Abstract

Based on the REBA analysis, there is a risky operator work postures in the warping work station at PT. Iskandar Indah Printing Textile because they do not use work tools. The assessment of the level of work posture risk by the REBA method gets the result that the highest work element with a final score of 10 is obtained by taking warp yarn at the warping station. This study aims to produce a design tool to reduce the level of work posture risk in warping work station operators. Then the design of tools was carried out by the Pahl and Beitz method to produce three alternative product design concepts. Based on the three ideas, the best plan is chosen by using an Engineering Design Selection, and the result is the second design concept. The selected design is an adjustable trolley with a vertical screw drive system that is comfortable to use and does not cause a bending position on the operator because it has a trolley plate that can be adjusted in height as needed. The use of the trolley causes a decrease in the level of work posture risk from a high-risk level to a small risk level with a final score of 10 to 3.

Abstract

Machine effectiveness is one of the important factors in the production process in a manufacturing company to produce goods. The paving molding machine is one of the machines used to produce black paving at PT XYZ. Based on historical data from the Engineering Maintenance Department, this machine has the highest breakdown frequency which has an impact on the low effectiveness and productivity of the machine. To overcome this problem, an analysis of the effectiveness of the paving molding machine was carried out using the Overall Equipment Effectiveness (OEE) method. OEE aims to analyze machine indicators, which consist of machine availability, performance efficiency, and the quality level of the machine's production. The results of the OEE analysis show that the value of the paving molding machine is 68.18% and is still below the Japan Institute of Plant Maintenance standard of 85%. Six Big Losses is used to determine the low OEE value arising from the production process, on the paving molding machine. From the results of the analysis, two dominant loss factors have the most influence on the effectiveness of the paving molding machine, namely the high value of reduced speed loss (51.92%) and idling and minor stoppages loss (23.69%). These two dominant loss factors are then analyzed using a fishbone diagram to obtain the root causes and proposed solutions.

Abstract

The paving molding machine is one of the machines used to produce black paving at PT XYZ. Based on the historical data from the engineering maintenance department, this machine has the highest breakdown frequency which affected the low performance and productivity of the machine. To solve this problem, the effectiveness of the paving molding machine was analyzed using overall resource effectiveness (ORE) methods. ORE aims to analyze machine indicators, consisting of readiness, availability of the facility, changeover efficiency, availability of material, availability of manpower, performance efficiency, and quality rate. The ORE analyzed result shows that values of performance efficiency of paving molding machine were 64.54% and still below the standards of the ORE. To increase the ORE, a design of autonomous maintenance (AM) was proposed. The proposed design means the operator is given the responsibility to maintain the basic condition of the machine to minimize the damage of the paving molding machine at PT XYZ. The result of ORE analysis, especially in the performance efficiency, will be an input for the engineering maintenance department to make an AM basic design that can be executed by each of the machine's operators. In general, this research’s novelty is to combine the application of the ORE method with the AM basic design, whereas the AM is one of the pillars of total productive maintenance (TPM).
