Carbon Footprint Calculation of Net CO2 in Agroforestry and Agroindustry of Gayo Arabica Coffee, Indonesia.

Carbon dioxide (CO₂) in the atmosphere occurs as the result of various chemical, physical, and biological processes. The presence of CO₂ around atmosphere greatly affects the agroforestry and agroindustry of coffee. This study aimed to describe the CO₂ cycle in agroforestry and agroindustry of Gayo Arabica coffee (Coffea arabica) and net CO₂ ha^-1 of coffee plantation. CO₂ cycle was analyzed based on the movement of CO₂ around the agroforestry and agroindustry of coffee. CO₂ cycle model describes net CO₂, CO₂ emission, CO₂ reduction, and CO₂ sequestration. Net CO₂ ha^-1 of coffee plantation was 162.75 x 10^-2 t CO₂ e ha-1, with CO₂ emission was 203.84 x 10^-2 t CO₂ e ha^-1, CO₂ reduction was 3.10 x 10^-2 t CO₂ e ha^-1, and CO₂ sequestration was 363.49 x 10^-2 t CO₂ e ha^-1. This research formulates the calculation of equivalent carbon emissions in the arabica coffee production system in the field and primary processing, using various methods (remote sensing analysis and calculation of direct and indirect equivalent carbon emissions). The CO₂ cycle positively impacts the sustainability of agroforestry and agroindustry of Gayo Arabica coffee. [ABSTRACT FROM AUTHOR]
