For many purpose, either plainsawn and quartersawn lumber is satisfactory. Each type has certain advantages that can be important for a particular use. This paper will discuss the level of efficient approach needs size boards in the market (> 10cm) of two types of sawmill (quartersawn and plainsawn), and the effectiveness of the two types based on the percentage of the volume of the end result of sawmil
