The utilization of biomass energy, particularly from bio-pellet teak sawdust, is gaining attention as a renewable alternative to fossil fuels due to its environmental benefits. This study investigates the performance of a Top-Lit Up Draft (TLUD) stove fueled by bio-pellet teak sawdust based on SNI 7926:2013, focusing on the effects of airflow velocity and secondary air hole design on thermal efficiency, specific fuel consumption (SFC), and emissions (CO and CO₂). Experiments were conducted at Politeknik Negeri Sriwijaya from March to July 2025 using a Full Factorial Design (FFD). Results showed that the factory design achieved the highest thermal efficiency of 62.14% and the lowest SFC of 0.520 kg/h at 5 m/s. The modified design reached a peak thermal efficiency of 53.90% and an SFC of 0.558 kg/h at 4 m/s. The factory design also exhibited better CO and CO₂ emissions performance. These findings suggest that while modifying air holes showed minimal improvement, further research suggest to test modified hole design in other stove types to know the effect of enhance combustion efficiency and reduce emissions.
