Rice Husk Waste: Impact on Environmental Health and Potential as Biogas

Indonesia is an agricultural country with dry-milled grain production reaching 55.6 million tons in 2022. Besides producing abundance of rice, milled dry rice also results waste the form husks. The handling husk mostly by burning. smoke from burning toxic, so it has a poor impact on environmental health. This study regarding effect improper management husks health, utilization biogas energy, and its potential Indonesia. Air quality measurement areas parameters SO2, CO, NO2, PM10 method Indonesian National Standard. Then anaerobic laboratory-scale research to convert into biogas. Chemical pretreatment was carried out 3% NaOH C/N ratio determined 25. Condition variations were for L-AD 7% TS SS-AD 17% TS. We found that harm It indicated SO2 exceeding standards, namely 167 132 µg/m3.The NO2 parameter almost reached standard, 178 µg/m3. Generated can be converted renewable energy good productivity conditions, 75.2 mL.gTS-1. Biogas 1.5 liters. support security
