Semarang waterfront city is a unique ecosystem with a great variety of potentialities as well as problems in the utilization of natural resources, particularly in the trade-off between economic growth and ecological preservation. Based on those conditions, the research is mainly focused upon designing some scenarios on environmental management, which ensure a profitable synergy of all stakeholders without sacrificing the principles of environmental conservation. Secondly, it is to design an interaction model among variables in the bio-physic, economy and social subsystems, in order to increase sources of learning and sustainable use of natural resources. Using a dynamic system, the main inputs of the designed model are the feasibility of natural resources management as a product of extended cost-benefit analysis (ECBA), the suitable option of natural resources management, as an input of comparative performance index (CPI), the integrated sustainability of using multidimensional scaling, the suitable land-use planning through geographic information system (GIS). From those main inputs the waterfront city environmental management policy can be observed as an output of analytical hierarchy processes (AHP). The feasibility study shows that all of natural resources management options are feasible to be developed, where sustainable management, sustainable harvest and beach protected areas depict the most feasible management options. Based on the results of the integrated sustainability research using multidimension scaling, the management of waterfront cities has to prioritize attention to the five important factors, i.e., (1) the issues of community empowerment; (2) the rate of land utilization; (3) the contribution of the industrial sector; (4) the availability of electricity and; (5) the availability of community organizations.

Between 1992-2005 there were 8 tsunamis occurred in Indonesia. At 17 July 2006 tsunami reached the southern coast of West Java, Cilacap and Yogyakarta. Tsunamis had caused heavy destruction and death. The aim of the study is to find out spatially the potential of inundation area by tsunami wave based on the distribution of inundation extent of different run up. The run up of 7.5 m flooded 4% from whole study area. 36% of the area was flooded by 15 m run up. When the run up was 7,5 m, some areas were flooded reaching 200 m from the coast and there were also some points going further to 1 km. The run up of 15 m moved further to 4,5 km. The information on the distance and extent of inundation from some possible run up of tsunami become an input on potential areas flooded by water and having destruction.

Bogor Botanical Gardens (Kebun Raya Bogor/KRB) has a long history of medicinal plants conservation. In order to improve the quality of the medicinal plant collections and its uses, KRB need to manage relevant on public and visitor expectation and key aspects of medicinal plant conservation. This study aims to establish the KRB management strategy for the medicinal plants collection. A set of questionnaires used in this study. The data were processed using the Likert scale, scoring, and the AHP (analytic hierarchy process). The study suggested a total of 60 species that need more attention. Of the 60 species assessed 9 species were prioritised including Anaxagorea javanica, Coscinium fenestratum, Eusideroxylon zwageri, Heritiera littoralis, Kadsura scandens, Santalum album, Lunasia amara, Scorodocarpus borneensis, and Terminalia bellirica. Three basic conservation aspects (tri-stimulus amar) and the key KRB functions need to be strengthened and established and yet to be in line with the public expectation in order to achieve an integrated medicinal plant ex situ conservation.

High blood cholesterol in human might cause atheroskelerosis, a disease that eventually leads to the occurrence of coronary heart attack. This research was aimed to investigate level of sago waste or shrimp waste on plasma cholesterol and growth in rats. The experiment was conducted on 28 males Spraque dowley rat of one month old and was set up in a completely randomized design with seven treatments and four replications. The treatments were R0 (0 % sago waste and srimp meal) as a control, ASA 10 (10% of sago waste), ASA 20% (20% of sago waste), ASAF 10% (10% fermentation of sago waste), ASAF 20% (20% fermentation of sago waste), LU 10% (10% of srimp waste), LU 20% (20% of srimp waste). Variables measured included feed intake, body weight gain, plasma cholesterol, high density lipoprotein, low density lipoprotein, and triglyceride. The results showed that there was non-significant decrease in feed intake, whereas on body weight gain showed significant effect (P<0.05) between ASA 20%, ASAF 20% and LU 20%. Feed eficiency showed significant effect (P < 0, 01) between R0, ASA 20%, LU 10% with LU 20%. There was significant differences (P < 0.05) in plasma cholesterol between ASA 20% and R0, ASA 10%, LU 10% and 10% of ASAF, while HDL, LDL and plasma triglyceride did not indicate a significant effect between treatment. It is concluded that percentages of sago waste, fermentation of sago waste and shrimp waste in the ration as an effort to reduce cholesterol do not give a positive effect on feed intake, HDL, LDL and plasma triglyceride of rats; giving 20% of sago waste, 10% of fermentation of sago waste and 10% of shrimp waste showed significant effect on body weight gain, and the highest was obtained at a given ration ASA 20%, i.e. 3.55 g; giving ASA 20% has the highest feed eficiency that is 0.31; giving 20% of sago waste, fermentated sago waste and shrimp waste reduce cholesterol level significantly. The lowest plasma cholesterol was obtained at 20% ASA treatment that is 59.75 mg/dl.

In order to achieve planning consensus, involvement of stakeholders in coastal zone management, have to be concerned. The participatory prospective analysis (PPA) is a comprehensive and quickly operational framework designed to fulfill the demand for a well-structured effort of anticipation and exploration, that also focuses on interactions and consensus building among stakeholders. PPA was carried out through an expert meeting for coastal zone management planning, as a part of developing system of coastal zone spatial planning, in Lampung Bay. The PPA was aimed to involve stakeholders to generate identification and definition of key variables, definition of the states of variables in the future, building scenarios, and formulation of strategic implications and anticipated actions for coastal zone management. A number of 27 participants from various representative backgrounds, i.e.: local government, fisherman and aqua culturist, local people and entrepreneurs, and local university, was involved in experts meeting. As a result was obtained 6 variables that have the largest influence in coastal zone management of Lampung Bay, they are: quality of human resource, law enforcement, population growth, regional infrastructure, local economic activities, and regional zoning. Consensually, participants was invented strategic implications and anticipated actions, that have to be accommodated in coastal zone management, they are: (1) accomplish requirement of infrastructure and facilities of health and education; (2) develop of micro, small, and medium business (MSMB) centers that associated with marine and fisheries; (3) accomplish requirement of housing that comprise proper infrastructure and sanitation facilities; (4) assembly synergy on spatial arrangement among cities and regencies; (5) assembly spatial arrangement which able to drive development of MSMB in coastal zone; (6) assembly spatial arrangement which able to drive proportional distribution of population in coastal zone, and also proportionally secure the management of conservation and production areas. Finally, it is concluded that: (1) the PPA could accomplish direct interactions among stakeholders intensively and generate consensus opinions; (2) the PPA could be a platform for stakeholders involvement in order to establish keys variable of planning, define future states of variables, scenarios building, and strategic implications and anticipated actions for integrated planning of coastal zone of Lampung Bay; (3) stakeholders involvement is the key of simplification of policies formulation for integrated planning of coastal zone of Lampung Bay, in which various of interest could be accommodated.
