Abstract

Company shall give full attention to the quality of the products. In the electronics industry, quality control is the key to gain the loyalty of the customer. This is the basis for making improvement at the production activities, especially in controlling the quality in order to reduce the problem of scratch on the cover bottom using the six sigma DMAIC method. The purpose of this research is to analyze the factor that will cause defect to the product. The aimed target is to reduce the lower problem of defective products cover bottom 50%, it also to get the best result where previous defective products amounted to 8183 ppm has downed to 291 ppm and the level of the previous sigma 3,89σ rose to 4,94σ, the target is 4,14σ. This was result an exceed achievement from the Company’s target more than 50%. Six Sigma is the most effective tools at the present time, this will affect to eliminate defects, cut the time of making the product, eliminate unnecessary costs and the principal concept of science to support the sustainability of business which is focused on improving quality and customer satisfaction. The key success of improving quality depends on the ability to identify and solve the problems. This application may be useful and align with the company's philosophy, so that it can be expected to get the final outcome of the company.

Abstract

XYZ.Co.Ltd as one Oil and Gas Company where on need steam which produced by Boiler to support of production system operational , Conductivity of Boiler Feed Water (BFW) which generated by Mix Bed Filter (MBF) have been controlling by Online Analyzer and Laboratory. Beginning from 01 April 2017 has happened data discrepancy between Online Data Result against Laboratory Result. Gap Analysis have done to determine of Desire Situation / Goal, and Goal of Research is mitigate of difference conductivity value which resulted by Online Analyzer against Laboratory. Then, Root Cause Analysis uses Ishikawa Diagram to observe root cause of the problem with several action plans to do. Ishikawa Diagram analysis uses to Root Cause Analysis resulted 1 (one) Non-Conformity has found in Machine Factor is Three Level Calibration of Conductivity Meter in Online Analyzer, because after did Chi-Square test to hypothesize of data which is generated of X2calc > X2crit as rejected and this Root Cause Analysis result has reported to Online Analyzer Section to do some Corrective Action then after Corrective action there is no discrepancy data’s anymore. Keywords: Conductivity; Online Analyzer; Laboratory; Ishikawa Abstrak XYZ.Co.Ltd sebagai salah satu Perusahaan Migas yang membutuhkan steam yang dihasilkan oleh Boiler untuk menunjang operasional sistem produksi, Konduktivitas Boiler Feed Water (BFW) yang dihasilkan oleh Mix Bed Filter (MBF) telah dikontrol oleh Online Analyzer dan Laboratorium. Mulai tanggal 01 April 2017 telah terjadi ketidaksesuaian data antara Hasil Data Online dengan Hasil Laboratorium. Gap Analysis dilakukan untuk menentukan Situasi/Tujuan yang Diinginkan, dan Tujuan Penelitian adalah memitigasi perbedaan nilai konduktivitas yang dihasilkan oleh Online Analyzer terhadap Laboratorium. Kemudian dilakukan Root Cause Analysis menggunakan Diagram Ishikawa untuk mengetahui akar permasalahan dan beberapa rencana tindakan yang harus dilakukan. Diagram Ishikawayang digunakan Root Cause Analysis menghasilkan 1 (satu) Non-Conformity yang ditemukan pada Faktor Mesin yaitu Kalibrasi Tiga Tingkat Conductivity Meter pada Online Analyzer, karena setelah dilakukan uji Chi-Square untuk menghipotesiskan data yang menghasilkan X2calc > X2crit ditolak dan hasil RoottCause Analysis dilaporkan untuk dilakukan tindakan perbaikan pada online analyzer dan setelah dilakukan perbaikan maka perbedaan hasil pengukuran tidak terjadi lagi.
