Abstract

Nowadays the need for fuel has always improved as following the increase in community and industry activities. Therefore, we need to search for resources of alternative energy. The tobacco rod is one of the lignocellulosic materials which has three main components namely cellulose, hemicellulose and lignin. The production of bioethanol from lignocellulosic materials is strongly influenced by the composition of cellulose in its raw materials. This research use  the cellulose extraction of tobacco rods by a bases method on NaOH concentrations are 2.5%, 5%, 7.5%, 10% and 12.5% (v/v) . The results show that the concentration of NaOH strongly influences the yield of cellulose extracted. The highest cellulose yield of the extraction is obtained on 12.5% of NaOH concentration.Keywords:Extraction, cellulose, tobacco rod, bioethanol

Abstract

Moringa (Moringa oleifera L.) is a plant belonging to the moringaceae family. Moringa seeds contain oil which can be used as a raw material for making azelaic acid. Azelaic acid is used as an anti-acne in the pharmaceutical and cosmetic industries. Azelaic acid can be obtained from the oxidation process of fatty acids in moringa seed oil using potassium permanganate as an oxidizing agent. The resulting azelaic acid is in the form of white crystals with a conversion percentage of 72.17%. The results of the FT-IR characterization showed the formation of azelaic acid characterized by widening of the hydroxyl group at 3448.46 cm-1 followed by a shift of the ester group at absorption of 1633.46 cm-1. The ester bond is strengthened at a wavelength of 1115.95 cm-1.
