Abstract

One of the materials used in the building process is sand particle. Sand with uniform size is generally obtained from manual sifting processes that require a lot of human power and long sieving time, so a sand sieving machine is needed to minimize the use of human power and sieving time. The design is focused on sifting sand manually into sieving using a machine. The design of the machine uses design software to create a picture of the arrangement and working drawings of the components of the sand sieving machine. Based on the results of the trials that have been carried out, the machine can sift 5 kg of sand for 1.02 minutes and for 10 kg of sand can be sifted for 1.30 minutes.

Abstract

Fused Deposition Modeling (FDM) is a 3D Printing technique used to print products using filaments as material. The printed product has ideal geometric characteristics if it has meticulous size and perfect shape. One type of material that can be processed using 3D Printing FDM is flexible material. Research in terms of dimensional accuracy has been carried out on PLA and ABS materials. While research using flexible materials is still rarely done. From these problems, we need a study to get the process parameter settings on a 3D Printer machine that is optimal in obtaining dimensional accuracy using flexible materials. The research was carried out using the Prusa model DIY (Do It Yourself) 3D machine with FDM technology. The material used is Eflex type flexible filament with a diameter of 1.75 mm. The process parameters used in this study are flowrate, layer thickness, temperature nozzle, speed printing, overlap, and fan speed. Cuboid test specimens measuring 20 mm × 20 mm × 20 mm. Process parameter optimization using the Taguchi L27 Orthogonal Array method for dimensional accuracy testing.

Abstract

Pengelasan merupakan bagian yang sangat penting dalam pengembangan dan pertumbuhan industri karena memang memiliki peranan dalam rekayasa, reparasi dan konstruksi. Pengelasan SMAW (Shielded Metal Arc Welding) adalah proses penyambungan dua buah material atau lebih yang terbungkus menggunakan elektroda sebagai energi panas untuk mencairkan material tersebut. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dan cacat las yang timbul dengan variasi arus sehingga didapatkan hasil pengelasan yang optimal dari 3 amper yang diuji dengan menggunkan elektroda E6013 diameter 3,2 pada sambungan fillet posisi pengelasan 3F. Penelitian ini menggunakan metode eksperimental dengan bahan yang digunakan baja St 37 dengan variasi arus 90A, 100A, dan 110A. Dari penelitian yang dilakukan tidak didapatkan hasil pengelasan yang optimal dimana dari masing-masing amper yang diuji masih terjadi cacat las. Cacat yang ditimbulkan pada ketiga amper tersebut disebabkan busur, sudut elektroda, dan arc length yang melebihi batas normal dan juga dipengaruhi kecepatan pengelasan. Dari ketiga variasi amper yang digunakan didapatkan hasil pengelasan yang dominan tidak terjadi cacat las yaitu pada amper 90, sedangkan pada kaki las amper 100 menunjukan hasil kaki lasan yang baik.

Abstract

The process of making fried onions is carried out in several stages until they become fried onions that are ready to be consumed, starting from peeling the onion skin, slicing, frying, slicing, and packing. From the results of a survey conducted on service partners, the process of peeling onion skins is still manual, namely peeling it using a knife one by one. It takes approximately 4 hours to peel 15 Kg of raw shallots which is done by 2 employees, and the process takes a lot of time. In order to increase the production of shallots, a shallot peeling machine was developed to speed up the stripping process. Partners will receive appropriate technology in the form of a shallot peeler and training in the process of using the machine and maintaining the machine. In addition, a monitoring and evaluation process is also carried out to measure the level of success and constraints on the machines that have been used by partners. After the development of the shallot peeling machine was developed, the partner's production productivity increased, the machine functioned properly and was able to peel as much as 5 kg of shallot skin in 10 minutes or 30 kg/hour.

Abstract

Carburizing is a heat treatment process on the outer layer of the material using carbon as a compaction component. The working principle of this heat treatment is to put carbon around the workpiece when heated with the aim that the carbon will diffuse to the outer layer of the workpiece. In this research, a carburizing process will be carried out with a variety of catalysts on St37 steel. The catalyst variations used were 100% charcoal and 0% lime, 90% charcoal and 10% dolomite lime, 85% charcoal and 15% dolomite lime, 80% charcoal and 20% dolomite lime, 75% charcoal and 25% dolomite lime. To determine the impact of catalyst variations on the carburizing results, a hardness test will be carried out. From the results of research that has been done that a mixture with a variation of 85% charcoal and 25% dolomite lime has the highest average hardness value with a value of 21.5 HRC and the variation of a mixture of charcoal and dolomite lime has a significant effect on the hardness value.

Abstract

Friction welding is one of the metal joining methods, by utilizing the heat generated from the physical contact of two metals in the form of friction that occurs continuously on the two metals to produce a welding joint.  This research aims to find out what phenomena occur in the connection between AISI 1040 and Brass. The materials used are AISI 1040 solid cylinder with a diameter of 16 mm and brass solid cylinder with a diameter of 16 mm. This research uses experimental method. The friction time used is 6 minutes, 7 minutes, and 8 minutes with a variation of pressing distance of 3 mm, 4 mm, 5 mm with a rotating speed of 1000 rpm. The free heat process of 200 ℃ was carried out on AISI 1040 before the welding process. From the time variation and pressing distance variation that has been carried out in this study, the results obtained from the two materials do not occur. There are several phenomena seen after the welding process such as the occurrence of plastic deformation in brass and the formation of a brass thermoplastic layer attached to the surface of AISI 1040, in the time variation of 6 minutes and 7 minutes the brass thermoplastic attached to AISI 1040 is small and thin, while in the time variation of 8 minutes the brass thermoplastic layer attached to AISI is quite a lot and thick but no connection has occurred. This friction welding method is likely to connect the AISI 1040 material with brass by increasing the friction time performed.
