Comparison of chemical composition small diameter wild Leucaena leucocephala and Acacia mangium.

Leucaena leucocephala and Acacia mangium are listed among of the fast growing species that are wide used in Malaysia as livestock forage and industrial production. Thus, study was conducted to identify the chemical composition of small diameter wild Leucaena leucocephala with Acacia mangium and to compare between of them. Leucaena leucocephala (diameter 5-8cm) was collected at area Grik to Lenggong, Perak meanwhile Acacia mangium at area Jeli. The stem has been processed to three portions (bottom, middle and top) into small particle form for the chemical composition analysis. The method of chemical composition, sampling and preparation of the sample for analyzed of extractive, holocellulose, cellulose and lignin were carried out according to the Technical Association of the Pulp and Paper Industry Standard (TAPPI) except hemicelluloses, because the data was collected by using equation. The data that was collected are analyzed by using analysis of variance (ANOVA). The result shows that, there are not significant different for the comparison between species but the result shows the different significant for dependent of extractive and lignin variable (p<0.05 and P< 0.01) in comparison between three different portion.
