Pengendalian Persedian Material Consumable Pada Divisi Moulding Di PT XYZ

Abstract

Penelitian ini bertujuan untuk menganalisis dan merancang sistem pengendalian persediaan material consumable pada divisi moulding di PT XYZ. Permasalahan utama yang dihadapi adalah tingginya frekuensi stockout dan overstock akibat sistem pengendalian yang masih manual dan belum berbasis perhitungan kuantitatif. Metode yang digunakan meliputi analisis Pareto untuk menentukan fokus penelitian, serta klasifikasi ABC dan FSN untuk mengidentifikasi prioritas dan pergerakan material. Selanjutnya dilakukan perhitungan safety stock dan penerapan metode Min-Max untuk menentukan batas persediaan optimal. Hasil penelitian menunjukkan bahwa divisi moulding memiliki kontribusi terbesar terhadap ketidakseimbangan persediaan, terutama pada material dengan tingkat pergerakan tinggi. Penerapan metode menghasilkan parameter pengendalian berupa safety stock, titik pemesanan kembali, serta batas maksimum persediaan sebagai acuan pengelolaan stok. Penelitian ini mengusulkan sistem pengendalian berbasis perhitungan kuantitatif yang dilengkapi dengan IK stock opname serta sistem monitoring berbasis Excel VBA. Sistem ini diharapkan mampu meminimalkan risiko stockout dan overstock serta mendukung kelancaran proses produksi.

This study aims to analyze and design a control system for consumable material inventory in the molding division at PT XYZ. The main problem faced is the high frequency of stockouts and overstocks due to a control system that is still manual and not based on quantitative calculations. The methods used include Pareto analysis to determine the focus of the study, as well as ABC and FSN classification to identify material priorities and movement. Subsequently, safety stock calculations were performed and the Min-Max method was applied to determine optimal inventory levels. The research results indicate that the molding division contributes most significantly to inventory imbalances, particularly for materials with high turnover rates. The application of these methods yields control parameters such as safety stock, reorder points, and maximum inventory limits as guidelines for stock management. This study proposes a quantitative-based inventory control system equipped with stock-taking WI and an Excel VBA-based monitoring system. This system is expected to minimize the risks of stockouts and overstock and support the smooth operation of the production process.
