Abstract
Ruang terbuka hijau merupakan penyerap CO2 yang efektif untuk wilayah perkotaan. Kawasan perkotaan merupakan sumber karbon dioksida yang besar. Surabaya adalah salah satu kota terbesar di Indonesia. Peningkatan pembangunan di surabaya terutama sektor komersial menyebabkan proporsi RTH semakin sedikit. Hal itu menyebabkan berkurangnya kemampuan serapan karbon dioksida di wilayah tersebut. Selain itu, kawasan komersial merupakan kawasan yang padat aktifitas manusia sehingga menyebabkan peningkatan produksi CO2 udara ambien di kawasan tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh proporsi RTH dan non RTH (seperti: luas bangunan, badan air, tanah kosong, jalanan) terhadap nilai serapan karbon dioksida di kawasan komersial Kecamatan Genteng Kota Surabaya. Manfaat penelitian ini yaitu didapatkan model persamaan proporsi RTH yang ideal untuk kawasan komersial dengan mengetahui bagaimana pengaruh proporsi RTH serta non RTH (seperti: luas bangunan, badan air, tanah kosong, jalanan) terhadap serapan CO2 kawasan tersebut. Sebelum dilakukan penelitian ditentukan dulu titik sampling. Titik sampling ditentukan secara acak sederhana. Kemudian dihitung proporsi RTH, non RTH (seperti: luas bangunan, badan air, tanah kosong, jalanan) tiap wilayah sampling dengan metode delienasi. Lalu, Penelitian ini dilakukan dengan melakukan pengukuran konsentrasi karbon dioksida udara ambien, arah angin dan kecepaan angin selang waktu 12 jam di beberapa titik sampling. Kemudian didapatkan data konsentrasi CO2 selama 12 jam. Pengukuran dilakukan untuk 5 hari kerja dan 2 hari libur selama 7 hari (senin-minggu). Kemudian, Didapatkan persamaan konsentrasi CO2 selama 12 jam. Lalu, Dilakukan deferensi persamaan konsentrasi untuk mendapatkan persamaan laju konsentrasi dc/dt. Setelah itu, Dilakukan integrasi untuk mendapatkan nilai kumulatif konsentrasi karbon dioksida selama 12 jam , atau nilai kumulatif konsentrasi karbon dioksida (Net-CO2-Con). Nilai Net-CO2-Con bertanda negatif bila terjadi serapan , sebaliknya bertanda positif bila terjadai emisi. Terakhir, dilakukan analisis statistika (regresi, korelasi, signifikansi) untuk mengetahui pengaruh proporsi RTH dan non RTH (seperti: luas bangunan, badan air, tanah kosong, jalanan) terhadap nilai kumulatif karbon dioksida. Hasil karbon dioksida rata rata akhir yang didapatkan adalah sebesar 358,01 ppmv hal ini lebih besar dari baku mutu udara ambien CO2 yakni sebesar 310-330 ppmv. Kemudian hasil perhitungan Net-CO2-Con pada 24 titik lokasi menunjukkkan hasil rata rata positif sehingga dapat disimpulkan pada kawasan komersial terjadi emisi CO2 ambien dengan kata lain RTH di kawasan komersial masih belum efektif dan memerlukan perencanaan. Berdasarkann uji korelasi, regresi dan signifikansi semua variabel berpengaruh secara signifikan terhadap Net-CO2-Con yakni proporsi rth, jalan dan tanah, bangunan, serta badan air. Setelah dilakukan perhitungan didapatkan model luasan proporsi RTH terhadap Net-CO2-Con yakni y = -51,143 x + 69,5209. Persamaan model tersebut dapat digunakan untuk mengetahui luasan kebutuhan RTH apabila diketahui konsentrasi CO2. Dimana y adalah konsentrasi CO2 sedangkan x adalah proporsi RTH yang diharapkan.

Green open space is an effective CO2 absorber for urban areas. Urban areas are a large source of carbon dioxide. Surabaya is one of the largest cities in Indonesia. Increased development Surabaya, especially in the commercial sector, has caused smaller proportion of green open space. This causes a reduction in carbon dioxide uptake in the region. In addition, the commercial area is an area that is densely populated with human activities which increases CO2 production in the region. This study aims to determine the effect of the proportion of green open space and non green open space (such as: building area, body of water, vacant land, roads) to the value of carbon dioxide uptake in the commercial area of Surabaya, Genteng District. The benefits of this study is that will be found the ideal model of the proportion of green open space for the commercial areas by knowing how the effects of the proportion of the green open space and non green open space (such as building are, water bodies, vacant land, roads) to the CO2 absorption of the area. Before doing the research, the sampling point is determined first. The sampling point is determined by simple random sampling methods. Then the proportion of RTH, non (such as: building area, body of water, vacant land, roads) is calculated for each sampling area using delienation methods. Then, this research was conducted by measuring the concentration of carbon dioxide ambient air, wind direction and wind speed within 12 hours at several sampling points. Then the CO2 concentration data for 12 hours was obtained. Measurements are carried out for 5 working days and 2 days off for 7 days (Monday-Sunday). Then, CO2 concentration equation for 12 hours was obtained. Then, differentiate the concentration equation to get the conversion rate equation dc / dt. After that, integration was carried out to get the cumulative value of carbon dioxide concentration for 12 hours, or the cumulative value of carbon dioxide concentration (Net-CO2-Con). The value of Net-CO2-Con is negative if there is absorption, otherwise it is positive if there is an emission. Finally, a statistical analysis is conducted to determine the effect of the proportion of green open space and non green open space (such as: building area, water bodies, vacant land, roads) to the value of carbon dioxide cummulatives. Based on the results, the final average carbon dioxide obtained is equal to 358.01 ppm, this is greater than the ambient air CO2 quality standard which is equal to 310-330 ppmv. Then the calculation of Net-CO2-Con at 24 location points shows the positive average results, So it can be concluded that in the commercial area is still not effective. Because land use has an effect of 71% on net CO2, it is necessary to conduct a green open space study based on the model in the commercial area of Genteng, Surabaya. Based on correlation, regression, and significance test. All variabel tested have a significance effect for ambient air net CO2 like Green Open Space Proportion, Street and Vacant Land, Water Bodies. and Commercial Building. After the statistical analysist. we got some models that can determine the proportion of green open space by the concentration of CO2 in that area. The models are y = -51,143 x + 69,5209. Where, y is concentration of CO2 and x is the proportion we gonna find.
