Abstract

Demineralization water is removal of dissolved ionic mineral impurities present in water and other liquids. Mineral content in water can cause crusts in power plant equipment such as boilers and turbine, lowering yield and selectivity values in the reaction process. The aim of the research is to diagnose the conditions of water process Tanjung Enim thermal power plant with standard value of ASME CRTD Vol. 34 and Power Plant water treatment standard. Demineralization Water treatment process starts from Multimedia Filter (MMF), Carbon Filter (CF), Reverse Osmosis (RO), Electrodeionization. Demineralization water sampling taken in January, february, march and April. The water sampling used in RAW Water, Feed RO, Electrodeionization process, feed water and boiler drum to measure the parameters of pH, conductivity, turbidity, Fe, Cl2 and Si02, P04 and ions of Na+, Fe+, Cu+ some of parameters result the fluctuative value but still in both of water treatment standard.

Abstract

This study aims to analyze the effect of voltage quality variations on the performance and estimated operational lifespan of electronic equipment. The study uses a quantitative explanatory approach with a field measurement design (in-situ) through the use of a power quality analyzer and supporting instruments. Data were analyzed using descriptive statistics, correlation analysis, and multiple linear regression. The results show that voltage quality variations occur unevenly, with the highest level of disturbances in areas with high electronic load density. Total harmonic distortion (THDv), voltage sag, and voltage unbalance are the most dominant factors influencing performance degradation and accelerating equipment operational degradation. The regression model shows a significant effect with strong explanatory power. This study confirms that voltage quality variations directly impact short-term performance and contribute to equipment operational lifespan reduction through the accumulation of electrical and thermal stress, making power quality management a crucial aspect in improving system reliability and efficiency of educational building facility management
