The use of wood for a specific purpose can be done by considering the level of wood durability against wood-destroying organisms. The purpose of this study was to analyze the weight loss and durability level of six types of sawmill industries in Pringgarata District Pemepek Village, Central Lombok using the grave yard test method. This research method used a non-factorial Completely Randomized Design (CRD), including the preparation and making of test samples, testing the natural durability of wood, and determining the resistance class and weight loss of wood after the burial test. The results showed that the value of the loss of weight of the natural durability of sawmill industrial wood in Pemepek Village, Pringgarata District, Central Lombok against subterranean termite attacks with the grave yard test ranged from 3.43 to 8.10%, with moisture content below 10% and a density of 0.34 to 0.89 gr/cm3. The species of wood did not significantly affect the weight loss of wood, but significantly affected the moisture content and density of wood. Overall, the types of sawmill for the wood industry in Pemepek Village, Pringgarata District, Central Lombok is in the clases I, II, and III, classified as highly to moderately resistant
