Comparative Study of Induction Motor and Steam Turbine at Kebon Agung Sugar Factory Malang Indonesia

Abstract

Induction motors and steam turbines are the main components in the sugar cane milling process. This study analyzes the efficiency of induction motors and steam turbines as mill drives at the Kebon Agung Sugar Factory in Malang, Indonesia. This study used experimental methods by observing and testing at the Kebon Agung Sugar Factory. The induction motors analyzed were mills 1, 2, and 5. Meanwhile, the steam turbines analyzed were cane cutter 1, 2, heavy-duty hammer shredder, mill 3, and mill 4. Motor and turbine data were obtained through the control system. Furthermore, the motor and turbine data are processed, and the efficiency comparison is calculated. From the results of the analysis, the average value of the efficiency of an induction motor is more significant when compared to a steam turbine. The average weight of induction motor efficiency is 94.6%, and the average value of steam turbine efficiency is 77.2%. This research recommends that the Kebon Agung Sugar Factory replace the steam turbine with an induction motor in the future. The recommendation given to Kebon Agung Sugar Factory is the use of induction motors on CC 1, CC 2, HDHS, mill 1, and mill 5. An induction motor is a relatively easy install compared to a steam turbine; the construction is robust and highly efficient, requires minimal maintenance, and does not require special equipment during operation.
