Abstract

Production of second generation bioethanol research from waste tobacco stalks and flowers can be concluded that the waste stalks and stems of tobacco could potentially be used as an alternative raw material production of second generation bioethanol. Second generation bioethanol production process from waste tobacco stem and stalk begins with the drying process materials, raw material reduction, delignification, hydrolysis and fermentation, then topped with a distillation process to produce ethanol. In the process of acid hydrolysis of waste tobacco stalks and flowers are made ​​using H2SO4 2 M, 2,5 M and 3 M produce glucose at 6.8%, 8% and 9.2%. Later in the fermentation process of the waste stalks and flowers of tobacco use Sacharomyces cerevisae bacteria can produce ethanol content of 0.61% at a concentration of 2 M, 0.75% at concentrations of 2.5 M and 0.81% at a concentration of 3 M.
