MAPPING OF CO2 EMISSIONS TO IMPROVE THE FUNCTION OF GREEN OPEN SPACE (RTH) IN KEDIRI CITYLISANUDIN RAHMAN, MOHAMMAD RAZIF, SAMSUDIN AFFANDI3, MOCHAMAD JUNAIDI HIDAYAT, SATRIA FADIL PERSADA AND PRAWIRA FAJARINDRA BELGIAWANAbstract This study aims to calculate CO2 emissions from the transportation, household, and industrial sectors to be compared with the absorption capacity of CO2 by vegetation in public green open spaces in Kediri City. It is expected to improve the function of public green open spaces. The method of calculating CO2 emissions in the transportation sector was calculated from the value of the emission factor and the number of vehicles from the 2019 data. The method of calculating CO2 emissions from the household and industrial sectors was based on emission factors and fuel consumption. The calculation of CO2 emissions from the transportation sector in 2019 was 59,740,551 tons/year, while CO2 emissions from the household sector in 2019 were 4,110,028,315 tons/year. CO2 emissions from the industrial sector in 2019 were 3.19774x1,012 tons/year. Based on the results of observations and calculations, the CO2 absorption capacity of the vegetation in the public green open space in 2019 was 159,283,042 tons/year. It means that the ability to absorb 3.8% of CO2 emissions was produced by the transportation and residential sectors. Meanwhile, from the area of public green open space currently, it only reaches 8% of the total area of Kediri City. Based on the Regional Regulation of Kediri City Number 2 of 2004, the minimum area of public green open spaces is 20% of the total area of Kediri City. From the results of these calculations and observations, three clusters have been compiled to improve the function of green open space. R1cluster, in 17 sub-districts, needs to maintain the vegetation quality. Then, the R2 cluster, in 12 sub-districts, needs to improve the quality of its vegetation by adding vegetation that has a high ability to absorb CO2. R3 cluster, in 13 sub-districts, needs to planaplant new area of green open space by planting new vegetation with high CO2 absorption capabilities. |
