Abstract

One of the uses of used oil is as fuel for multifuel stoves. A multifuel stove is a stove that has flexibility in its fuel selection. In the operation of a multifuel stove, the air supply plays an important role in the combustion process. This study discusses the influence of air velocity on fire characteristics and water temperature during the heating process. In this study, three variations of air velocity were used, namely 13 m/s, 12 m/s, and 11 m/s. Based on the tests that have been carried out, it was found that the speed of air blown into the combustion chamber can affect the temperature and duration of the flame. The faster the speed of air that is blown into the combustion chamber, the higher the temperature of the flame will be, but the faster the fire will be extinguished. This is because more oxygen is supplied into the combustion chamber, causing the combustion process to take place more quickly and intensely. Meanwhile, regarding the water heating time, the time required by the three variations of air speed to heat 0.5 kg of water to boiling is 1.5–2 minutes, which surpasses the performance of gas stoves and conventional electric stoves.

Abstract

Sago is a local food resource with high potential to be developed as an alternative carbohydrate source in Indonesia. One of the critical stages in sago processing is the grating process, which significantly affects production capacity and efficiency. This study aims to analyze the effect of the number of grating teeth on the performance of a sago stem grating machine. Two grating tooth variations, namely 18 × 20 and 20 × 22, were tested using a 7.5 HP gasoline engine. Each variation was tested three times using sago stems weighing 6,000 grams. The observed parameters included grating time, mass of perfectly grated material, imperfect grated material, wasted material, production capacity, and production efficiency. The results showed that the 20 × 22 grating teeth variation produced better performance, with a production capacity of 128.85 kg/h and an efficiency of 94.70%, compared to the 18 × 20 variation with a capacity of 99.65 kg/h and an efficiency of 89.3%. The study concludes that increasing the number of grating teeth significantly improves the performance of the sago stem grating machine.
