons Index, Theill Index, Location Quotient Index, Shift Share Analysis, Scalogram Method, Entropy Index, Physical Analysis, Klassen Typology, Factor Analysis, Multiple Regression, and SWOT analysis. The analysis showed there are gaps in the province of West Sumatra which occurs predominantly among areas within the territory of the border region. Dominant sector in the district are agriculture, while in urban areas is service sector. The main factor that caused the region is an indicator of economic inequality and population indicators. The strategies that can be used to overcome the inequality are in development of other sectors of the economy of the agricultural sector and the optimization of the center point of growth and service center region.

Judul: Evaluation of Influenza Antibody Titers in Serum and Egg Yolk of Layers Vaccinated with Influenza Vaccines.
Abstrak: Influenza belongs to the Orthomyxoviridae family which causes upper and lower respiratory tract infection. The aim of this study was to evaluate influenza-A specific antibody titers from serum and egg yolk of hens vaccinated with quadrivalent influenza vaccines. Three Hy-line Brown layers were vaccinated with quadrivalent influenza type A and B inactivated vaccines. Vaccination was carried out three times at a dose of 0.25 ml/chicken via the intramuscular route. The first vaccination was carried out at 24 weeks of age, then boosters were performed at 28 and 32 weeks of age. Serum and egg yolk were collected every week for 20 weeks since the first vaccination. Influenza A H3N2 and H1N1 antibody titers were determined using hemagglutination-inhibition (HI) test and agar-gel-precipitation (AGP) test. Influenza-A H3N2 and H1N1 specific antibodies were detected in both serum and egg yolk from the first to twenty weeks after the initial vaccination. Highest HI geometric mean titer (GMT) of H1N1 antibody reached 26.67 HIU at nine weeks post first vaccination (p.f.v), while H3N2 antibody reached 26 HIU at six weeks p.f.v. Our result showed that influenza antibodies can be produced in layers using quadrivalent vaccines and layer chickens are able to produce equivalent antibody levels for each influenza subtype.
