Abstract

In the operational conduct of a company, especially those relating to the storage of materials and goods in warehouses, the occupational health and safety OHS) aspects are critical factors that cannot be neglected. Fire was one of the consequences of a non-standard OHS application. The purpose of this research was to provide a proposal for the design of fire protection systems in the Archives and Documents Company, which are light fire extinguishers, sprinkler systems, hydrants, and reservoirs. This research method is observational-descriptive. In conceptual planning, layout, and coordination with the company, the researchers directly perform observations on the PT Archives and Documents to analyze and identify the deficiencies of fire protection equipment owned by the associated companies. ADC requires a total of 9 light fire extinguishers, 192 sprinkler points, 6 hydrants, and a reservoir size of 343,000 liters as a fire protection system according to the National Fire Protection Association standards (NFPA). All buildings that are occupied by humans and have a risk of fire must be equipped with fire protection. for future research in the field of fire safety research to design an emergency response plan for a building by simulating it with advanced technology. By implementing the proposed fire protection, the Company can prevent fire and spread of fire more widely

Abstract

XYZ is a household plastic components manufacturer facing elevated defect rates (4–5% daily), accumulation of work-in-process (WIP) in the cooling area, and recurring labeling errors during packaging. This study evaluates the combined application of Kanban as a pull-based material flow control and Poka-Yoke as simple error-proofing devices to improve production efficiency and product quality. A quantitative descriptive approach was employed, using direct observation, time-and-motion measurements, interviews with operators and supervisors, and before–after comparisons of key performance indicators. Kanban sizing was calculated using D = 125 units/hour, L = 4 hours, S = 0.1, and container capacity C = 50 units, yielding an optimal 11 Kanban cards. Poka-Yoke implementations included automatic temperature alarms on molding machines, fixture sensors at finishing stations, and barcode-based label verification at packaging. After implementation, WIP decreased from 280 to 150 units (−46%); inter-process waiting time reduced from 45 to 20 minutes (−56%); daily output increased from 800 to 950 units (+18.7%); defect rate declined from approximately 5% to 1.8%; and labeling errors were eliminated. The results indicate that integrating Kanban and Poka-Yoke can effectively streamline production flow, reduce waste, and enhance productivity in small-to-medium plastic manufacturing operations. Implications, limitations, and recommendations for broader application are discussed.
