STUDY OF THE POTENTIAL OF CO2 ABSORPTION BY VEGETATION BASED ON NORMALIZED DIFFERENCE VEGETATION INDEX (NDVI) VALUE

Konversi, 2021
Abstrak: Peningkatan gas rumah kaca (GRK) sebagai salah satu penyebab perubahan iklim. Salah satu gas yang berperan pada GRK adalah karbon dioksida (CO2). Kandungan CO2 di atmosfer diduga meningkat sekitar 0.03-0.06% dan menyebabkan kenaikan suhu sebesar 4.25°F (Fardiaz 1992). Hutan berperan dalam upaya peningkatan penyerapan CO2.
