Abstract:
Energy management is an essential aspect of modern manufacturing operations, as it
can help organizations reduce costs, enhance efficiency, meet regulatory requirements,
and improve competitiveness. The current practice of monitoring the energy
consumption in many plastic manufacturing factories is through Specific Energy
Consumption (SEC). A finding in this study reveals that incorrect SEC values may lead
to invalid interpretations of energy efficiency, resulting in adverse effects on cost
optimization strategies. This study proposes a reliable method for assessing energy
consumption in a plastic manufacturing factory, highlighting the importance of
considering various metrics and indicators in addition to SEC for energy performance
evaluation. This study recommends further research to minimize energy waste and
emphasizes the importance of regularly reviewing and adjusting energy management
practices and targets to promote maximum energy savings. Moreover, the study
suggests regression analysis as a useful tool for predicting future energy consumption
and can serve as a better indicator than SEC values in certain cases.
