Utilization of clay as a briquette stove often results are not satisfactory as is the use of other fuel stoves, this is because the amount of air in the furnace burning chamber has not been determined and focused properly, so the purpose of this study is to determine the thermal efficiency of the furnace at variations in the diameter of the aluminum sleeve in the furnace burning chamber. The method used is to test 5 variations in diameter of the furnace burning chamber (cylinder). The results showed the best thermal efficiency was obtained at 52.87% at 180 mm slab diameter, boiling time at 9 minutes, with a heat loss of only 2.02 kW. ## Keywords - Briquette - Stove - Materials science - Waste management - Solid fuel - Slab - Boiling - Environmental science - Thermal efficiency - Coal - Nuclear engineering - Pulp and paper industry - Combustion - Engineering - Chemistry - Structural engineering - Organic chemistry --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
