Indonesia has great potential in utilizing biomass as a renewable energy source, especially for household needs. Biomass gasification stoves can increase energy efficiency while being environmentally friendly. This study analyzes the effect of air flow rate variations on the performance of biomass gasification stoves fueled by a mixture of rice husk and sawdust biopellets. The experimental method uses variations in air flow rates of 3 m/s, 4 m/s, 5 m/s, 6 m/s, and 7 m/s with the Water Boiling Test (WBT) tool to measure parameters such as flame temperature, CO and CO2 emissions, thermal efficiency, Specific Fuel Consumption (SFC), and combustion efficiency. The results showed that an air flow rate of 6 m/s produced optimal performance with the highest flame temperature (786°C), maximum thermal efficiency (61.80%), and lowest CO emissions (20 ppm). Combustion efficiency reached 94.38% with the lowest SFC (0.53 kg/h). Meanwhile, the flow rate of 3 m/s had a lower thermal efficiency (44.04%). This study concludes that the regulation of air flow rate is very important to achieve efficient and environmentally friendly biomass combustion, thus making a significant contribution to the development of renewable energy technology, especially biomass stoves.
