Abstract

Kualitas adalah kesesuaian antara tujuan dan manfaat. PT. Sinar Karya Duta Abadi merupakan perusahaan yang bergerak di industri keramik untuk melayani segmen pasar menengah ke bawah. Sebagai upaya dalam menjaga kualitas, dilakukan inspeksi terhadap hasil produksi agar kualitas keramik jadi (finished good) sesuai dengan spesifikasi. Karakteristik kualitas yang digunakan yaitu kekuatan lengkung (bending strength) dan kekuatan putus (breaking strength) karena memiliki pengaruh terhadap kualitas keramik yang dihasilkan. Perusahaan memiliki target produk keramik yang cacat sebesar 3%. Namun, dalam 3 bulan terakhir di tahun 2018 persentase produk cacat melebih target perusahaan dan terus mengalami kenaikan yaitu pada bulan Oktober sebesar 3,61%, November sebesar 3,73% dan Desember sebesar 3,88%. Oleh karena itu perlu dilakukan analisis kapabilitas proses untuk mengetahui kinerja dari proses produksi keramik apakah sudah kapabel atau belum. Hasil dari analisis tersebut pada bulan Januari 2019 (Fase I) dan Februari 2019 (fase II) dengan peta kendali Generalized Variance dan T2Hotelling proses telah terkendali dan memiliki indeks kapabilitas proses MCpl sebesar 0,885 pada bulan Januari 2019 dan 0,705 pada bulan Februari 2019. Terjadi penurunan kapabilitas proses dari bulan Januari 2019 ke bulan Februari 2019. Hal tersebut terjadi disebabkan meningkatnya intensitas listrik padam pada bulan februari 2019.

Quality is the match between goals and benefits. PT. Sinar Karya Duta Abadi is a company engaged in the ceramic industry to serve the middle and lower market segments. As an effort in quality, Inspection of production results is carried out so that the ceramic quality is in accordance with specification. The quality characteristics used are bending strength (flexural strength) and breaking strength (breaking strength) because it has an influence on the quality of the ceramic produced. The company has a target of 3% defective ceramic products. However, in the last 3 months in 2018 the percentage of defective products exceeded the company's target and continued to increase in October by 3.61%, November at 3.73% and December at 3.88%. Therefore it is necessary to analyze the capability of the process to find out whether the ceramic production process needs be capable or not. The results of the analysis in January 2019 (Phase I) and February 2019 (phase II) with the Generalized Variance and T2Hotel control chart processes have been controlled and have MCpl process capability index of 0.885 in January 2019 and 0.705 in February 2019. Changes occur in process capability from January 2019 to February 2019. These things happened related to the difficulty of power outages in February 2019.
