Abstract

Bioethanol is one alternative to fossil fuel substitutes depleting annually. Bioethanol production using waste material containing cellulose such as rice straw, require special attention in the process of pretreatment to customize the lignocellulose both in terms of structure and size to break up and reduce the content of lignin and hemicellulose. This research has been conducted on the hydrolysis of rice straw using wet milling pretreatment (WMP) and microwave-NaOH method compared to the dry milling pretreatment (DMP) with respect to the content of cellulose, hemicellulose and lignin. The results showed that the hydrolysis using WMP has a lower content of cellulose, hemicellulose and lignin compared to the DMP, since the size of the rice straw affect the mesh lignocellulose content. The larger mesh size of rice straw used, so the lignocellulose content is getting smaller.   Keywords: Bioetanol, Delignifikasi, Pretreatment, Wet Milling, Rice Straw
