Judul: Strategies of developing sources of regional income in Lampung Barat district
Abstrak: Lampung Barat District encounters a limited capability of increasing its own income due to (a) regulations of the central government to avoid high cost economy facing business activities, (b) its region with a large proportion of forest area, and (c) agricultural sector dominating its regional domestic product. As a result, strategies of developing sources of its local incomes are badly needed. This study is aimed (1) to identify the development of its income based on sources by comparing pre and post of autonomy periods, (2) to analyse sources of its regional income, (c) to regress factors affecting its regional income and (4) to recommend strategies and programmes to increase its regional income. To answer those objectives, ARIMA and linear regression models were developed as well as a logical framework approach. Variables identified to possibly affect the local government incomes are its per capita income, inflation rate and government expenditure. Other sources of government income are also incorporated into model, that are a number of hotel guests, a number of restaurants and a number of shops and kiosks. Results prove that per capita income and government expenditure affect significantly the local government income. Amongst sources of potential incomes, only a number of shops and kiosks are identified to increase the government income. Recommended programmes to increase the government income are (a) identification of sources of potential income either from tax or retribution, (b) socialisation of the importance of tax and retribution to the economic development in the region, (c) an increase in investment in public sectors and (d) improvement of regional state-owned-companies and (e) regulations of improving business environment in the region.

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: 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.
