STUDI UPAYA PENGURANGAN REJECT DIMENSI OUT PADA PRODUK CONTACT FIXED DI PT. WWW BATAM
This applied study is in line with the way to map the root cause of dimension-out reject on contact-fixed product used for electrical equipment application. Production data within 4 months was analyzed to determine the distribution of rejects with use of Pareto diagram. Investigation on major contributor of rejects namely dimension out, contributing more than 80% of total rejects, was conducted by considering different perspectives: man, machine, method, material, measurement and environment, before reconstructing fishbone diagram. The most significant factor found to produce rejects in the process was indiscipline operators who should be responsible to ensure that qualification process was conducted according to the appropriate standard. Implementation of strict Standard Operating Procedure (SOP) and certified operator system will result in a clear system, specifically, on who will take responsibility on any failure occurred during the operation. Furthermore, to expedite inspection process a standard jig is used in the production process.
