Abstract
Some studies about climate change in Jakarta have revealed that air pollution and water supply has reached a critical level, and one of the efforts to reduce that climate change impact is to increase green areas. Under Indonesian Law No. 26/2007 the proportion of ideal green area in big cities like Jakarta is 30% of the total city areas; unfortunately at this time the green area in Jakarta is only 9.84%. The effort to increase green areas in Jakarta requires huge funds, since the price of land in Jakarta is very expensive. On the other hand, green space is a critical requirement to provide clean air and water supply. This study aims to find an optimum number of green areas in Jakarta. Optimization of green areas will be done using the goal programming method. The results of this study revealed that the optimum amount of green area in Jakarta is 19.62% or 129,800,045 m2. With the land costs assumptions at 2 million rupiahs per m2, the fund should be prepared to increase the green space from 9.84% to 19.62% at 129.413 trillion rupiahs. It is hoped that the findings of the research can be used as the basis for communities and policy makers to increase green space in Jakarta.
