| dc.description.abstract | In this paper, an attempt was made to find out the diversity, productivity and suitability of plant species in
the secondary forests of East Kalimantan, Indonesia which has the potential to be used as high-quality
feedstock for sustainable green energy production. Diversity of plant species was studied by making 22
plots with the size of 20 m x 20 m located at secondary forest of Mahakam Ulu, East Kalimantan, Indonesia.
The importance value index of plant species found was calculated using the equation of Mueller-Dombois
and Ellenberg. The physico-chemical properties and elemental composition of wood biomass collected
were determined using the method of American Standart for Testing and Material (ASTM). We found 57
species which belongs of 28 families were growing in the secondary forest area. Among them, the highest
Important Value Index (IVI) was Lamiacea, Vitex pinnata (32.72%). V. pinnata was also achieved the highest
calorific value of 18.00 MJ kg-1. Due to suitable energy properties, growth rate and also adaptability of the
woody biomass, a secondary forest plant species, V. pinnata was recognized as the important species among
all other species observed because of its high adaptability and energy content. | en_US |
