The document presents a model using system dynamics to simulate interactions between marine sectors at the proposed Patimban Deep Sea Port, emphasizing the benefits of green technology policies. Results indicate that implementing such policies can enhance GDP for both the port and surrounding urban areas, while maintaining population levels. The findings suggest a promising future for developing green ports in sustainability and resilience of coastal management.

System dynamics

4. System dynamics applications
• System Dynamics (SD) has been used a lot in
coastal area, e.g.
– for improving value of ecosystem services in
Shinduri coastal area in South Korea (You et al.,
2018)
– for managing sustainable tourism using a decision
support system in Cijin, Kaohsiung, Taiwan (Tan et
al., 2018)

– for predicting the sustainablity of tuna ranching
industry in Mexico (Robadue & del Moral
Simanek, 2007)
– for simulating forward scenario of sustainability
landscape in Cimandiri Estuary, West Java,
Indonesia (Supriatna et al., 2016)
– for assessing of the impacts of storm damage on
coastal communities in Chabahar Bay, Iran
(Moradi et al., 2020)

– for conceptualizing social-ecological system dyna-
mics in the Bangladesh delta (Hossain et al., 2020)

9. Model
• There five main nodes
– Green Technology
– Population
– Interstate Infrastructure / Industry
– Port-driven GDP
– Urban GDP
• The last two are the central nodes, while the

• It shows that implementation of Green Tech-
nology policy give some benefits than the con-
ventional one, such as higher GDP for port and
the city nearby but with relatively the same
population
• These results show a promising future of the
development of a green port for Patimbang
