Abstract

The objective of this work was to determine the volumetric yield coefficient of four forest species studied in the city of Itaituba - PA, according to different logs obtained from the trunk and the type and year of the machinery used. It will also seek to compare the coefficients obtained with the established in the specific legislation and to suggest an ideal amount of sample effort to meet the precision required by the legislation. The study will be carried out in four sawmills located in the district of Moraes Almeida, municipality of Itaituba - PA. The volumes of the sample logs will be determined by the Smalian formula, discounting the volume of the hollow. The lumber volume will be determined by multiplying the thickness, width and length of each piece produced. The yield calculation is defined as the ratio between the lumber volume and the log volume, given as a percentage. The logs will be classified, according to the position in the trunk, in A, B and C to verify if there is difference of the yield between these classes. The sawmills will be separated into two groups, Group 1 with the most modern industrial park and Group 2 with the most obsolete industrial park. The ideal quantity of samples will be calculated using the formula used to determine the sample adequacy of the simple random sampling process. The Analysis of Variance and the Tukey test at 95% of probability will be used to verify if there will be difference between the means, having as a response variable the CRV. Sections of the trunk and the sawmills will be the treatments to be compared. The yields found in all cases are expected to exceed 35% and that logs closest to the base of the trunk show a better yield compared to top logs and that the group of companies which own the most modern machinery higher yields compared to older machines. It is expected to recommend the ideal number of logs to estimate the yield of the species studied.
