“…A structured method and techniques aimed at identifying and resolving issues are used in the root cause analysis process to determine the primary reasons for a problem (Hunusalela, Perdana, & Usman, 2019). This method has proven to give great results for the manufacturing industry in finding the cause of the problem (Haviana & Hernadewita, 2019). This method is often combined with the FMEA method to find priority problems from the many problems found (Qin, Xi, & Pedrycz, 2020).…”

In the current era, business is experiencing very rapid development, one of which is the smartphone assembly industry. With the high demand for smartphones from the public, companies will compete to be able to produce quality smartphones with predetermined standards and specifications. Quality control is needed by the company to maintain the products it produces. It is known that the company's production target is 99.50%. However, this target has never been achieved due to a large number of defect smartphones. Based on calculations using SPC and DMAIC, it is known that most defects are found in production line 1 with the type of smartphone product type B, and the type of defect, namely LTE test fail. For this reason, the research that will be carried out in this study focuses on the LTE test fail defect. The cause of the main problem in this research is machine error. Before the repair, the %p value was 2.6%, and after the repair was carried out by restarting the machine every 2 hours, the %p value was 1%.

“…This causes the company's productivity to decrease. Problems from the above phenomena must be corrected immediately to get an effective and efficient production process (Haviana and Hernadewita, 2019) and with the Lean Six Sigma (LSS) approach . Based on previous research that uses the same method to reduce waste that occurs, the Value Stream Mapping (VSM) method is used Baby, Prasanth and Jebadurai1, 2018).…”

Purpose: This study aims to analyse the waste in the production line to get an efficient production lead time. Methodology/Approach: This research uses the integration method of value stream mapping and kaizen. Based on the analysis with expert judgment, it is known that the waste comes from an inefficient factory layout. Improvements by making changes to factory layouts and merging workstations. Findings: This research has found waste caused by ineffective factory layouts based on Focus Group Discussions (FGD). Improvements by incorporating workstations and changes to the factory layout can reduce production lead time. The results showed that the production lead time decreased from 3.21 days to 2.31 days or a decrease in the ratio of 31.15%. Research Limitation/Implication: This research can also improve manufacturing performance such as cost efficiency, efficient layout, and labour reduction. So for similar companies, this research can be a reference for making improvements in reducing waste that can improve manufacturing performance so that they can compete in national and international markets. Originality/Value of paper: This paper provides benefits for the musical instrument industry regarding waste reduction. According to this research, lean production can increase the productivity and quality of the production system, because it can eliminate the waste of time or the production process. The new approach of this research is used the integration methods by involving experts through FGDs to make improvements and reduce waste in the production line.

“…This increase will have an impact on the competition with similar industries in the domestic and international markets. Tighter competition between manufacturing industries encourages every company to increase productivity and quality [1][2]. Customer satisfaction is the level of customer or consumer feeling after getting a product or service from a company.…”

Customer satisfaction is one of the main factors that must be considered by every company to compete in the global market. One way to increase customer satisfaction is to reduce defective products and reduce waste. This method is a continuous improvement that must be carried out by every manufacturing industry. The Musical Instrument Industry is one of the producers of electronic musical instruments such as pianos. The production process has occurred several problems such as low product quality and waste (ineffective processes, inappropriate layouts, overproduction, and poor production quality). The biggest problem with this company is the large number of products that are not following company standards, such as not achieving quality standards and production not achieving targets. To improve the quality of its production, companies need to make the production process streamlined so that it will create a more effective and efficient production line. A balance between effectiveness and efficiency can be made by reducing waste. Lean Six Sigma is an approach that focuses on improving quality and eliminating waste and sustainable strategy to improve product quality while reducing waste. The company's strategy to be able to compete in the global market must be able to improve product quality and eliminate waste. This study aims to improve product quality and analyze the effect of improving quality on waste. The method used is Lean Six Sigma with dynamo stages, namely pre-study, measurement, analysis, and implementation. The results showed that the quality of the product had increased. Quality improvement has a significant effect on waste.
