Bioethanol is an innovative solution that is environmentally friendly and able to reduce pollution by agricultural wastes. It has high oxygen content and burns more completely than gasoline. The research was aimed to utilize coffee wastes for producing a value added products and to reduce environmental pollution burden as well as to evaluate the potential for bioethanol production at probable optimum conditions using Saccharomyces cerevisiae. This process allows a yield of 77.29 % of bioethanol with respect to the theoretical value, which can be a viable alternative for obtaining second-generation biofuels in rural areas and for coffee smallholder plantation. The bioethanol production cost was assessed from waste coffee processing. In substantial amounts therefore, coffee pulp can be utilized as a potential raw material in bioethanol production in Ijen plateau region of East Java.. Bioethanol production cost was IDR 6 000 · L – 1 or USD 0.48 · L –1 . Based on these facts, compared to food crops coffee pulp which is an agricultural waste is a promising alternative feedstock for second generation bioethanol production.
