Potensi Biomassa Dan Karbon Tersimpan Tegakan di Ruang Terbuka Hijau Kota Polewali, Sulawesi Barat

Abstract

Global warming is one of the major environmental issues of this century. Carbon dioxide (CO2) emissions are the main cause of global warming. Green open space (RTH) such as urban parks, urban forests and green lines play an important role in mitigating global warming and climate change in urban areas because it is able to reduce CO2 from the atmosphere. This study aims to determine the potential of biomass and carbon stored in the Green Open Green Space of Polewali, West Sulawesi. Data collection for stored biomass and carbon is carried out at three green space locations including; Urban forest and city park and green lane each made three plots measuring 20 m x 20 m, and three plots on the Green Line measuring 1200 m. Retrieval of data by measuring tree height and diameter, analysis to obtain the dry volume, biomass and carbon stored for each tree species contained in the Polewali green space. Biomass is obtained by the formula M = BJ x Vk x BEF, the stored carbon value is obtained from the product of biomass by 0.47. The magnitude of the relationship of volume with biomass and carbon uses a regression equation (Ŷ=a+bX). The results show there are types of Glodokan (Polyalthia longifolia), Johar (Senna siamea), Mahogany (Swetenia sp) and Trambesi (Samanea saman) which are spread in the Polewali open green space. Trambesi is a type that has dominant biomass and stored carbon of 381.95 (tons / ha) and 179.52 (ton/ha). Green lane is the type of green space that has the most stored carbon and is currently 440.94 (ton/ha) and 207.24 (ton/ha). The overall green space biomass is 571.83 (ton/ha) and stored carbon is 268.76 (ton/ha) found in urban forests, urban gardens and green belt. The relationship of volume with biomass and stored carbon shows a very strong relationship with the coefficient of determination (R2) of 0.96.

Structure, Composition, Carbon Stocks of Dipterocarpaceae in West Batang Toru Forest Block, North Tapanuli Regency, North Sumatra

“…Biomass and carbon stocks are determined by stand composition, age, circumference, and soil factors within the study area. Irundu et al [25] highlighted that carbon storage isn't influenced by a single parameter but by multiple factors like tree size, species diversity, and individual density. Dharmawan [26] suggested that the diameter class impacts stored biomass and carbon, where larger tree diameters absorb more carbon.…”

“…Another thing that affects the value of carbon stocks is the value of tree biomass. According to Irundu et al (2020) and Indrajaya (2017), tree biomass can be determined by tree diameter, tree species diversity, number of individual trees, and tree density.…”

“…This condition causes an increase in the ability of trees to store carbon from nature (Mustikaningrum, 2023). According to Komul et al (2016) and Sribianti et al (2022), trees have a large trunk diameter. This is because the results of the photosynthesis process are stored in the stem, causing the stem diameter to increase.…”

“…Komul et al (2016) stated that trees have a higher biomass value than other habitus, because they have a trunk diameter of more than 20 cm. Sribianti et al (2022) proved in their research that the tree stage has the largest average amount of biomass of 103.68 tonnes per ha, because the tree stage has the largest diameter compared to the other levels. In addition, Rahim et al (2018) also explained that the tree trunk has the greatest biomass compared to the root part of the tree.…”
