Abstract

3D printing has rapidly developed as part of additive manufacturing, with Fused Deposition Modeling (FDM) being widely used due to its low cost and ease of operation. PETG is a popular FDM material because of its good mechanical properties and temperature resistance. However, print quality is strongly influenced by process parameters. This study evaluates the effect of FDM parameters on the impact strength of PETG and determines the optimal settings. The investigated parameters were Nozzle Temperature and Wall Thickness, each tested at three levels. The experiments were designed using the Taguchi method with an L9 orthogonal array, producing nine sample combinations. Specimens were printed using a Haltech H-01 3D printer and tested with the Charpy impact method on a GOTECH GT-7045 machine. Data were analyzed using the Signal-to-Noise Ratio with the “Larger is Better” criterion. Results show that Nozzle Temperature has a more significant effect on impact strength than Wall Thickness, indicated by a higher Delta value and greater variation in mean response. The optimal parameters were a 250°C Nozzle Temperature and 2.5 mm Wall Thickness, providing the best mechanical performance and consistency.

Abstract

This study analyzes the effect of optimizing CAD/CAM-based CNC milling parameters to reduce the machining time of a brake pad mold holder. The main issue addressed is the excessive machining duration caused by non-optimal cutting parameters, namely spindle speed, feed rate, and depth of cut. A quantitative experimental approach was employed using the Taguchi method and ANOVA, integrated with CAD/CAM simulation in Autodesk Fusion 360. A 3D model of the brake pad mold holder was developed and simulated to obtain machining time data from nine parameter combinations based on an L9 orthogonal array. The results show that depth of cut has the most significant influence on machining time (87.48%), followed by feed rate (12.49%) and spindle speed (0.03%). The optimal parameter combination was 3500 rpm spindle speed, 175 mm/min feed rate, and 0.6 mm depth of cut, achieving the shortest machining time of 16.633 seconds. This optimization improved machining efficiency by 78.12% compared to the initial condition. These findings confirm that integrating statistical optimization with CAD/CAM simulation can effectively accelerate high-precision manufacturing processes for automotive components.

Abstract

This study aims to analyze the effect of variations in the number and diameter of dimple holes on the stiffness of mild steel plates using the Dimple Dies Triangle Profile forming method. Plate stiffness is important for reducing vibrations, especially in vehicle components. The material used was a 0.6 mm thick galvanneal plate, with dimple diameters of 25 mm and 30 mm, and hole quantities of 16 and 20. Testing was conducted using a Vibroport 80 device to measure natural frequency as an indicator of stiffness. The experimental design employed the Taguchi method with an L4 orthogonal array to analyze the influence of each parameter. The results showed that the number of dimple holes significantly affected the plate’s natural frequency, while the dimple diameter had no significant effect. The optimal combination producing the highest stiffness was a 25 mm dimple diameter with 16 holes. ANOVA and S/N ratio analysis supported these findings, indicating that the number of holes contributed more than 90% to the variation. This research is expected to serve as a reference for developing stiffer and more vibration-resistant metal plate designs, particularly for automotive and other engineering structure applications.

Abstract

The machining process in the manufacturing world greatly influences its quality and productivity. One of the tools in the machining process is a CNC lathe that has parameters for its use process. The process parameters in the CNC machining process are spindle speed, feed rate, and cutting depth. Some aspects that are greatly influenced by process parameters are surface roughness and MRR (Material Removal Rate), which function as efficiency in improving product quality. This study aims to analyse the effect of machining process parameters on surface roughness and MRR on test specimens made of ST 37 material. The method in this study uses the Taguchi method with the aim of increasing productivity and product and process quality. The results of this study show surface roughness based on the use of two types of tools on ST 37 material, with the DNMG 105608-MA tool producing a roughness value of 1.128 µm and the CNMG tool producing a value of 0.865 µm. Meanwhile, the MRR value produced by the DNMG 105608-MA tool is 1,072.8 mm³/s, which is slightly superior to that of the CNMG 120408-MK tool, with an MRR value of 1,032.5 mm³/s.

Abstract

Squid egg chips are one of the typical foods of Bangka Belitung, which are still produced manually, making them inefficient in terms of time and energy. Manual production of squid egg chips in Bangka Belitung faces challenges in terms of efficiency and product consistency. This study aims to design and simulate a squid egg chip molding machine using a systematic approach based on the VDI 2222 method. The stages include needs analysis, concept development, technical design, and evaluation through load simulation using software such as Fusion 360 and MD Solid. The developed machine has an electric motor drive system, pulley and belt transmission, and main components such as a hopper, dough press screw, and dough mold. The simulation results show that the machine design works well and can withstand an operational load of up to 118.87 N, equivalent to ±12 kg. The system can be operated by one person with more efficient production time compared to the manual method. However, the dough cutting mechanism still needs improvement to achieve a uniform and aesthetically optimal chip shape.

