Abstract

A burner is a tool used to heat the heater as a source of initial heat whose heat functions to drive the Stirling engine. The burner used in this test is self-designed. The purpose of this study was to determine the temperature profile, fuel consumption used, power on the burner, and the efficiency of the Stirling engine burner with variations in air flow rates. Variations in the airflow rate used in this study were 2 m/s, 2.5 m/s, and 3 m/s. This research method was carried out experimentally and analyzed by the water boiling test method. The results of the three variations of air flow rate show that the highest temperature occurs in the Stirling engine burner with an airflow rate of 3 m/s of 813,815℃, for fuel consumption with variations in air flow rate of 343 gr, Stirling engine burner power with variations in air flow rate 2 m/s, 2.5 m/s, and 3 m/s produce the same power of 4.48 kW, and the highest efficiency on the Stirling engine burner is obtained at an airflow rate of 3 m/s of 38.33%.

Abstract

The slicing process of shallots using simple tools remains a major obstacle to increasing production capacity and efficiency in the processing industry. To address these limitations, an analysis of the blade count variation in shallot slicing machines is required to produce more efficient and uniform slices. This study aims to optimize the shallot slicing process, enhance production efficiency, and evaluate machine performance with blade count variations of 2, 3, and 4 blades.The methods employed include documentation, direct experimental observation, and systematic data collection through treatment of experimental variables. The results show that the use of 2, 3, and 4 blades yields slicing capacities of 62 kg/hour, 70 kg/hour, and 78 kg/hour, respectively, with an average slice thickness ranging from 0.8 to 1.1 mm.These findings indicate that the number of blades significantly affects slicing productivity and efficiency, with the 4-blade configuration demonstrating the best performance. This study provides valuable insights for developing more effective and efficient shallot slicing machines, contributing to increased productivity in the shallot processing industry.
