Abstract

PT. XZ is a company engaged in the manufacture of flip-flops. One of the sandal products produced is Screen-printed flip flops. However, in every production process failure is inseparable in the form of defective products in the production process. The purpose of this research is to minimize defects in Screen printing products. To reduce these defects, it is necessary to analyze the production process using the Statistical Process Control method. The analysis was carried out by using Seven Tools and 5W+1H tools. The results of the analysis show that the types of defects that occur in Screen printing products are the color of the paint is uneven, the paint is smeared and peeled off, and the Screen printing is not precise. Based on the three types of defects, the most dominant defect is uneven paint color with a percentage of 41,8%. Screen printing product defects are caused by human, machine, material, and method. Improvement efforts made to minimize the occurrence of uneven/fading paint color defects, namely conducting briefings and conducting supervision and checking on Screen printing results, checking on the Screen before printing is done, checking paint before printing, and providing training on rework standardization to employees and conducting regular performance evalutions.

Abstract

PT GMK is a company in the chocolate industry, with its main product being Collata chocolate blocks. Despite being one of the leading producers, the company faces significant challenges in maintaining product quality, especially regarding color, aroma, and weight, which do not meet specifications and could potentially reduce consumer trust. This study aims to identify the root causes of product defects and offer corrective solutions using the Failure Mode and Effect Analysis (FMEA) method and Fishbone Diagram analysis. Based on data from observations and interviews with the production and quality control teams, three main defects were identified with the highest Risk Priority Numbers (RPN): color deviation (RPN 540), aroma deviation (RPN 245), and weight deviation (RPN 120). The Fishbone analysis reveals that human, machine, environment, and method factors significantly contribute to these defects. Proposed corrective actions include retraining operators to improve process understanding, periodic calibration of weighing machines, and improving production environment conditions by adding adequate ventilation. Implementing these improvements is expected to reduce defect rates and enhance the consistency of chocolate bar quality at PT GMK. Additionally, it will strengthen the company’s competitiveness in the market by ensuring higher consumer satisfaction and loyalty
