Abstract

This research identifies and addresses the waste problem at Yanto's Truck Seat Service, with the main focus on measuring seat dimensions and marking the leather and foam. This waste occurs because seats with the exact dimensions are often re-measured, resulting in inefficient use of resources. To solve this problem, we developed a tool in the form of a mall or jig that facilitates the measurement of upholstery dimensions and the cutting of leather and foam. Through this improvement, we reduced the number of work elements before the improvement from 21 to 20. The process of measuring seat dimensions and cutting leather and seat foam was eliminated from the production process. As a result, the production time was significantly reduced by 884 seconds. Before the improvement, the production time reached 5276.33 seconds per unit; after the improvement, it became 4392.33 seconds per unit. This improvement also positively impacts daily production, which can now reach the target of 3 units per day. Takt time in the production process before the improvement was 4800 seconds per unit, multiplied by 3 units, which is 14,400 seconds for 3 units. With this improvement, the production time is faster than the takt time. Future research can consider improving the layout of Yanto's Truck Seat Service to further increase the efficiency of the production process, given that there is still potential for improvement in reducing the time required to move between processes.

Abstract

Productivity is the most vital part of the food industry as it is one of the priority industries in Indonesia. PD. Saluyo is an industry that produces tofu, which needs to increase production efficiency to meet market needs. The problem in the tofu production process is the high waiting time during soybean soaking. The approach used in this research is lean manufacturing by mapping the process using Value Stream Mapping so that Value Added, Non-Value Added and Necessary Non-Value Added activities can be mapped. Further, Value Added, Non-Value Added and Necessary Non-Value Added data processing is weighted in VALSAT to determine the most significant waste and mapped through PAM. The mapping results obtained a VA of 3,29%, NVA of 90,64% and Necessary Non-Value Added of 6,06%. Based on the results of the VALSAT calculation, the most significant waste is found in time waiting and unnecessary motion. These results are re-mapped in PAM for further analysis using the Cause-Effect Diagram. The analysis results of PAM and the Cause-and-Effect Diagram proposed improvements to change the soaking process method using hot water and create a new SOP to adjust to the proposed production process. The results of the proposed improvements can increase the value added by 0,07% from 3,29% to 3,36%.

Abstract

Currently, almost every household in Indonesia has a motorbike, this is certainly a business opportunity. One of the most important components of a motorbike is the tire which functions to reduce vibration and protect the wheel from wear and damage. The business environment operating in the automotive sector needs to create high-quality goods or services to increase customer satisfaction. Costs in the company's productive processes must be reduced to achieve effectiveness. The object of this research is the XYZ Tire Workshop located in East Jakarta. In a day, the XYZ Ban workshop can provide up to 25 to 30 motorbike tire changes. Meanwhile, the workforce on duty is only 2 mechanics and the quantity of tools is limited. This causes delays and makes customers have to wait quite a long time before their motorbike can be worked on. The Single Minute Exchange of Dies (SMED) method which is included in lean tools is the key to reducing set-up process time. In general, SMED aims to standardize and simplify operating processes. The SMED technique is used as an element in Total Productivity Maintenance (TPM) in various studies to achieve lean manufacturing. Based on research data, the set-up time before implementing SMED was 177 seconds. After implementing the SMED method, the setup time was 126 seconds. This shows that the SMED method can reduce set-up time by 51 seconds.

Abstract

The development of production demands in the automotive industry has resulted in an increase in the need for various shapes and types of metal materials. Components used in automotive industrial production require the strength and durability of metal materials. The products produced in this sector are very diverse, including engine components, vehicle body parts and various vehicle accessories. To be able to meet customer demands for quality and efficiency, adequate production process support tools are needed, of course, such as dies. This tool is very suitable for making products from sheet metal with the same shape and in large quantities in a relatively short time. However, in making printing equipment (Dies) it does not require operation, it requires precise calculations so that accurate process results will be obtained, especially in calculations and clearance accuracy. Efforts to improve quality and efficiency in the product manufacturing process, for this reason, an analysis and improvement of the clearance of the cut results on SPC440 material with a thickness of 1 mm for the Member Floor Side Inner Lh product was carried out. The results of the improvement in the clearance of the part were able to optimize the clearance value from 0.06mm to 0.075mm

