Judul: Kajian sektor perekonomian unggulan di Provinsi Lampung
Abstrak: Local governments are given the authority to manage all resources to achieve development goals, namely economic growth and income distribution. Insufficient resources require development planning priorities. An appropriate regional development must be supported by leading sector development, therefore the local government needs to discover the leading economic sectors ofits region. The method used in this research is the analysis of input-output tables of Lampung Province in 2010 by 53 sectors which is aggregated into nine sectors. The analysis includes linkage analysis, dispersion effect and multiplier effects. The leading sectors in the Lampung Province based on input-output analysis, namely the manufacturing sector with industry specification of wood and products of wood and cork and wickerwork from bamboo, rattan and similar products as well as the furniture industry; transportation and communications sector with a specification of transport via railways, sea and coastal water transport, and inland water transport and crossing; and the construction sector with a specification of civil engineering, specialized construction activities, and building construction. Other sectors based on analysis of 53 sectors that become leading sectors are activities auxiliary to financial services sector and water supply.

Judul: The roles of agroindustry in the regional economy of Lampung Province: analysis of intersectoral linkages and agglomeration of industries
Abstrak: The objectives of this study are to analyze intersectoral linkages among agroindustry in the regional economy of Lampung Province, to identify the existence of spatial concentration and agglomeration of agroindustry, to analyze agglomeration economies in the agroindustrial sectors, and to analyze some policies that are potentially improve the roles of agroindustry in the regional economy. This study used data of provincial Input-Output Table of 2000 and 2005 aggregated into 26 sectors (12 agroindustrial sectors and 14 non agroindustrial sectors) and results of Medium and Large Industrial Survey 1998-2005. In addition, it used indices to measure the size of agglomeration. It utilized also Cobb-Douglas production function to measure the agglomeration economies. Some policy simulations were analyzed to identify the effects of changes of final demand on sectoral outputs, income, and labor. The results show that in terms of linkages and multipliers of sectoral output, income, and labor, agroindustrial sectors have the biggest roles in the regional economy. The sectors also boost the other sectors’ growth. They have strong backward as well as forward linkages that are greater than those of other sectors. Most agroindustrial sectors are concentrated in one or few districts/municipalities. These concentrations significantly effect the production outputs. Most economies of localization and urbanization exist in the agroindustrial sectors. The combined policies of increasing government expenditure, investment, and export that are proportionally allocated to all of the agglomerated agroindustrial sectors result in the greatest positive change of sectoral output, households’ income, and labors absorption. The impact of economic policy on the agglomerated agroindustrial sectors are greater than that of similar policy that are applied to non agglomerated agroindustrial sectors.

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.
