As known, thermal is one of the important causes of machine failure, especially in the rotational parts like shaft or bearing in coating machine for fiber-plastic bag industry. While machine is running, temperature is getting higher and accumulates. In order to protect machine failure from overheat, this research developed the real time CBM to keep...

... higher MTTF, the longer shaft lifetime. From Fig.6, it was found that most measured shaft temperature (T) was shown out of specification (> 26 o C) and it caused low reliability, high failure rate and low MTTF as summarized in Table 1. The average temperature was calculated every working day and the reliability can be calculated by using this information. ...

... Reliability becomes a very important thing in the design of a product. This is due to several reasons such as customer satisfaction, operating and maintenance costs, repeat business, and competitive advantage [4], [5]. In addition, if we look at it from a maintenance perspective, reliability is very influential on the availability of a product [6]. ...
High-speed train (HST) Indonesia is rail-based public transportation which is planned to be implemented in Jakarta-Surabaya. To maintain the HST for excellence service, it is necessary to conduct a study on the quality of the service. This paper tries to approach the Bogie system quality service from the reliability perspective in the design phase. The steps taken to maintain continuity of service quality are to identify critical sub-systems/components that affect the decline in reliability, Risk Analysis, build Reliability Block Diagram (RBD) from sub-system/components that have been identified in the bogie system, calculate initial reliability based on RBD, develop designs to minimize the potential for a decline in reliability, and compile procedure for evaluating and re-calculation the value for the reliability of the bogie system. Reliability is targeted at 0.9, which means that all service quality designs must always make the reliability value above the target. This paper is expected to provide an overview of potential that may occur based on predictions of decreasing reliability values until the operating period ends. So that anticipation of minimizing the decline in the value of reliability can be done.
