Abstract

CV. XYZ adalah perusahaan manufaktur yang bergerak di bidang produksi peralatan konstruksi, produk utamanya adalah peralatan air conditioning seperti blower fan dan ducting system. Penelitian ini membahas pengukuran tingkat produktivitas di CV. XYZ dengan mengukur rasio produktivitas pada indikator jam kerja, tenaga kerja, dan penggunaan energi listrik. Melalui pengukuran produktivitas yang dilakukan, hendak dirumuskan usulan perbaikan yang dapat dilakukan dalam rangka upaya peningkatan produktivitas di masa yang akan datang. Informasi yang diambil pada riset ini yakni output penciptaan, kebutuhan jam kerja, jumlah tenaga kerja, serta tenaga listrik selama tujuh bulan pengamatan. Metode yang digunakan adalah metode Objective Matrix (OMAX). Berdasarkan hasil analisa produktivitas yang dilakukan di departemen cutting dengan memakai metode OMAX dapat disimpulkan bahwa produktivitas yang terbaik terletak pada periode bulan Oktober 2020 dengan skor produktivitas senilai 1000. Sebaliknya, produktivitas terburuk terjadi pada periode Juni 2020 dengan skor sebesar 69,56. Ditinjau dari nilai indeks perubahan produktivitas setiap periode, diketahui bahwa indeks perubahan tertinggi terjadi pada periode Juli 2020 sebesar 4,69% dan terburuk pada periode September 2020 sebesar -0,49%

Abstract

PT XYZ is a company that produces hot rolled coils (HRC) steel products. One of the machines used in the process is a rough mill machine in the milling process. The problem is downtime on the rough mill machine that disrupts the production process time. The purpose of this study is to determine the value of the effectiveness of the machine, find the largest losses that affect the value of the effectiveness of the machine, identify the cause of the biggest losses and provide recommendations for improvement steps. The methods used are overall equipment effectiveness (OEE), six big losses, and the failure mode effect and criticality analysis (FMECA). The results show that the average OEE value of PT XYZ is 80%, but this value was still not following the ideal standard. By identifying the six big losses, the most significant losses are reduced speed losses, with a total percentage value of 86% and an average time loss of 5,020 minutes. FMECA results obtain three components that cause the biggest losses: the engine motor, gearbox, and spindle. Recommendations for improvement include making and setting schedules, implementing predictive maintenance and preventive maintenance on rough mill machines, and regularly checking and replacing component spare parts.
