This study aims to analyze the shoe production process from an operational management perspective at PT. XYZ. The focus of the research is directed at the stages of the production process and the management of raw materials in supporting the smooth running and efficiency of production activities. This research uses a descriptive qualitative approach carried out through an Internship Experience Practice (PPL) at PT. XYZ. Data was collected through direct observation of production activities, interviews with relevant parties in the production department, and supporting documentation. The data obtained was analyzed by describing the production process flow, raw material management system, and production process control, then linked to the concept of operational management. The results showed that the shoe production process at PT. XYZ consisted of several interrelated stages, starting from raw material management to the main production process. The company has implemented a fairly structured operational management system, characterized by the recording of raw materials, the separation of materials by type, and the application of the First in First Out (FIFO) method to maintain material quality and smooth production. However, several operational obstacles were still found, such as limited production time, suboptimal coordination between departments, and the potential for defective products in the production process. The implementation of operational management at PT. XYZ has supported the shoe production process quite effectively, particularly in raw material management and production control. Nevertheless, improved coordination and continuous evaluation of the production process are needed to enhance operational efficiency and product quality.

This study aims to analyze the quality control of white crystal sugar production at ABC Sugar Factory using the Statistical Quality Control (SQC) method. The research employed a descriptive quantitative approach with a case study design. The primary data consisted of production volume and defective product data during the 2024 production period, while supporting data were obtained through observation and interviews with the Quality Control department. The analytical tools applied included check sheets, histograms, Pareto diagrams, p control charts, and fishbone diagrams. The results show that from a total production of 190,745.89 tons, defective products amounted to 66.70 tons, representing 0.33 percent of total output. The identified defects consisted of wet sugar at 45 percent, brownish sugar color at 30 percent, and oversized sugar crystals at 25 percent. Defective products occurred only during the first to third production periods, while no defects were observed from the fourth to seventh periods. The p chart analysis indicates that the production process was statistically out of control in the early periods but became stable and controlled in the subsequent periods. From a managerial perspective, these findings provide practical guidance for improving manufacturing quality through enhanced process control, equipment maintenance, and workforce capability development.

Product quality is described as the characteristics of a product that supports its ability to meet customer needs standards or manufacturer feasibility standards. This research was conducted on potato chip products at Osha Snack by analyzing the types of defects in potato chips and their causative factors. In this study, the method used is the seven tools method, namely fishbone diagram, pareto diagram, and flowchart diagram. In one month, 57 units of defective potato chips were obtained. The purpose of this study using the seven tools method is to find out the types of defects in potato chips and the factors that cause defects in the product to minimize the level of defects in the production period in the next period. Based on the data obtained, there are two types of defects in potato chips, including 35 units of product returns and 22 units of burnt chips and inappropriate potato cutting. On the application of quality chips.    

PT. Kali Jaya Putra is a manufacturing company that focuses on the production of wood floors. One of the products produced is solid flooring. In a series of production processes, product defects are still found up to 7.5% of total production, defects that often occur such as cracks, pinholes, roughness, and also twists which certainly affect product quality. The research conducted aims to determine the percentage of defective products, the causes of defects and the resulting impacts or effects, and to provide recommendations for improvements to minimize the percentage of defects in solid flooring products at PT Kali Jaya Putra. The method used is Six Sigma and Failure Mode and Effect Analysis (FMEA). The results of this study are that the most dominating defects are crack (53.75%), followed by pinhole defects (36.77%), twist (8.62%), and roughness (0.85%). The causes of defects in products are caused by several factors such as humans, machines, methods, materials, and the environment. Based on FMEA, it is known that the cause of the defect with the highest RPN is 384, namely operator negligence in material sorting. As for recommendations for improvement that can be given, namely conducting training on the grading of raw materials in the hope of minimizing operator errors in sorting raw materials.
