Trema ( Trema orientalis Linn. Blume) is a potential multipurpose tree species belongs to Cannabaceae, that can be used for producing biomass energy, light construction, charcoal and herbal medicine. In relation to the seed procurement, the objective of this research is to find out the effect of sieve mesh size for seed selection of trema to seed viability and seedling growth. The research design used completely random design with treatments of (1) control (without using sieve mesh), (2) 1.18 mm in size of sieve mesh, (3) and 1.70 mm in size of sieve mesh. Every treatment contains 4 replications. The observed parameters were of Germination Percentage (GP), Germination Rate (GR), seedling height and seedling diameter. The results of this research indicated : (1) the sieve mesh size has been significantly influence the GP, GR, seedling height and seedling diameter, (2)1.70 mm in size of sieve mesh was the best method for seed selection of trema, with the average of 83% in GP, 4.2391 %/etmal in SG, 13.6 cm for seedling height and 2.1 mm in seedling diameter.
