Abstract
Timor Island has a good source of “lamtoro" (Leucaena leucocephala) energy forests. Although “lamtoro” has been used for the substitution of coal within the co-firing control plant on Timor Island, there is no empirical data on the carbon content, calorific, and economic values generated from the biomass. This study aims to investigate the potential for "Lamtoro" woodlands to produce renewable biomass. The proximate, ultimate, and chlorine techniques have been used to analyze carbon content and calorific values. While the economic value added (EVA) tools of analysis have been used to analyze the economic value of biomass. The result of the study shows that the calorific value (HHV—higher heating value) of the coal and biomass blend with a proportion of 95%:5% is 4,342 kcal kg⁻¹, almost equivalent to the highest calorific value of coal. The commercialization of biomass created from “lamtoro" is financially viable, as evidenced by the company's financial performance. Analysis of the financial performance included in the biomass generation commerce showed that each kilogram of "lamtoro" biomass contributes IDR133.23 (18%) to the final product's value, indicating positive business prospects. Based on this result, the government should implement a policy to develop and maintain the existing forest as a source of bioenergy.
