Tusam seed is categorized as orthodox's seed, but its viability will decrease fast if the seed is storage improperly. Seed sortation is one of methods for increasing the seed viability. The research was aimed to find the best sortation method through soakin in H2O and to know the relationship between germination and leaccheate conductivity of tusam seed. The research was using seed proviously storage for 4 months in room chamber, with viability and vigor of 50,75% and 5,70%/etmal respectively. The experiment design was completely randomized design, the analyzed factor were soaking period (0,2,3,4 hours) and the kind of seed (shifted and sunk seeds). The relationship between germination and leaccheate conductivity were analyzed with regression model. The result revealed that the best sortation method was soaking the sunk seeds in the water for 3 hours. The treatment increases the germination capacity 16,75% and the speed of germination 2,75%/etmal (47,71%). The seed had relatively low leaccheate conductivity (0.15 mSg -1) and high percentage of seeds with good quality to be distributed (63,13%). The result of regression analysis showed that the higher leaccheate conductivity the lower germination capacity, that can be expressed as Y= -91,078 +78,855, R2= 0,5536 (Y=germination capacity, x=actual conductivity).
