  • The total population of Indonesia in 2003 is 216,708,030 people (BPS), 52% of whom live in rural areas. If it is assumed that 80% uses biomass as fuel in the kitchen then the number of rural residents at risk of indoor pollution (PUDR) is 89,526,421 people. There are many types of biomass stoves on the market today, but currently still many biomass stoves have a high CO emission. One of these is biomass stove UB – 03 which still have deficiencies. The first phase of the research on biomass stoves UB-03, has managed to correct the temperature of the primary combustion (Rian, 2016). So that the resulting temperatures are higher than the previous stoves. To reduce the carbon monoxide (CO) content produced by the UB-03 biomass stove, the hole modification and the addition of fins to the secondary combustion of the stove were made. Analyze using MATLAB (Matrix Laboratory) to determine which changes are more significant or more perfect on the stove. From the results of experiments that have been done, the longest combustion duration is 29 minutes and 50 seconds with the highest temperature of 770oC and average temperature 668oC. The design of secondary combustion that was done on the UB – 03 biomass stoves is A1 B3 C3. With the following changes, the reduction of air intake in the airway B which initially has 35 holes is then reduced to 19 holes and the addition of fins with a slope of 60o, while in air channel A the number of holes remains in accordance with the standard number. From the emission testing that has been done, the result of carbon monoxide exhaust gas is 5.8 ml on UB - 03 cooker that has not been done changes and carbon monoxide content of 3.6 ml on the modified stove.
