PENDUGAAN CADANGAN KARBON PADA TAMAN HUTAN KOTA BOGOR

Abstract

Climate change driven by increasing carbon dioxide (CO₂) emissions necessitates mitigation efforts, including the utilization of urban green spaces. This study aims to estimate tree volume, biomass content, and carbon stock in four urban forest parks located in the City of Bogor: Taman Peranginan, Taman Heulang, Taman Kencana, and Taman Ekspresi Sempur. Field data were collected through direct measurement of tree diameter at breast height (DBH), tree height, species identification, and wood density estimation. Tree volume was calculated using a cylindrical approximation formula, biomass was estimated using the allometric model of Chave et al. (2014), and carbon stock was derived assuming that 47% of dry biomass constitutes carbon, based on IPCC 2019 guidelines. The results indicate that Taman Heulang has the highest carbon stock at 275 tons, followed by Taman Kencana (220.8 tons), Taman Peranginan (220 tons), and Taman Ekspresi Sempur (195 tons). Tree volume and carbon stock were significantly influenced by DBH, height, wood density, and species composition. Heavy-wooded species such as Mahogany (Swietenia mahagoni), Banyan (Ficus benjamina), and Teak (Tectona grandis) stored the largest amounts of carbon. Parks with higher species diversity and larger-diameter trees demonstrated greater carbon storage capacity. This study confirms that urban forest parks play a significant role in climate change mitigation and should be managed according to sustainable ecological principles.