Abstract

Laboratory asset management in academic environments is commonly administrative and manual, resulting in low efficiency, accountability, and transparency. This study aims to formulate a digital governance model for laboratory asset management through the application of a web-based information system integrated with QR Code technology and automated notifications. The research method involves system design, real-time asset identification implementation, and user acceptance evaluation using User Acceptance Testing (UAT). The results indicate that QR Code and notification integration not only improves operational efficiency but also establishes a structured and traceable asset control mechanism. User satisfaction exceeding 90% confirms that the system supports transparency and accountability principles in laboratory asset governance. This study contributes an applied digital governance principle that can be generalized to other institutional asset management contexts.

Abstract

Brake pads are generally manufactured using 60% asbestos. Although still widely used, asbestos is not environmentally friendly and poses serious health risks due to its carcinogenic properties, which can cause respiratory disorders when inhaled. Therefore, new environmentally safer innovations are needed, such as phenolic resin matrix composites. This study aims to analyze the effect of matrix percentage and compaction pressure on the density and hardness of phenolic resin matrix composites reinforced with aluminum, brass, silica sand, and boiler fly ash. The powder metallurgy method was applied, consisting of mixing, compaction, and sintering processes. Mixing was carried out using a horizontal ball mill with a Ball Powder Ratio (BPR) of 10:1 at 90 rpm for 4 hours. Matrix compositions of 25%, 29%, and 33% were tested, along with compaction pressures of 5100, 5400, and 5700 psi for 10 minutes. Density testing followed ASTM B962-17, and hardness testing used ASTM E110-14. The highest hardness before sintering was 154 HB, and the highest density was 1.308 g/cm³ at 5700 psi. After sintering, hardness increased to 216 HB and density to 2.120 g/cm³ at 5700 psi with 25% matrix composition.

Abstract

Heat exposure can influence the changes in hardness and flexural strength of composites made from eggshell particles and bamboo fibers. The composite samples were prepared through cold compaction at 5 MPa for 2 hours. The materials were combined based on the following volume fractions: 50% epoxy resin, 10% alumina, 10% graphite, 5% zinc oxide (ZnO), and a 25% mixture of eggshell particles and bamboo fibers. The composite samples were then heated to 200°C for 1 hour. The final step involved curing, which required heating the samples in an electric oven at 150°C for 1 hour. Using a weighting method, the composite containing 25% eggshell particles achieved the optimal result, with a multi response performance index (MRPI) of 42.43. This composite exhibited hardness, modulus of elasticity (MOE), modulus of rupture (MOR), and strain values of 70.24 Shore D, 37.65 MPa, 8.58 MPa, and 0.78%, respectively. Conversely, the sample with 25% bamboo fiber and no eggshell particles demonstrated the highest flexural strength at 12.06 MPa, while the sample containing 25% eggshell particles recorded the highest hardness of 70.24 Shore D.

Abstract

This research aims to design and develop an automatic coffee bean sorting system based on color and weight using the TCS34725 color sensor, HX711 load cell, stepper motor, servo motor, and an Arduino Mega 2560 microcontroller. The system is proposed to address the limitations of conventional manual sorting, which is time-consuming and inconsistent in quality. The methodology includes hardware design, electronic integration, microcontroller programming, and performance testing on coffee beans with various color categories. The TCS34725 sensor is used to capture RGB values for color classification, while the load cell measures the accumulated weight of sorted beans until reaching the predefined target. Experimental results show that the developed system achieves a color detection accuracy of 92.5% and a weight measurement error of 1.8 grams on average. Furthermore, the system is capable of stopping automatically when the target weight is reached. In conclusion, the proposed sorting system enhances efficiency and consistency in coffee bean classification and has potential applications for small industries and coffee-processing SMEs.

Abstract

This study aims to investigate the effect of sintering temperature variations on the hardness and density of brake pad composites fabricated using the powder metallurgy method. The fabrication process consisted of material preparation, powder mixing, cold compaction, and sintering with the weight fraction of matrix and filler wt.% being 40/60, 48/52, and 56/44 wt.%. Powder mixing was carried out using a horizontal ball mill with a ball-to-powder weight ratio (BPR) of 10:1, a rotational speed of 90 rpm, and a milling time of 4 hours. Cold compaction was performed uniaxially at a pressure of 5300 PSI for 10 minutes, followed by sintering at temperatures of 50°C, 60°C, and 70°C for 10 minutes. Density testing was conducted based on Archimedes’ principle in accordance with ASTM B962-17, while hardness was measured using a portable Brinell hardness tester following ASTM E110-14. The highest hardness value of 103.0 HB was obtained at 48% matrix composition with a sintering temperature of 60°C, while the highest density of 1.453 g/cm³ was achieved at 40% matrix composition with a sintering temperature of 70°C. These findings demonstrate that sintering temperature has a significant influence on the mechanical and physical properties of the brake pad composite.
