<p align="justify">Lake Cipule was a former sand mining area in Karawang Regency, West Java. The existence of Situ Cipule has <br /> <br /> causing the increament of the air temperature around the area. Around 300 trees from 20 species were planted <br /> <br /> including Mahogany (S. macrophylla), Calabur tree (M. calabura), Rain tree (S. saman), Asoka tree (P. longifolia), <br /> <br /> and Singapore almond tree (T. catappa). The existence of the tree is thought to have an effect on the decrease in air <br /> <br /> temperature around the lake through the mechanism of CO2 absorption. CO2 absorption that was part photosynthesis <br /> <br /> process is thought to be influenced by the position of the leaves in the four directions (North, East, South, and West) <br /> <br /> of the trees canopy. This study aims to determine the absorption capacity of carbon dioxide (CO2) from the five <br /> <br /> researched tree species that grow around Lake Cipule, based on the position of the leaves in the tree canopy in the <br /> <br /> North, East, South, and West directions. A total of 120 leaves from five tree species in the Lake Cipule area were <br /> <br /> taken to measure its CO2 absorption. The measurement of tree absorption capacity for carbon dioxide was carried <br /> <br /> out by the Somogyi-Nelson (1944) method to determine carbohydrate levels in the leaves sample. The results <br /> <br /> showed that the highest CO2 absorption of trees per area unit (cm2) is Mahogany (5.24 x 10-4 g cm-2 hours-1), <br /> <br /> followed by Calabur tree (4.37 x 10-4 g cm-2 hours-1), Rain tree (1.25 x 10-4 g cm-2 hours-1), Asoka tree (2.32 x 10-4 g <br /> <br /> cm-2 hours-1) and Singapore almond tree (0.41 x 10 -4 g cm-2 hours-1). However, the highest CO2 absorption per tree <br /> <br /> canopy is in Calabur tree (597.34 g cm-2 tree-1), followed by Mahogany (408.56 g cm-2 tree-1), Rain tree (374.00 g <br /> <br /> cm -2 tree-1), Asoka tree (234.70 g cm-2 tree-1), and Singapore almond tree (22.83 g cm-2 tree-1). Whereas based on <br /> <br /> the location of the leaves on the tree canopy, the highest CO2 absorption capacity from the average of the five tree <br /> <br /> species studied is in the East direction (3.61 x 10-4 g cm-2 hours-1), followed by the North direction (2.85 x 10- 4 g <br /> <br /> cm-2 hours-1), West direction (2.66 x 10-4 g cm-2 hours-1), and South direction (1.76 x 10-4 g cm-2 hours-1). From the <br /> <br /> results of the study, it can be concluded that the Mahogany has the highest CO2 absorption capability, followed by <br /> <br /> Calabur tree, Asoka tree, Rain tree, and Singapore almond tree. CO2 absorption by leaves in the East direction has <br /> <br /> the highest value, followed by the North, West and South directions. The amount of CO2 absorption in a tree is <br /> <br /> affected by the basic ability to absorb CO2 in the leaves, the surface area of the canopy, and the direction of sunlight.<p align="justify">
