Abstract

This study analyzes the effect of variations in cooling and extrusion speeds on a single screw extruder plastic machine to produce filaments. The method used is a factorial Design of Experiment (DOE) with a two-way ANOVA test, where the cooling speed (8.7 m/s, 11.8 m/s, 14.3 m/s) is varied using the inlet valve on the blower and extrusion (20, 30, 40 rpm) is varied using a tachometer. The testing process includes measuring the dimensions and weighing the filament after the extrusion process, and the data is processed using Excel and Minitab-21. The results show that increasing the cooling speed decreases the dimensions and density of the filament, while increasing the extrusion speed increases the dimensions and density of the filament. The interaction between the two is also proven to be statistically significant with 0.000 on dimensions and 0.014 on density ≤ 0.05 (p-value ≤ 0.05). The optimizer response determined the optimal combination at a cooling speed of 14.3 m/s and an extrusion speed of 20 rpm for a target dimension of 1.75 mm, while the optimal parameters for density were at a cooling speed of 8.7 m/s and an extrusion speed of 40 rpm, resulting in the highest density of 0.246 g. These recommendations are expected to improve the efficiency and quality of filament production.

Abstract

In the manufacturing industry, surface roughness is one of the important quality parameters in machining results, especially in the vertical milling process. This study aims to optimize the concentration of soluble oil coolant and feed rate on the surface roughness of ST 37 steel using the Taguchi method. The material used is ST 37 steel with dimensions of 10 mm × 17 mm × 50 mm, processed using a Dixon XZ7550CW vertical milling machine with a 10 mm diameter HSS endmill. Variations in the concentration of Randocut 500 coolant (3%, 5%, 10%) and feed rate (24, 40, 65 mm/min) were tested with fixed parameters such as a depth of cut of 0.5 mm and a spindle speed of 580 rpm. Surface roughness values (Ra) were measured using a surface roughness tester and analyzed using the Taguchi method and ANOVA. The results showed that a coolant concentration of 5% and a feedrate of 24 mm/min produced the lowest surface roughness (2.24 µm) with the highest S/N ratio (-7.01 dB). ANOVA analysis revealed that feed rate had the most dominant influence (62.4%) on surface roughness, followed by coolant concentration (36.8%). The optimal combination to minimize surface roughness is a concentration of 5% and a feed rate of 24 mm/min..

Abstract

This study analyzes the influence of solar panel type and solar charging technology on the charging performance of lithium-ion batteries. Two types of solar panels, monocrystalline and polycrystalline, were tested alongside two charging technologies: Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM). Experiments measured voltage, current, and charging time parameters, and calculated the State of Charge (SoC) as a performance indicator. The results showed that the combination of monocrystalline panels with MPPT technology achieved the highest charging efficiency and shorter charging times compared to other combinations. These findings indicate that selecting the appropriate panel type and solar charging technology significantly affects lithium-ion battery charging performance, providing valuable considerations for portable solar energy system designs and renewable energy applications.

Abstract

Reverse engineering is the process of reproducing or recreating an existing model—whether it is a component, subassembly, or complete product—without relying on the original design documentation or CAD data. One of the key techniques that supports this process is photogrammetry, a method that utilizes a series of photographic images to identify, capture, and reconstruct the geometry of physical objects in three dimensions. Photogrammetry offers advantages such as low cost, portability, and non-contact data acquisition, making it a valuable tool in various engineering and industrial applications. This study aims to analyze the influence of two important factors—namely, the number of photographs taken and the intensity of lighting—on the dimensional accuracy or deviation of 3D models produced through photogrammetry-based reverse engineering. A quantitative experimental approach was used, where both variables were systematically varied to evaluate their effect on model precision. Data analysis was conducted using a Two-Way ANOVA factorial test to determine the statistical significance of each factor and their interaction. The experimental results revealed that using 54 photographs yielded the lowest average dimensional deviation among all tested conditions, although the difference was not statistically significant. Similarly, variations in light intensity showed no statistically significant effect on accuracy, but visually, an illumination level of 200–250 lux tended to provide more consistent and stable model outputs. No significant interaction was found between the two variables, indicating that they operate independently in affecting model accuracy. Overall, the combination of 54 photographs and a light intensity of 250 lux was visually identified as the most effective setup. The findings of this research contribute to the optimization of photogrammetry workflows in reverse engineering, offering practical insights for producing high-quality CAD models for use in design, prototyping, and manufacturing processes.

