The Effect of Different Methods to Determine Log Volume and Their Impacts to Veneer Recovery

Veneer production has not been determined precisely from the log consumption due to plywood production varies from year to year. This research has studied the influence of various factors: stem diameter, water content, density and form quotient on veneer recovery. In addition to these factors, it is assumed that different methods to determine the volume of logs can produce different veneer recovery. Model from the analysis of factors influencing the veneer recovery is very useful to predict the number of veneers produced, as well as to predict the amount of plywood produced from the amount of raw materials available. Allegedly, the determination of the volume of different methods will produce different veneer recovery. Determination of the volume with Brereton and Integral formula were selected as the best estimate for veneer recovery by chi square test. Chi square test showed that the volume of log and veneer recovery by Brereton and Integral were not different.
