SPATIAL ANALYSIS OF PUBLIC GREEN SPACE EFFECTIVENESS BASED ON CARBON DIOXIDE (CO2) EMISSION IN MALANG CITY, EAST JAVA, INDONESIARUSLAN WIROSOEDARMO, BAMBANG SUHARTO, YOHANES GIYAI, KIKI GUSTINASARI AND AULIA NUR MUSTAQIMANAbstract Green space in urban areas is an important aspect that influences CO2 absorption from several urban activities such as LPG fuel consumption, motorized vehicles transportation, and human respiration. In 2015, the area of Green Space in Malang City was 10.93% while the land area for settlements reached 36.5%. The area of Malang City is 11,006 ha, with a population density of 7.735 people / km2. Hence, it has the potential to increase CO2 emissions. The purpose of this study is to analyze the absorption capacity and the distribution of public green space with the level of CO2 emission in Malang City. Quantitative descriptive method applied in this study to determine the amount of CO2 emission load and the absorption capacity of Public Greenspace. Spatial Model Method using ArcView 10.1 Software application was used to describe and compare the adequacy of CO2 and Public Greenspace distribution based on CO2 absorption capacity in Malang City. The total CO2 emissions generated from the use of LPG, Motorized Vehicles and Respiration were 486,931,879,943 kg/year. The total absorptive capacity of CO2 emissions by Public Green space was 64,514,004,429 kg/year. Total unabsorbed emissions were 422,417,875,514 kg / year. Increased CO2 absorption can be done by scaling up the number of trees by considering tree species that have high CO2 absorbing ability in the sub-district which has the highest amount of unabsorbed emissions in Malang City, such as in Kedungkandang District, Lowokwaru District, Sukun District, and Blimbing District.
