Dan nilai rata- rata berbahan stainless steel 304, T1 sebesar 748,6°C, T2 rata- rata sebesar 42,1°C, T3 rata- rata sebesar 334,5°C , dan nilai rata-rata T4 sebesar 316,3°C. Dengan pengujian selama 30 menit dengan pencatatan waktu T1 T2 selama persatu menit sekali, dan pencatatan T3 T4 selama perlima menit sekali untuk mengetahui perubahan suhu yang di dapat. The objectives of this study were: (1) To analyze the effect of heater wall material type on the temperature and air pressure produced by a Stirling engine. (2) To determine the effect of heater wall thickness on the temperature and pressure performance of the Stirling engine. (3) To identify the optimal combination of heater materials and wall thickness to achieve maximum temperature and air pressure. The method used was a qualitative one. The materials used were a 3kg gas cylinder and an air pump. The tools used were a heater, digital scale, flow meter, regulator, stick pipe, burner, stopwatch, thermometer, stainless steel NPT thermowell, thermocouple sensor cable, and a thermogun. The dimensions of the heater were SM5C carbon steel, with an inner diameter of 45 mm, an outer diameter of 55 mm, a cap diameter of 16 mm, a height of 90 mm, and a thickness of 4 mm. The heater dimensions are made of 304 stainless steel: an inner diameter of 45 mm, an outer diameter of 55 mm, a lid diameter of 16 mm, a height of 90 mm, and a thickness of 3 mm. For SM5C carbon steel, the average T1 is 720.8°C, the average T2 is 33.3°C, and the average T3 is 510.8°C. The average T4 is 406.8°C. For 304 stainless steel, the average T1 is 748.6°C, the average T2 is 42.1°C, the average T3 is 334.5°C, and the average T4 is 316.3°C. The test lasted 30 minutes, with T1 and T2 recorded every minute, and T3 and T4 every fifth minute to determine the temperature changes.
