Abstract

The homogenizer is one of the critical machines in the NonDairy Creamer production process due to its role in producing stable and uniform emulsions. Frequent failures in the homogenizer can increase downtime and reduce production effectiveness. This study aimed to identify critical components causing downtime, determine appropriate maintenance strategies using the Reliability Centered Maintenance (RCM) approach, and evaluate the impact of Total Productive Maintenance (TPM) implementation on homogenizer reliability at PT CRM. The research methods included downtime analysis, calculation of Mean Time To Failure (MTTF) and Mean Time To Repair (MTTR), Failure Mode and Effect Analysis (FMEA), Logic Tree Analysis (LTA), and the development of maintenance strategies based on RCM integrated with TPM. The results showed that the homogenizer contributed 2,007 minutes or 69% of total production downtime. The most critical component was the plunger gasket with a Risk Priority Number (RPN) of 504. The implementation of the proposed maintenance strategy reduced downtime by 69%, decreased failure frequency by 67%, increased MTTF from 4,623.75 minutes to 13,871.25 minutes, and reduced MTTR from 83.63 minutes to 76.25 minutes. These findings indicate that the integration of RCM and TPM effectively improves homogenizer reliability and supports sustainable production performance.

Abstract

This research discusses the high level of defective packaging in the WIP Chocogranule production process at PT TES, which leads to waste and reduced production efficiency. The main problem identified is non-standard packaging cuts. The study aims to determine the dominant factors causing defects and to design continuous improvement strategies using a DMAIC-based Lean Six Sigma approach combined with Kaizen, the seven quality tools, FMEA, and the 5W+1H method. The research focuses on five waste-causing factors: machines, materials, methods, manpower, and the environment. Primary data were obtained from observations of packaging defects using a sample of 100 pieces per day, while secondary data consisted of inner cellophane variance before and after improvements. The analysis results indicate that the dominant defect is non-standard packaging cuts, accounting for 73.13% of defects, with an average of 1.95 defects per 100 samples. The initial DPMO value was 8,889 with a sigma level of 3.87. The improvement phase produced six main corrective actions, including machine modifications, process standardization, changes in packing flow, increasing eyemark width, and operator training. The implementation of these improvements successfully reduced cellophane waste from 2.67% to below the company’s KPI target of 0.67%, with the DPMO value decreasing to 2,222 and the sigma level increasing to 4.34. This study demonstrates the effectiveness of Lean Six Sigma and Kaizen in improving quality and efficiency in the production process.

Abstract

Product quality is one of the important factors in maintaining customer satisfaction and increasing the competitiveness of cosmetic manufacturing companies. PT PTI, as a cosmetic manufacturing company, still faces problems related to the high number of Rejects in the powder packaging process, especially bottom sticker tearing defects, inject hitting printing defects, and cut bottom sticker defects. The high Reject rate causes decreased production effectiveness, increased material waste, higher production costs, and reduced packaging quality. This study aims to identify the factors causing Rejects in the powder packaging process and to determine improvement proposals to reduce the Reject rate in Powder Division Zone A at PT PTI. The methods used in this study are the Plan, Do, Check, Action (PDCA) approach and Failure Mode and Effect Analysis (FMEA). Data processing was carried out using histograms, Pareto diagrams, fishbone diagrams, and Risk Priority Number (RPN) analysis to determine improvement priorities based on the highest level of failure risk. The research data were obtained from production and Reject data during the W36 to W41 period in 2025 at Line PNP 03 of Powder Division Zone A. The results showed that the dominant Reject type was bottom sticker tearing, with a total Reject of 5,200 pcs or 45.87% of the total Rejects. Based on the FMEA analysis, the highest RPN value obtained was 567 for the bottom sticker tearing defect, making it the main priority for corrective actions. The main causes of the Rejects originated from machine factors, work methods, materials, and operators. The proposed improvements include periodic machine setting inspections, improving operator accuracy, routine machine maintenance, establishing machine setting standards, and increasing supervision in the packaging process. The implementation of the improvements showed a decrease in the number of Rejects in the powder packaging process. By implementing the PDCA and FMEA methods, the company is expected to improve product quality, reduce the number of Rejects, and increase the effectiveness and efficiency of the production process in Powder Division Zone A at PT PTI in a sustainable and optimal manner.
