Background: Climate change, that is marked by improvement of earth’s surface temperature (global warming), is caused by human activities that increase the emission of greenhouse gasses to the atmosphere. These gases include CO2, N20, CH4, SF6, PFC, and HFC. Ignition of hydrocarbonic compounds such as fossil fuels (coal, petrol fuel, and natural gas) or biomass (wood) are human activity that could cause emission of greenhouse gases to the atmosphere and, further, global climate change. Methods: This study involved field-based observations with laboratory-based sample analysis. Materials used for this study consisted of 30 teak (Tectona grandis L. f.) consisting of 6 tree samples in each age group of 1 to 5 year old tree located within the KPH Balapulang area. Findings: Biomass root to shoot ratio based on main stem is about 0.1155-0.5048 (Average 0.2296), while based to surface biomass is about 0.1090-0.4317 (Average 0.1983). Carbon mass root to shoot ratio based on main stem is about 0.1159-0.5068 (Average 0.2320), while based to surface carbon mass is about 0.1111-0.4381 (Average 0.2030). Average expansion factor of biomass for age level I-V is 1.15, while average expansion factor of carbon mass for age level I-V is 1.13. Conclusion: The result of this study indicating that those ratios and factors quantify the proportion of root versus aboveground biomass or carbon and the multiplication of stem biomass or carbon to estimate total tree values. Novelty/Originality of this article: This study provides the quantitative data on root-to-shoot ratios, biomass and carbon mass expansion factors for teak (Tectona grandis L. f.) across different age classes.
