Knowledge Conversion Perancangan Instruksi Kerja Kegiatan Preventive Maintenance HAAS CNC Milling dengan Metode SECI

Abstract

Nowadays to gain a competitive advantage in an organization, knowledge
becomes important as an asset that must be managed. The experience
possessed by humans is tacit and sometimes difficult to extract into a
procedure or standard that can be used in an organization. T University is a
private university in Indonesia. At the University of T, there is a laboratory
that serves as a provider of practical services for students, one of the laboratory
is laboratory X. Laboratory X serves to provide an understanding in the
Manufacturer process for mass production. Currently, this laboratory consists
of 18 assistant labs and one laboratory staff. This laboratory has one Haas
CNC Milling used in labwork activity. To keep the machine in optimum
condition, good maintenance management of the facility is required especially
preventive maintenance, these activities are conducted based on the experience
of laboratory staff in handling Haas CNC Milling machine. The problems
occur when the laboratory staff is entering the retirement period. Besides that
until now there is no standard operation procedure (SOP) developed by the
university about how to do preventive maintenance. This research aims to
design preventive maintenance work instruction for CNC Milling Haas
machine with SECI (Socialization, Externalization, Combination, and
Internalization) methods. Best practice in the form of a work instruction is
obtained from the process of knowledge conversion from laboratory staff and
head of laboratory. From the exploration result, it is known that preventive
maintenance activities for Haas CNC Milling machine consist of spindle
cleaning, checking tools, lubrication check and engine coolant, and run test.
Brainstorming is done to confirm and select best practices created by both
speakers. From the brainstorming result, it is known that the work instructions
performed by the laboratory staff are selected by modifying some aspects of
checking.
