Interaction between Marine Sectors using System Dynamics for Patimban Deep Sea Port as a Green Port: A Proposed Model

Abstract

Based on Marine Policy Statement (MPS) some sectors are chosen as the key elements, whose interactions are modeled using system dynamics (SD). They are port, commercial shipping, marine protected area, and commercial fishing. Besides those, according to MPS and beyond the coastal area conversion of agricultural land into the industrial area due to commercial shipping, maintenance of state roads due to port (shifting from Tanjung Priok port), redistribution of population, and environmental aspects will also be taken into account in the model. Some of the elements will construct reinforcing (R+) loops, while the others construct balancing (B-) loops in finding an equilibrium or solution. Several scenarios are proposed, where each has a different set of parameters, that can reflect a certain policy. Due to the lack of certain data and information related to the deep seaport, most of the data used in this work are based on assumptions but with a logical causal relationship between elements. It is observed that some features in the results are as expected, but some are new and depend on the chosen scenario. Further benchmarks with real situations are required for validation of the model.
