Abstract

The Linggua (P. indicus) is a multipurpose tree with a considerable distribution; nevertheless, the IUCN has classified it as an endangered species. The tree species has great potential to be included in the REDD + mitigation program in handling climate change. REDD + has made it possible to implement carbon trading. Thus, countries that can manage forest properly, and implement reforestation, are able to partake in carbon trading with the rest of the world. Therefore, research was conducted to determine the level of absorption of carbon dioxide (CO2) and water content (H2O), as this is a preliminary step in determining the allometric equation for the Linggua tree type. The sampling of tree species through damage (destructive sampling) was carried out by cutting down 3 young trees. The methods used include field observation and laboratory analysis for the determination of water content and biomass in the treatment, which involved the use of a spectrophotometer. The results of the water content P. indicus starting from the roots, base of stem, middle, tip and successive leaves: 79.99%; 72.40%; 82.44%; 80.34% and 83.45%. The Total biomass content on 3 tree samples is: the chest diameter of 15 cm, 15.5 cm and 16 cm respectively, 34.9589, 43.7536 and 52.4008 tons. If only the biomass on the ground alone is 34.9552, 43.7484 and 52.3998 tons. Total Carbon stock on trees with diameter at breast height of 15 cm, 15.5 cm and 16 cm are 12.7040; 19.3348 and 24.5020 tons respectively and CO2 Carbon sinks: 46.6239589, 43.7536 and 52.4008 tons respectively.
