Abstract
PT SURYA TOTO INDONESIA, Tbk is a company engaged in fittings, sanitary wares and kitchen sets. The faucet is the main product at the fitting division. In production, the company always seeks to produce a good product. However, the field defect levels fluctuate, so that becomes a major concern for the company. This study aims to determine the level product quality control defects using statistical tools such as check sheets, X and R control charts, cause-effect diagrams and ANOVA methods. Check sheets are used to present data to the analysis, then measured with X and R control chart, then look for the factors that cause defects with ANOVA approach and cause-effect diagrams to recommendations quality improvement. Analysis the production process is within control limits but the movement of the dots significant irregular, with the capability of plating layer thickness measurement process is low, the value is only 70% of the targets to be achieved. From the analysis of cause-effect diagram ukihage defect factor from human factor by undisciplined, less skilled, less concentration and decreased motivation. The second cause of the working methods and procedures that do not fit one. The third is less quality and dirty material. The Cause of the latter is less than optimal the machine, so that the company can take corrective action to prevent and suppress the defect rate ukihage and improve product quality. Keywords : Quality Control, X and R Control Chart, Anova, cause-effect Diagram, Defect PT SURYA TOTO INDONESIA, Tbk adalah perusahaan yang bergerak dibidang fittings, sanitary wares dan kitchen set. Keran merupakan produk andalan divisi fittings. Dalam produksinya, selalu berupaya menghasilkan produk yang baik. Akan tetapi, dilapangan tingkat cacat fluktuatif, sehingga menjadi perhatian utama bagi perusahaan. Penelitian ini bertujuan untuk mengetahui pengendalian kualitas menekan tingkat produk cacat menggunakan alat bantu statistik berupa check sheet, peta kendali X dan R, diagram sebab-akibat dan metode ANOVA. Check sheet digunakan untuk menyajikan data agar memudahkan dalam analisis, kemudian dilakukan pengukuran dengan peta kendali X dan R, selanjutnya mencari faktor-faktor penyebab cacat dengan pendekatan ANOVA dan diagram sebab-akibat untuk menyusun rekomendasi usulan perbaikan kualitas. Hasil analisis menunjukkan bahwa proses produksi berada dalam batas kendali tetapi terjadi pergerakan titik-titik yang tidak beraturan yang signifikan, dengan kapabilitas proses pengukuran ketebalan lapisan Plating rendah, nilainya hanya 70% dari target yang ingin dicapai. Dari analisis diagram sebab akibat diketahui faktor penyebab cacat ukihage berasal dari faktor manusia disebabkan karena tidak disiplin, kurang terampil, kurang konsentrasi dan motivasi yang menurun. Penyebab kedua metode kerja yang tidak sesuai prosedur dan salah. Ketiga kualitas material kurang baik dan kotor. Penyebab terakhir mesin yang kurang optimal, sehingga perusahaan dapat mengambil tindakan pencegahan serta perbaikan untuk menekan tingkat cacat ukihage dan meningkatkan kualitas produk. Kata kunci : Pengendalian Kulitas, Peta Kendali X dan R, ANOVA, Diagram Sebab Akibat, Cacat
