Characterization of Chemical Components in the Wood and Bark of <i>Anthocephalus cadamba</i> and <i>Anthocephalus macrophyllus</i> from Progeny Trial in Wonogiri, Indonesia

Jabon ( Anthocephalus spp.) is a fast-growing species with considerable potential for pulp and paper production in Indonesia. This study aims to determine the chemical component in wood and bark of 10-year-old Anthocephalus cadamba (families 23, 11, and 6) and 5-year-old Anthocephalus macrophyllus (families 75, 85, and 2) in the bottom part of the trees. The results showed that chemical properties of A. cadamba in the wood and bark, i.e., holocellulose, α-cellulose, hemicellulose, and Klason lignin content ranged from 62.66 to 75.75%, 32.42 to 48.43%, 26.72 to 34.42%, and 22.80 to 35.10%, respectively. The levels of holocellulose and α-cellulose in these species are in the high class. High holocellulose and cellulose content indicates high pulp yield, which will benefit the pulp and paper industry, especially F6 and F2.
