Abstract
Introduction: The readiness of military defense radar is absolute in air surveillance to keep from potential threats that may endanger the security of nation. Good maintenance is closely related to the readiness level of the defense radar system.
Purpose: This study aims to localize the components of the radar cooling system which need to have more spare parts inventory because they have a higher probability of failure compared to other components.
Methods: Maintenance through the application of Reliability Centered Maintenance (RCM) and Failure Mode Effect and Criticality Analysis (FMECA) could be one solution in maintaining the readiness of the air defense system.
Main finding: Mean time to failure (MTTF) calculations can provide predictions of the maintenance time that must be done and preparation for the availability of the required spare parts.
Implication: The research begins with collecting data on function, performance, component item health status, and failure records that have occurred. Critical analysis using FMECA to support information for CRM about each items function failure mode, probability occurrence, failure causes, and effect. This is necessary to determine the maintenance task and prevent the possibility of system breakdown or fatal damage.
