Berkurangnya sumber energi yang tersedia di Indonesia dikarnakan kebutuhan energi setiap tahun mengalami peningkatan yang cukup signifikan. Mengakibatkan penggunaan bahan bakar minyak yang berasal dari fosil saat ini masih menjadi kebutuhan utama di Indonesia. Padahal bahan bakar minyak berbahan baku fosil merupakan sumber energi non renewable (tidak terbarukan) yang lambat laun akan habis.Penelitian ini dilaksanakan di Laboraturium Teknik Sistem Termal dan Energi Terbarukan, Fakultas Pertanian Universitas Jenderal Soedirman. Pengambilan data penelitian ini akan dilaksanakan pada bulan Agustus 2022 sampai Februari 2023. Penelitian ini menggunakan Rancang Acak Lengkap (RAL) dengan dua faktor yaitu konsentrasi mikroba Saccharomyces cerevisiae   0%, 5%, 7,5%, 10% dan lama fermentasi 3 hari, 5 hari, 7 hari. Masing-masing perlakuan diulang sebanyak 3 kali sehingga terdapat 36 unit percobaan. Variabel yang diamati kadar gula reduksi, kadar bioetanol, dan rendemen bioetanol. penelitian ini dengan tujuan mengetahui kadar etanol yang dihasilkan dari tongkol jagung manis dan pengaruh konsentrasi bakteri Saccharomyses cerevisiae dalam memproduksi bioetanol dari tongkol jagung manis secara ditumbuk.Hasil analisis bioetanol dari tongkol jagung manis menunjukan bahwa kadar air yang dihasilkan sebesar 7,4% dan kadar gula 2,1 m/v. Lama waktu fermentasi berpengaruh nyata terhadap kadar bioetanol dimana kadar bioetanol optimal didapatkan pada perlakuan waktu fermentasi 7 hari tertinggi yaitu 0,753% m/v (S3T3).

The reduction in available energy sources in Indonesia is because energy demand increases significantly every year. As a result, the use of fuel oil derived from fossils is still a major need in Indonesia. Even though fuel oil made from fossil fuels is a non-renewable energy source that will eventually run out. This research was conducted at the Laboratory of Thermal System Engineering and Renewable Energy, Faculty of Agriculture, Jenderal Soedirman University. Data collection for this study will be carried out from August 2022 to February 2023. This study used a Completely Randomized Design (CRD) with two factors, the concentration of the microbial Saccharomyces cerevisiae 0%, 5%, 7.5%, 10%, and 3 days of fermentation, 5 days 7 days. Each treatment was repeated 3 times so that there were 36 experimental units. The observed variables were reducing sugar levels, bioethanol levels, and bioethanol yield. This study aims to determine the ethanol content produced from sweet corn cobs and the effect of the concentration of Saccharomyces cerevisiae bacteria in producing bioethanol from ground sweet corn cobs. The results of bioethanol analysis from sweet corn cobs showed that the resulting water content was 7.4% and the sugar content was 2.1 m/v. The length of time of fermentation has a significant effect on the levels of bioethanol where the optimal level of bioethanol is found in the highest 7-day fermentation time of 0.753% m/v (S3T3).
