Abstract

The purpose of this study is to analyze the potential for energy savings because the laundry industry consumes a lot of energy and water. If the laundry industries are not controlled, it will cause serious environmental and energy problems. The audit activity was divided into three stages. Pre-audit stage, the auditors were divided into groups with clear details of tasks and responsibilities, starting with conducting energy audits on the floor, analyzing statistical data, and process flow. Site audit stage; conduct an audit on the floor from the beginning to the end of the process, then collecting and confirming the statistical data for energy and production. Post-audit stage, complete the audit report that will be submitted or presented to the laundry management, which consists of; audit findings with loss or savings analysis, accompanied by recommendations for further improvement. The results show that there are many savings opportunities, especially by overcoming the energy wasted in the production process. Improvements can be made by overcoming energy waste and controlling energy consumption and production more efficiently, implementing renewable energy technology such as solar dryer and hybrid photovoltaic and thermal (PVT) collector, and then considering industrial revolution 4.0 with IoT and ICT.
