Abstract

Pengendalian persediaan bahan baku merupakan faktor penting dalam menunjang kelancaran proses produksi dan efisiensi biaya operasional perusahaan manufaktur. PT. XYZ sebagai perusahaan manufaktur lift menggunakan material steel electro galvanized (SECC) sebagai bahan baku utama, namun pengadaan material masih berpotensi menimbulkan kelebihan dan kekurangan persediaan. Penelitian ini bertujuan untuk menganalisis penerapan metode Economic Order Quantity (EOQ) dalam pengadaan material SECC serta menentukan jumlah pemesanan optimal, safety stock, reorder point, dan total biaya persediaan yang paling ekonomis. Metode penelitian yang digunakan adalah kuantitatif deskriptif dengan data pembelian dan pemakaian bahan baku periode Januari–Desember 2025. Hasil penelitian menunjukkan bahwa jumlah pemesanan optimal sebesar 378 lembar per pesanan dengan frekuensi pemesanan 6 kali per tahun. Nilai safety stock yang dibutuhkan sebesar 6 lembar dan reorder point sebesar 49 lembar. Total biaya persediaan yang diperoleh dengan metode EOQ sebesar Rp869.357 per tahun, yang merupakan biaya paling minimum dibandingkan alternatif frekuensi pemesanan lainnya. Hasil penelitian ini membuktikan bahwa penerapan metode EOQ mampu meningkatkan efisiensi pengendalian persediaan dan meminimalkan total biaya persediaan bahan baku di PT. XYZ.

Abstract

Product quality is an important factor in the rice milling industry because it affects consumer satisfaction and product selling value. Nabila Putri Rice Mill still faces quality problems in the form of crushed rice (groats) and unpeeled rice. This study aims to identify the factors causing product defects and analyze the implementation of quality control using the Statistical Quality Control (SQC) method. The method used is Statistical Quality Control (SQC) with the help of Seven Tools, namely check sheets, histograms, Pareto diagrams, control charts (P-Charts), and fishbone diagrams. Research data were obtained through observation and documentation of the production process during the period October–November 2025. The results showed that the total rice production was 98,114 kg with the number of defects amounting to 1,011 kg or 1.03% of total production. The Pareto diagram shows that the dominant defect is crushed rice (groats) amounting to 92.28% of the total defects. The P-Chart results show that the production process is within the statistical control limits. Fishbone analysis shows that the causes of defects come from machine, method, material, and human factors. After the proposed improvements were implemented, the number of defects decreased from 1,011 kg to 837 kg, a 17% decrease. Based on the research results, the SQC method proved effective in identifying the causes of defects and assisting quality control, thereby reducing the number of defective products in the rice production process at the Nabila Putri Rice Mill.

Abstract

PT. XYZ is a manufacturing company specializing in the production of disc brakes and mufflers. This study identifies issues within the management of the M2FW Raw Material warehouse at PT. XYZ, stemming from the suboptimal implementation of the First-In, First-Out (FIFO) system. The failure to maintain an effective FIFO system has led to several serious problems, including material damage due to corrosion, discrepancies between recorded data and actual physical stock, and poor warehouse maintenance regarding cleanliness and organization. These findings underscore the urgent need for systemic and procedural improvements to ensure operational efficiency and prevent further losses.This research utilizes a quantitative descriptive approach using the Failure Mode and Effect Analysis (FMEA) method to evaluate failure risks, alongside a 5W+1H analysis to identify root causes. Data collection results during the research indicate the presence of 465 pieces of Not Good (NG) products (0.17% of total stock) with total losses reaching IDR 8,688,270.97, as well as a physical stock discrepancy of 302 pieces. Based on the FMEA analysis, work methods that deviate from standard operating procedures were identified as the most critical failure factor, yielding the highest Risk Priority Number (RPN) of 270. Applying a Kaizen approach, the proposed improvements include: standardizing methods through daily checksheets for 5S and FIFO control; implementing a structured warehouse area monitoring schedule; and categorizing supplier delivery schedules based on part size (small, medium, large) to streamline the storage process. The implementation of these steps is expected to minimize financial losses, improve stock data accuracy, and ensure operational fluidity in accordance with Standard Operating Procedures (SOP).
