Cadangan Karbon Pada Tegakan Pohon Hutan Kota Di Taman Margasatwa Ragunan Dki Jakarta

Abstract

Increase environmental problems, such as air pollution and temperatures increase in DKI Jakarta, make the existence of urban forests very important. Trees have an important role becausethey function as the most efficient carbon sink and storage in urban areas. Along with the<br />increasing number of visitors carrying vehicles, the higher the potential for air pollution in Ragunan Wildlife Park (TMR). The objectives of this study are: To analyze the community structure of tree species that have potential carbon stocks, and estimate carbon stocks stored in tree trunks. The study was conducted in four regions (north, west, east, south) Ragunan Wildlife<br />Park, DKI Jakarta. Vegetation analysis was carried out by calculating the Important Value Index (INP), and carbon stock analysis was carried out through the Allometric approach. The highest INP value was mahoni (Swietinia macrophylla) amounting to 45.51%, cengal pasir (Hopea<br />odorata) 33.31%, and dao (Dracontomelon dao) 28.26%. The largest amount of carbon reserves is found in the western region, which is 52,503 kg / ha, and the largest contribution of carbon stocks is from dao trees (Dracontomelon dao) of 30,091 kg / ha, cengal sand 25,372 kg / ha, oil<br />palm (Elaeis guinensis).

Potential of carbon storage and sequestration in the Heroes Park City Forest, Purworejo Regency, Central Java

“…S. macrophylla or mahogany is the third-highest dominant tree in Heroes Park. The same thing was also reported in the Taman Margasatwa Ragunan City Forest, which was dominated by S. macrophylla [39] The abiotic measurements of air temperature and humidity at the time of sampling were 28.85 °C and 64.82%. Rainfall recorded in February 2021 around Heroes Park was 436.5 mm month -1 because it was entering the peak of the rainy season [47].…”

“…Faktor lingkungan yang dimaksud antara lain sinar matahari, kadar air, besaran suhu dan kesuburan tanah yang akan berpengaruh pada laju fotosintesis. Besarnya biomassa ditentukan oleh diameter, tinggi tanaman, kerapatan kayu, dan kesuburan tanah (Banjarnahor et al, 2018;Azizah et al, 2019;Sedjarawan et al, 2014).…”

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)

“…Perbedaan nilai biomassa dan serapan CO2 di masing-masing lokasi kajian juga dipengaruhi oleh jumlah dan kerapatan pohon, diameter pohon, jenis pohon, tajuk pohon, faktor lingkungan yang meliputi penyinaran matahari, kadar air, suhu, dan kesuburan tanah yang mempengaruhi laju fotosintesis. Besarnya biomassa ditentukan oleh diameter, tinggi tanaman, kerapatan kayu, dan kesuburan tanah (Banjarnahor, Setiawan, & Darmawan, 2018;Azizah et al, 2019;Sedjarawan, Akhbar, & Heriyanto, 2014).…”
