Abstract

Waste management and processing that is not optimal causes accumulation of waste every day. In addition, processing waste, especially plantation or agricultural waste that only becomes fertilizer or compost, will be very unfortunate. Cellulose waste can actually be used to create second generation bioethanol. With the use of as much as 20 grams of starting material, and a preliminary process such as delignification, it is intended that the lignin content in each material can be damaged and later the cellulose compound can be processed into glucose. Combination of treatments and materials such as corn cobs, skin of kluwek , used hvs paper, and used newsprint; NaOH liquid in the delignification process for 4 hours at 50 ° C; use of cellulose solution in the hydrolysis process for 4 hours at 50 ° C; variations in the addition of a solution of 10 ml v/v, & 20 ml v/v; variations long fermentation time 5 days, 10 days 15 days; and the distillation process is intended so that researchers get the highest alcohol content in the material and process being carried out. The best results were obtained on hvs paper material which was delignified first, and with the addition of a starter solution of 20 ml v/v, and fermentation time of 10 days with an alcohol content of 23.78%. Keywords: second generation bioethanol, delignification, fermentation

Abstract

Air pollution does not only occur outside the room but also indoors. One of the most common indoor pollutants is Carbon Monoxide (CO) and Nitrogen Oxide (NOx). Incomplete combustion smoke accumulates in the room as a result of cigarette consumption. Pollutant reduction can be done by means of adsorption, this research utilizes capsule and charcoal non-use cigarette filter waste from cigarette filter-producing factories that do not pass the quality test to be used as activated carbon which will be used as CO and NOx adsorbents in cigarette smoke. After carbonization, the cigarette filter was activated with a KOH solution of 65% using an activator agent and solution ratio of 4: 1. This study used a reactor that was modeled like a room with a space volume of 0.02 m2. Activated carbon made from FR-Capule and FR-Charcoal is proven to be able to reduce CO levels by 86.8% in a contact time of 120 minutes and NOx 89.7% within 30 minutes of contact time on sidestream smoke, and the CO content drops by 98.8% while NOx decreased by 100% at 30 minutes of contact time on mainstream smoke.
