Abstract

The use of automatic sorting systems in industry plays a crucial role in saving time and reducing manual labor through automation. The main challenges are the high error rate and slow manual sorting processes. This research aims to design and develop an automatic sorting conveyor system using Arduino technology and pneumatic actuators to enhance sorting efficiency and accuracy. The proposed solution is a system capable of detecting and sorting objects based on size with very low error rates, thereby increasing productivity and reducing human error. The design and development of this system involve creating a 3D model of components such as the conveyor frame, belt, motor, pneumatic actuators, and sensors, and integrating them into a complete system. Testing was conducted with seven differently sized test objects to evaluate the system's performance in detecting and sorting objects based on size and height. Input and output voltage measurements ensure performance in line with the expected specifications. The research results demonstrate that the developed automatic sorting conveyor system effectively sorts objects with high accuracy. The system can detect and sort objects based on size with a 0% error rate, reducing the time required for the sorting process compared to manual methods. The use of pneumatic actuators and appropriate sensors ensures consistent and reliable system performance. The test results indicate that the system can be integrated into various industrial applications to enhance production efficiency. The developed automatic sorting conveyor system successfully improves the efficiency and accuracy of the sorting process in industry. It shows significant potential for reducing human error and increasing productivity, making it a practical solution for various industrial applications.

Abstract

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.

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

Basically, every job will have its own safety hazard risk factors, especially the automotive industry. Automotive industry work practices have Occupational Safety and Health (K3) risks for all workers in the work environment. Potential hazards that will be faced include exposure to chemicals, infections, allergies, electricity and physical such as slipping, falling, being scratched, stabbed, and hit which depend on the type of activity carried out in the area. Seeing aspects of the physical work environment such as the layout of practice equipment, personal protective equipment, work clothes, cleanliness of the room, lighting, irrigation, air conditioning in the work space is very important in creating a safe environment free from the risk of accidents or occupational diseases. This is what drives the Abdimas team to encourage socialization and implementation of K3 and 5R at the May Car Bodyworks Workshop with the aim of increasing efficiency, productivity, and quality in work activities at the Workshop. This activity uses a descriptive qualitative method, where the technique of collecting data information is selected in a specific way, and uses observation methods with interviews and documentation and is analyzed in the application. The results obtained are in the form of a report on the implementation and application of the 5R program in the Workshop and can implement the 5R and K3 culture programs.

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

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 3.5 mm diameter to three coils of 3 mm diameter, using the same standard hard steel wire SW‑C. The redesigned springs were subjected to a standard impulse test of 250,000 cycles under 7 kgf/cm² pressure and a loading test with deflections from 1 to 10 mm at pressures up to 11 kgf. Results show that the new three‑coil SW‑C spring meets all performance criteria: impulse life and load‑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 cost‑efficient production of oil filter components in automotive engineering.
