Abstract

The increasing competition in the global market and high consumer expectations for quality products, encourage companies to be able to produce quality products which meets international standards. One of the activities in improving quality that conform to product specifications is applying appropriate quality control system involving all aspects of the company that are integrated with the standard ISO 9001: 2008 as a guide. However, the rubber industry in West Sumatra still faces obstacles in the implementation of quality control techniques and tools of as experienced by ABC and XYZ. This study aimed to evaluate the application of quality control tools and techniques in the manufacturing company which is certified ISO 9001: 2008, ABC and XYZ. This research was conducted by calculating the value of DPMO (Defect Per Million Opportunities). Based on the results found that the two companies have different DPMO value. PT ABC obtained by 5,2σ sigma level from DPMO value of 94.33 for the types of defects whitespot and sigma level of 4,2σ of DPMO value of 3365.096 to defect type of metal, while the XYZ obtain sigma level of 5,3σ from DPMO value of 728.697 for the types of defects whitespot and sigma level of 4,8σ of DPMO value of 425.441 for the type of metal defects. From the analysis it can be concluded that the two companies have not been effective in applying the techniques and tools of quality control in accordance with the standards ISO 9001: 2008 in order to achieve continuous quality improvement. This is indicated by the key success factor of the implementation techniques and tools of quality control is not applied appropriately in achieving continuous quality improvement.

Keywords: Critical Success Factors, DPMO, ISO 9001:2008 Certificate, Quality Control Tools and Techniques

 

Abstrak

Peningkatan persaingan pada pasar global dan harapan konsumen yang tinggi terhadap kualitas produk, mendorong perusahaan untuk menghasilkan produk berkualitas yang memenuhi standar internasional. Salah satu kegiatan dalam meningkatkan kualitas sesuai dengan spesifikasi produk yaitu menerapkan sistem pengendalian mutu yang tepat dengan melibatkan semua aspek perusahaan yang terintegrasi pada standar ISO 9001 sebagai panduan. Namun, industri karet di Sumatera Barat masih menghadapi kendala dalam pelaksanaan alat dan teknik pengendalian mutu seperti di PT ABC dan PT XYZ. Penelitian ini bertujuan untuk mengevaluasi penerapan alat dan teknik pengendalian mutu di perusahaan manufaktur karet yang bersertifikat ISO 9001:2008, PT ABC dan PT XYZ. Penelitian ini dilakukan dengan menghitung nilai DPMO (Defect Per Million Opportunity). Berdasarkan hasil penelitian ditemukan bahwa kedua perusahaan memiliki nilai DPMO yang berbeda. PT ABC memperoleh level sigma sebesar 5,2σ dari nilai DPMO sebesar 94,33 untuk jenis cacat whitespot dan level sigma sebesar 4,2σ dari nilai DPMO sebesar 3365,096 untuk jenis cacat metal, sedangkan untuk PT XYZ memperoleh level sigma sebesar 5,3σ dari nilai DPMO sebesar 728,697 untuk jenis cacat whitespot dan level sigma sebesar 4,8σ dari nilai DPMO sebesar 425,441 untuk jenis cacat metal. Berdasarkan penelitian disimpulkan bahwa kedua perusahaan belum efektif dalam menerapkan teknik dan alat pengendalian mutu sesuai dengan standar ISO 9001: 2008 untuk mencapai peningkatan mutu yang berkelanjutan. Hal ini ditunjukkan dengan faktor kunci keberhasilan penerapan alat dan teknik pengendalian mutu tidak diterapkan secara tepat dalam mencapai peningkatan mutu yang berkelanjutan.

Kata kunci: alat dan teknik pengendalian kualitas, DPMO, faktor sukses kritis, ISO 9001:2008
