Abstract

The actors in the palm oil supply chain industry are the farmers, traders, crude palm oil (CPO) factories, frying-oil factories (refineries), distributors and the consumers. The farmers sell fresh fruit bunches (FFB) to the CPO factories through traders. FFB is converted into CPO which is later sold to the refineries. Refineries convert CPO into frying oil which is sold to the consumers through the distributors. There are risks due to product quality consistency, price fluctuation and supply chain continuity. This study has two objectives: (1) to develop a model to identify, evaluate and rank the risks, (2) to develop a model to identify and rank the strategies in improving their added value. Data for this study was obtained through direct interviews and questionnaires. The respondents were selected experts and industry players. The data were processed using Fuzzy Analytic Hierarchy Process (FAHP) models. The first FAHP model showed that the two most important risks were the supply chain continuity and product quality. The second FAHP model showed that the recommended strategies to improve the added values of the actors were the improvement of the infrastructure/cluster development, followed by the usage of superior seeds and cultivation techniques.

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
