Abstract: Bulrush is a plant that is available abundantly however it has not been utilized well. During this time, it was utilized just as animal feedstock, even it is considered as weeds. Bulrush has cellulose, glucose, and starch content that can be used as material of ethanol production. This research was aimed to review hydrolysis process, fermentation process, batch distillation process, and search for alternative material for bioethanol production. In bioethanol making process, three processes were done such hydrolysis process biologically by using enzyme and chemically by using HCl.While fermentation process used Saccharomyces Cerevisiae and batch distillation. After those three processes were done, high level of bioethanol content was obtained in 95%-96% and it could be concluded that bulrush can be used as alternative material of bioethanol production

Abstract: Multi-soil-layering (MSL) systems consist of soil mixture layers (SML) such as charcoal, sawdust, iron scraps, volcanic soil with composition (10:10:5:75) and permeable zeolite layers (PL) were constructed in 50 cm (width) × 15 cm (depth) × 50 cm (height) an acrylic box like the brick pattern for removal of phosphate, nitrite, nitrate, oil and grease from noodle industry wastewater. The variations of the wastewater flow rate in the system were 10, 20, 40, and 80 mL min-1 with two processes aeration and non-aeration conditions were evaluated. The results revealed that the aeration assists the removal efficiency of phosphate, nitrite, nitrate, oil and grease on MSL system at flow rate 10 mLmin-1 were 99.43%, 83.65%, 79.43% and 100%, respectively
