Abstract

One of the products produced by PT. XYZ is in the form of a white plastic spoon in the production process, and problems are often found in the form of products having defects that significantly affect the quality, management system, and expenses of the company. To overcome this, an analysis was carried out using the Six Sigma method, and from the calculation results obtained a sigma value of 3.9 with a defect value of 10531 for a million production. From the results of the analysis carried out to push the company towards zero defects by seeking improvements to machine and human factors as the main factors for product defect problems, some of the recommendations for improvements given are to carry out maintenance on the machines and tools that exist in the company, to rearrange the machines damaged by changing parts so as not to hinder the ongoing production flow, supervising worker operators using Production Operations Standards (SOP), conducting a worker appraisal system according to applicable regulations so that workers are motivated to perform better. Keywords: plastic products, defects, quality, Six Sigma

Abstract

PT XY, a precast concrete manufacturer, especially for electric poles, faces product quality problems in the form of defects, which harm quality, management, and production costs. This study aims to identify the root causes of defects and provide improvement solutions using the Seven Tools and Failure Mode and Effect Analysis (FMEA) methods. FMEA is used to identify potential and risk of failure and to formulate priority improvement actions. The results of the study showed three main types of defects: porous fins (53.53%), skin sticking (39.56%), and mottled (6.92%). The causal factors include methods, materials, humans, and machines/tools. FMEA analysis produces the highest Risk Priority Number (RPN) for porous fins (192) caused by imprecise molds (machine/tool ​​factors). The recommended solution is to inspect and repair the moulds periodically. Skin sticking defects have an RPN of 210, caused by poor oil quality (material factors); replacing the oil with an oil-based type is the solution. Mottled defects with an RPN of 144 are caused by the low slump of the casting mixture; the solution is to guide the mixing of raw materials according to standards. This study provides specific recommendations to reduce defects in electric pole products at PT XY, focusing on mould improvement, replacement of oil types, and standardization of raw material mixing.
