PENERAPAN SISTEM PENGENDALIAN STOK PACKAGING DALAM RANGKA MENGURANGI DOWNTIME MESIN DI PT DEF

Abstract

PT DEF merupakan perusahaan manufaktur komponen otomotif dan elektronik dengan sistem produksi berbasis injection molding. Pada periode November 2025 terjadi downtime mesin sebesar 3055 jam, dengan penyebab utama keterlambatan supply packaging sebesar 18.2% yang menyumbang durasi 734 jam sehingga menyebabkan terjadinya downtime. Permasalahan ini sebabkan karena belum adanya sistem pengendalian stok packaging yang terstruktur, baik dari sisi pencatatan, monitoring stok, maupun prosedur baku perputaran packaging. Penelitian ini menggunakan metode DMADV (Define, Measure, Analyze, Design, Verify). Analisis dilakukan menggunakan diagram Pareto, diagram Fishbone, dan Pairwise Comparison. Hasil penelitian menunjukkan bahwa penerapan sistem sistem pengendalian stok packaging yang dirancang dengan metode DMADV terbukti efektif dalam meningkatkan visibilitas stok, mengurangi frekuensi serta durasi keterlambatan supply packaging, dan mampu menurunkan kontribusinya terhadap downtime mesin.

PT DEF is a manufacturing company during producing automotive and electronic components with an injection molding-based production system. In November 2025, machine downtime reached 3.055 hours, with the main cause being in packaging supply delay at 18.22%, contributing 734 hours of downtime. This problem occurred due to the absence of a structured packaging inventory control system, particularly in terms of recording, stock monitoring, and standardized packaging circulation procedures. This study applied the DMADV (Define, Measure, Analyze, Design, Verify) method. Data analysis was performed using Pareto diagrams, Fishbone diagrams, and Pairwise Comparison. The results show that the implementation of the packaging stock control system designed using the DMADV method proved effective in improving stock visibility, reducing the frequency and duration of packaging supply delays, and decreasing its contribution to machine downtime.
