Abstrak: Infrastruktur memainkan peranan penting dalam pembangunan ekonomi terutama di negara sedang berkembang seperti Indonesia. Namun demikian untuk mewujudkan pembangunan wilayah perkotaan yang berkelanjutan dibutuhkan infrastruktur yang mendukung tidak hanya untuk kepentingan ekonomi saja tetapi juga mendukung sistem sosial budaya dan sistem ekologi secara terpadu., Infrastructure plays an important role in economic development, especially in developing country such as Indonesia Nevertheless, the development of infrastructure for sustainable urban and regional development is still constrained by socio economic and environmental condition as well as of lack of integrated development model This dissertation attempts to develop policy model of integrated infrastructure development toward the creation of urban sustainability. The analysis was carried out using both quantitative and qualitative assessments. A FLAG approach which indicates the degree of sustainability and linkages analysis between dimensions of sustainability was used, where system dynamic approach (VENSDvf) was used to determine the time path and behavior of socio-economic-environmental variables in relation with infrastructure development and-Multi Development Scaling with statistical method for rapid appraisal of sustainability (MDS/STFRA) was also needed to measure the integration of infrastructure development and sustainability. Using the cluster city of Kedungsepur (Kendal, Demak, Ungaran, Semarang and Purwodadi) as a case study, the result most likely predicted that this area is facing a critical environmental condition The Flag/DA SHBOARD results indicate that most of these cities are under critical condition in terms of sustainability. While the system dynamic (VENSLKf) indicated that there is tremendous pressure of socio¬Economic-Environmental variables hi these cities. The result from MDS/STRFA indicated that integrated urban development and urban sustainability of Kedungsepur are still under performance (below average). Therefore, it is important to develop an integrated policy model to promote integration of urban infrastructure in this area and other cities in Indonesia. A policy model of urban Infrastructure is needed to adopt the way to enhance the community in heaving symmetric perception of the urban problems and challenges in order to create more participative decision making process in urban infrastructure development planning. The role of universities and research institutes are becoming more importance in handling the knowledge management and as leverage factor in educating the community's perception The Infrastructure development priority in this urban area which is so far more concentrated in supporting the improvement of socio-economic growth need to be focused to the improvement of environmental condition as reflected in the local goverment's budget. The leverage factors of integrated policy model as mentioned should be considered in the structure of policy model of urban infrastructure development

Judul: Model Kebijakan Pembangunan Infrastruktur Berkelanjutan (Studi Kasus: Kota Bandarlampung)
Abstrak: Infrastructure development does not only affect the economic aspect, but also social and environmental, those are the main dimensions of sustainable development. Many aspects and actors involved in infrastructure development requires a comprehensive and integrated policy towards sustainability. Therefore, it is necessary to formulate an infrastructure development policy that considers various dimensions of sustainable development. The main objective of this research is to formulate policy of sustainable infrastructure development, with specific objectives are: firstly, to measure the level of sustainability of the city's infrastructure; secondly, to formulate the indicators that influence the sustainability of city infrastructure development and thirdly, to design a policy model of sustainable urban infrastructure with dynamic system. This research was conducted in Bandarlampung City. The scope of research is the urban infrastructure which as a basic network infrastructure that influence urban development, namely: transportation, water system (drinking water, storm water, waste water), green open space system and solid waste system. The key indicators of this study were obtained from the assessment of stakeholders, public opinion and assessment of the existing infrastructure planning documents. This study use a comprehensive modeling, namely the Multi Dimensional Scaling (MDS) with Rapid Appraisal of Infrastructure (Rapinfra) to measure the level of sustainability of urban infrastructure development and search key indicators, and it uses of Analytic Network Process (ANP) to determine the effect indicators of sustainable infrastructure development. The findings of the MDS analysis showed that the status of Bandarlampung City infrastructure sustainability is less sustainable with the index value of 38.05 %. ANP analysis produces 8 main indicators of the most influential in the development of sustainable infrastructure consist of: air quality, growth of built up area, community participation, citizen behavior, local economic growth, water availability, infrastructure planning and infrastructure budgets. The dynamic model offered 4 scenarios of sustainable urban infrastructure policy model. The best scenario was implemented into 3 policies consist of: the integrated infrastructure management, the population control, and the local economy development. The results of this study are expected to be useful for stakeholders, especially the governments as a reference in the development of sustainable urban infrastructure development policy.

Judul: Penapisan Inhibitor Tirosinase pada Empat Spesies Famili Asteraceae Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, dan Tagetes erecta.
Abstrak: The research was conducted to screen the potency of tyrosinase inhibitor from 4 species of Asteraceae family. The screening was performed on the leaves and flowers of Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, and Tagetes erecta. The samples were dried and then extracted with nhexane, ethyl acetate, and methanol. The inhibition activity was tested by a microplate reader spectrophotometer in 492 nm. The ethyl acetate extract of D. rosea Cav flower was the most potent tyrosinase inhibitor (IC50 for monophenolase 18.42 μg/mL and for diphenolase 687.79 μg/mL) compared with the other Asteraceae species. The most active essential oils as inhibitor of tyrosinase was obtained from T. erecta flower (IC50 for monophenolase 1882.62 μg/mL and for diphenolase 1884.33 μg/mL). Positive control used was kojic acid with IC50 value of 11.02 μg/mL for monophenolase and 84.19 μg/mL for diphenolase. Fractionation of the extract by preparative thin layer chromatography with chloroform as mobile phase gave 12 fractions. The most active fraction had IC50 of 5.55 μg/mL for monophenolase and 109.96 μg/mL for diphenolase, and was identified as flavonoid.
