This research aims to determine the effect of atonic immersion and concentration and its interaction on germination of teak seeds. This study used a randomized block design consisting of 2 factors, namely immersion time (6 days, 9 days and 12 days) and atonic concentration (0 ml / l solution, 0.5 ml / l solution, 1 ml / l solution and 1, 5 ml / l solution). Variables observed included seeds starting to germinate, end of germination, germination time, seeds not germinating, seed germination, seed germination, growth rate of sprouts, growing sprouts and height of 60-day-old sprouts. The results showed that the immersion time had a very significant effect on the seed germination, the seeds did not germinate, the seeds were damaged, the seeds germinated, the growth rate of sprouts, growing sprouts and the height of the 60-day age sprout. Whereas the other variables have no significant effect. The length of seed immersion for 9 days showed the best results for the seeds that began to germinate the fastest, 5 days, the smallest germination seeds were 12.33%, the most germinating seeds were 28.83%, the growth rate of sprouts was 2.57% per etmal and sprouts that grow at 23%. But in the high variable 60 day age sprouts, soaking time for 12 days gave the highest yield of 14.56 cm. The atonic concentration had a very significant effect on the damaged seeds and the seeds germinated and significantly affected the seeds began to germinate, the seeds did not germinate, the growth rate of sprouts, growing sprouts and the height of the 60-day age sprouts. Whereas the other variables have no significant effect. Atonic concentration of 1.5 ml / l showed the lowest damaged seed yield of 12.67%, the highest germinating seed was 26%. The interaction between 9 days of immersion time and atonic concentration of 1.5 ml / l solution showed the best results compared to other interactions.
