Abstract

PT Afan Logam Lestari adalah sebuah perusahaan umum Aluminium yang bertempat di Jln.Budi Utomo, Rt.05/Rw.05, Kaliwungu, Mlaras, Sumobito Jombang. Produk yang dihasilkan PT Afan Logam Lestari yaitu berupa aluminium ingot (aluminium batangan) yang nantinya produk ini bisa untuk mensupply pabrik yang memproduksi barang berbahan dasar aluminium. PT Afan Logam Lestari memiliki berat per batangnya 20,5 Kg dengan standar kualitas produk sebesar 99,70%. Metode pengendalian kualitas adalah salah satu metode analisis yang memiliki fungsi untuk menganalisis penyebab terjadinya kecacatan yang terjadi, baik dari segi kualitas produk maupun dari segi kualitas proses produksi. Tujuan dari metode tersebut adalah untuk menemukan akar dari penyebab terjadinya kecacatan produk sehingga akan meningkatkan kinerja dan kualitas produk yang dihasilkan. Analisis pengendalian kualitas dilakukan menggunakan alat bantu statistik berupa Check Sheet, Peta Kendali, Diagram Pareto dan Diagram Sebab-Akibat, FMEA (Failure Mode Effect Analysis), Indeks Kemampuan Proses. Dari hasil penelitian dapat disimpulkan bahwa Dilihat dari P-Chart diketahuai nilai control limit (CL) sebesar 0,09811 dan lower control limit (LCL) sebesar 0,0775. sedangkan upper control limit (UCL) sebesar 0.1187 Grafik diatas juga menunjukkan pada periode 1, 4, 7, 9, 12, 13, 14, 16, 17, 18, 19, 20, 21, 22, 23, 24, 29, 30 dan 32 bergaris atau betitik merah. Hal ini menunjukkan pada periode tersebut jumlah defect tidak dalam batas kendali atau diluar batas kendali. Sehingga dalam sistem pengolahan aluminium alloys keluar dari out of spesification atau bisa disebut dengan keluar dari spesifikasi. Maka perlunya perbaikan berskala untuk meminimumkan Cacat.
