Abstract

Utilization of solar energy sources is one of the alternative energies to save fossil energy. The use of solar panels has been widely implemented in homes, buildings and open fields. Therefore, the largest energy source is on the beach, because the coastal area has an area without obstructions of sunlight. With this background, this study aims to create an offshore solar panel tool. The method used is to review literature studies, manufacture of offshore solar panels, testing on the beach and data analysis. The test results show that the average power versus time (Wh) produces the lowest value of 9.3679 Wh and a medium value of 23 Wh and the highest value of 26 Wh. The type of battery used is FLA (Flooded Lead Acid) with a voltage of 12V and a capacity of 5 Ah. The influence of the lowest and highest values ​​is the level of sunlight conditions on the beach from sunrise to sunset. Offshore solar panels can float well and receive good light energy sources.

Abstract

The persistent challenges in material forming processes arise from recurrent issues encountered during the deep drawing process, particularly involving cracks and deviations from standard thickness dimensions. This article investigates the deep drawing process using both experimental and numerical methodologies. The experimental approach employs a 40-ton capacity power press machine, while the numerical method utilizes the ABAQUS student version software. SPCC-SD (JIS G3141) is the selected material for producing a Dop-pipe 2-inch diameter pipe cap in both approaches. Noteworthy findings include the highest positive and negative correlations observed in elements E 46 and E 48, with values of 0.715 and -0.933, respectively. Minimal disparities, averaging around 4.6% for all components, were evident between the experimental and numerical methodologies. The numerical approach yielded predictive results identifying potential issues in elements E 47 and E 48. This observation did not reveal instances of tearing failure but instead showcased an increase in thickness due to a higher axial force between the dies and punched-in components. The study successfully and accurately predicted product thickness for all components, presenting a contrast with outcomes obtained through the experimental method. Furthermore, this research advances the deep drawing process, extending its applicability to broader material forming applications and ultimately enhancing overall production process efficiency.

Abstract

Industrial developments, especially in the manufacturing and construction sectors, recognize L-hanger ducting as a critical component in HVAC (heating ventilation and air conditioning) ducting systems, which play a role in supporting and stabilizing air ducts. The L-Hanger ducting manufacturing process involves a series of stages, such as shearing, blanking, piercing, trimming, and bending processes. This research focuses on the design and simulation of dies and punches for piercing, blanking, and bending processes using 1.6 mm-thick SPCC-SD material. The aim of this research is to design and analyze progressive dies in order to increase the efficiency of the production process. A comprehensive calculation of the forces involved in the shearing, blanking, piercing, trimming, and bending processes is required in order to predict press machine tonnage requirements to support the production process. This research applies theoretical and numerical validation approaches. Theoretical analysis is used to calculate the overall forces, which are then compared with numerical results and verified through an experimental approach. By understanding and optimizing the design of progressive dies, it is hoped that we can increase the production efficiency of L-hanger Ducting and expand knowledge in the field of metal forming, contributing to the metal forming industry and supporting the development of science.

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

Ultrasonic welding is the joining of materials using of heat generated from high frequency mechanical movements. Known as an efficient process in many applications, such as in textile, packaging and automotive industries. One of the materials that can be joined using ultrasonic welding is thermoplastic material because there is no polymer degradation found in the product after the welding process. In most practices, parameters determining for ultrasonic welding machines uses a trial and error method, several parameters are determined to vary, such as welding pressure, welding time, holding time, drop speed and trigger pressure. To determine the correct variation of values, the Taguchi method is the right choice, determining the variable matrix is ​​very easy, commonly used, and many studies have proven that the Taguchi method is reliable. In this research, the product to be studied is a medical device, which uses thermoplastic polymer as its material. This research has produced the best variable variation of ultrasonic welding machine parameters: welding pressure of 20.00 psi; welding time of 0.21 seconds; holding time of 0.16 seconds; horn descent speed of 3.00 seconds; and trigger pressure of 4.00 psi. The defective products on appearance had reduced to 0.07% from the previous 1.08%.

Abstract

The material manufacturing process involving the deep drawing process is often challenging in small and medium industries. That is due to the many complicated parameters that must be overcome during the process. The deep drawing is a complex steel forming process because it involves blank dimensions, dimension/height ratio (D/H ratio), and die/punches tolerance (D/P allowance). Failure to identify blank dimensions and D/H ratio will result in defects in the production process, such as tears and wrinkles. This service aims to help MSMEs overcome common failures in production processes involving deep drawing. This community service article discusses technology dissemination to small business groups (UKM) for the deep drawing process in producing R-ornament #3D40x40 components involving these three variables. R-ornament #3D40x40 is produced using SPCC-SD material with a thickness of 0.8 mm. The participatory action research (PAR) method approach assists MSMEs in optimizing blank dimensions, D/H ratio, and D/P allowance simultaneously with partners. Identification of a D/P allowance of 1.41 mm has eliminated wrinkle defects in the product. Identifying deep drawing parameters has helped MSMEs overcome the production process so that tearing and wrinkle defects do not occur.

Abstract

The deep drawing is a complex steel forming method involving blank dimensions, dimension/height ratio (D/H ratio), and clearance between die and punch (D/P allowance). Failure to identify proper blank dimensions and D/H ratio can lead to production defects such as tears, while failure to recognize the correct clearance can cause wrinkles. This article discusses technology dissemination to Small and medium-sized enterprises (SMEs) for the deep drawing process in producing R-ornament components #3D40x40, considering these crucial parameters. R-ornament #3D40x40 was manufactured using SPCC-SD material with a thickness of 0.65 mm. The Participatory Action Research (PAR) method was employed to collaboratively optimize blank dimensions, D/H ratio, and dies/punch (D/P) allowance with partners. The optimization of blank dimensions successfully eliminated the need for the trimming process, resulting in reduced investment costs in dies and die setup by IDR 15 million and 2.16 million, respectively. Identifying a D/H ratio of 1.32 successfully eliminated tear defects and determining a D/P allowance of 0.87 mm on each side eradicated wrinkle defects in the product. This article contributes to Goal 9 of the Sustainable Development Goals (SDGs), specifically focusing on the Small and Medium-sized Enterprises (SMEs) sector.
