Abstract

In this era, technology is developing very rapidly in various sectors ranging from industry, health, education, retail, and various other sectors. The development of technology is linear with human needs that must be met quickly, easily, and practically. A sector that can fulfill human needs is the trade sector. Currently, the trade sector is one of the sectors that is highly developed along with the trend of online shopping. Although online shopping is currently very popular, it does not mean that offline shopping is necessarily abandoned. Conventional payment systems usually require customers to queue at the cashier to make payments after choosing grocery items. Therefore, there is a need for technological innovation that can overcome this. The solution to overcome these problems is by planning to create a Smart Shopping Scanner machine by considering lean project management. Based on the results of the research that has been done, the application of the Lean Project Management method to the Smart Shopping Scanner project planning at PT ABC has resulted in significant improvements. Reduction of project completion time by 33.33%, reduction of component inventory value by 40%, and improvement of team communication by 66.67% show the effectiveness of this method in overcoming waste and increasing efficiency.

Abstract

One concern to support the success of the company is about the performance of each employee. Employee performance has several factors that can influence it, including satisfaction and workload received by each employee in the company. PT. Indonesia Tri Sembilan feels that the performance of its employees is still not optimal and it is felt that it can be improved further, therefore an evaluation is needed on the factors that affect the level of employee performance. The variables used are performance, job satisfaction, and employee workload. Data collection used the questionnaire distribution method and data processing used the IBM SPSS Statistics 26 and SmartPLS 4 applications. Respondents are permanent staff at PT. Indonesia Tri Sembilan with a total of 39 people. From the results of the research, the researchers stated that there was a significant influence between Job Satisfaction and Performance and had a positive effect. Researchers also stated that there was a significant influence between workload and performance but had a negative effect.

Abstract

PT. Duta Beton Mandiri is a company that is part of DUTA BANGSA GROUP domiciled in the Pasuruan regency. PT. Duta Beton Mandiri is a manufacturing company that has been established since 2008 and engaged in the production of building materials or concrete industry which has products such as paving blocks, bricks, ready mix, and precast concrete. PT. Duta Beton Mandiri is still often faced with several defects in their production, especially in paving block products as one of their main products such as easily crushed paving, cracked paving, asymmetrical paving, non-dry/wet paving and also damaged paving which affects quality. The purpose of this study was to determine the presentation of the most dominant defects, the factors causing the defects, and the effects they caused, as well as to propose the appropriate improvements to improve the quality of paving block products. The methods used are Statistical Quality Control (SQC) and Failure Mode and Effect Analysis (FMEA). SQC tools are check sheets, stratification, histograms, paretto diagrams, scatter diagrams, control charts, and cause and effect diagrams. Meanwhile, FMEA is used as a proposal to improve the results of the cause-and-effect diagram. Based on the results of research on SQC, the most dominant defects were Easily crushed paving (38,34%), after that Cracked paving (28,86%), Damaged paving (13,83%), Asymmetrical paving (10,92) and Non-dry/wet paving (8,05%). Based on the results of analysis and calculations on FMEA, it is known that the problem causing disability with the highest RPN value of 384 is the machine factor with the cause of the paving block mold pallet in a dirty or worn position. Recommendations for improvements that can be made are by always checking the condition of the mold pallet before the production process starts on a regular basis.

Abstract

PT. XYZ is a company operating in the shoe industry. In the midsole production process, defects such as burning defects, tear defects, bubble defects and dirty. The aim of this research is to determine the proportion of defects that most frequently occur and the factors that cause defects and to provide suggestions for improving the quality of the Midsole. The method used is Seven tools and Failure Mode Effect Analysis (FMEA). Seven tools include check sheets, statistics, histograms, Pareto diagrams, scatter diagrams, control charts, and fishbone diagrams. Then continue the FMEA analysis to get suggestions for corrective actions. Based on the results of Seven Tools research, it is known that the most dominant defects in the midsole are burnt (38%), then dirty (24.4%), bulging (20%), and torn (17.4%). 6%) ). Based on the results of the Failure Mode Effect Analysis (FMEA) research, it is known that the highest cause of problems with RPN 343 is uneven spraying of the Mold Release Agent. Suggestions for improvement that can be submitted are: Conduct training to workers on how to spray MRA according to standards and determine rest time limits so that the injection machine does not overheat.

Abstract

PT. Selatan Jadi Jaya is a company that produces lead acid batteries for Automotive Car Batteries. During production, problems often arise, namely a fairly high level of product defects. Defects appearing in the burning process include defects in melted tin, burned connectors, bent plates, and torn separators. The purpose of this study is to determine the level of product defects and provide suggestions for improving the quality of battery batteries. Based on the above problems, analyzing the level of defects can use the Seven Tools method and improvement efforts using Failure Mode and Effect Analysis (FMEA). Based on the results of research on Seven Tools that the dominant defect is Connector Burning with a percentage of (33%), then followed by Plate Bent by (26%), then Melted Tin by (24%), and Torn Separator by (17%). Based on the results of the Failure Mode and Effect Analysis research, it is known that the highest RPN value is 200 on tin melt defects. The recommendation for improvement is to adjust the size of the fire according to the procedure.
