    Coffee is a significant commodity in Indonesia, and the two most widely cultivated coffee species are Arabica and Robusta. This study aims to compare the yield stability of Arabica and Robusta coffee in Indonesia, and the performance of regions from the viewpoint of yield stability. Using the Yield Stability Index, the study measures yield stability over a 10-year period (2011-2020) using data from Directorate General of Estates, Ministry of Agriculture. Results show, that the two coffee varieties considerably differ in their stabilities, and the stability of yields across regions also show large discrepancies. While Robusta yields were stable in all the 33 analyzed regions, though to a different extent, for Arabica, produced in 20 regions, only 4 could produce stable yields. The yield stability of Indonesian coffee is influenced by a complex interplay of environmental factors, agronomic, and socio-economic factors. Mitigating these yield stability challenges requires a multifaceted approach.
