Abstract
Onggok is a residue from processing cassava into tapioca flour and it used for animal feed, mosquito coil, and sauces. The best price of onggok is around Rp. 1800/kg for white color specifications, 12% maximum moisture content and it is free from foreign material such as sand or gravel. In fact, most of farmers using traditional drying and it does not produce onggok with low quality, low capacity, and long time necessary. Drying capacity obtained in these conditions is 6-8 Tons / month.Most of onggok farmer in Lampung province do not use a dryer to reduce moisture content of onggok from 60-70% to 10-12% due to large operating costs and the dryers are expensive, so they turn to drying in the field. This onggok resulted are only sold at a price Rp.650-/kg and impact to low welfare of onggok farmers.Bio-dryer is a combination between rotary dryer and gasifier biomass with high dryer capacity and economic. Optimum performance of bio-dryer are at: moisture content of onggok feed is 30-40%, gasification airflow 0.011 kg / s, biodryer rotation 20 rpm, and drying mass are 10-12 kg in single process. The maximum reduction of moisture which is about 20% and drying capacity gained from this condition is 480 kg /day or 12 Tons per month. Quality of dry onggok produced under these conditions approached onggok best quality with the selling price reached Rp.1400–Rp.1600/kg.
