Abstract

This study examines the air-drying rate of 2”x4”x4’ short-length commercial green falcata (Falcataria falcata) lumber in Butuan City, Philippines, specifically during September to December 2024. It aims to determine the drying duration required to achieve moisture contents of 15%, 20%, and 25%, which are critical for preventing fungal decay and improving lumber stability and usability. A total of 24 lumber samples were collected and monitored under ambient conditions, with 2” sample segments taken from lumber ends periodically, including ¼” trim ends. The results revealed significant variation in drying times across stacking months, with September showing the fastest drying (20 days to 15% MC) and December the slowest (77 days). Regression analyses indicated that drying behavior follows either linear or non-linear patterns, with polynomial and exponential models being the best fit. These findings provide a localized and practical reference for air-drying estimates, contributing to efficient and sustainable lumber processing practices in the Caraga Region.
