Abstract

The CNC machines are computer-controlled machines using numeric codes, symbols and letters as command data. A CNC Milling machine at the Mechanical Engineering Laboratory of the University of Riau has damaged and disrupted engine performance. The purpose of this study is to determine the types of damage, causes, and efforts and suggestions of actions that can be done to improve engine performance for CNC milling in Riau University Laboratory. The method is used in this research of the Fault Tree Analysis (FTA) method which is used to find the caused of the damage to the basic event and Failure Mode and Effect Analysis (FMEA) that is used to search priority problem through Risk Priority Number (RPN). The result showed damaged of components such as pneumatic cylinders of protective door, ATC pneumatic brauer units, pneumatic valves and saddle. The result of critical component analysis of leakage on pneumatic valve component was the most critical risk with RPN of 448. The actions to reduce the highest of RPN were repairing, prevention and maintenance on the CNC milling machine. Proposed repair was the replacement of components that have been damaged and optimize the precautions and maintenance in accordance with the instructions in the manual book.Keyword: FTA, FMEA, RPN, CNC Milling machine

Abstract

This paper discusses the factors that affect the damage in the office archive libraries, archives and documentation of Bukittinggi. The purpose of this paper is: (1) Describe the intern factors affecting archives damage in Office Library, Archives and Documentation of Bukittinggi, (2) Describe the extern factors that influence damage records in the Office of Libraries, Archives and Documentation of Bukittinggi. From the results of this study concluded: (1) intern factor is the destructive factor derived from the archives. Factors damaging is the archive of the paper and the ink paper and ink as an object that can be easily damaged. For avoidance of anything like this, at the time of filing in paper and ink for choose a good quality that is not easily damaged archives and in doing maintenance, do so in accordance with the terms of the world of archives, (2) factor is a factor extern archives from destroyer from outside. Factors damaging records from outside is the temperature and humidity, as well as the use of dust and mishandling. This is caused by a lack of understanding of archivists in the process of maintenance records so that the archive was damaged and difficult to use anymore. In order for archive to be managed properly filing officer should provide equipment maintenance and managing archives in accordance with archival purposes. Keywords: maintenance records; factors affecting archives
