Abstract

This study aims to examine the applications of electromagnetic waves across fields such as daily life, military, and medicine. The research highlights the importance of electromagnetic waves in modern technology. A literature review method was employed to gather data from scientific journals focusing on the history, definitions, classifications, and applications of electromagnetic waves. The theoretical framework includes the development of electromagnetic wave theory, spectrum classification, and related technologies. Results reveal the use of microwaves in ovens and satellite communication, infrared in thermal imaging and guided missiles, and X-rays and gamma rays in medical diagnostics and treatment. This study underscores the significant contribution of electromagnetic waves in enhancing technological efficiency across various sectors. The findings are expected to encourage the development of innovative applications in the future.

Abstract

The Gas and Steam Power Plant (PLTGU) utilizes exhaust heat from gas turbines to produce steam, which is then used to drive steam turbines. One of the critical processes in this system is seawater desalination, which requires reliable measuring instruments to ensure the continuity and quality of the water supply. The Differential Pressure Flow Transmitter type Azbil JTD920S is used to measure fluid flow rates at four main points: Sea Water Flow (feed), Distillate Water Flow, Condensate Water Flow, and Sea Water to Ejector Condenser Flow. A decline in transmitter performance may occur due to environmental factors, corrosion, and high workload, making periodic preventive maintenance (PM) essential. This study aims to analyze the transmitter’s performance by comparing PM data with the manufacturer’s maximum specifications using literature studies, direct observation, and interviews. The calculation results show that the highest performance levels are found in the Distillate Water Flow (73.53%) and Sea Water to Ejector Condenser Flow (73.87%) lines, while the lowest is in the Condensate Water Flow (49.00%). These findings emphasize the importance of close monitoring of high-performance transmitters to prevent premature failure and maintain the efficiency of the desalination process.
