Stomata is a tiny hole on the epidermis cells on stem or leaf. The function of stomata is to regulate water loss during transpiration and absorption of CO₂ process, as well as in the photosynthesis process. This research was aimed to determine the stomata shape, size and density on the leaves of 5 arabica coffee varieties The experiment used a completely randomized design, with six varieties of Arabica coffee namely  Kartika 1, Kartika 2, S 795, Sigarar Utang, and Kopyol Bali. The results showed that the shape of stomata on seven varieties of coffee were all parasitic having 2 stomata guard cells. Based stomata density, Sigarar Utang and S 795 variety are more resistant to drought than the others. This variety can also be used for land conservation.
