PENDUGAAN BIOMASSA DAN SERAPAN KARBON DI BEBERAPA AREAL TAMAN HUTAN KOTA JAKARTA, BEKASI DAN BOGOR (Estimated Value of Biomass and Carbon Sequestration in Several Forest Park of Jakarta, Bekasi and Bogor)

Abstract

The presence of forest park as green open space in densely populated urban areas and high traffic activities such as Jakarta, Bekasi and Bogor is important in absorbing CO2. However, the function of urban forests is limited because the studies were carried out on a small scale and at separate loci. This study aimed to estimate the biomass, storage and sequestration of carbon in five green open spaces located in Jakarta and Bogor areas. Biomass was estimated by non-destructive sampling for above ground biomass. The results estimated the forest park in Kanal Banjir Timur (KBT) absorbed CO2 of 1,000.01 ton/ha/year, the forest park at head office absorbed CO2 of 937.53 ton/ha/year, Mangrove Forest Park of Muara Tawar Bekasi absorbed CO2 of 46.10 ton/ha/year, and the Bukit Golf Pantai Indah Kapuk area absorbed CO2 of 147.91 tonnes/ha/year. Meanwhile the campus Forest Park of IPB University absorbed CO2 of 0.16 ton/ha. The value difference is influenced by parameters such as size or scale of sampling areas, number of stands, diameter, height, and coefficient value for each plant species. This study is expected to contribute in providing information and data on biomass, carbon content, and absorption in urban areas.

Assessing Carbon Dioxide (CO2) Absorption Potential of Forests Around Landslides Along the Trans Palopo-Toraja Highways

“…Larger DBH would lead to higher aboveground carbon storage (Syamsudin Noor et al 2020) diameter determined the carbon storage of each stand (Istomo & Farida 2017). Plot 1 had relatively low AGB and aboveground carbon storage at sapling and pole levels, suggesting that those variables had a proportional positive correlation (Santoso et al 2021).…”

“…To calculate tree biomass. This allometric equation is used to estimate the value of tree biomass in tropical areas with large or small sizes and can also be used to calculate trees that grow in humid climate zones [17].…”

“…The biomass value above can be used to estimate the total carbon stored in each tree, assuming that approximately 50% of the carbon will be produced from the biomass obtained. To calculate carbon storage, the following formula is used [17].…”

“…Sebagian karbon yang dihasilkan oleh tanaman digunakan sebagai bahan bakar dalam proses kehidupan tanaman, sementara sebagian lainnya disimpan dalam struktur tanaman. Sebagai contoh, selulosa, yang merupakan molekul gula, menjadi zat penyusun kayu pada batang tanaman (Santoso et al 2021). Menurut Danial et al (2019) kondisi fisiologis tanaman, seperti umur dan diameter batang, mempengaruhi jumlah biomassa, penimbunan karbon, dan penyerapan karbon oleh tanaman.…”
