Forests certainly store biomass content which is reflected in the physical appearance of a tree. In calculating biomass directly, direct surveys and measurements are needed. Remote sensing technology, in this case, is a tool for monitoring and calculating the biomass content of vegetation. In estimating biomass using remote sensing, the biomass content of vegetation in the field is still needed. This study aimed to estimate the biomass content of the Meranti plant (Shorea parvifolia Dyer), which is the dominant plant species in the Bukit Tigapuluh National Park in Indragiri Hulu and Indragiri Hilir Regencies, Riau Province and Tebo Regencies and Tanjung Jabung Barat Regencies in Jambi Province with using Landsat 8 imagery. Field measurements and remote sensing images, which in this case are vegetation indices in the form of NDVI, ARVI, GNDVI, MSAVI2, and EVI, will produce a biomass estimation model, and the most suitable model will be selectively selected based on the strength of the relationship between the two parameters. The resulting model between the biomass value and the vegetation index will then become an estimate of the biomass of the dominant plant species in Bukit Tigapuluh National Park.
