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.

Abstract

Velg merupakan bagian dari unit kendaraan yang berperan sebagai penopang beban saat kendaraan berhenti dan juga sebagai pengantar gerakan putar dari mesin untuk memindahkan kendaraan. Jika terjadi kerusakan pada velg, hal tersebut dapat menjadi risiko serius bagi pengemudi kendaraan tersebut. Penelitian ini bertujuan untuk mencari nilai deformation total, von mises stress, Stress intensity dan deformation total dynamic pada desain velg dengan variasi jumlah jari-jari dan menggunakan tiga jenis material yang berbeda. Metode penelitian yang digunakan adalah analisis eksperimental dan simulasi dilakukan dengan menggunakan perangkat lunak simulasi static structural ANSYS Workbench 2023. Setelah menjalankan simulasi, hasil penelitian dapat diperoleh hasil bahwa setiap ukuran ketebalan jari-jari dan jaraknya dapat mempengaruhi hasil data variabel. pada velg tipe 2 atau velg dengan jari-jari 10 mendapatkan hasil simulasi yang paling buruk diantara dua lainnya. Jadi, dapat disimpulkan bahwa material magnesium lebih baik diantara alumunium dan baja karbon. Dan setiap desain dapat mempengaruhi kekuatan dari material itu sendiri.

Abstract

X-ray diffraction (XRD) data and the Scherrer equation were utilized to analyze the crystallite Size of titanium dioxide (TiO2) in a solution of ethylene glycol (EG) and distilled water. The XRD analysis was conducted using a Rigaku Miniflex 600 instrument with an X-ray wavelength of approximately 0.15046 nm. The examination yielded the full-width half maximum (FWHM), which was subsequently examined using the Scherrer equation. This experiment employed TiO2 with a purity level of 99.8% and a crystal Size of 30 nm. The analysis revealed that the average crystallite Size of TiO2 in the sample is 19.45 nm, with the highest measurement at about 30.38 nm. The Spearman correlation equation was employed to validate the outcomes. The Spearman's correlation coefficient between the FWHM variable and the crystallite Size of TiO2 nanoparticles is -0.958. These findings shed light on the crystal structure of TiO2 under these conditions. These findings lend support to the use of TiO2 in a variety of nanotechnology applications. However, more research is needed to understand fully how crystallite-Size TiO2 nanoparticles work in different settings and to find the best ways to prepare samples, including understanding the specific phase and how it affects the stability of fluids. This research contributes significantly to the understanding of the properties of TiO2 in a solution of distilled water and EG, as well as to the characterization of nanomaterials, with particular emphasis on issue 9 of the SDGS Goal concerning industry, innovation, and infrastructure.
