In this paper, efficient production of ethanol from corn by using fermentation process is discussed. A mathematical model is developed for the above-mentioned process and the challenges in adjusting the specific growth rate(μmax) has been addressed. Also, the rate or velocity of growth of the microbial cells which is the key affecting factor of the substrate concentration is adjusted for optimum results. On successful design of the mathematical model, the concentration of ethanol is controlled by using four different controllers out of which one suitable controller is considered as the ideal controller for the production of ethanol from corn

This study aims to determine the phytochemical components of different extracts of Cinnamomum burmanii B. from different regions in Indonesia by GC-MS using ethanol, distilled water and isopropyl alcohol as solvents. The analysis showed that the ethanol extract of cinnamon from the Aceh region, which contains five compounds with biological activity and the main compound was 59.77% coumarone. Meanwhile, the distilled water extract contains four compounds with biological activity, and the main chemical compound was 37.01% coumarin. For the extract of isopropyl alcohol, contains four compounds with biological activity and the main compound was coumarin at 41.55%. The ethanol extract of cinnamon from Jambi region contains three compounds with its biological activity and the main compound was coumarin at 28.31%, while the extract using distilled water contains four compounds with biological activity and the main compound was 1-phenyl-4- carboxy-4,5 at 33.50%. Furthermore, for the isopropyl alcohol extract, there are five compounds with biological activity, and the most important chemical compound was 2-propanol at 45.89%. Meanwhile, the ethanol extract of cinnamon from West Sumatra contains six compounds that were identified as biological activity and the main compound was 2-propanol at 14.97%, while the distilled water extract contains four compounds with biological activity and the main compound was 17.49% for 1-phenyl -4-carboxy-4,5. For the extract of isopropyl alcohol, four compounds with biological activity were obtained, and the main compound was 9.96% coumarin. This study confirms the existence of different bioactive compounds and biological activities in each original region of cinnamon in Indonesia.
