Abstract

PT. X is a furniture company whose production system applies a make to order system. The production process of PT. X's products starts from raw materials, namely wooden boards which are processed into finished goods such as tables, chairs, and cabinets. The problems that occur in PT. X is the process of fulfilling customer orders that often experience delays. This happens because there is no scheduling system in the Woodworking Processing department, causing the production output to not reach the required production capacity. Therefore, this research was conducted to increase production output at PT. X, especially in the Woodworking Processing department. Increased production output is done by minimizing the time of the production process with the scheduling method of Campbell Dudek Smith (CDS) and Palmer. Based on the results of the research that has been done, the scheduling process using the Campbell Dudek Smith (CDS) and Palmer method is able to produce a proposal with a reduced makespan value of 32.07 seconds per wooden plank when compared to the initial conditions. By implementing a proposal that has a smaller makespan value, it is expected to increase production output so as to reduce the occurrence of delays in order fulfillment.

Abstract

Changeover is the time needed to prepare for the next product production. CV. Sinar Baja Electric has a high changeover time due to the many product variants. A high changeover indicates a low level of machine availability. This study aims to increase the availability value of the company. This research will use OEE and SMED methods. Overall equipment effectiveness is a way to monitor and improve the efficiency of the manufacturing process. There are 3 factors that influence the calculation of OEE, namely availability, performance, and quality. Single Minute Exchange of Die (SMED) is a method used to reduce changeover time when a machine or equipment is undergoing a product type change. The purpose of using this method is to reduce changeover time. Based on the results of data processing, it was found that the proposed improvements for reducing the standard range from setting the glue timer and air pressure, improving the time sequence of production scheduling based on the size and type of glue, reducing the variant of glue used, setting the location and increasing the number of scales, making a structured work instruction setup machine. Estimated proposal to get a changeover time reduction of 55.2%

Abstract

Production activity in industry can operate better if the production machine effectivity increases. The main problem identified in PT. Multipack Unggul is ineffective machine usage. One of the causes is the occurrence of downtime. Data indicates the duration of downtime happens in October 2021 for 69,133 hours (1,819%), November 2021 for 103,5 hours (2,806%), December 2021 for 90,1 hours (2,192%), and January 2022 for 96,433 hours (2,679%). That problem urges total productive maintenance (TPM) design and implementation in the company. Processed data shows that there are 7 machines with OEE value that do not reach the standard, i.e., corrugator, flexo I, II, IV, glue I, II, and III, despite a machine above the standard, i.e., flexo III. The MTBF and MTTR value of each machine are also calculated. The significance of the maintenance item is determined by the MTBF value. After analyzing the root causes, improvements plans and implementation are done. Several improvements have performed and showed an increase or indication of an increase in the period time of maintenance items on corrugator, flexo, and glue machine.

Abstract

The changeover time that occurred in one of the departments at companies had a pretty big time. Therefore, Improvements are needed in order to reduce the changeover time. The method that will be used to reduce the changeover time is by using the DMAIC method and assisted by the Single Minute Exchange of Dies (SMED) method. The study began by observing the machine that had the longest changeover time. The observations were carried out using the SMED method and analyzed using the SMED method as well. The results of the analysis will be a proposed Improvement for the machine in question. The results of the proposed Improvements are divided into two, some can be applied directly, and some cannot be applied directly due to certain conditions. Implementations that can be carried out directly will be observed and controlled so that they can run as expected, while those that cannot be carried out directly will only be in the form of ideas or prototypes as an illustration for the company.

Abstract

PT X is a company that works in manufacturing electrical components. One of their plants called Y plant has a mini warehouse that functions as a buffer for inventory between the main warehouse (A plant) and the production line on Y plant. One of the challenges currently present at Y plant’s mini warehouse is the high value of  consignment-Kanban inventory maximum Kanban capacity (K-max), reaching up to $200,073 for 445 part numbers. This problem is caused by the imbalances between certain part numbers’ K-max quantity and their actual average daily usage in real life. The proposed solution for this problem is to recalculate their K-min and K-max quantities by using the latest data that represent their real life conditions. The proposed solution is then implemented to 339 out of 445 consignment-Kanban type part numbers. This implementation brings reduction to the total K-max quantity by 43.96% reduction, and reduction to the total K-max value by 43.98%.

Abstract

Human resource planning in the company is needed so that the company can prepare workers before starting the production process. Planning errors can cause financial problems, production problems and other problems. This research was conducted due to the difference between planning and actual labor requirements for compact, jar and lipstick products. Planning the company's workforce needs using the help of SAP software, and the company will make adjustments on the production floor if there is an excess or lack of labor. Changes in the number of workers also make changes in labor productivity. Therefore, differences in the number of workers can be identified based on differences in the value of productivity that is planned and actual. To optimize planning, it requires root cause analysis using the DMAIC method and 5 whys analysis. By finding the root cause of the problem, the company can immediately take corrective action and improve their company.
