Spatial Analysis of Rubber Plant Carbon Stock Using Sentinel 2A (Case Study: Sembawa Rubber Research Center, South Sumatra Province)
Last modified: 2022-11-15
Abstract
Rubber plants as plants that can play an important role in carbon sequestration and storage. Carbon sequestration is carried out as an effort to reduce the effect of greenhouse gases in the atmosphere. The absorption capacity of carbon stock in rubber plants can be seen from the value of its biomass. This study aims to analyze the distribution of carbon stock in rubber plants and its relationship with the age of rubber plants. Distribution of carbon stock in the study area using a vegetation index approach, as well as regression and descriptive analysis. The vegetation index used is MSAVI, OSAVI, SAVI, GNDVI, and ARVI obtained from processing the Sentinel 2-A satellite imagery. The value of biomass in rubber plants is obtained from the allometric equation. The results showed that the distribution of carbon stock in almost all areas of the Sembawa Rubber Research Center. The relationship between the age of rubber plants and the carbon stock value tends to be low because it is influenced by the type of clones that have different physical characteristics, meaning that the physical parameters of the area can affect the carbon stock value of rubber plants in various age groups.
