Abstract

PT. Intidaya Dinamika Sejati is a company engaged in the distribution of pedrogals, roots blowers, becker vacuum pumps, as well as technical consultants for service services for various products, such as vacuum pumps, roots blowers, air end compressors, control panels, and air locks for all brands. There are five divisions in PT. Intidaya Dinamika Blower division, Vacuum division, Fabrication division, Rewinding division, and Industrial Repair division. Fabrication Division is one of the largest divisions in PT. The Power of True Dynamics. In Fabrication division there are several wastes that can reduce the productivity of making medical vacuum pump. The wastes that exist in PT. Intidaya Dinamika Sejati Fabrication division: motion, waiting, transportation, defect, and extra processing. Researchers designed value stream mapping as a reference for improving the medical vacuum pump production process. The suggestions made for process improvement, briefing, stricter supervision and assessment, worker training, setting the hand stacker before the welding process, use of measuring tape, use of phosphating liquid to wash tanks, the uses of spray putty, and change the order of processes. Finally, the researcher made a future value stream mapping to describe the situation after the proposal.

Abstract

PT X is a global No. 1 in the world. To remain the best, companies need to maintain and increase productivity. This is because productivity is a measure of the success of a process. The purpose of this study is to find out the causes of low productivity and make efforts to reduce the gap between planning and actual. The approach used in this research is DMAIC. It was found that the factors causing the productivity target not to be achieved were due to the gap in working time/machines running and the number of workers who did not match the plan with the actual. This gap is caused by the efficiency of the production process which is still not on target. This causes the output of the production process is not as planned. This impact resulted in the amount of time and labor needed to be not in accordance with what was planned to achieve the desired productivity. The suggestions for improvement are the visual control display design, plan of action, and control plan sheet. This proposal is considered to be able to assist planning and production to control the productivity of the production process.

Abstract

PT. Intidaya Dinamika Sejati is a company engaged in design, engineering and service in the industrial and general business sectors in Indonesia. The services offered are for various products such as vacuum pumps, air-end compressors, control panels, roots blowers, and air locks. The two main products produced at PT. Intidaya Dinamika Sejati, namely the medical system and root blower. Waste is any form of activity that does not add value to the product (Ridwan et al. [1]). The results of observations and interviews with companies show that waste of time and energy caused by several factors occurs at PT. Intidaya Dinamika Sejati. Observations were made to obtain cycle time, value stream mapping and waste analysis. The results of the analysis show that there is waste waiting, motion, transportation and defects. Waste analysis is carried out with the help of the value stream mapping tool. Proposals are given to reduce the waste that occurs. The proposal is expected to reduce defects, unnecessary movement of workers and waiting time.

Abstract

Productivity is an ability to carry out activities that produce an output or work in accordance with the specified quality. However, there are problems that cause the company's goals to be less achieved. Output is determined by planning, resources, etc. Planning explanations can lead to various financial, production, and other problems. This research was conducted because of the difference between the planned productivity target and the actual productivity of the production conditions. The company uses the SAP software to plan the use of labor and calculate the productivity of the assigned workers, and the company will make adjustments on the production floor if there is an excess or shortage of labor. Because the difference in the amount of productivity and use of labor can be identified based on the data on the difference between the planned and actual productivity. To optimize planning, it is necessary to analyze the root of the problem using the DMAIC method and 5 whys analysis. By finding the root cause of the problem, the company can immediately take corrective action.
