Bioethanol is an alternative and potential fuel derived from plants, which has the ability to reduce CO2 emissions. It contains sugar that can be utilized and processed into bioethanol. This study aims to produce bioethanol from pineapple peel (Ananas comosus Merr.) through acidic hydrolysis and fermentation process using Sacharomyces cereviceae. This research was expected to know the optimum condition of S. Cereviceae mass and the time of fermentation on the conversion of pineapple peel into bioethanol towards amount and content of ethanol produced. The hydrolysis was using sulfuric acid (H2SO4), fermented with variations yeast 20, 40 and 60 gram and 2, 4 and 6 days of time variations. The resulting bioethanol was purified using a distillation process, then analyzed by gas chromatography. The results showed that optimum ethanol content was obtain in yeasts 20 and 40 grams and 2 days of fermentation. The resulting ethanol content was 26.3% and 24.6%.

This study studied the best levels of bioethanol from a combination of cassava peel and pineapple peel mixtures with 6 gram yeast mass and 72 hours, 96 hours and 120 hours fermentation time, to determine the optimal fermentation time and find ethanol levels according to SNI. This research was carried out by hydrolysis or cassava peel and pineapple peel using aquades for 30 minute to break the molecule into two parts, then carried out the fermentation process using Saccharomyces Cerevisae (yeast) and the distillation process using a destilator to obtain ethanol for fermentation then tested with a Refractometer to determine whether there is an ethanol level formed from the distillation process. The best sample selected was then tested for ethanol content using the Gas Chromatography tool. The results of this study are known by using the Gas Chromatography tool to determine the ethanol content contained in the distilled sample, the highest ethanol content of each combination. So that the best ethanol yield from a combination of 100% cassava peel - 0% Pineapple Peel with a duration of 120 hours fermentation producing ethanol of 89.81% is still not included in the SNI category.

This paper has aimed at evaluating the concentration of bioethanol obtained using sunflower stem as natural support, molasses as carbon source and Saccharomyces cerevisiae yeast in a continuous flow reactor. The natural support was tested to investigate the immobilization/growth of S. cerevisiae yeast. The concentration of bioethanol produced by fermentation was analyzed by gas chromatography using two methods: aqueous solutions and extraction in organic phase. The CO2 flow obtained during the fermentation process was considered to estimate when the yeast was deactivated. The laboratory experiments have highlighted that the use of plant-based wastes to bioconversion in ethanol could be a non-pollutant and sustainable alternative.
