Potential utilization of agarwood residues from twigs and branches is supported by its chemical content and fiber quality. This study aimed to analyze the chemical content and fiber quality of agarwood branches (Aquilaria malaccensis Lamk). Parameters measured in this study were the chemical contents including extractives, holocellulose, alpha cellulose and lignin based on Technical Association of Pulp and Paper Industries (TAPPI) standard. Fibers were obtained after pulping and bleaching to determine its quality. Chemical analysis of the primary branch of agarwood revealed the composition of extractives which were soluble in cold water (2.71%), hot water (3.31%), ethanol benzene (3.81%), and 1% NaOH (10.03%). The proportion of holocellulose, alpha cellulose and lignin in the primary branch was 78.17%, 52.70% and 26.68%, respectively. In addition, the chemical analysis of the secondary branch of agarwood also revealed the soluble extractives in cold water (2.96%), hot water (3.49%), ethanol benzene (4.14%), and 1% NaOH (14.42%). The proportion of holocellulose, alpha cellulose and lignin in the secondary branch was 75.61%, 50.65% and 26.77%. Hence, the fiber quality of agarwood branches was categorized into class II.
