Analisis Performansi Nakayama Plant Menggunakan Metode Ramd di PT XYZ

Abstract

PT XYZ is one of the manufacturing industries engaged in the manufacture of spare parts on a national scale. One of the products produced by PT XYZ is magnifold intake pipe which is made in nakayama plant. Based on data from nakayama plant obtained system breakdown structure of the system namely Sand Core, Furnace Gravity, Finishing, Machining, Leaktest. Of the five subsystems will be selected critical subsystems based on the results of RAMD analysis. The result of the data processing that has been done is known that the Reliability value of the system at the time of t = 8 hours is 63.92%. Availability markov process value is 98.546%. The average value of Maintainability at the time of t = 8 hours is 98.951%. The lowest Dependability and Dependability Ratio values are in the Gravity Furnace subsystem with values of 95.634% and 131.759. Therefore, it can be known that the critical subsystem in the system is gravity furnace so it needs to be maintained regularly and scheduled.
