Abstract

The redesign of the die design in the blank-pierce process for the RH/LH quarter panel extension reinforcement product was carried out using field observations to obtain actual data. The production process consists of five stages: blanking, piercing, restriking, bending and forming. Meanwhile, in the redesign process, the RH/LH quarter panel extension reinforcement product is evaluated in the blanking and piercing die processes. Cycle time analysis after the tool design has been redesigned shows the potential for increasing efficiency by reducing process time. MPP data is used as a guide for die design with relevant machine specifications, die size and materials. Machine pressure and tonnage calculations were carried out for the current die design and the revised version, showing significant improvements in production efficiency. The die redesign was carried out to increase output per stroke and to use more sophisticated automation processes. The results of this research show that improved die design can increase production efficiency and productivity by reducing the number of strokes required and properly adjusting machine capacity.

Abstract

This study aims to apply the Single Minute Exchange of Die (SMED) method in reducing setup time on a 350T capacity molding machine at PT HMG. The data collection results showed that the frequency of mold changes reached 70 times a month, with the average time required for mold changes before the implementation of SMED 173 minutes. After the implementation of SMED, the mold change time was successfully reduced to 64 minutes, reflecting a decrease of 63%. The implementation of SMED was carried out through several stages, including converting internal activities to external ones, which aimed to reduce machine downtime. Optimization of the remaining activities was also carried out, such as reducing the temperature drop time on the barrel and hot runner, which previously took 15 minutes, now only 5 minutes. The final results showed that machine downtime cost savings reached Rp11,200,000 per month after the implementation of SMED, with total downtime costs decreasing from Rp30,274,999 to Rp19,074,999 per month. This study proves that implementing the SMED method can significantly improve time efficiency, reduce production costs, and create more efficient operational standards. The findings provide a solid basis for further development in industry manufacturing practices.

Abstract

PT Ganding Toolsindo was faced with the problem of high automotive component die setup times. The main cause of the high setup time is the process of tightening and releasing the bolts which is done manually. The aim of this research is to design a tool for clamping dies which functions to help speed up the bolt installation process, so that the setup time for automotive component dies is reduced. The method used in this research is field observation followed by the die clamping design process. Design planning begins by drawing the object using CAD software based on the results of load calculations and determining the dimensions of the dies themselves and the press machine as well as selecting the dies material. Furthermore, proof was carried out that this die clamping design could reduce dies setup time using movement analysis with a pre-determined time study Measurement Time Method (MTM) method, where the results showed a time saving of 92.4%.

Abstract

Penerapan metode Single Minute Exchange of Dies (SMED) pada mesin press SEYI SN2-300 di PT Ganding Toolsindo bertujuan meningkatkan efisiensi pergantian dies dalam produksi. Tahapan program mencakup analisis proses, sosialisasi, pelatihan, pendampingan, serta evaluasi penerapan SMED. Implementasi menghadapi kendala pada identifikasi aktivitas internal dan eksternal serta adaptasi teknisi terhadap metode baru. Dengan analisis dan pelatihan intensif, beberapa aktivitas internal setup berhasil diubah menjadi eksternal, sehingga waktu setup turun menjadi 29,58 menit dari sebelumnya 35,73 menit. Selain mengurangi downtime, SMED mendukung sistem operasional yang lebih terstruktur, meningkatkan standar kerja, dan kualitas produksi. Evaluasi menunjukkan efektivitas SMED dapat terus ditingkatkan dengan alat bantu tambahan. Implementasi ini tidak hanya meningkatkan efisiensi, tetapi juga membangun budaya kerja disiplin dan berkelanjutan yang mendukung efisiensi waktu, pengurangan biaya, dan peningkatan kualitas produksi.

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.

Abstract

This study investigates the operational performance and sustainability of two urban minibus routes D41 (Gandaria–Cibinong) and D37 (Cibinong–Kampung Rambutan) in the Depok–Bogor region of Indonesia. Using field observations and GPS-assisted time tracking, three indicators were analyzed: passenger load factor, operational headway, and travel time. Results show that while both routes exceeded the government’s 70% load factor benchmark during peak hours, performance dropped below 50% at midday. Headway generally remained within the acceptable range of 2–5 minutes, but D37 exhibited the shortest intervals during morning peaks. D37 also experienced prolonged travel times, often exceeding 80 minutes. These findings highlight the inefficiencies of informal public transport systems, particularly their inability to scale services to match fluctuating demand. This study proposes a low-cost, data-driven framework for assessing route efficiency and supports the integration of informal routes into broader transport planning. The results are relevant to urban mobility reform in developing cities.

Abstract

Plastic injection molding is a method of forming a product that uses plastic (Polymer) as the main material. The resulting product must have as few defects as possible because it will reduce the quality value and customer satisfaction. In this study, the mold was made for the Front towing bumper cover product with the design and simulation stages. The simulation process uses Moldflow Software to identify possible product defects that occur with variations in melt temperature of 200, 240, and 280 (°C). The result obtained in this simulation is the optimal melt temperature for producing products in the injection molding process by selecting a temperature of 240°C. This temperature is the most optimal because it has faster fill time and cooling time, with an optimum percentage of 25% compared to the temperatures of 200 and 280 (°C). In potential defects such as air traps, weldlines, and shinkmarks, a temperature of 240 (°C) has fewer potential defects than 200 and 280 (°C).

Abstract

Modern manufacturing industries demand high efficiency and consistent product quality, especially in metal forming processes such as stamping dies. An accurate punch and die design essential to ensure the success of bending operations, particularly for metal-based products like forks. This study aims to evaluate the structural reliability of punch and die designs through a static simulation approach as a quality confirmation method prior to manufacturing. The methodology includes die geometry design, selection of SKD11 tool steel based on its mechanical properties, and stress analysis using SolidWorks software under a static load of 35 tons. The stress distribution was analyzed using the Von Mises method, and the Factor of Safety (FOS) was calculated as a design safety indicator. Simulation results show that the maximum stress on the die was 9.91 × 10⁷ N/m² and on the punch was 1.01 × 10⁸ N/m², both well below the yield strength of SKD11 (6.88 × 10⁸ N/m²). The FOS values of 3.47 for the die and 3.26 for the punch confirm structural safety. Validation through trial dies and 3D scanner measurements indicated dimensional deviations within the acceptable tolerance range. This approach effective for improving design accuracy and production efficiency in stamping die manufacturing.
