Abstract

Urban green spaces are essential for sustainable urban development due to their role in providing ecosystem services, particularly carbon sequestration through urban vegetation. This study assesses the carbon absorption capacity of trees in two Indonesian city parks: Taman Indonesia Kaya (TIK) in Semarang and Taman Singha Merjosari (TSM) in Malang, using the i-Tree Eco model with standardized measurements of seven tree parameters, including diameter at breast height (DBH), total height, and crown structure. Results show that TIK, with 142 individuals and 33 species, has a higher total carbon absorption (2390.9 kg C/year), while TSM, with 131 individuals and 14 species, demonstrates greater absorption efficiency per species, primarily due to the presence of broad canopied, nitrogen-fixing trees. However, the Mann-Whitney U test confirms that TSM is more effective in carbon sequestration than TIK. Based on these findings, five strategic planting recommendations are proposed: prioritizing high-biomass species, integrating native species, optimizing canopy and root space, minimizing excessive pruning, and conducting regular tree monitoring. Despite limitations in measurement timing and site-specific variability, this study provides empirical evidence to inform urban greening policies. It highlights the importance of species selection and tree management strategies to enhance the carbon sequestration potential and ecological resilience of urban parks in tropical cities.
