Assistance of Handicraft Small Business in Increasing Capacity
Get PDFThe micro, small and medium enterprises (MSMEs) is important in building the nation’s economy. Our SMEs partners are owned by Architecture Students of Universitas 17 Agustus 1945 Surabaya, they are Keranting and Beelovedthings. Keranting runs in Fashion products with the application of Ecoprint. Ecoprint itself is a process of transferring patterns or colors into fabric/leather/paper media using natural materials and dyes. Meanwhile, Beelovedthings is engaged in handicrafts which are used for souvenirs and merchandise. The partners problems are un-consistent stock of products and they have not reached the turnover target because they are still doing conventional marketing. To overcome these problems, we have to obtain consistent supply of raw materials, availability of adequate equipment that can support the production process, the consistent availability of various types of products, content creation and selection of digital marketing platforms, as well as increasing e-commerce and social media traction. The results of this program are not only in the form of stock fulfillment, but also more varied content creation which can attract more customers. The availability of various digital marketing platforms makes it easier for buyers to reach MSME products with paid promotions carried out on digital marketing platforms to increase eCommerce traction
The Influence of SMAW Welding Current Variation on Tensile Strength, Corrosion Rate, and Microstructure of ST 42 Steel for Inner Bottom Plate Material in Ships
Get PDFSteel is currently widely used in the industrial world. Due to its versatile uses, the development of steel science has also broadened, leading to improved steel processing methods. Welding is a process of joining two pieces of metal using heat. Steel, containing carbon, is prone to oxidation and rust. The aim of this study is to determine the influence of welding current variations on tensile strength, corrosion rate, and the micrographic structure of ST 42 steel. The research method employed is experimental. The welding current variations used are 70 A, 85 A, 100 A, 115 A, and 130 A. In this study, the highest average tensile stress was found at 130 A, measuring 519.20 MPa. For tensile strain, the highest values of 7% were observed at 115 A and 130 A. The highest modulus of elasticity was obtained at 115 A, with a value of 102.18 GPa. The highest corrosion rate occurred in specimens with 70 A, with a value of 0.19 mm/year (good), and the lowest corrosion rate was at 130 A, with a value of 0.10 mm/year (excellent). The micrographic structure testing results showed a decrease in the ferrite phase with each increase in current, while the pearlite phase increased. It can be concluded that the best welding current for ST 42 steel is at 130 A, due to its high tensile strength and low corrosion rate
