Baglog sterilization is a crucial step in the oyster mushroom cultivation process to ensure that the growing medium is free from microbial contamination. This study aims to determine the effect of baglog quantity on the thermal efficiency of the steamer during the sterilization process. The number of baglog used varied at 5, 7, 10, and 14 units. The observed parameters included thermal efficiency, specific fuel consumption (SFC), and sterilization temperature. The results showed that increasing the number of baglogs is directly proportional to the increase in thermal efficiency and the decrease in sterilization temperature. The highest thermal efficiency of 6.49% was achieved with 14 baglog at the lowest sterilization temperature of 111°C, while the lowest efficiency of 3.10% occurred with 5 baglog at 135°C. SFC values also decreased as the number of baglog increased, from 0.0006278 kg/kJ at 5 baglog to 0.0003002 kg/kJ at 14 baglog. The decrease in SFC and temperature indicates that heat utilization becomes more optimal with a higher number of baglogs. Therefore, increasing the number of baglogs during sterilization can significantly improve the thermal efficiency of the steamer.