Abstract

Photogrammetry is a technique for measuring and modeling three-dimensional objects by utilizing digital imagery from various perspectives. In the context of reverse engineering, this technique serves to duplicate, reconstruct, and analyze the dimensions of physical objects with a high degree of accuracy. The main advantage of photogrammetry lies in its ability to capture the details of the shape and texture of objects without the need for physical contact. However, the quality of photogrammetry scan results is greatly influenced by a number of technical factors, especially lighting and camera sensor sensitivity (ISO) settings. Variations in these two parameters can cause deviations or dimensional deviations in the resulting 3D model. This study aims to quantitatively evaluate the influence of lighting intensity and camera ISO setting on dimensional deviation in photogrammetry scan results. The research method used is experimental, where the dimensions of the scanned object are compared to the original dimensions using precision measuring instruments. The results showed that both the lighting level and the ISO setting had a significant influence on the accuracy level of the 3D model. The ideal lighting intensity range was found to be in the range of 125–150 lux, where shadows and light reflections could be minimized. Meanwhile, the use of low ISO (around 200) is able to produce cleaner image textures and minimize noise, resulting in smaller dimensional deviations. Additionally, the interaction between moderate lighting and low ISO is proven to provide the best scanning accuracy. This combination is able to maintain a balance between image quality and surface detail of the object. These findings not only provide practical recommendations regarding the regulation of scanning conditions, but can also serve as a guideline for industry practitioners and academics in improving the quality of reverse engineering results. With a proper understanding of lighting and ISO variables, the photogrammetry process can be optimized to produce more accurate and efficient 3D models.

Abstract

Photogrammetry is an important technique in the reverse engineering process to reconstruct 3D images without requiring initial design data. This technique allows the creation of digital models of physical objects through processing a series of two-dimensional images. This study aims to analyze the effect of camera ISO settings and shutter speed on the level of dimensional deviation in the reconstructed 3D model. The method used is an experiment with a quantitative approach, involving a series of software for the 3D image reconstruction process, mesh structure preparation, and digital dimension measurement. The ISO variations used in the image capture were 250, 400, 500, and 800, while the shutter speed variations applied included 1/125 second, 1/100 second, 1/50 second, and 1/25 second. The test object was a cylinder with an actual diameter of 50 mm. The obtained 3D model results were compared with the actual dimensions through a Two-Way ANOVA statistical analysis to test the significance of the influence of both variables. The results showed that both ISO and shutter speed had a significant effect on the dimensional deviation of the 3D model. The combination of camera settings with ISO 500 and shutter speed 1/125 second produced the smallest deviation, while the combination of ISO 800 and shutter speed 1/25 second gave the largest deviation. The coefficient of determination (R²) value of 99.02% indicates that the statistical model used is very strong in explaining the variation of deviation. This research contributes to the optimal setting of camera parameters to improve the accuracy of photogrammetry results in reverse engineering applications.

Abstract

Photogrammetry is a widely used technique in reverse engineering that utilizes photographs taken from multiple angles to capture the geometric structure and surface textures of physical objects. This method has gained popularity due to its cost-effectiveness and time efficiency compared to more expensive alternatives such as laser scanning. However, one of the primary limitations of photogrammetry is its susceptibility to dimensional deviations that can affect the accuracy of the resulting 3D model. Among the influential parameters, the number of photos taken and the camera’s shutter speed play a crucial role in determining the level of geometric precision. This study aims to analyze the effect of the number of photos and shutter speed on dimensional deviation in 3D reconstruction results. It also seeks to determine the optimal combination of these parameters to enhance model accuracy in reverse engineering applications. The research method used is an experimental approach, in which variations of photo quantity and shutter speed are applied during image capture. The resulting photographs are processed into a 3D model using Computer-Aided Design (CAD) software and compared with the actual dimensions of the object under study. The findings reveal that both the number of photos and shutter speed significantly influence dimensional accuracy, both individually and interactively. The best results were obtained using a combination of 48 photos with a shutter speed of 0.020 seconds, yielding the smallest deviation of 7.6 mm. In contrast, a combination of 36 photos with the same shutter speed produced the highest deviation at 10.6 mm. ANOVA analysis yielded a p-value < 0.05 and an R² value of 94.21%, confirming the importance of selecting appropriate imaging parameters for accurate photogrammetry outcomes.

