“…Salah satu usaha perusahaan untuk menjaga kualitas adalah dengan melakukan pengendalian kualitas. Menurut Sofyan Assauri (Akbar, 2020) pengendalian dan pengawasan adalah kegiatan yang dilakukan untuk menjamin agar kegiatan produksi dan operasi yang dilaksanakan sesuai dengan apa yang direncanakan dan apabila terjadi penyimpangan, maka penyimpangan tersebut dapat dikoreksi sehingga apa yang diharapkan dapat tercapai. Maka dari itu pengendalian kualitas perlu dilakukan terutama di awal proses produksi berlangsung yaitu pengecekan kualitas bahan baku.…”

Steel is one of the raw materials used by PT. XYZ in the manufacture of its defense products; therefore, quality control (QC) and checking process become the most essential part in the process. To ensure that the steel raw materials used reach the standards, metallurgical properties are examined using several criteria must be carried out well, as microstructure, grain size, decarburization and impurities (inclusions). Inclusions or impurities are unwanted non-metal compounds and are the main factor for the initial appearance of ductile fracture and brittle facture during the production process. The severity of the inclusions in steel raw materials affects the next process so that errors in readings to determine the severity of minor or major inclusions must be minimized. This is because when the inclusion severity level that read is included in the major level then the steel raw material cannot be used and turns to be scrap and causes losses to the company. To minimize the matters, operator accuracy is required in analyzing by a comparison table, because this method analyzes the inclusion compounds one by one and it takes ± 1 minute to determine the severity. The purpose of this research is to build a quality decision-making system based on fuzzy mamdani logic that is used to determine the severity of inclusions and to compare the results of system processing with operators to see the accuracy of the system and time efficiency that has been built. In this study using the Mamdani fuzzy logic method with the variables used are Alumina inclusion length, Silicate inclusion length, Alumina inclusion width and Silicate inclusion width. The system is built using matlab software. The system test results from the 6 samples used to obtain comparisons according to the operator and the system are stated to be minor, making the accuracy obtained quite good and in terms of time, the determination process with the system takes less time, namely ± 2 seconds

Pengendalian mutu produk spring coil belum dilakukan dengan baik, dimana terindikasi sebagian besar cacat berada di luar batas kendali. Penelitian ini dilakukan pada perusahaan yang bergerak di bidang manufaktur khususnya spring coil. Tujuan dari penelitian ini adalah untuk meningkatkan kapabilitas proses dengan mengurangi variasi proses yang terjadi. Metode yang digunakan adalah Six Sigma DMAIC. Didapatkan nilai Cp sebesar 0,8, yang berada pada range Cp < 1 sehingga dapat disimpulkan bahwa nilai kapabilitas proses masih di bawah dan perlu dilakukan perbaikan agar Cp mendekati angka 1. Kemudian didapatkan nilai DPMO sebesar 8173,721 dengan nilai sigma sebesar 3,901. Dari analisis yang dilakukan didapatkan bahwa penyebab utama defect adalah roda gigi sudah somplak/aus dan setelan baut sudah berubah. Maka dari itu, dilakukan usulan kartu preventive maintenance. Usulan yang diberikan selanjutnya adalah kartu pengendalian bahan baku guna mengkontrol kualitas bahan baku dari supplier. Tindakan lain yang dapat dilakukan adalah dengan melakukan perhitungan DPMO secara bulanan. Hal ini dilakukan guna mengendalikan proses produksi yang sedang berlangsung. Usulan terakhir adalah dengan kartu rencana kaizen 5S/5R, yakni untuk memperkenalkan bahwa perubahan kecil dapat membawa dampak perubahan positif secara berkelanjutan. Dengan adanya usulan-usulan tersebut maka permasalahan yang terjadi, yakni defect yang masih tinggi akan dapat berkurang. Maka dari itu perusahaan tersebut perlu melakukan control untuk mempertahankan usulan yang telah diberikan atau bahkan ditingkatkan lebih dari sebelumnya.

“…Using the six sigma method can help understand and identify the causes of problems to improve product quality. The use of the six sigma method focuses on reducing variance to minimize the opportunity for defects to occur (Subana et al, 2021). Then the Fuzzy AHP method is used which is an improve level of AHP, because the AHP method as shortcomings in the form of a lack of ability to overcome uncertainty and vague decisions in decision making (Doaly et al, 2019).…”

PT. XYZ is a manufacturing industry that produces various cleaning equipment. One of the products that has a high level of defects are trash bins made of stainless steel. The purpose of this research is to improve the quality of stainless steel waste products. The method used is Six Sigma and Fuzzy Analytical Hierarchy Process. In the Define stage, the types of defects found were body dents, scratches, spots, and rough covers. In the Measure stage, the initial DPMO value obtained is 3.422. In the Analyze stage, the results of the analysis process are defects with the highest Risk Priority Number of 280. The next stage is Improve, where defects with the highest RPN value are prioritized for proposed improvements using Fuzzy AHP. Based on the results of the Fuzzy AHP assessment, it was found that the highest weight was alternative 3, namely the machine must be cleaned regularly after being used at 0.4322, alternative 2, namely the addition of material handling to facilitate product transfer of 0.2048, and alternative 4, namely the establishment of SOPs for product handling. of 0.2041. After the Improve stage, the final stage in the form of Control is carried out to see whether the implementation of the proposed improvements has a positive impact on the company. The DPMO results obtained after implementation were 3.6061.
