Bioethanol Production from Breadnut (Artocarpus Camansi) Rind Waste as a Sustainable Energy Source

Abstract Global energy consumption of fossil fuels which is expected to rise by about 177 quadrillion British thermal units (BTU). The scarcity oil and along with the demand for needs can be overcome switching renewable environmentally friendly energy. Biofuels an alternative provide a clean green environment. Breadfruit peel waste high in carbohydrates sugar so have potential optimized into bioethanol. This research aims determine effect variations yeast mass fermentation time on bioethanol content breadfruit rind through distillation process. study applies method (PI: 8 grams 72 hours), (P2: 10 (P3: 96 (P4: hours). Then, ethanol was tested Perkin Elmer Clarus 580 (GC) HS Turbo Matrix 40 (headspace sampler). optimum results were found variation hours, resulting 339.8 mg/L at simplo 338.08 duplication or average 338.94 mg/L.
