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

Maintenance department often has problems with process transfer dies. One of the problems currently being faced is scrap jams that disrupt the production process. The accumulation of scrap results in damage to the product being processed. Therefore, the process must be stopped for 15 minutes to clean the scrap. This research aims to overcome the problem of stuck scrap on LHD dash panel dies by modifying the dies. Identification of causes and effects using a fishbone diagram resulted in the fact that the cause of the scrap jam was the method factor, namely the scrap sutter angle which was too sloping at 80 so that the scrap did not run smoothly and caused buildup in the process area. Dies modification is carried out by adding components to the base plate so that the scrap cutter angle increases. The modification process begins with measuring the components to be modified, followed by creating component designs using CAD software, assembly simulation, docking, machining and assembly processes. After assembly, the scrap sutter angle is measured. There is a change in the scrap sutter angle from 80to 280. The change in the scrap sutter angle makes the scrap material flow smoothly so that no scrap accumulates. From the calculation results it was found that the benefit after improvement was 31,040,000 rupiah per year.

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

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

Angular welding is a commonly utilized technique in the manufacturing industry, particularly in the construction of frame structures. The primary challenge in angular welding is ensuring the accuracy of the angles and the strength of the joints. At Polytechnic STMI Jakarta, the Jig & Fixture Production course aims to train students in using appropriate manufacturing techniques and tools, including welding jigs. The use of welding jigs can improve the precision, efficiency, and consistency of welding results, while also reducing the risk of human error. This study aims to design and analyze a welding jig for angular welding in the context of practical coursework at STMI Jakarta Polytechnic. The research methodology includes a literature review, jig design using CAD software, prototype development, and performance testing and analysis of the welding jig. The expected outcomes of the study are to enhance the quality and efficiency of the angular welding process. Additionally, the designed welding jig provides ease of use for students, thereby reducing errors caused by human factors.

Abstract

The bypass system in spin-on type oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow when excessive pressure occurs. A critical component of this system is endplate-B, which fulfills dual roles: providing structural support and functioning as an interface for oil passage during bypass operations. However, the relatively high material usage and cost associated with the current design of endplate-B pose challenges in manufacturing efficiency. The objective of this study is to minimize the material cost of endplate-B by optimizing its dimensional geometry without compromising its structural and functional performance. The research methodology encompasses dimensional redesign, structural analysis, and performance validation under simulated operating conditions. The findings indicate that strategic dimensional modifications can substantially reduce material usage while preserving mechanical strength and functional integrity. The implementation of this optimized design provides a cost-effective solution for the manufacturing of oil filters and contributes to broader efforts to improve production efficiency in the automotive component industry.
