| dc.description.abstract | 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
