Abstract
The small scale gold mining might produces waste material derived from the mining and the amagamation processes. This waste needs to be handled so as not to have a negative impat on the environment. Besides, the utilization of it would be hoped to give benefit for living, not to harm the life. Based on problems, this research was aimed to grow sweet sorghum on the contaminated soil and waste material as raw material for bioethanol production. Research was carried out by collecting soil samples and materials at mining or alteration sites (two soil samples), amalgamated solid waste (one solid material samples), soil affected by amalgamated wastewater stream (seven samples), and nonimpacted soil as control. The result of this study indicated that sweet sorghum plants might grow well in the media in the form of waste materials, and contaminated soil gives relatively the same results as those in the rice field and uncontaminated garden soil. The juice that was produced from sweet sorghum stem had enough sugar content for bioethanol production using fermentation technique. Keywords: soil, gold mining, sweet sorghum, bioethanol
