Abstract
Although the used of fossil fuels are high volume and they are become the dominant energy
resource for the modern world. But they are not enough and they are non-renewable resources. So
that a global movement toward the generation alcohol of renewable energy is therefore under way
to help meet increased energy needs. Alcohol has been used as a fuel for along time in the past. It
was obtained from biological sources. It can produce from cellulose which is known as cellulosic
alcohol. In this project, considering of waste paper which consists of mostly cellulose is made up of
sugar for fermentation and converted to ethanol.The waste paper was digested with cellulose
enzyme from Aspergillus Niger and broken down to sugar. After this digestion process, ethanol
was produced by yeast (Saccharomyces Cerevislae.) fermentation of sugar. The result was shown
that 1,875 grams of waste paper and 1,500 mL of cellulose enzyme in 150 L within 7 days of
digestion process and 2 days of yeast fermentation were obtained 10 % v/v ethanol. After that most
of water was removed by distillation process and got 7 L of 65.08 % v/v ethanol
