This study aims to develop a suitable method for calculating and processing carbon
sequestration in Dipterocarpus alatus Roxb using appropriate algebraic equations. The study
data includes (1) the collection of algebraic equations, (2) the coefficients of small and large
Dipterocarpus alatus Roxb, and (3) NPK values in the soil. The objective is to select a suitable
equation for developing a simple tool to calculate carbon sequestration in Dipterocarpus
alatus Roxb using only height and diameter data. The input data has undergone feedback and
suggestions from experts and has been tested by calculating the carbon sequestration of 10
Dipterocarpus alatus Roxb, revealing a total sequestration of 173,855.14 kilograms.
Additionally, (2) the measurements of variables related to the carbon sequestration process
in Dipterocarpus alatus Roxb showed that the net rate of carbon sequestration in small trees
is lower than in large trees. This is attributed, in part, to the smaller size and differences in
height and circumference, resulting in a lower rate of carbon sequestration in small trees.
