Abstract

The Walasoji Shredded Fish (AIW) Business Community was located in Rappang Village, Panca Rijang District, Sidenreng Rappang Regency, South Sulawesi, started its activities in 2012. The partner community is a home industry, initially having around eight members, but now there are only three people. In the shredded production process, partners still use traditional tools, partners cannot determine the exact profit, the packaging of shredded products is still simple without a brand, without a health department permit number, and without a halal certificate from MUI. The problems faced by partners are: how to improve the quality and production capacity, how to know the profit for sure, how to increase the market share of shredded walasoji fish. Based on the problems above, the solution is to improve production methods and processes using machines, provide training and counseling on management, as well as a simple accounting bookkeeping system, assist in branding and packaging equipment, assist in obtaining permits from the health department, and MUI halal certificates. Through this PKM, it is hoped that the capacity and quality of AIW produced by partners will increase, and can be marketed through markets, shops, supermarkets and supermarkets. The methods that will be applied are assistance with production equipment, and packaging, training and counseling on management, and a simple accounting system, assisting in obtaining permits from the health department, and MUI halal certificates. The output targets to be achieved in this activity are scientific publications in national journals or proceedings of national seminars, and published in print or online mass media. With the publication, it is targeted that AIW, which is only known in Rappang, can be widely known, both regionally and nationally after this PKM is implemented.

Abstract

This paper proposed a new algorithm for fault location and classification using wavelet based on Clarke’s transformation to obtain the fault current. This novel method of fault current approach is studied by comparing the use of the glide path of the fault voltage. The current alpha and beta (Current Mode) were used to transform the signal using discrete wavelet transform (DWT). The fault location was determined by using the Clarke’s transformation, and then turned into a wavelet, which was very precise and thorough. The most accurate was the mother wavelet Db4 which had the fastest time and smallest error detection when compared with the other wavelet mothers. In this study, the Clarke’s transformation is also compared with the Karenbauer’s, which has produced results with similar error percentage. The simulation results using PSCAD / EMTDC software showed that the proposed algorithm could distinguish internal and external faults to get the current signal in the transformation of a signal fault.

Abstract

The joint for two different materials (AA5052 and AA6061) can be done by the Dissimilar Friction Stir Welding (DFSW) process. Therefore, this study was conducted to analyze the mechanical properties of dissimilar welding joints. In this study the DFSW process uses a tool with a shoulder Ø 17.8 mm and a cylindrical pin Ø 5 mm. FSW blocking is done on conventional milling machines with 1300 rpm, 1950 rpm and 2850 rpm tool rotation variations, while the welding speed variations are 43 mm / min, 130 mm / min and 240 mm / min. The results of mechanical properties testing showed the highest hardness value obtained was 55.3 HBN at 1300 rpm with 240 mm / min feeding, the highest tensile strength occurred for 1300 rpm and 240 mm / min feeding at 123.51 MPa. The fracture of the tensile test results generally occurs in the HAZ area and the AA5052 base metal Nugget. Investigation results show that the DFSW connection of aluminum alloy material AA 6061 and AA 5052 adapt is well connected, but in terms of general strength the tensile strength of the joint (HAZ and Nugget) is smaller than the tensile strength of the base metal. This DFSW connection adaptation is applied to connections that do not accept load or tensile strength due to the load received by the connection not to exceed the maximum tensile strength of base metal AA 5052

Abstract

Nowadays, the metal forming process in the welding machinery and machinery industry is developing very rapidly, especially in the bending process. The buckling process is a metal formation which generally uses sheet plates or rods from both ferrous and non-ferrous metals by bending, which in the bending process will cause a stretching or stretching on the neutral axis of the field along the bending area and producing a straight bending line. Appropriate technology machines have been widely used to increase productivity, efficiency, and effectiveness in the production process for community efforts. One of the appropriate technologies that can be applied in buckling is a tool equipped with a press tool. Press tool is one type of tool for the formation, cutting and bending of products from the base material of sheet plates whose operation uses a press machine. In this study, a V brake bending tool has been produced which has a capacity that is bending line length 300 mm, bending width 33 mm, spring height 110 mm, free step distance 19 mm, spring load received 263,820 N and material capacity that can be bent is a thickness of 3 mm, the punch angle used is 85⁰ with a punch radius used which is 1.5 mm while the die angle is 85⁰
