System Dynamics Modeling for Green Open Space Analysis A Case Study of Medan City,Indonesia

Objective of this research is to develop a model of green open
space management aimed at development of green cities in
Medan city. (1). The simulation results suggest that a decline
occurs in the area of green open spaces throughout the
simulation year period, i.e. from 10,830.06Ha (2003) to
4,411.28 Ha (2028); the total population during the simulation
year period which formerly was equal to 1,993,602
inhabitants (2003) will have increased to 2,620,700
inhabitants (2028); while the temperature from 27.80oC (2003)
increases to 28.50oC (2028); and finally, GDRP during the
simulation year period which formerly was equal to IDR
28.670 billion (2003) increases to IDR 406.880 billion (2028).
(2). There are two strategies for green city development in
Medan City, namely: 1. The population policy strategy by
means of controlling population growth in the downtown area
as well as directing the population growth toward the area
outside the downtown, namely towards the districts whose
population density is relatively still very low. 2. The policy
strategy in the form of green open spaces for the public,
which is undertaken by improving The the quantity and
quality of green open spaces for city parks and city forests.
