Abstract

PT. X is a company that is growing on a large scale and requires process control in product design activities to reduce product defects. The research was conducted with the aim of designing a quality management system in the TTPI department at PT. X. The research focuses on the design of packaging products. The quality management system is designed to minimize the impact of packaging product defects such as poor product functionality, specifications that are not in accordance with demand and others. There were 10 types of packaging defects found. The design is using the DMAIC method and the analysis using 5 whys analysis. 10 packaging defects have root causes, namely measurement errors, color determination, finishing, and different understandings with vendors. The proposed improvements are in the form of a sequential control process from making print files (die line), requesting and reviewing the results of raw designs, semi-finished designs and finished designs from vendors. This improvement proposal is controlled by making SOPs, vendor visits, standardization of measuring instruments and colors. From the suggested improvements, it is considered that can be used as a step to anticipate errors in packaging product specifications and the product design process to be more structured.

Abstract

The problem that exists in the warehouse at PT. XYZ is that there is no material placement layout in the warehouse that supports the FIFO system. The proposal given is to make a layout of material placement in the warehouse by calculating the number of pallets used for each existing material and making a storage and retrieval mechanism that supports the FIFO system will run better. The proposed results can create a more friendly environment for the FIFO system. The ABC method is the main method used to determine the priority of material mapping on the shelves in the warehouse. Then by finding the right order of priority, the calculation to determine the number of pallets used for each material will be easier to find and do. The calculation of the use of pallets that have been obtained will be a reference for the exact location of the material on the shelves in the warehouse, so that the placement of materials in the warehouse will be arranged which creates an environment that makes it easy to find each material to be found and the FIFO system will be easier to run.

Abstract

Performance is influenced by individual ability and work engagement. To improve the ability of its employees, Bank Jatim provides a program called enhancement. Based on the annual report of Bank Jatim, the program assessment given is only limited to pre-test and post-test, which if the post-test score is high then the employee is considered good. Therefore, this study aims to determine whether the enhancement and work engagement programs have an effect on employee performance and a description of the work engagement of Bank Jatim employees. The data used in this study is the KPI balanced scorecard from the perspective of learning and growth and finance and questionnaires distributed to 54 employees in all branches throughout East Java. After all the data was collected, the data was analyzed descriptively using the Structural Equation Modeling (SEM) method to determine the effect between variables. The results of this study are enhancement programs have an impact on employee performance but work engagement has no impact on employee performance. In addition, the description of work engagement shows that the majority of employees who get high engagement scores come from employees who have worked under 5 years.

Abstract

PT X is an automotive company that operates as a manufacturer, assembler, and distributor in and outside the country. PT X is a subsidiary of a multinational company. PT X uses the Just In Time (JIT) principle, so it does not have inventory (zero inventory). PT X produces motorbikes that have a type and color type, where motorbikes produced will be distributed to 29 main dealers. Land distribution will use trucks provided by the transporters, where the trucks used will be regulated in accordance with government regulations. The regulation issued by the government regarding this matter is the rule of Over Dimension Overload (ODOL), where the regulation regulates the dimensions of the trucks used to transport goods. The use of dashboards is a solution to simplify the process of monitoring and controlling the condition of each truck at each main dealer. The use of dashboards for monitoring and control processes is more effective and efficient, because the dashboard can provide a lot of information through just one view. The use of the dashboard increases the progress of improvement, where in January 2019 only 63.13% to 76.55% in April 2019.

Abstract

PT. X is one of the transformer manufacturers in Indonesia. The difference in standard time at each workstation causes a bottleneck on the Core Coil Assembly (CCA) line resulting in late demand fulfillment. Coil LV has the longest processing time among others, therefore a semi automated machine replacement project is carried out to reduce the processing time. The purpose of this research is to find whether replacement on semi automated machine is the best option to be implemented for coil LV workstation. A Break Even Point (BEP) analysis will be used to compare the current state (manual machine) with two alternatives project (combination of semi automated machine). BEP value of alternative 1 is 2,292 units, while alternative 2 is 2,647 units. However, the replacement project is not feasible to be implemented this year because the use of manual machine has a lower cost to meet the demand of 1,601 units. Actually, the optimal capacity for semi automated machines is 8 coil units per shift, so the company can increase the output capacity by reviewing the number of demands.
