Abstract

This paper analyzes the centrifugal pump maintenance system and its impact on the effectiveness of pump performance at Perusahaan Sumber Air Abadi. The study identifies current maintenance practices, evaluates their effectiveness in preventing failures and optimizing pump operation, and proposes improvements for better system reliability and efficiency. Data were collected from maintenance records, pump performance, and personnel interviews. The findings indicate key areas for improvement in preventive maintenance scheduling, spare parts management, and personnel training. Implementation of these recommendations is expected to improve pump performance, reduce downtime, and contribute to the company's overall operational efficiency. The main focus is on the transition to a proactive maintenance culture through technology adoption and continuous skills development.

Abstract

Vibration is an unavoidable physical phenomenon in motor vehicle operation and is a dominant factor affecting user comfort. Excessive and prolonged exposure to vibration can trigger various negative responses in humans, ranging from fatigue and physiological discomfort to long-term health risks such as musculoskeletal and neurological disorders. This paper presents a comprehensive review of the effects of vibration on the comfort of motor vehicle users. The discussion includes the identification of vibration sources (internal and external), the mechanisms of vibration transmission through the vehicle structure, and the biomechanical response of the human body to whole-body vibration (WBV). In addition, this paper reviews vibration measurement and analysis methods based on international standards, analyzes the physiological and psychological impacts of vibration, and discusses vibration mitigation strategies applied in modern vehicle design, including passive, semi-active, and active suspension systems, as well as ergonomic seat design. Case studies of mitigation technology applications are also included to provide a practical overview. Finally, this paper identifies existing challenges and future research directions in an effort to improve vehicle user comfort and well-being.
