PENGARUH PERFORMA DAN PERAWATAN IMPELLER POMPA AIR LAUT TERHADAP KOMPRESOR AC DI KM CIREMAI

Abstract

Sulthoni, Ahmad.2025 “The Effect of Seawater Pump Impeller Performance and Maintenance on AC Compressors KM. Ciremai” The study is motivated by the crucial role of seawater pumps in the AC compressor cooling system on the KM Ciremai ship. Frequent issues such as decreased pump pressure, impeller fouling, and pump leaks disrupt the cooling system's efficiency and the comfort of passengers and crew. The research aims to analyze the impact of inadequate maintenance and performance decline of the seawater pump on impeller fouling, as well as the relationship between lack of maintenance and pump performance degradation. The research employs a quantitative method with a descriptive approach. Data were collected through questionnaires distributed to 70 crew members of KM Ciremai as respondents. Data analysis was conducted using SmartPLS SEM (Partial Least Square – Structural Equation Modeling) software to test validity, reliability, and variable relationships. The results indicate that inadequate pump maintenance significantly affects pump performance decline and impeller fouling. Additionally, decreased pump performance directly influences impeller fouling. The study concludes that the performance and maintenance of the seawater pump impeller significantly impact the AC compressor's efficiency in KM Ciremai. Therefore, it is recommended to enhance the frequency and quality of pump maintenance and conduct regular monitoring of the impeller's condition to prevent fouling and maintain the cooling system's efficiency.
