Abstract

PT XYZ is a company specializing in the manufacturing of agricultural equipment. Currently, the company is facing issues related to waste in its production processes, which are negatively affecting product quality. PT XYZ aims to address these problems in order to enhance both productivity and profitability. To resolve these challenges, the company has adopted a structured approach, beginning with the development of a Material Information Flow Chart (MIFC), followed by an analysis using Failure Mode, Effects, and Criticality Analysis (FMECA) based on fuzzy logic. The results of the MIFC analysis show a reduction in lead time from 0.45 days under current conditions to 0.35 days under the improved scenario. This improvement is attributed to the implementation of an ERP system and the introduction of visual monitoring tools. Meanwhile, the FMECA fuzzy analysis identified the primary causes of disruptions that should be prioritized for corrective action. These include non-compliance with standard operating procedures (SOPs), high levels of mental stress among workers, the use of materials that do not meet specifications, and unfavorable environmental conditions.

Abstract

Health services require speed, accuracy, and quality in order to be able to meet expectations and increase patient satisfaction. However, in practice, problems in the form of waste are still often found in the service flow, such as long queues, long waiting times, data recording errors, and inefficient manual activities. This condition also occurs at the Nerve Polytechnic of dr. Darsono Pacitan Hospital, which is the main referral hospital in Pacitan Regency. This study aims to identify forms of waste in services at the Nerve Polytechnic and provide suggestions for improvements to improve service efficiency. The method used is a Lean Healthcare approach with the help of Root Cause Analysis (RCA) and the 5 Why technique to trace the root cause of problems. The results of the analysis using BPM show that the lead time of the initial service is 127 minutes. After the implementation of the improvement recommendations, non-value added activities were completely eliminated, so that the lead time was reduced to 68 minutes, or equivalent to a time reduction of 46.5%. The improvement recommendations are focused on improving the efficiency of polyneural services through optimizing human resources, adjusting the work system, implementing 5S, utilizing information technology, digitizing medical records, and involving medical personnel in improving service quality.
