Abstract

ABSTRAK CV Akbar Metatama perusahaan Pengecoran Logam. Bulan Januari 2022 – Desember 2022 memproduksi Jimbe sebanyak 820 unit dengani tiga jenis kecacatan yaitu berlubang persentase cacat 37%, retakkan 34 unit persentase cacat 32%, ekor tikus 34 unit persentase cacat 30%. Kecacatan tersebut membuat adanya rework sehingga mengalami keterlambatan pengiriman produk, sehingga perlu memperbaiki kualitas mutu, standar pengecoran logam dan meningkatkan keuntungan. Statistic Quality Control adalah statistik pengendalian kualitas yang merupakan teknik penyelesaian masalah menggunakan metode statistik dan metode Failure Mode and Effect Analysis adalah metode untuk mengidentifikasi dan menganalisa potensi kegagalan akibatnya dan bertujuan untuk merencanakan proses produksi secara baik dan dapat menghindari kegagalan proses produksi dan kerugian yang tidak diinginkan. Hasil peengolahan data menggunakan peta kendali P untuk batas bawah (LCL), batas atas (UCL) tidak melewati batas (aman). Faktor penyebab kecacatan yaitu manusia (man) yaitu human error, Mesin (Machine) tidak ada alat pengecekan cairan logam. Material yaitu pemilihan bahan kurang. komposisi bahan 30% aluminium batangan, 70% rijekan. Metode yaitu perlu melakukan perhitungan kecepatan pengisian (fillingrate), pengecekkan cetakan (permeabilitas). lingkungan yaitu kebisingan dan suhu ruangan melebihi standar kerja. Analisis Failure Mode and Effect Analysis diketahui RPN tertinggi yaitu cacat berubang dengan prioritas pertama RPN 100, skala Severitynya tidak layak jual, Occurrence failure mode yaitu tidak ada pengecekan suhu logam (Termometer Bimetal) dan Komposisi bahan 30% aluminium batangan, 70% rijekan, skala detection control pada kegagalan (failure mode) yaitu pemilihan komposisi bahan campuran 50% dan bahan utama 50% aluminium batangan. Kata kunci: Cacat, Failure Mode and Effect Analysis (FMEA), Pengedalian kualitas, Statistic Quality Control (SQC) ABSTRACT CV Akbar Metatama a Metal Casting company. In January 2022 - December 2022, Jimbe produced 820 units with three types of defects, including holes with a percentage of 37% defect, cracks 34 units with a percentage of defects of 32%, rat tails 34 units with a percentage of defects of 30%. This defect causes rework resulting in delays in product delivery, so it is necessary to improve quality, metal casting standards and increase profits. Statistical Quality Control is a quality control statistic which is a problem solving technique using statistical methods and the Failure Mode and Effect Analysis method is a method for identifying and analyzing potential failure consequences and aims to plan the production process properly and be able to avoid production process failures and unwanted losses . The results of data processing using the P control chart for the lower limit (LCL), upper limit (UCL) do not cross the limit (safe). Factors causing defects are humans (man) or human error, Machines (Machine) do not have metal liquid checking tools, and Materials where material selection is lacking. Material composition 30% aluminum ingot, 70% mock. The method is necessary to calculate the filling rate, check the print (permeability). The environment that is noise and room temperature exceeds the working standard. Failure Mode and Effect Analysis shows that the highest RPN is a hollow defect with the first priority RPN 100, the Severity scale is unfit for sale, the Occurrence failure mode is no metal temperature check (Bimetal Thermometer) and the material composition is 30% aluminum ingot, 70% ridicule, the detection control scale on failure (failure mode) is the choice of composition of 50% mixture and the main ingredient is 50% aluminum ingot. Keywords: Defects, Failure Mode and Effect Analysis (FMEA), Quality control, Statistical Quality Control (SQC)
