Carbon absorption capability of single-leaf and compound-leaf plants in the BNI Urban Forest, Banda Aceh

Abstract

The creation of Open Green Spaces is one of the options for mitigating the impact of global warming. In order to maximize the function of urban forests as carbon dioxide absorbers, plant species selection for urban forests must be considered. The goal of this study was to compare the ability of single-leaf and compound-leaved plants growing in urban forests to absorb carbon dioxide. Exploratory survey methods with purposive sampling were used. The single-leaf plant, B. asiatica (520 cm2), had the maximum leaf area, whereas the single-leaf species, M. elengi had the lowest leaf area (47.50 cm2). The plant with the highest water content in leaves was found in single-leaf plants, B. asiatica (ranging from 74.67 percent to 77.32 percent), while plant F.decipiens from the compound-leaf plant had the lowest water content (ranging from 44.34 percent to 46.14 percent). The plant with the highest percentage of carbohydrate mass at 06.00 am was M. elengi (531.63 percent), and the plant with the lowest percentage of carbohydrate mass was P.indicus (211.15 percent). At 11 am, the compound-leaf plant S.mahogani (496.76 percent) had the largest percentage of carbohydrate mass, B.asiatica had the lowest (289.29 percent). B.asiatica had the most carbon dioxide absorption per leaf area per hour (g/leaf/hour), whereas S. mahogany had the lowest. S.mahogani (32.514 Å) had the highest chlorophyll concentration in the 06.00 am sample, while P.indicus had the highest chlorophyll concentration in the 11.00 am sample (42.440 Å).

Effect of Farming Systems on Soil Carbon Sequestration and Crop Yield of Paddy (Oryza sativa L.) in Irrigated Rice Field

“…Photosynthesis is the process of converting carbon dioxide (CO2) from the atmosphere and water (H2O) from soil and water vapor into oxygen (O2) and glucose (C6H12O6) (Nagy et al, 2010). This process increases the need for photosynthetic materials by absorbing carbon dioxide (Daud et al, 2021). The increased photosynthesis followed by nutrient uptake by plants can improve products in glucose, which is translocated and accumulated into the grain (Hidayati et al, 2016).…”

“…Plant production can be measured precisely for the CO2 used in photosynthesis [63], [64], [65]. The percentage of carbohydrates produced during photosynthesis can be used to determine the mass of CO2 absorbed by plants [66]. Leaves exposed to sunlight speed of CO2 absorption in the photosynthesis process was higher than shaded leaves [59], [62], [67].…”
