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: Analysis of regional development and disparities in regional development border and non-border in West Kalimantan
Abstrak: Indonesia is an archipelago that has many border areas with other countries in the region of sea and land. In West Kalimantan border there are 5 district border, namely are Sambas District, Bengkayang, Sanggau, Sintang, and Kapuas Hulu District. The border region of a country has a strategic value in supporting the success of national development, especially in the aspect of political, economic, and ecological. Border areas of natural resource potential is quite large and very high economic value, yet can be put to good use. The research was conducted in 5 districts in West Kalimantan border and aims to determine the level of development of regions, Leading sectors, the level of disparity that occurred in the border regions and the factors causing the disparity, further research will be able to provide recommendations in the process of border regional development policy. Analytical methods used to achieve these objectives include skalogram analysis, analysis of LQ and SSA, Williamson index and Theil Entropy Index, and Spatial Econometrics. The results obtained by the analysis that the level of development of border districts in the county is still dominated by 3 hierarchy and 2 hierarchy, which means that the facilities and infrastructure in almost all sub-district boundary is uneven and inadequate, both non-border districts and district boundaries. Leading sectors in the three border districts of Sambas District, Sanggau, and Kapuas Hulu District is the agricultural sector, but it is trade, hotels, and restaurants, transport and communication sector, financial sector, rental and service companies, as well as the service sector. The mining sector is a sector that has the potential to be developed in some districts such as districts Paloh in Sambas district, and some non-border districts in the District and other Kapuas Hulu. Disparity analysis results showed that there was disparity sub districts in the border counties with Williamson index value of 0.54. Disparities that occur in the form of disparities within each group the Border District Area (WKP) and the Non-Border District Area groups (WKNP). The factors that cause disparities in the border region is a factor of its own sub-regional GDP (GDP), and the surrounding district GRDP (W_PDRB), as well as factors that occur in the sub-district disparities around (W_Disparitas). Disparities that occurred in the border districts should be dealt with simultaneously and to put forward a comprehensive approach to prosperity than the approach to safety. Construction of basic infrastructure, especially infrastructure for basic social service needs should be a priority in the district border. Efforts to improve the local economy should be based on resource potential and to create linkages between sectors in one district and inter-sectoral linkages with the surrounding districts.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
