Abstract

The manufacturing sector in Batam faces increasing pressure from rising energy costs and operational inefficiencies. This study investigates how integrating risk management frameworks, specifically ISO 31000 and FMEA, can enhance energy efficiency in manufacturing operations. A mixed-methods approach was employed, combining quantitative analysis of energy consumption data from selected firms with qualitative insights from interviews with key industrial stakeholders. Baseline energy performance was established, and operational risks were assessed and prioritized. Findings show that outdated machinery, poor maintenance, and unplanned downtimes significantly contributed to energy inefficiency. Implementation of risk-based interventions led to measurable improvements in energy use and cost reduction. Firms adopting the integrated approach reported that 15% energy saving in PT X results in operational cost savings of $ 29.994, and 10% energy saving in PT Y results in operational cost savings of $ 23.952. The Return on Investment (ROI) from implementing an integrated energy risk management strategy is estimated to reach 18 months to 20 months, based on reduced energy consumption and increased productivity. The study underscores the importance of tailored risk-energy frameworks in industrial settings and suggests avenues for future research in broader contexts.

Abstract

Steam power plants are among the primary sources of electricity generation; however, they face significant challenges in terms of energy efficiency and environmental impact due to their high consumption of coal. Innovative strategies are required to reduce emissions and improve system efficiency. One potential approach is the reutilization of condenser cooling water to drive a hydropower turbine before being discharged into the sea. By harnessing the head and flow rate of this water, the kinetic energy from the waste stream can be converted into additional electricity. This study examines a process engineering approach to integrating a hydropower generation system with a steam power plant, encompassing technical analysis, energy efficiency, as well as economic and environmental impacts. Simulation results indicate that the system is capable of generating between 14.2 and 49.5 kW of power, depending on operating conditions and water availability. The electricity produced can be utilized for internal Steam power plant needs, such as cooling pumps and lighting, thereby reducing dependence on coal combustion. This strategy not only improves energy efficiency and reduces operational costs but also supports environmental conservation and the long-term sustainability of power plant operations.
