Judul: The impact of agricultural trade liberalization on developed and developing countries economy
Abstrak: The process of economic liberalization that create a free trade area in the world is becoming to be reality after three pillars of agricultural negotiation involved domestic supports, export subsidies, and market access has been agreed to be eliminated by 2013. Nevert heless, this liberalization polic y is believed to be able to create some opportunities and challenges. This policy is expected to change the trade map of all commodities in the world either manufacture or agricultural products. Indonesia is one country that will be expected to be infected by this policy, because agriculture sector is still becoming one of the key sector in Indonesian economy. This research intends: (1) to map the international trade flow specialy in the agricultral sector, (2) to analyze the impact of trade protection elimination, and (3) to explore the impact of tariffs on special product prevailed by Indonesia. The GTAP model was used as the main tool of analysis.

Judul: Competitiveness of the agricultural sector faced with free trade agreement ASEAN-China and its impact on rural economy in Indonesia
Abstrak: This study aimed to: (1) measure the competitiveness of the agricultural sector in supply side, and measure the contribution of various resources to the agricultural output in each of the ASEAN-5 countries and China, such as capital, labor, natural resources and technology; (2) measure export competitiveness of agricultural commodities ASEAN-5 and China in global market (3) measure the transmission of international prices of agricultural commodities to the domestic market in each countries, (4) analyze the impact of trade liberalization under ACFTA agreement framework to the macroeconomic of each country of ASEAN-5 and China as well as its impact on the rural economy in Indonesia and (5) analyze the impact of improved agricultural technologies, and transmission of international prices on the economy national and rural economy in Indonesia. Competitiveness of the supply side is analyzed based on the total factor productivity (TFP), while in the global market competitiveness based on revealed comparative adventage (RCA), index of market share, trade specialization index (ISP) and trade complementary index (IKP). Price transmission were analyzed by Revallion model, while the impact of ACFTA to each country's economy and the implications for rural economy in Indonesia were analyzed by static CGE models based on GTAP 8. The results showed that in all countries, except Singapore have the most of growth in agricultural output during 1961-2010 are from TFP, while Singapore comes from the capital. Agricultural TFP growth in China (1.97 percent) higher than the TFP ASEAN-5 (1.93 percent), but less than TFP Malaysia (3.40 percent) and Thailand (2.37 percent). Indonesia with agricultural TFP growth of 1.83 percent, indicating that Indonesia is less productive and less efficient in producing agricultural products than China, Malaysia and Thailand. China agricultural products also have larger market share in global market than ASEAN-5. Furthermore, the coefficient of transmission of international prices to domestic markets of each ASEAN-5 countries and China is small, but there are indications of short-term integration in most commodity crops in China and the long-term integration of plantation commodities in ASEAN-5. ACFTA generally have a positive impact on increasing the GDP in each ASEAN-5 countries, but Indonesia will get the smallest increase in GDP. ACFTA also increase people's consumption and sectoral output, but potentially lower government consumption and investment in each country. Liberalization, it also causes the trade deficit for most agricultural commodities Indonesia. Furthermore, it was found that the liberalization that accompanied an increase in agricultural TFP and price transmission in Indonesia will provide a greater positive impact of increased exports, private consumption and GDP, but the decline in government consumption and investment spending will also increase. Even this scenario is likely to reduce employment in the agricultural sector primary. Such scenarios also increase the income of all households in Indonesia, but farm households and rural households under the class get the smallest increase in revenue

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.
