Population growth and rapid development in Jakarta have caused a reduction in the amount of Green Open Space (GOS) in urban areas. Based on data in 2017, the public GOS managed by the Forestry Agency is only 4.65% and the private GOS can not be counted until now. Although the target of public GOS achievement is 20%, but the green plan is only 7,514.08 ha. The aim of this study is to analyze the extent and distribution of GOS and compare it with green plan. This study used the method of Geographic Information Systems to determine the extent and distribution by comparing the GOS area in year 2011 and 2018. The next step is reviewing the green plan zone according to Jakarta Spatial Planning 2030. Based on the results of this study, it can be concluded that the area of GOS in 2011 was 3,816.34 ha (5.84%) and it decreased in 2018 to 3,473.94 ha (5.31%). The distribution of GOS spreads in 5 administrative cities, with the largest area being in the East Jakarta. The result of the comparison of GOS in 2018 with the green plan shows that there is a lack of green areas of 4,040.13 ha.

This research analyzes the criticality of Urban Green Spaces (UGS) environmental and health benefits during the COVID-19 pandemic. However, restrictions on mobility, safety concerns, and restricted access during the implementation of social distancing policies tend to use UGS to provide alternative spaces for social interaction and health. This is a severe concern to Jakarta, as the epicenter of the pandemic outbreak with limited UGS. An online survey was conducted from March to April 2021 to understand better and investigate the impact of COVID-19 on the use of UGS and behavior-changing of visitation. The results show that respondents continued to use UGS during the pandemic and considered it more beneficial for health. However, the result showed that residents’ considerations of staying active for health reasons, reduced stress, and boredom. This research provides empirical evidence illustrating the value of UGS as a resilient city infrastructure, therefore, the management policy in this city can be considered with potential application to other cities.

Rapid development and increasing population causes the green open space in Jakarta is decreasing in size every year. Green open space is one of the keys to the sustainability of a city. The purpose of this study was to analyze the area of green space, green space distribution, and deviation between the green zone plan of the Regional Regulation of RDTR PZ and existing green space in Jakarta using Geographic Information Systems. Based on satellite imagery in 2018, the area of green space in Jakarta is 3,473.94 ha (5.31%). The highest green space area in 2018 is in the green belt zone (H4) of 1,557.88 ha and the lowest in the urban forest zone (H1) is 235.13 ha. The green zoning plan based on the Regional Regulation on RDTR and PZ is only 7,520.96 ha (11.51%) and is far from the mandate stipulated in Law Number 26 Year 2007 and the Jakarta 2030 RTRW of 30%. The highest area of green open space in the Regional Regulation of RDTR and PZ is in the green belt zone (H4) of 4,539.40 ha and the lowest in the urban forest zone (H1) is 17,58 ha. Based on the comparison of the area of green space in 2018 with the green plan RDTR and PZ it is known that there are 4 administrative city areas that experience a shortage of green space, namely South Jakarta, East Jakarta, West Jakarta and North Jakarta, while for Central Jakarta it has exceeded the green plan specified.

Green open space has functions ecologically, economically, and socially to improve the quality of urban life.  Urban green space is one of the keys to sustainability. The purpose of this study was to analyze green open space planning in Jakarta and Singapore using a comparative study method. The study locations were chosen in Jakarta and Singapore because they are geographically located in Southeast Asia but have a vastly different area of ​​green open space. Singapore has the largest area of ​​green open space in the world, amounting to 47% of the total area and Jakarta only has a range of 5 to 10% because of the baseline of green open space that has not been officially set by the Government. Green open space planning in Jakarta has decreased from 1965 to the present due to the rapid development of residential and commercial areas. On the other hand, Singapore's success in increasing the area of ​​green space is due to its strong political policy in greening which is directly led by the Prime Minister and supported by all stakeholders. The vision of Singapore as a Garden City is clearly stated in the Green and Blue Master Plan and implemented in government programs. Cooperation between stakeholders in Singapore continues to make public awareness about successful greening. Jakarta needs a strong political policy to increase green open space by formulating a green open space Master Plan that is integrated with a network of roads, blue spaces, and increased cooperation between stakeholders.
