Abstract
Kemasan produk telah memainkan peran penting sebagai wadah penyimpanan produk. Problem dalam kualitas produk kemasan adalah sering terjadi defect yang melebihi target perusahaan dalam proses produksi dan dapat menimbulkan komplain dari customer. Cara untuk mereduksi defect yang terjadi adalah dengan pengendalian kualitas pada tingkat proses. Penelitian ini menggunakan Six Sigma sebagai acuan proses perbaikan dengan menggunakan tahapan alur Define, Measure, Analyze, Improve, Control (DMAIC). Tahap define meliputi pendefinisian objek, pembuatan operation process chart (OPC), critical proses, critical to quality (CTQ) serta menentukan prioritas defect menggunakan pareto chart. Tahap measure menggunakan Kapabilitas Proses dan DPMO untuk mengetahui kinerja proses. Tahap Analyze digunakan FMEA untuk mendapatkan prioritas penyebab kegagalan produk dalam critical proses, kemudian dilakukan integrasi menggunakan TRIZ dalam tahap improve untuk mendapatkan rekomendasi perbaikan yang cocok dalam pengembangan critical proses. Lalu dilakukan penerapan mekanisme control. Hasil penelitian menunjukkan proses printing merupakan critical proses dengan nilai DPMO 18372 serta critical defect yaitu defect miss print, garis, dan warna. Level Sigma perusahaan berada pada 3,58 sigma dan nilai Kapabilitas proses adalah 1,19. Adapun Hasil FMEA, untuk miss print disebabkan komponen cylinder yaitu gear dan bearing tidak presisi, untuk defect warna disebabkan komposisi tinta dan defect garis disebabkan tinta bagus tercampur tinta. Berdasarkan analisa contradiction matrix dan 40 inventive principle, rekomendasi perbaikan untuk proses printing dengan defect miss print yaitu melakukan pembersihan komponen gear Box menggunakan vacuum cleaner, bantuan alat vibration tester dan penambahan lock nut, untuk Defect warna melakukan pelatihan takaran viskositas dan strategi pengembangan supplier, untuk defect garis dengan pemasangan kamera di station printing dan pembersihan secara periodik di saluran pompa tinta

Product packaging has played an important role in a storage container product. Problems in the quality of packaging products is often a defect that exceeds the target company in the production process and can cause complaints from customers. A way to reduce defects that occur is the quality control at the level of the process. This research uses the Six Sigma process improvement as a reference using the stages of DMAIC. The step of definition object, include define manufacturing operation process chart, identification of defects, critical process, critical to quality as well as determine priority defects using the pareto chart. Phase measure using the Capability process and DPMO to know the performance of the process. The step of analyzing use FMEA to get priority causes failure of the products in the process, then improve used by integration the method of TRIZ to get suitable recommendations. Then apply the control mechanism. The results showed the process of printing is a critical process with the value of the DPMO 18372 Sigma Level, level sigma for the plant is 1.58 sigma and the capability of the process is 1,19. The results of FMEA, for critical defects miss print caused by the component of the cylinder, imprecision of gear and bearing, for color defects caused by the composition of ink and line defects caused by great mixed dried ink. Based on the analysis of contradiction matrix and 40 inventive principles, recommendations to repair defects miss print that is cleaning component of the gearbox using a vacuum cleaner, help tool vibration tester and the addition of the lock nut, for the colors of Defect apply training to measure the viscosity and the development strategy of the supplier. Line defects adding CCTV in station printing and periodic cleaning of the ink pump
