The germination process of arabica coffee bean takes a fairly longtime, due to
semi-permeable skin against water. Dormancy treatment needs to improve germination rate of coffee beans before planting. The research was conducted at The Compost Centre of Agriculture Faculty, University of Sumatera Utara from July – September 2018 using a Randomized Complex Design (RCD) non-factorial with 5 treatments, i.e. P0 (Control), P1 (Stripping Bark Horn),
P2 (Soaking in KNO3 0,5% 24 hours), P3 (Soaking in Sitokinin 1,5 ml/lt 24 hours), P4 (Soaking in Coconut water5days). The parameters observed were potential to grow, germination rate, vigor rate, germination speed index, normal sprout percentage, and death percentage. The result showed that stripping coffee beans had statistically significant increase on potential to grow, germination rate, vigor rate, germination speed index, normal sprout percentage and decrease on death percentage.
