Judul: Pembangunan Infrastruktur Jalan dan Jumlah Penduduk Terhadap Pertumbuhan Ekonomi DKI Jakarta Periode 2002-2012
Abstrak: The role of road infrastructure is needed to improve economic growth in Jakarta. Infrastructure is a factor that is needed for economic development. The aim of this research is to analyze the impacts of road infrastructure development and population on economic growth in Jakarta. This research use the model of data panel 5 kotamadya in city in 2002-2012. The result showed that the length of roads (PJ ) positive influence on economic growth in Jakarta population ( PNDDK ), of investing an alien ( PMA ) positive influence on economic growth in Jakarta and investment in the country ( PMDN ) positive influence on economic growth in Jakarta. To create economic growth in Jakarta the role of the government required quite big in terms of facilities and infrastructure adequate infrastructure, such as mass transportation construction to reduce traffic congestion and conduct fair distribution development.

Judul: Pengaruh Infrastruktur terhadap Pertumbuhan Ekonomi dan Kebijakan Pembangunan Jalan di Kabupaten Bogor
Abstrak: Infrastructure has a very important role on economic growth. The purpose of this research is for describing economic and infrastructure growth, analyzing the effect of infrastructure on economic growth and analyzing road policy priority in Bogor Regency. Secondary data is acquired from the data that has been used since 1989 to 2012, while primary data is acquired from interview and questionnaire. The variable used are Regional Gross Domestic Product (millions of Rupiahs), the number of health center (unit), the amount of fresh water channeled (m³) and road length (km). Results obtained by using the regression that the health center infrastructure, water and roads have a positive and significant effect on economic growth. Results from the AHP method shows that first target priority is raising employment by adding road length, the second priority is increasing economic growth by adding road facility and third priority is reducing poverty by adding the road length.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
