From the data above, it may be deduced that. The pulp preparation using acid under appropriate conditions in this study. There is a relatively low cost. And efficiency in the production of organic solvents significantly. This study It was concluded that raw cassava (Cassava materials) can be used as an alternative raw material in the production of organic-soluble one. Which can produce organic solvent than 19 g / L just a little preparation before entering the composting process only.
