ANALYSIS OF AVAILABILITY AND NEEDS OF GREEN OPEN SPACE IN KENDARI, SOUTHEAST SULAWESI, INDONESIA
Climate change caused by various factors of environmental damage is a phenomenon that occurs in all aspects of human life on this earth. Especially urban areas, which has become the center of civilization and the economy has suffered severe environmental damage.Green open space is a space that can be covered with trees or other plants, which, although narrow, but may help in reducing the effects, of environmental degradation.
Studies on the content of biomass and carbon stored in the green open space is very important to determine the ability of green open space to absorb carbon. This research involves various sectors that cause carbon emissions in Kendari the capital city of Southeast Sulawesi Province in Indonesia, namely from the transport sector, industry and trade, education and office and residential activities. This research was conducted in three areas, namely business district, offices and settlements.
The availability of green open space based on the calculation of the absorption of CO2 and produce O2 as well as the calculation of the availability of the number of trees to produce O2 and absorb CO2.The needs of green open space is calculated based on the needs of oxygen in humans and vehicles, carbon emissions in humans, vehicles, and household electronic equipment and green open space broad needs and the number of trees to absorb carbon dioxide and produce oxygen in the business district, offices and settlements. The results showed that the availability of green space based on oxygen consumption in the business district should have a green open space covering 61% of the total area, the settlement area must have a comprehensive RTH minimum of 15.3% of the area of the region, which means a minimum area of RTH not eligible based on oxygen demand, while for an office area, the existing green open space area is 53.16% that an area has exceeded the minimum requirement of extensive green open space based on the need for oxygen. It is relevant to a comparison of emissions and carbon deposits in the three regions, namely the business area amounted to 0.2189 tons of carbon savings with the amount of emissions to 3.5 tons per day, the settlement area total carbon storage is 62.545 producing an emission of 10.6 tons per day, while the office area produces carbon deposits is amounted to 5,464.93 tons per day by the number of emissions of 34.3 tons per day.
