The agroforestry system is a solution offered so that the forest area does not decrease due to forest destruction and the environment is able to perform its function, namely as a carbon storage. This study was aimed to determine the potential for carbon stored in coffee stands and abiotic factors in coffee growing locations on agroforestry land. Coffee stand samples by purposive sampling, stand samples of Coffea arabica, Coffea canephora, and Coffea liberica as many as 20 trees with a total sample of 60 stands. the abiotic factor was measured at three representative points. Data obtained in the form of dbh (±1,3 m), type of coffee, plant age, wood dencity, abiotic factor data, biomass, and carbon. Data analysis included tree biomass data with the allometric formula Ketterings dry weight = 0.11 ρ D2.62 (2001) and allometric formula Arifin dry weight = 0.281 D2.0635 (2001). Data analysis included carbon biomass = dry weight x 0.47. The results showed that the largest carbon storage was in Coffea liberica, then Coffea canephora and the smallest carbon storage was in Coffea arabica. abotic factors in coffee agroforestry show soil moisture 18.3%, air humidity 75%, soil pH 7.3, soil temperature 21- 25 ° C, air temperature 21 - 25 ° C, light intensity 877 lux, and altitude ranges from 906 - 934 m asl.