Abstract

This study discusses the effect of valve weight and clearance on the efficiency of a hydraulic ram pump, with a focus on optimizing water discharge efficiency in the Sumberingin Tourism Area, Wringinsongo Village, Tumpang, Malang Regency. The method used in this study is an experiment with variations in valve weight consisting of 10 kg, 11 kg, and 12 kg, as well as valve clearances varying between 16.5 mm, 24.5 mm, and 32.5 mm. The results showed that the combination of a valve weight of 10 kg and a clearance of 16.5 mm produced the highest water discharge efficiency, namely 69.7 liters per minute, with an optimal efficiency of around 33%. In the optimization process, the application of Design of Experiment (DOE) revealed that a valve weight of 11 kg and a clearance of 16.5 mm can produce a maximum discharge efficiency of 63.155 with a desirability value reaching 0.7671. These findings indicate that proper settings on valve weight and clearance can contribute significantly to increasing the efficiency of a hydraulic ram pump. This research provides valuable insights into improving the performance and reliability of hydraulic ram pumps in rural water distribution systems. Understanding the influence of these variables is expected to yield more effective solutions for water resource management, particularly in areas requiring efficient irrigation systems. Furthermore, this research also opens up opportunities for further research on hydraulic ram pump optimization by considering other factors that can influence the efficiency and performance of the overall water distribution system. It is hoped that the results of this research can serve as a reference for the development of more efficient and environmentally friendly hydraulic ram pump technology, as well as supporting the sustainability of water resource management in rural areas.

Abstract

Disc discs are the main component in a motorcycle braking system that functions to convert kinetic energy into heat energy through friction. The geometric design of the disc, including the diameter and number of holes, affects the effectiveness of braking as well as the heat dissipation ability. This study aims to analyze the effect of variations in diameter and number of holes on disc discs on braking distance and disc temperature. The research method used was an experimental method with three variations in disc diameter (190 mm, 220 mm, and 260 mm) and three variations in the number of holes (30, 36, and 42 holes). The test was carried out through a controlled braking procedure at an initial speed of 40 km/h on flat road surfaces with stable weather conditions. Braking distance data is measured using ultrasonic sensors, while disc temperature is recorded with a high-accuracy infrared thermometer. The results showed that the diameter of the disc disc had the most significant influence on the braking distance. The larger the diameter, the greater the braking moment resulting so that the stopping distance becomes shorter. The number of holes in the disc also plays a role in heat dissipation because the holes enlarge the heat dissipation area. However, the increase in the number of holes tends to slightly increase the braking distance due to a reduction in the area of frictional contact field. The most optimal configuration is found on a 260 mm diameter disc with 42 holes, which results in the shortest braking distance of 8.25 meters and the lowest temperature rise of 4.47°C.  Statistical analysis using Two-Way ANOVA confirmed that the diameter and number of holes had a significant effect individually, but there was no significant interaction between the two. These findings confirm that the selection of the right disc dimensions is critical to improving braking performance, thermal efficiency, and rider safety.

Abstract

This study aims to analyze the effect of the combination of oil viscosity and shock load on the compression characteristics of telescopic shock absorbers on motorcycles, which include depth, time, and compression speed parameters. The experiment was carried out using two levels of oil viscosity, namely 10 cSt and 15 cSt (equivalent to SAE 10W and SAE 15W), as well as two shock load variations, namely 40 kg and 50 kg, which were dropped vertically from a height of 30 cm. Compression depth measurements were carried out using a slow-motion camera at a speed of 240 fps and the results were validated using Kinovea software. Meanwhile, the compression time measurement is carried out with a stopwatch, and the compression speed is calculated from the results of the comparison between the compression depth and the compression time. The experimental data were analyzed using Minitab software with the Two-Way ANOVA method to determine the influence of each variable on response. The results of the analysis showed that oil viscosity and shock load had a significant influence on the compression depth, while the viscosity of the oil also significantly affected the compression speed. However, neither the viscosity of the oil nor the shock load exerted a significant influence on the compression time. To support the results of the experiment, a mass-spring-damper system theory model approach was used, which represents the dynamic behavior of shock absorbers. This model helps to explain the compression response to changes in fluid and load parameters theoretically. Based on the analysis of experimental results and model simulations, the optimal combination that provides the best performance is found in the use of oil viscosity of 10 cSt (SAE 10W) with a shock load of 50 kg.
