Abstract

Human error can be prevented by measuring human reliability through the Human Reliability Assessment approach. PT A is a national scale salt producer that produces salt. The quality division identifies human error problems made by operators in the salt refining process. This study aims to identify, calculate probability values, and provide recommendations for improvement to reduce human error in salt refining production operators. HEART and SHERPA are research approaches used because they are considered the most suitable for this study. The results showed that the most visible human error for the error mode category was C2, incomplete checking, and 42 error modes because the operator infrequently did a complete check. The process with the highest Human Error Probability value is the drying process 1, with a value of 7.49. In contrast, the process with the most minor Human Error Probability value score of 0.085 is the bagging process 2. Human error prevention efforts are carried out for each process based on the highest score on the Human Error Probability Index, including Personal Protective Equipment, Standard Operating Procedures, and training to improve operator skills.

Abstract

Quality assurance is an action to maintain customer satisfaction. As a prominent fabrication producer, Firm A, which receives regular orders from corporate clients, has been challenged with maintaining quality consistency during the production process of filter tanks. This study aims to identify risks and evaluate failures that occur during the filter tank production process based on the Failure Mode and Effects Analysis method. The FMEA stage was started with a walkthrough survey to identify defects, followed by brainstorming sessions with two expert respondents to determine the severity, occurrence, and detection score. Subsequently, the Risk Potential Number score was calculated. Research findings distinguished three types of defects during production stages, namely welding, asymmetric, and painting. Based on risk quantification, it was found that the highest defect score, 392, was attributed to the painting failure category, characterized by excessively thick paint results. This finding was followed by the second-highest score of 336, and the third with value of 294 as failure of asymmetric joints. The practical implication in complementary of the FMEA finding showed that systematic training, audits, and briefings are suggested to address the issues that cause the highest number of failures on fabrication process.

Abstract

CV. AAA is a company engaged in the production of water tanks. As a player in the manufacturing industry, CV. AAA performs continuous improvement in each production process to minimize losses due to non-value-added activities due to waste and ineffectiveness in carrying out the production process. This research objective evaluates activities that cause waste in the water tank production line with a Lean approach and ergonomics. This research begins by describing the current state map to identify waste throughout the production flow. Followed by the analysis of the occurrence of non-value-added activities at the stages of the production process. The results showed that three wastes were identified, namely Waiting, Defect, and Excess Processing. The non-optimal production process is because the tools used are manual labor which can lead to the risk of muscle injury to the operator. Nordic Body Map Scoring result obtained from four operators found that the final score is from medium to high level. Scenario improvement presented in future state map shows in reducing cycle time as well as lead time.