Abstract

This study aims to improve the efficiency of tofu production at Haji Ripit tofu factory through the application of Lean Manufacturing principles. The analysis was conducted using the Value Stream Mapping (VSM) method to identify and overcome time waste in the production process. The results showed the main problems, namely waste waiting and waste motion. Waste waiting was identified in the process of moving the stew to the filter, while waste motion was caused by the inefficient arrangement of the filter. To overcome the waste waiting, a modification was made to the boiling furnace by adding a hole for the output of the stew. This change successfully reduced the cycle time of the pouring process from 2000 seconds to 400 seconds, with a cycle time difference of 1600 seconds. In addition, to address waste motion, a re-layout was proposed by unifying the workbenches in the molding, cutting, and packaging processes. The results of the re-layout proved the reduction of movement time from molding to cutting process from 10 seconds to none. This research makes an important contribution in the context of improving efficiency and productivity in tofu factories, and the results can serve as a reference for similar industries in improving their operational performance through the implementation of Lean Manufacturing.

Abstract

This research aims to reduce waste in the R-WaterFilling Service Small and Medium Enterprises (SMEs) by applying the principles of Lean Manufacturing, specifically 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke). The main problem identified is the length of service time caused by waste, which often hinders the achievement of daily sales targets. Through the Lean Manufacturing approach, we mapped and identified waste through Value Stream Mapping and Process Activity Mapping. The results of Value Stream Mapping show that R-Water's service process lead time is 822.22 seconds. Waste identification revealed the existence of waste motion in filling gallons of water. Based on these findings, root cause analysis was conducted using the Lean Manufacturing 5 Whys approach. The improvement phase was based on the root cause and applied the 5S principles. This improvement's results significantly impacted, reducing the lead time to 750.2 seconds. This research makes an essential contribution to minimizing waste in the service process, which in turn improves operational efficiency and helps achieve set sales targets.

Abstract

The automotive industry in Indonesia is one of the priority industrial sectors that is developing quite rapidly. The automotive component production process in industry generally includes the molding process, welding process, assembly process, and automotive component quality control process. During the welding process,the ST-03 electroda used by PT ST-03 electroda repairs were carried out using a CNC Milling machine. The electroda repair process is carried out one by one with a total time of 120 minutes or 2 hours per day. The large amount of time required for the repair process makes loading parts hampered. Therefore, a jig machining design was carried out to speed up the electroda repair process. The ST-03 jig machining material used is SS 400 iron. The product design was carried out using CAD software and then simulated using CAM. The simulation results show that the use of jig machining can reduce production time by 98%or 118 minutes. This is because in one set up you can repair 20 electrodas so that in 1 day you only need to do 3 set ups. The profit obtained from using the ST-03 jig machining electroda is 166,500,000 rupiah per year.

Abstract

PT HMG is a manufacturing company that uses injection moulding machines to produce plastic components for the electronics, automotive and engineering industries. The problems found at PT HMG are that the finished goods are not placed in an orderly manner or that the goods are not neatly arranged. The placement of these goods is still mixed with goods that have run out, so the process of moving goods is not optimal and the risk of picking inappropriate goods is higher. This has an impact on delivery errors and the sub-optimal process of moving goods can cause delays in delivery to the customer. Dedicated storage is a layout design method for storing goods where the storage location is fixed. This method uses throughput as areference when positioning goods so that goods with a high flow of movement are prioritised to minimise the time it takes to move goods to I/O points. The difference in the total distance to the I/O point for the proposed layout is 17,809 metres, or 9% of the previous layout. With this layout improvement, the company is able to reduce the waste caused by material handling activities in the finished goods warehouse.
