Abstrak: Hutan kota dapat menyerap CO2 di udara melalui proses fotosintesis, penyerapan CO2 dalam proses fotosintesis ini akan menghasilkan biomassa yang merupakan simpanan karbon (carbon pool) yang terkandung dalam pohon. Teknik pengambilan data menggunakan metode sensus dan metode pengumpulan data contoh simple random sampling dengan dua luasan plot yaitu 20 x 20 m2 dan 20 x 40 m2 pada IS 100%, 50% dan 25% menggunakan persamaan alometrik Manuri et al. (2017) dan Ketterings et al. (2001). Hasil penelitian menunjukkan hasil yang lebih teliti didapatkan dengan menggunakan luasan plot dan intensitas sampling yang lebih sedangkan, hasil yang lebih akurat didapatkan dengan menggunakan luasan plot dan intensitas sampling yang lebih kecil., Urban forests can absorb CO2 in the air through the process of photosynthesis, the absorption of CO2 in this photosynthesis process will produce biomass which is a carbon pool (carbon pool) contained in trees. The data collection technique used the census method and the sample data collection method was simple random sampling with two plot areas, namely 20 x 20 m2 and 20 x 40 m2 at IS 100%, 50% and 25% using the allometric equations of Manuri et al. (2017) and Ketterings et al. (2001). The results showed that more precise results were obtained by using a larger plot area and sampling intensity, while more accurate results were obtained by using a smaller plot area and sampling intensity.

Abstrak: The increase of temperature in urban area is indirectly caused by the increase of Carbon Dioxide (CO2) concentration in the atmosphere. The increase is caused by land cover alteration and high amount of human activities which uses fossil fuel. The existence of urban forest is one of the ways to coupe the increase of CO2 concentration in the urban atmosphere. Through photosynthesis process, CO2 gas is absorbed by various plants in urban forest and afterwards being released as Oxygen (O2). To control or reduce the concentration of CO2 effectively, in the establishment of urban forest, selection of plants which have maximum ability in reducing CO2 concentration needs to be done. The objectives of this research are to obtain data CO2 sink ability of 15 urban forest plant species in Bogor Agricultural University and to obtain data about the plant species that has the effective CO2 sink ability among the plants which are measured. The measuring of CO2 sink ability was conducted using carbohydrate method. CO2 mass is obtained by converting carbohydrate mass produced in photosynthesis. Other data taken include leaf area and the number of leaves. The higher the leaf area, the higher CO2 sink ability of a leaf. The higher number leaf of a tree, the higher CO2 sink in a tree. The CO2 sink ability of 15 plant species in cm2 of leaf area are (g CO2/cm2/hour): M. caesia 3,793 x 10-4; D. indica 2,180 x 10-4; B. racemosa 1,600 x 10-4; S. campanulata 1,249 x 10-4; M. champaca 1,176 x 10-4; S. malacense 0,820 x 10-4 ; B. capitella 0,805 x 10-4; C. cauliflora 0,734 x 10-4; V. pubescens 0,669 x 10-4; C. inophyllum 0,629 x 10-4 ; M. ferrea 0,479 x 10-4; A. moluccana 0,357 x 10-4; A. dammara 0,268 x 10-4-; and G. dulcis 0,089 x 10-4. The CO2 sink ability of 15 plant species in urban forest in order from the highest are D. indica, M. caesia, S. campanulata, C. inophyllum, B. racemosa, V. pubescens, M. ferrea, C. cauliflora,B. capitella, G. dulcis, M. champaca, S. malacense, A. moluccana, and A. dammara.
