Abstract

The results of an experiment that used an orthogonal Taguchi method to improve shielded metal arc welding (SMAW) were given. The SMAW method was used to join dissimilar metal of SPHC and St. 30. SPHC material has a low carbon steel content, while St. 30C steels contain a medium amount of carbon steel, which is used for tractor shaft axles. Carbon percentages vary slightly between the two substances. This study aimed to achieve the highest possible quality of tensile strength by utilizing the specified SMAW parameters. SPHC material has a low carbon content, whereas St. 30 steel has a moderate carbon content. This study used the Taguchi experimental method with three input variables and three experimental levels. The SNR ratio is used to evaluate the most optimal SMAW performance. ANOVA analysis is used to evaluate the most crucial parameters in determining the response variable. This research has successfully provided input on the combination of SPHC and St. 30C for SMEs. It operates effectively with a welding current of 133 A, a welding voltage of 9 V, and a filler diameter of 2.0 mm. The S/N ratio analysis found that the welding current, voltage, and filler diameter all had a significant impact on the outcome.

Abstract

The use of press machines in stamping is an important aspect of the manufacturing industry, especially in producing efficient and quality components. This article aims to analyze the cost of the stamping process using mild steel SPCC-SD material measuring 200 mm x 25 mm x 0.8 mm, using two types of press machines, namely 80 tons and 40 tons. Through the cost analysis method, the total cost of the stamping process for the 80-ton press machine is Rp 16,417.4 per 10 pcs, while for the 40-ton press machine, it is Rp 15,028.5, indicating the cost efficiency of the 40-ton press machine is around 8.5%. The tonnage calculation shows that the 40-ton press machine is adequate for the blanking process, with a tonnage requirement of 4 tons, far below the available capacity. These results provide recommendations for the use of 40-ton press machines in the production of steel components on a small to medium scale, considering cost efficiency and optimal performance. This work is expected to increase productivity and cost efficiency in the manufacturing industry, especially at PT GA.

Abstract

This investigation focuses on optimizing the sinker electrical discharge machining (sinker-EDM) process parameters for high tensile strength steel (HTSS), specifically SKD-11, utilizing Box-Behnken Response Surface Methodology (BB-RSM). Sinker-EDM is a commonly used technique in manufacturing moulds, dies, and components for sectors like automotive and aerospace. This process eliminates direct contact between the electrode and the workpiece. However, its low material removal rate (MRR) constrains productivity. This research endeavours to enhance MRR by employing rectangular graphite electrodes. The Box-Behnken Response Surface Methodology (BB-RSM) was utilized to evaluate the effects of pulse current, spark-on time, and gap voltage on MRR. The optimal MRR of 45.49 mm³/min was attained at a pulse current of 16 A, spark-on time of 400 µs, and gap voltage of 45 V. ANOVA revealed that pulse current and spark-on time significantly influenced MRR. In contrast, gap voltage had an insignificant impact. Interaction and surface plot analyses confirmed that high pulse current and extended spark-on time resulted in the maximum MRR. These findings provide valuable insights for optimizing the sinker-EDM process for SHTSS, contributing to enhanced productivity and efficiency in manufacturing.

Abstract

This article presents a study on optimizing Tungsten Inert Gas (TIG) welding on mild steel (SPCC-SD/JIS G3141) with varying thicknesses of 0.6 mm and 0.8 mm. Automobile bodies commonly utilize mild steel with a material thickness ranging from 0.6 to 0.98 mm. The objective of this study was to ascertain the upper limit of tensile-shear strength that can be achieved by utilizing the specific parameters utilized in TIG welding. This study utilizes a three-level experiment and incorporates three input variables in the Taguchi experimental optimization method. The advantage of this approach lies in its ability to yield comprehensive outcomes while minimizing expenses, as it can be adapted to the resources available. An additional benefit is that this approach can be implemented in a multitude of industrial situations.The study's input variables are welding current, argon gas flow rate, and electrode diameter. Utilizing a continuous flow of argon gas of 12 LPM (liter per minute), a welding current of 55 A, and an electrode diameter of 1.6 mm, the maximum mean T-S strength of 3457.13 N was achieved. The ANOVA revealed that the flow rate, welding current, and electrode diameter had a per cent contribution of 50.07%, 26.89%, and 23.04%. The flow rate was the parameter with the most significant impact on the influential variable. The welding current and the electrode diameter do not significantly affect the response. The findings indicate that by adjusting the parameters to the optimal level determined by the Taguchi method, the S-N ratio for T-S strength increases by 9.30%, and T-S strength increases by 12.42%. The findings of this study offer a thorough comprehension of enhancing the TIG welding approach and can be further refined by incorporating additional variables.

