Abstract

Antrian kendaraan pada gerbang tol Karawaci 3 mengakibatkan meningkatnya konsentrasi emisi gas karbon dioksida (CO2). Kondisi vegetasi eksisting kurang memadai sehingga tidak mampu mereduksi CO2 pada gerbang tol Karawaci 3. Vegetasi memiliki manfaat dalam menyerap konsentrasi emisi CO2. Berdsarkan permasalahan tersebut, diperlukan kajian untuk mengukur konsentrasi emisi CO2 yang dihasilkan oleh kendaraan bermotor dari pagi hingga sore hari, berdasarkan nilai konsentrasi tersebut dapat dihitung nilai reduksi Net_CO2- Con tiap area box untuk mengetahui kemampuan penyerapan konsentrasi CO2 dan perlu ditetapkan koefisien faktor apa saja yang berpengaruh terhadap serapan konsentrasi CO2 pada gerbang tol Karawaci 3. Penelitian ini dilakukan dengan metode box untuk mengukur konsentrasi emisi CO2 di enam titik yang merepresentasikan kondisi udara ambien di gerbang tol Karawaci 3. Dalam satu hari pengukuran dilakukan sebanyak lima kali dengan rentang waktu 2-3 jam sebanyak enam kali pengulangan. Nilai reduksi Net_CO2-Con dihitung berdasarkan perhitungan integrasi dan diferensiasi. Ditetapkan besar persentase proporsi vegetasi, persentase non-vegetasi dan ditentukan jarak box menuju gerbang tol. Hasil tersebut dilakukan uji statistik dengan metode uji korelasi dan uji regresi untuk mengetahui pengaruh proporsi vegetasi, non vegetasi dan jarak box menuju gerbang tol terhadap nilai reduksi Net_CO2-Con sehingga didapatkan persamaan matematis yang sesuai. Konsentrasi emisi CO2 udara ambien pada gerbang tol Karawaci 3 selama 12 jam pengukuran berkisar antara 390,26 hingga 499,78 ppmV. Konsentrasi CO2 udara ambien hasil pengukuran tidak memenuhi standar baku mutu konsentrasi CO2 yang ditetapkan oleh WHO (World Health Organization). Nilai rata-rata reduksi Net_CO2-Con berkisar -103,323 hingga - 166,993 ppmV, tanda negatif menandakan reduksi CO2 pada titik pengukuran. Koefisien faktor yang berpengaruh terhadap nilai rata-rata reduksi Net_CO2-Con didapatkan dengan uji regresi, koefisien hasil uji regresi dibuat persamaan regresi linier berganda Net_CO2-Con = 30,325(Proporsi Vegetasi) + 29,715(Proporsi Jalan) - 158,236. Berdasarkan persamaan tersebut menunjukkan adanya reduksi yang terjadi pada area gerbang tol Karawaci 3, kondisi vegetasi yang terdapat pada gerbang tol Karawaci 3 dinilai sudah cukup untuk menyerap konsentrasi emisi CO2. =====================================================================================================================================
The queue of vehicles at the Karawaci 3 toll gate results in an increase in the concentration of carbon dioxide (CO2) gas emissions. The existing vegetation condition is inadequate so that it is unable to reduce CO2 at the Karawaci 3 toll gate. Vegetation has benefits in absorbing CO2 emission concentrations. A study is needed to measure the concentration of CO2 emissions produced by motorized vehicles from morning to evening. Based on the concentration value, the reduction value of Net_CO2-Con can be calculated for each area of the box to determine the absorption capacity of CO2 concentration. It is also necessary to determine what factor coefficients are needed. It affects the absorption of CO2 concentration at the Karawaci 3 toll gate. This research was conducted using the box method to measure the concentration of CO2 emissions at six points representing ambient air conditions at the Karawaci 3 toll gate. In one day, the measurements were carried out five times, with a time span of 2-3 hours, six times. The Net_CO2-Con reduction value is calculated based on integration and differentiation calculations. The percentage of vegetation is determined, the percentage of non-vegetation is determined, and the distance from the box to the toll gate is determined. The results were statistically tested using the correlation test method and regression test to determine the effect of the proportion of vegetation, non-vegetation and the distance of the box to the toll gate on the reduction value of Net_CO2-Con in order to obtain the appropriate mathematical equation. The ambient air CO2 emission concentration at the Karawaci 3 toll gate for 12 hours of measurement ranged from 390,26 to 499,78 ppmV. The ambient air CO2 concentration measured does not meet the quality standard of CO2 concentration set by WHO (World Health Organization). The average value of Net_CO2-Con reduction ranges from -103,323 to -166,993 ppmV. A negative sign indicates CO2 reduction at the measurement point. The coefficient of the factors that affect the average value of Net_CO2-Con reduction is obtained by regression testing. The coefficient of the regression test results is made up of multiple linear regression equations. Net_CO2-Con = 30,325 (Vegetation Proportion) + 29,715 (Road Proportion) - 158,236. Based on this equation, it shows that there is a reduction that occurs in the Karawaci 3 toll gate area. The vegetation condition found at the Karawaci 3 toll gate is considered sufficient to absorb the concentration of CO2 emissions
