چکیده    Indonesia as the owner of the largest tropical waters could potentially become the largest producer of biofuels in the world. with an abundance of sunlight as a plant photosynthesis,the proliferation of marine life is much higher when compared with temperate regions. seaweed as one of the marine life which is scientifically known as algae or algae and chlorophyll is a plant containing approximately 35.6 to 58.3% carbohydrates in the form of a polysaccharide polymer in the form of fiber. the purpose of this study was to determine the conversion of cellulosic waste from seaweed that is the rest of the crop or seaweed damaged as the material for bioethanol production through the process of saccharification and fermentation simultaneously using bacteria clostridium thermocellum. the operating conditions are optimal for pretreatment with liquid hot water (lhw) method was obtained at a temperature of 121°c for 60 minutes and added a solution of buffer ph 7 in the fermentation process gained 2% ethanol fermentation time for 7 days. damage to the cell structure of seaweed analyzed by sem. as a result of treatment with lhwmethod makes the surface layer of waste lignocellulose from eucheuma cottonii the surface area of cellulose to become more open as a result of the loss of wax or lignin in microfibril.
