Abstract
Several endemic species of Sulawesi have different growths and are generally influenced by local environmental factors. There are three well-known endemic species of Sulawesi, namely Macadamia (Macadamia hildebrandii), Elmerillia (Elmerillia ovalis), and Gophasa (Vitex cofassus). These three species are widely developed in community forests and are the mainstay of the community as building materials and for other purposes. These three species can be used as good absorbers of carbon dioxide from the atmosphere in the context of mitigating climate change. Macadamia and Elmerillia species grow well in the highlands, while Gophasa is generally found in the lowlands. From the results of the growth analysis, it is known that Macadamia and Elmerillia are medium growing species, while gophasa are slow-growing species. The results showed that the three endemic species have a good ability to absorb carbon from the air. At the age of 20 years, these three species can store carbon which is quite high, namely 132.38 tons/ha for Macadamia, 152.04 tons/ha for Elmerillia, and 82.65 tons/ha for gophasa. When converted to the ability to absorb CO2 from the atmosphere, the three species can absorb 485.85 tons CO2/ha, 557.99 tons CO2/ha, and 303.33 tons CO2/ha, respectively.
