Abstract

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. Key words: sustainable environmental management, coastal and marine zone, dynamic and spatial dynamic system, waterfront policy strategy

Abstract

This research to study relation between environment parameter, plankton abundance and primary productivity with abundance of tiger prawn post larvae and milk fish fry, calculates plankton predating rate speed by tiger prawn post larvae and milk fish fry and other larva and studies plankton population dynamics, tiger prawn post larvae and milk fish fry before, at the time and after peak season.  Result of research indicates that some environment parameters significant differs according to observation period and season.  Highest abundance of tiger prawn post larva, milk fish fry and other larva reaches to 29067, 7733 and 54400 ind/1000 m3. Highest grazing rate to population of phytoplankton and plankton (phytoplankton + zooplankton) found when predator consisted of tiger prawn post larva, milk fish fry and other larva with grazing rate up to 125 cells/liter/hour and 129 plankter /liter/hour respectively.  Highest predating rate to zooplankton population when predator consist of tiger prawn post larva and milk fish fry and there is phytoplankton as their prey up to 12 individual/liter/hour.  The certain plankton species significant correlation and estimated as natural food of tiger prawn post larva and milk fish fry that is some types of diatom and crustaceae from zooplankton.  Plankton population dynamics especially controlled by predator by tiger prawn post larva, milk fish fry and other larva, while influence of environment parameter is small relative. Abundance of each phytoplankton and zooplankton ranged from 583-28563 cells/liter and 22-3413 ind/liter.  Average abundance of phytoplankton and zooplankton significant differs higher at peak season compare  before and after tiger prawn post larva and milk fish fry season. Predator-prey relation between phytoplankton and zooplankton shows phase change which succession between phytoplankton controls to zooplankton phases with zooplankton control to phytoplankton.  Abundance of plankton influences abundance of population of tiger prawn post larva and milk fish fry especially after peak season.  There is concordance of time between peak abundance of tiger prawn post larva and milk fish fry and other larva with peak abundance of phytoplankton and zooplankton.   Key words : population dynamics, predating, predating rate, predator, prey, phytoplankton, zooplankton, tiger prawn post larva, milk fish fry, other larva, Pinrang

Abstract

Semarang waterfront is a unique ecosystem which has a variety potentialities and problem of using some natural resources, especially in the trade-off between economic growth and ecological preservation.  Generally the handling operation of waterfront city in Indonesia is not effective, caused by (1) low budged and increase the poverty; (2) over loaded investment; (3) destroyed of ecology and ecosystem; (4) the lost of local wisdom; and (5) other problem in commonly urban city.  Based on these conditions, this research aimed to design an environmental management policy ensuring a profitable synergy of all stakeholders without sacrificing the principles of environmental conservation.  The objective of this study was to analyze the index and sustainability status of the Semarang waterfront area, based on five sustainable dimensions.  Secondary data resources have been used from literature study and references, primary data have been received from questionairy feedback and expert judgement survey.  The analysis  used multi dimensional scalling (MDS) method, called Rap-WITEPA, and the results were stated in the index and sustainability status.The second objective was to analyze the attributes that affect sensitivity on index and sustainability status and the effect of error using Laverage and Monte Carlo Analysis.  The result of this study show that ecological dimension was in the status of less sustainable (49,34), economical dimension was sufficient sustainable (53,96), socio-culture dimension was sufficient sustainable (52,21), dimension of infrastructure and technology was sufficient sustainable (56,72) and dimension of law & institutional was the highest sufficient sustainability value index (57,19).  Out of 94 attributes analyzed, there were 50 attributes need to be handled immediately as they affect sensitivity on the increase of index and sustainability status with negligible error in the level of 95% confidence limit.  It was concluded that an important factor of waterfront city handling operation design in Semarang is social community development, land use efficiency, industry contribution, electricity, and local society organization.   Key words: sustainability index, sustainability status, waterfront city
