Judul: Design policy models and strategies of service level management of toll roads (Jakarta- cikampek toll roads case study)
Abstrak: Toll roads are public roads that are part of road network system and a national road users are required to pay tolls. While the definition of highway is a certain amount of money paid for the use of toll roads. Minimum service standards under the authority of the central government (Article 2 paragraph 4 item b.). MSS held to ensure the availability of the service road to the public in the most minimum conditions. Minimum Service Standards for toll roads has been provided for in Regulation Minister of Public Works No. 392/PRT/M/2005. MSS is a measure that must be achieved in the implementation of toll road and organized to improve the public service as a toll road users. The purpose of this study is the subject as follows (1) Model determined the policies and strategies capable of dealing with problems of the physical condition of highways, traffic management and land use and maintain the level of highway service (MSS) remains appropriate, and (2) Realization of environmental management model that can address environmental issues in order to prevent or reduce air pollution caused by transportation and traffic noise in the area around the highway. Results showed that growth in traffic volume on toll roads is quite high, if not controlled it will result in the management and operation of toll roads including the physical condition of the components of toll roads, traffic management and land use components will result in a decreased level of highway service or in other words Standard Minimum Service (MSS) is not fulfilled (Minimum Service Standards in accordance Regulation Minister of Public Works No. 392/PRT/M/2005), and growth of high traffic volumes will result in environmental problems in this study was limited only to the level of air pollution and noise levels that occur on the interstate.

Judul: Analisis faktor-faktor yang mempengaruhi perkembangan jalan tol di Indonesia
Abstrak: The toll road is one of the critical infrastructure that plays a role in national development and economic growth. But since 1978 until now Indonesia has just able to build about 700 km. This is very much in comparison of Malaysia has been able to build a toll road to 1500 km. In improving the construction of toll roads, since 1987 the Indonesian government has implemented a governmentprivate cooperation for financing the construction of toll roads because of limited funds owned by the government. So that private investors have the opportunity to participate in the procurement of toll roads for the community. This study uses secondary data period of 1987-2009 using multiple linear regression analysis. However, due to the multicollinearity problem of data transformation is carried out by using the Principal Component Analysis (PCA). The goal is to eliminate the high correlation between independent variables. The analysis showed that the GDP per capita, labor, government funds, private investment, and the number of four-wheeled vehicles and more. In addition the dummy of policy is also positive and significant influence on the development of the toll road which is described by the length of the toll road. Dummy of policys described by establishment the Toll Road Regulatory Agency (BPJT) in 2005 as a toll road regulator replaces the dual function of Jasa Marga as operators as well as regulators.

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
