Abstrak: Land conversion is a term that describes phenomenon of changing land- use from one to other uses permanently. Factors closely associated with land conversion were population growth, economic, and infrastructure development. This study aims are (1) to determine rate and pattern of farmland conversion in Tangerang District, (2) to know growth rate of population density, economic growth, and development of Tangerang District, and (3) to determine factors affecting conversion of agricultural land in Tangerang District. Land conversion in Tangerang District caused areas of agricultural land decreased 2.4% per year. The agricultural lands were converted into built land. Population density grew unevenly in Tangerang District. The highest population density growth rate occurred ( during 1997-2007 ) in Pasar Kemis (19% ) and Kronjo faced the lowest rate (0.2%). The economic growth rate in the Tangerang District can be seen from the 1997-2007 Gross Regional Domestic Product (GRDP) Tangerang District. In general, service sector has the highest growth rate (3.9%) followed b y industrial sector (0.9%) and agriculture sector (0.6%). Meanwhile, mining sector decreased by 4.1% per year. Level of development in Tangerang District analyzed with skalogram shows that in 2003 most of the villages (60.98%) were on 3rd hierarchy, while the rest on 2nd hierarchy (30.18%) and 1st hierarchy (8.84%). In the year 2006, there were an increase in number of villages on 2nd hierarchy and a decrease in number of villages on 3rd hierarchy, while the number of villages on 1st hierarchy were the same. Factors with high significant (p-level <0.05) influencing agricultural land conversion were GRDP growth of services sector, GRDP of agricultural sector, GRDP of manufacturing industry, educational facilities, economic facilities, accessibility to health facilities, and accessibility to government centre, whereas accessibility to educational facilities was the significant factor (p-level <0.1).

Abstrak: Fluctuation on land conversion in Tangerang Regency is occurred annualy. Average lan conversion in Tangerang Regency was 0,706 percent per year. In this study, land construction area, numbers of industrial area, and rice field productivity were factors causing agricultural land conversion on the regional level. Factors affected agricultural land conversions on the farm level were residential period, farming experience, seed prices, and its selling prices. As a result, land conversion impacted on the average total farmers‟ income changes before and after the conversion which was decreased Rp 1.100.833. the average income before the land conversion was Rp 3.649.167 while after conversion was Rp 2.548.333. in addition, agricultural land conversion also caused a decrease on rice production. The average loss of rice production was equal to 3561,41 tonnes per hectare per year, while the average loss of production value was Rp 15.313.335.440 per year (grain form) and Rp 24.928.685.600 per year (rice form). Based on food security simulatio, Tangerang Regency would not meet its rice demand by 2014 with 1.169 tons of rice shortage. Moreover, if decline on the rice demand 1,5 percent per year, Tangerang Regency would not meet its rice demand in 2018 with 7.454 tons of rice shortage.

Judul: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
