BIOMASSA DAN KARBON PADA TEGAKAN HUTAN TANAMAN JABON (Anthocephalus cadamba Miq) DI KABUPATEN PASANGKAYU PROVINSI SULAWESI BARAT

Abstract

Utilization of land into forests is one of the activities that can increase carbon sequestration. Jabon is a type of tree that has high prospects for industrial plantations and reforestation plants. This study aims to estimate the amount of biomass and carbon in Jabon (Anthocephalus cadamba Miq) forest plant stands, which 3 and 5 years old in Pasangkayu Regency, West Sulawesi Province. This research was conducted for three months, namely from June to September 2019, conducted in Pasangkayu Regency, West Sulawesi Province. And in the soil science laboratory, Faculty of Agriculture, Tadulako University, Palu. Tree biomass estimation uses non-destructive methods or allometric equations, while estimation of understorey biomass uses destructive methods by collecting all the plant samples in the plot. The results of this study indicate the amount of stand biomass aged 3 years is 86.27 tons / ha, and 5 years 342.81 tons / ha, the amount of understorey biomass in the 3 years stand is 0.65 tons / ha, and 5 years 1 ton / ha . The amount of carbon in the 3-year stand is 38.82 tons / ha, and in 5 years 154.26 tons / ha, the amount of carbon of undergrowth in the 3 year stand is 0.29 tons / ha, and 5 years is 0.45 tons / ha. In the Jabon stand 3 years old it has an average biomass of 17.38 tons / ha and carbon 7.82 tons / ha. Whereas at the age of 5 years, the average biomass is 68.76 tons / ha and carbon is 30.94 tons / ha. Comparison of average biomass of 51.38 tons / ha, carbon of 23.12 tons / ha. Jabon 3-5 years old can produce above ground biomass and carbon 25.69 tons / ha / yr and 11.56 tons / ha / yr, respectively.
