Abstract
Maintaining the quality of the product in the range of output specifications are the target of the production process to meet customer needs. A customer in this case consists of two major groups ie the internal customers and external customers. Its products are in the range of the upper and lower specification limits can be known through calculation of process capability analysis of process capability ratio (Cp), the upper limit process capability index (CPU), under limit process capability index (Cpl) and process capability index (Cpk) . The four indicators showed the ability to process the production process can be accepted or not. This research was conducted at a ceramics factory, especially the Press-Kiln station where one of CTQ’s (Critical to Quality) is the size of the ceramic kiln exit where the measurement data obtained by Cp and Cpk is less than one or a production process can not be accepted by Quality level of only 55.84%. Analysis of repairs carried out by using Six Sigma methods, ie, DMAIC (define, measure, analyze, improvement and control). The results obtained showed the existence of quality control materials that are not adapted to the specification of input material (powder shrinkage) of the mold cavity size as a ceramic mold in a press machine unit. Improvements setting mold cavity size is adjusted with the powder as material shrinkage, whereby the input of other parameters in setting fixed, the obtained value of Cp and Cpk improved as well as quality level rise to 75.8%. Key Word : Six Sigma, DMAIC, Process capability. Menjaga kualitas produk berada pada range spesifikasi output merupakan target proses produksi dalam memenuhi kebutuhan pelanggan. Pelanggan dalam hal ini terdiri dari dua kelompok besar yakni pelanggan internal dan pelanggan eksternal. Hasil produksi berada pada range batas atas dan batas bawah spesifikasi dapat diketahui melalui perhitungan analisa kemampuan proses yang terdiri dari ratio kemampuan proses (Cp), Indeks kemampuan proses atas (Cpu), indeks kemampuan proses bawah (Cpl) serta indeks kemampuan proses (Cpk). Keempat indikator kemampuan proses akan menujukkan proses produksi dapat diterima atau tidak. Penelitian ini dilakukan pada sebuah pabrik keramik, khususnya station Press- Kiln dimana salah satu CTQ-nya (Critical to Quality) adalah ukuran keramik exit kiln dimana berdasarkan data pengukuran diperoleh nilai Cp dan Cpk lebih kecil dari satu atau proses produksi tidak dapat diterima dengan Quality level hanya 55,84%. Analisa perbaikan dilakukan dengan menggunakan metode Six Sigma, yakni DMAIC (define, measure, analyze, improvement and control). Hasil yang diperoleh menujukkan adanya control kualitas material yang tidak disesuaikan dengan spesifikasi material input (shrinkage powder) terhadap ukuran cavity mould sebagai tempat cetakan keramik pada unit press machine. Perbaikan settingan ukuran cavity mould tersebut yang disesuaikan dengan shrinkage powder sebagai material input dimana parameter lainnya di etting tetap, maka diperoleh nilai Cp dan Cpk membaik serta quality level naik menjadi 75.8%. Kata kunci : Six Sigma, DMAIC, Kemampuan proses.
