Judul: The impact of migration policy on labor market and Indonesian economy
Abstrak: The problem of internal and international migration is still faced by Indonesian government until the recent year. The internal migration problem is related to the concentration of migration in Java as a destination region, even though this region has high population and unemployment. The problem of international migration is caused by the high demand of professional migrant of the destination country. Some of internal and international migration policies have been regulated by the government to handle the problem. The main purpose of internal and in ternational migration policies in Indonesia is to solve population distribution and labor market problem and improve economic condition in Indonesia. The objectives of this research are: (1) to describe the pattern of internal and international migration, labor market and Indonesian economy, (2) to analyze the factors that influence internal and international migration in Indonesia, and (3) to forecast the ex-ante (2009-2012) impact of some alternatives internal and international migration policies on labor market and Indonesian economy.

Judul: Faktor-faktor yang Memengaruhi Migrasi Internal di Indonesia Sebelum dan Setelah Otonomi Daerah
Abstrak: Migration is a phenomenon that occurs due to regional disparities. Many of the factors drive a person to do the migration, such as the economic growth in the region and the availability of jobs. Migration flows in Indonesia tend to be concentrated in high-income areas, while the unemployment rate is also high in the area, such as DKI Jakarta, West Java, and some other provinces. One effort to reduce the amount of migration is to perform regional autonomy. This regional autonomy provides an opportunity for each region to build their own country, which is expected to overcome regional disparities. This study aims to analyze the factors that push and pull factors affecting internal migration in Indonesia before and after the regional autonomy. The method used is the econometric model with panel data. The estimation of the model showed that variables were analyzed, namely GDP per capita, minimum wages, and population of secondary and higher education graduates, positively influence migration. Meanwhile, unemployment and dummy of regional autonomy negatively influence migration. Based on the estimation of the model, regional autonomy can reduce the amount of migration.

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.
