Abstract

PT XYZ is an industrial company that produces vehicle spare parts. So far, raw material inventory planning has been carried out based on estimates of past needs, methods like this will result in uncertainty raw material needs which will cause total inventory costs to increase, stockouts, and overstocks. This research aims to evaluate the company's raw material inventory procurement, to obtain optimal raw material inventory procurement. The research methods used are normality tests, forecasting, and comparison of the EOQ & Min method where the best method is proposed to be applied in the company. The data collection techniques used were observation, interviews, and documentation. The research results show that companies should use the EOQ method for steel raw materials and Min Max for copper raw materials, which will save inventory costs by 25.16% or IDR 9,340,698. Apart from that, the safety stock value, maximum inventory, and reorder point are also known to avoid stockouts and overstocks. By implementing inventory procurement methods, companies can find out the maximum inventory that should be in the warehouse, expedite production operational activities, and save space usage which of course benefits the company.

Abstract

This research was conducted at PT XYZ with the focus of the research being one of its business units, namely piping construction services. This research is descriptive quantitative research, namely explaining the analysis of the implementation of occupational safety and health in the pipe construction business unit of PT XYZ. Data collection techniques were observation, documentation, interviews and distributing questionnaires to 30 workers with the method used was the HIRADC method. This research aims to identify potential work hazards, assess risk levels, and analyze efforts to control potential work risks. The research results show that there are 27 potential work risks with 13 work potentials in the low category, 7 work potentials in the medium category, and 7 work potentials in the high category. Efforts to control work risks from the results of the analysis are by conducting safety briefing procedures, giving warnings if you do not use PPE and providing PPE that is not yet available, conducting work site inspections, ensuring work procedures and safety procedures (SOP), determining appropriate testing procedures, and providing workpiece tools.
