In this study, lignin composition and its relationship to decomposition rate of Malaleuca<br />

Cajaputi and Aistonia Spatulata were determined. The lignin analysis was divided into<br />

two sections acid insoluble material (Klason lignin) and acid soluble material. The acid<br />

insoluble material include ash and protein, which determined by gravimetric analysis.<br />

While, the acid soluble lignin was measured by UV-Vis spectroscopy. The result shows<br />

that Malaleuca Cajaputi has slightly higher total lignin content (70.4%) compared to<br />

Aistonia Spatulata (68.4%). High lignin content in Malaleuca Cajaputi could attributed<br />

to low decomposition rate in swamp soil.<br />
