Pembuatan Bioetanol Dari Mikroalga Limbah Cair Kelapa Sawit Dengan Variasi Rasio Massa Mikroalga Dan Volume H2so4, Konsentrasi Ragi Dan Waktu Fermentasi Menggunakan Saccharomyces Cerevisiae

---

Energy consumption is increasing steadily with the population growth and industrial development. Therefore, a substitute should be found. Bioethanol has been pointed out as a solution for variety complex problems related to energy and environmental issues. One of material that has potential to be used as raw material for bioethanol is microalgae. Microalgae Chlorella pyrenoidosa can be lived in wastewater, such as in palm oil mill effluent. Chlorella pyrenoidosa has been considered to be aviable and renewable feedstock for bioethanol production because it high carbohydrates contain. Chlorella pyrenoidosa is hydrolyzed into glucose for further fermented into bioethanol. This research aimed to observe the best condition on hydrolysis and fermentation process by varying ratio mass of microalgae with volume of H2SO4 are 1:8; 1:10 and 1:12, concentration of yeast are 10%, 15%, 20% and 25% and fermentation time are 3, 5, and 7 days. Measurement of bioethanol concentration using refractometer. The analysis show that highest concentration of glucose was 1,57 mg/ml at ratio 1:12 and the highest concentration of bioethanol was 0,28% using yeast 25% within 3 days. Keywords : Microalgae Chlorella pyrenoidosa, hydrolysis, fermentation, bioethanol
