Abstract

The imbalance between supply and fuel needs led to the impact of the energy crisis. Bioethanol is an alternative fuel that has the potential to replace fossil fuels. Bioethanol is the result of fermentation of biomass ethanol with the aid of microorganisms. This study aims to determine the ethanol content is influenced by the concentration of the solution of sugar molasses, as well as determine how much sugar concentration in the most optimal fermentation of molasses (molasses). The fermentation process varied with the concentration of 12%, 14%, 16%, 18%, 19% and 20%. To determine levels of ethanol produced, then the measurement or test the ethanol content in each variable concentrations of sugar substrate by means of pycnometer. The results showed that the concentration of the solution of sugar molasses effect on levels of ethanol produced. The highest ethanol content obtained at a concentration of 18% sugar, amounting to 13.85%. Lowest ethanol content obtained at a concentration of 12% sugar, namely 4.56%, while the sugar concentration of 14% - 18% ethanol continues to increase in a row to 6.4%, 12%, and 13.85%. Cereviseae Saccharomyces fermentation activity declined at a concentration of 19% sugar and 20%, ethanol is converted decreased to 11.82% and 8.07%.

Abstract

During this cooling fish handling is only done by fishermen because it is considered the most effective. But with the rise in fuel prices, the purchasing power of ice fishermen has become even more severe, so the need to find alternative ways of preserving fish that is inexpensive, easy to obtain and have a noticeable effect on the quality of fresh fish as well as safe for the preservation of fresh fish. Liquid smoke technology is an effective potential to help maintain the quality of fresh fish with coconut shell as raw materials. The purpose of this study was to obtain the optimum moisture content of the length of time drying the coconut shell into liquid smoke.This research used an experimental method with long time drying the coconut shell. This study begins with cleansing, enumeration, and drying coconut shell for 0 day, 1 day, 2 days, and 3 days. Then do the pyrolysis process until the process redestilasi and filtration column. Results of liquid smoke grade 3 and grade 1 was analyzed by GC-MS and LC-MS. Treatment on fresh fish is done using a variable length of time drying the coconut shell and the results conducted organoleptic tests include color, aroma, texture and taste.The result of this research is a long time optimal drying for 3 days, with a water content of 1.96%, 6.25% acid concentration, and pH value of 1.9. While the magnitude of the yield of 35.8% at 0 days

Abstract

The energy crisis of fuel is a problem faced by almost every state, predicted fuel reserves only enough oil to meet the world's needs for the next 30 years. Bioethanol is a non-fossil fuel considerable potential and can be used as an alternative fuel. This study aims to determine the effect of pH on ethanol yield and to determine the optimal pH by using a fermentation process raw material molasses. The research variables consisted of fixed and changing research, the materials used are, molasses (molasses), yeast Saccharomyces cerevisiae, NPK, urea, and water, and the tools used, the fermentor, pH meters, and pycnometer. The conclusion of this study, the pH affects the quality of ethanol and the highest levels of ethanol produced at pH 4.5, where the concentration of glucose and yeast performance Sacharomyces cereviseae very optimum at pH 4.5 to produce the ethanol content amounted to 5.6%.

Abstract

The increasing needs of people who are not balanced with fuel supplies at the national and world level are bringing about the impact of the energy crisis. The reliance only on renewable energy makes people have to look for alternative energy sources. Bioethanol is a type of fuel that can replace fuel. The bioethanol process is fermented from biomass material with the help of microorganisms. This study aims to know the performance of yeast composition in the fermentation process against ethanol quality. The ingredients used are molasses with a sugar content of 54% as much as 8 L. Molasses is mixed with NPK, Urea, and the yeast Saccharomyces Cerevisiae. Khamir's composition varies by 8, 12, 16, 20, 24, 28, and 32 grams. To test ethanol levels on each variable by measuring the difference in water density and ethanol using a pycnometer. This study's result is the highest ethanol quality obtained at a sugar concentration of 12 grams (0.2%), at 5.6%. The lowest ethanol quality is obtained at a sugar concentration of 32 grams (0.4%) i.e., 3.29%, while in yeast composition 8, 16, 20, 24, 28 grams of ethanol quality continued to decrease consecutively to 3.6%, 5.4%, 5.3%, 5.2%, and 5.1%.
