Abstract

PT. Keramik Diamond Industries (KDI) merupakan perusahaan yang bergerak dibidang industri keramik dinding dan lantai. Dalam tahapan proses produksinya masih sering terjadi berbagai penyimpangan serta hambatan yang dapat mengakibatkan produk ubin keramik (tile) dianggap cacat. Produk tile yang dianggab cacat produksi berupa : gupil sesudah glaze, gupil sesudah bakar, gupil sebelum glaze, retak body dan kotor affal. Sebagai upaya untuk menurunkan produk cacat yang terjadi di PT. KDI maka perlu dilakukan pengendalian kualitas dengan menggunakan metode six sigma dengan DMAI untuk meningkatkan kualitas produksi. Dalam tahap define terdapat 5 jenis cacat produk  yang terjadi. Pada tahap measure diperoleh produk cacat tertinggi pada cacat gupil sesudah glaze sebesar 19.398 pcs/ 35,47 % dan nilai DPMO sebesar 12.741 pcs dengan sigma level sebesar 3,8 sigma. Dari hasil analisis diperoleh faktor – faktor pemicu terjadinya cacat produk tile antara lain adalah faktor manusia, mesin, metode, material dan lingkungan. Berdasarkan analisis tersebut usulan perbaikan dapat diketahui dari hasil nilai RPN tertinggi. ABSTRACT PT. Keramik Diamond Industries (KDI) is a company engaged in the wall and floor ceramic industry. In the stages of the production process, deviations and obstacles often occur which can result in ceramic tile products being considered defective. Tile products that are considered to be defective in the form of: chipped before glazing, chipped before burning, chipped before glazing, cracked body and dirty affal. As an effort to reduce defective products that occur in PT. KDI then need to do quality control using the six sigma method with DMAI to improve production quality. In the define stage there are 5 types of product defects that occur. At the measurement stage, the highest defective product was found in the gupil defects before glaze of 19,398 pcs/ 35,47 % and the DPMO value of 12,741 pcs with a sigma level of 3.8 sigma. From the results of the analysis, the factors that trigger the occurrence of product defects include human, machine, method, material and environmental factors. Based on this analysis, the improvement proposal can be seen from the results of the highest RPN value.

Abstract

ABSTRAK Era globalisasi dan persaingan pasar yang semakin ketat, menuntut perusahaan untuk menghasilkan produk yang berkualitas agar sesuai dengan permintaan konsumen. Sebagai perusahaan industry pulp dan kertas PT. DAP memiliki beberapa jenis produk yang diperkenalkan dikalangan masyarakat luas baik dalam maupun luar kota. Sebagai upaya untuk menganalisis penyebab cacat yang terjadi di PT. DAP digunakan metode Six Sigma (DMAI). Dengan pengaplikasian metode tersebut diharapkan dapat memberikan solusi terhadap penyebab cacat produk kertas di PT. DAP. Dari pengolahan data didapatkan produk cacat tertinggi adalah blackspot dengan nilai persentase 43,85%. Berdasarkan analisis FMEA usulan perbaikan dapat diketahui dari hasil nilai RPN tertinggi.ABSTRACT The era of globalization and increasingly fierce market competition requires companies to produce quality products to suit consumer demand. As a pulp and paper industry company, PT. DAP has several types of products that are introduced among the wider community both inside and outside the city. As an effort to analyze the causes of defects that occur in PT. DAP uses the Six Sigma (DMAI) method. With the application of this method, it is expected to provide a solution to the causes of defects in paper products at PT. DAP. From data processing, it was found that the highest defective product was blackspot with a percentage value of 43.85%. Based on the FMEA analysis, the proposed improvement can be seen from the results of the highest RPN value.
