Abstract

This study aims to determine the various effect of heat input due to varied electric current on microstructure of the weld joints and the bending strength of 2 dissimilar metals (aluminum alloy 5052 and galvanized steel) with Al-Si 4043 as filler. This experimental research was worked out by varying the strength of the current which can then be calculated into a heat input. The current inputs applied were 30.8 J / mm (70A), 35.2 J / mm (80A) and 39.6 J / mm (90A) while the protective gas flow rate used is 14 liters / minute. This study showed that the increase in heat input greatly affects the shape of the weld area microstructure, i.e. the microstructure and bending strength. Greater heat input due to higher current can melt larger area, so that the join process occured better. The highest bending strength at 9.05 Mpa was achieved for heat input at 39.6 J / mm or strong current of 90 A. The weakest bending strength at 8.88 Mpa was achieved for heat input at 35.2 J / mm or a strong current of 70 A.

Abstract

In this paper, the effect of welding parameters on the shear strength of Al-PVC hybrid structures was discussed. This Research developed welding parameters in the form of Plunge Depth, heating time, and clamping frame materials. By these different parameters would result in different shear strength of welded materials. Following optimization of the process, a detailed comparison of the properties and microstructures of two different materials (meranti wood and ASTM A36 Steel) would affect to different values of thermal conductivity. The Aluminum used was Al 1100, which was welded by using a friction stir spot welding method with Polyvinyl Chloride (PVC). In this study, by the different heating times, the shear test was carried out with the ASTM D3163 standard. In this study, it was found that the maximum temperature of Aluminum occurs during the 2nd second of the welding process and then decreased in the 5th second until 60th second. However, the optimum shear strength found at 20th second. Following heat transfer and degradation materials, the 2mm plunge depth has a higher temperature and higher shear strength than 1,5mm plunge depth. Differences in the response of the two depth were attributed to the difference in mechanical interlocking. This study found that the ASTM A36 clamping frame maximum shear load of 182.4 N is higher than meranti wood frame of 125.5 N. Differences in these value are attributed to the differences of the thermal conductivity, which meranti wood had a lower thermal conductivity than ASTM A36. These have findings significant implications for the commercial application of welding hybrid structures. The best way to take advantage of the benefit of AL-PVC Structure Hybrid for friction stir spot welding would appear to be 20 second heating time, 2mm plunge depth with ASTM clamping frame.

Abstract

Batik products provide the second largest contribution of 20-30 percent of gross domestic product (GDP) in the creative economy sub-sector. In the sub-district of Dermo, some of its residents live from agriculture, handicrafts and the batik industry. From the team's observations, it was found that Dermo Village was the leading village for batik producing. The Batik industry is a home industry that can support a portion of the population of the Dermo Village. The development of batik is very much influenced by the design abilities of the batik makers. The batik groups in Kelurahan Dermo are mostly housewives, so the problem of design is a problem. But no less creative and innovative, handicrafts have become one of the largest creative industries in Indonesia, although they are not as sophisticated as today's electronic devices or gadgets, handicrafts are still one of the alternatives or choices of society to satisfy and please their hearts. Moreover, Indonesian handicrafts are truly unique and different, supported by many natural resources such as rattan, wood, bamboo and human resources in Indonesia, Indonesian people are freer in producing and creating handicraft products in any form, so that businesses like this can has progressed very rapidly and made Indonesian handicrafts can be shipped abroad. However, the time needed to make batik is very long, especially if people order a special motif that does not have many guidelines or examples of batik designs. So this makes batik craftsmen reluctant to accept large quantities of typical batik orders. These can reduce the confidence of consumers who want to make typical batik in large quantities. For this reason, the team tried to develop batik designs with distinctive motifs which were manifested in the form of prints. From the design development that has been done by making batik stamps with typical motifs of the City of Kediri, this is able to reduce the time for batik production and make batik craftsmen more confident in receiving orders in larger quantities than before. So that with this motif stamp, the batik production of Dermo Kediri Village can increase.

Abstract

The corrosive coastal environment will result in a high corrosion rate for any equipment installed there. This is due to the constant exposure to saltwater, high humidity levels, and strong winds. Therefore, it is crucial to use corrosion-resistant materials and regularly maintain the equipment to ensure its longevity in such an environment. One method to reduce the rate of corrosion is to pay close attention to the manufacturing parameters of these components, one of which is the face milling process. The aim of this study is investigating the effect of face milling process with different dept of cut using minimum quantity lubrication method with corn oil as a renewable vegetable cutting fluid. In this study AISI 316L stainless steel was face milled using HAAS VF-2 CNC machine. The depth of cut is varied between 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm. The results demonstrated that the greater the depth of cut, the greater the surface roughness value that will be generated. It is resulting in increment in the corrosion rate value.

Abstract

Galvalum has become an inevitable part of Darul Muttaqin Batu Islamic Boarding School construction. The ease of access, affordability, and simplicity of installation have led to most buildings within the boarding school using galvalume. However, professional galvalume workers are still employed when it comes to the structure and construction at the boarding school. As a result, the boarding school has to incur high costs to construct or create equipment made from galvalume. In addition to the above-mentioned issues, the students are a valuable human resource that can be utilized to create equipment from galvalume. However, because the students are not yet familiar with how to cut, assemble, and create kit from galvalume materials, training is essential to provide them with additional skills alongside their religious studies at the boarding school. This endeavor involves the contribution of equipment for galvalume material manufacturing and training on assembling galvalume materials according to the boarding school's needs. Through these activities, it is hoped that knowledge will be transferred from the university/instructor to the students. Consequently, this not only equips the boarding school but primarily provides the students with skills so that when they graduate from the boarding school, they have the skills to lead a decent and self-sufficient life.
