The manufacturing industry extensively utilizes machining and casting processes for die fabrication. Due to the inherent dimensional inaccuracies and surface roughness of casting, machining is often required to achieve desired accuracy and finish. Traditional computerized numerical control machining relies on individual programming using macro programming or computer-aided manufacturing software for operations such as facing, which can be inefficient and prone to error. This study aims to evaluate and compare the efficiency and accuracy of macro programming and CAM 2.5D in CNC milling specifically for press die manufacturing. Macro programming is used for automating complex and repetitive machining by incorporating variables, expressions, and logic directly to machine whereas CAM 2.5D refers to programming using software in G-code format with capability to work not only two-dimensional planes but also limited vertical movement. Experimental results indicate that CAM 2.5D offers a time-saving advantage by about 2 hours while macro programming allows for greater accuracy in machining. Industries are encouraged to utilize both macro programming and CAM 2.5D to achieve a balance of speed, accuracy, and flexibility, optimizing their CNC machining processes for both large-scale and precision-focused operations.

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%.

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.

The bypass system in oil filters plays a crucial role in maintaining engine cleanliness and performance by allowing oil to flow through the filter when the pressure exceeds set limits. A critical component of this system is the coil spring that controls the bypass valve. In this study, an experimental approach was applied to reduce material cost while preserving performance. We redesigned the spring from four coils of 3.5â€¯mm diameter to three coils of 3â€¯mm diameter, using the same standard hard steel wire SWâ€‘C. The redesigned springs were subjected to a standard impulse test of 250,000 cycles under 7â€¯kgf/cmÂ² pressure and a loading test with deflections from 1 to 10â€¯mm at pressures up to 11â€¯kgf. Results show that the new threeâ€‘coil SWâ€‘C spring meets all performance criteria: impulse life and loadâ€‘deflection characteristics fall within standard tolerances. A direct comparison with the original design demonstrates negligible differences in functional behavior, confirming that material usage and costs can be reduced without sacrificing reliability. These findings offer valuable guidance for the costâ€‘efficient production of oil filter components in automotive engineering.

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.

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).