Abstract

The car body repair process is integral to vehicle development and structural repair. The primary objective of this study is to enhance the quality of thin material welding utilized in automobile body repair. The impetus for this research stems from the necessity to improve the structural integrity and longevity of thin materials prone to deformation throughout the welding procedure while minimizing distortion. This study aims to identify optimal parameters for the tungsten inert gas welding (TIG welding) process on thin materials, particularly for automobile body rearrangement. The Taguchi method conducted the experimental analysis of variations in welding parameters, including electrode diameter, gas flow rate, and welding current. Adjusting TIG welding parameters to their optimal values significantly improves weld joint direct tensile load (DT-load) and overall structural quality, according to the findings of this study. ANOVA analysis and the S-N ratio indicate that gas flow rate and welding current are significant determinants of the quality of welded joints in thin materials. This research contributes to a better understanding of the optimal parameters for fusing thin materials, particularly in automobile body repair. The automotive industry can use these findings as a guide to enhance the quality and strength of welding processes, which are critical to the structural integrity of vehicles.

Abstract

Tungsten Inert Gas (TIG) welding uses a tungsten electrode and argon or helium gas for shielding. It offers excellent shielding, stable arc, adjustable heat input, minimal spattering, and attractive welds. Widely used in various industries, especially for thin materials like galvanized sheets, TIG welding can be challenging for dissimilar materials like galvanized steel and low-carbon steel due to their different melting points. Studying optimal welding parameters is crucial for success. This research focuses on TIG welding of SPCC-SD (JIS 3141) and SGCC (JIS 3302) materials with thicknesses of 0.6 mm and 0.8 mm. The electric current was varied at 45, 50, and 55 A, whereas the gas flow rate was varied at 12, 15, and 18 LPM. The weld bead diameter was varied as 5, 8, and 10 mm. Subsequently, the welded samples were subjected to tensile testing using a SHIMADZU AGS-X 10Kn STD E200V tensile testing machine. The data from the tensile tests were analysed using S/N ratio analysis and Analysis of Variance (ANOVA) with the assistance of the Minitab software. The results of the S/N ratio analysis indicated that the most optimal parameters were an electric current of 55 A, flow rate of 15 LPM, and weld bead diameter of 10 mm. Conversely, the ANOVA revealed that the weld bead diameter significantly influenced the tensile load in TIG welding of SPCC-SD (JIS 3141) with SGCC (JIS 3302) materials, accounting for up to 44.42% of the variation. Following the weld bead diameter, the flow rate and welding current contributed to 21.93% and 16.41%, respectively.

Abstract

The increasing number of motor vehicles has led to higher fuel consumption, especially among two-wheeled vehicles, contributing to elevated emissions of hydrocarbon (HC) and carbon monoxide (CO). This study investigates the potential of lemongrass oil (LO) as natural additive to reduce exhaust emissions from RON 92 fuel. The LO was extracted via maceration and characterized by its physical properties, including density (0.893 g/mL), viscosity (5.30 mPa.s), and boiling point (222 °C), consistent with pure LO standards. The additive as then blended into RON 92 fuel in concentration of 10 mL, 15 mL, and 20 mL per 1000 mL of fuel to determine its optimal performance. Results showed that a 20 mL addition yielded the highest reduction in HC and CO emissions, respectively 49.76% and 46.24%. Furthermore, engine performance improved, with power increasing by 0.27 HP and torque by 0.21 Nm within an engine speed range of 5200-5700 rpm. These outcomes suggest that LO enhances combustion efficiency and reduces emissions. The findings highlight the potential of LO as an environmentally friendly fuel additive and supprt ongoing efforts to develop sustainable alternatives to conventional fossil fuels in Indonesia.

Abstract

An answer to the worldwide need for solutions to food security, data fusion technology that combines climate data with satellite imagery greatly improves the accuracy of agricultural yield predictions; this study intends to examine the advancements, methods, and key contributions of this area. By sifting through 62 papers pulled from Scopus, this research employs the SLR methodology. Document type, data source, open access, subject area, and year of publication (2020–2024) are some of the categories filtered through by Boolean keywords in the selection process. To assess patterns in publications, the efficacy of machine learning models, and key contributions, bibliometric analysis was performed. An upward tendency in publication has been identified by the analysis, particularly beyond the year 2023. Integrating geographical and temporal data has been a great success with machine learning models like Random Forest, Random Forest, and Gradient Boosting. Data resolution, integration of data from several sources, and a real-time framework are still missing pieces to the puzzle when it comes to generalizing research outcomes. More complex data fusion approaches, multiregional datasets, and advanced machine learning models to back more accurate agricultural predictions are all things that this study notes as needing additional investigation in the future. To further innovate agricultural yield prediction, multidisciplinary collaboration is also crucial.
