Abstract

PT. PLN (Persero) ULPLTD Bagan Besar PLTD Bengkalis where the diesel engine is the prime mover. In this case, the role of engine maintenance is needed so that there are no obstacles in the process of distributing community power, especially for Bengkalis Island. Therefore, it is necessary to identify to measure the level of effectiveness of the work of the machine by using the Overall Equipment Effectiveness (OEE) method. Overall Equipment Effectiveness (OEE) is a method of measuring the overall effectiveness of a production machine that involves measuring the level of effectiveness of time, the level of machine performance, and the level of quality of products produced. Measuring the level of work effectiveness of the Caterpillar Type 3512B engine with the Overall Equipment Effectiveness (OEE) method at PT. PLN (Persero) ULPLTD Bagan Besar PLTD Bengkalis in the December 2018 - March 2019 period the results obtained do not meet the value of the Word Class Ideal OEE with a percentage value below 85%.

Abstract

Vibration arising from cyclic forces between coupled components can lead to performance degradation and mechanical damage. This study aims to analyze the effects of belt dimensions and installation configurations on the vibration characteristics of a belt-driven centrifugal pump for condition-monitoring applications. Vibration data were collected using an accelerometer integrated with an Arduino-based IoT monitoring system. Experiments were conducted using belt thicknesses of 5.7 and 6.5 mm, widths of 125 and 150 mm, and a fixed belt spacing of 40 mm. Three belt installation configurations, namely Outside–Outside, Outside–Inside, and Inside–Inside, were evaluated. Vibration signals were processed using the Fast Fourier Transform (FFT) to identify dominant frequency components and evaluated in accordance with ISO 10816-3. The results showed that the Outside–Inside configuration produced the lowest vibration level, with a velocity of  0.39 mm/s, corresponding to the “Good” classification. This performance was attributed to more balanced load distribution and smoother force transmission, which reduced dynamic excitation and improved mechanical stability. These findings highlight the importance of belt configuration in improving pump stability and provide useful insights for future condition monitoring and predictive maintenance studies.
