The impact of urban development is the rapid growth of the urban population, causing a decrease in the density of green open space. This study aims to describe the current condition of green open space in Panakkukang District as a target of its development to maintain the ecological balance and disaster mitigation function. The analytical method used is superimposed and quantitative descriptive based on population needs to be based on area, population density analysis, oxygen fulfillment analysis, and analysis of evacuation space utilization. This study shows that the current size of green open space in each village in the district has become much smaller; the highest need for green open space based on oxygen fulfillment is in Tammamaung village with an area of 56.31 ha; based on its area is the Panakkukang village of 109.85 ha, and based on the total population in the village of Tammamaung around 56.14 ha. Factors influencing changes in the size of green open space in Panakkukang Regency are the allocation of green open space in the Spatial Plan, economic facilities, number of visitors, population density, and educational facilities, and the development of green open spaces from parks, urban forests, and cemeteries. Green open space from the road lane is made on the primary and secondary road lane while the development of green open space on the river border is set to be 5 to 20 meters from the riverside. Roads, parking areas, parks, and urban forests are used as evacuation spaces for disaster mitigation.
