Abstract

Sports shoe products produced by (MSME) actors in Mojokerto have not demonstrated theperformance of products received by the public, this is based on the design of shoes done still sourced from thedesign of sports shoes owned by well-known brands that are marketed around mojokerto, research is done todayaimed to design competitive sports shoe products, with the best quality as well as with the latest models that suitthe needs of consumers. The design of sports shoe products is carried out today using Quality FunctionDeployment (QFD). The result of the design of shoe products that are ed has product specifications namelytopline / collar made of elastic and soft, eyestay/strap hole with a certain amount, patterned and embossed upper,flexible and soft midsole, toe box with hole point as air circulation, lace shoe adjusted to skin color, logo designused embossed, detachable insole and elastic insole, flexible wedge, jagged outersole, elastic tongue/tongue,patterned vamp toe, soft and soft tab heel. With the design of the shoes is expected to provide a shoe design thatis acceptable to the public, has competitiveness and reduces the reliance of shoe design on famous brands

Abstract

The COVID-19 disease, including its prevention and treatment, is becoming a lively conversation in the community. There are many ways to protect yourself from the coronavirus. Apart from doing social distancing, consuming traditional drinks can also be a great way to increase endurance. Jamu has been a part of traditional Indonesian medicine for a long time. Herbal medicine is believed to provide a number of health benefits as well as to treat various diseases. Traditional spices are quite effective in maintaining endurance and are one of the solutions against the increasingly aggressive coronavirus (Covid-19) outbreak. Ginger drink is one of the traditional drinks that is easy to make and has the power to increase endurance to avoid the coronavirus (Covid-19). Ginger contains the bioactive compound gingerol which can fight the respiratory syncytial virus that causes respiratory infections. To make the ginger drink, it is necessary to squeeze ginger from the dregs. So far, the processing is done manually by using a grate and squeezing it by hand. People who grate get tired, especially if they have to grate large amounts of ginger. Based on this, appropriate technological innovations need to be applied to increase production yield and quality of squeezed ginger, namely by making the design of "Automatic Ginger Squeezing Machine" which is quite practical and can be used on a household scale with a capacity of 35 kg/hour and a power of 750 Watts. Ginger that is processed in this machine will be immediately separated from the pulp. The production process will be shorter and more efficient because the ginger juice and pulp are separated automatically with a larger capacity. This machine uses stainless steel to ensure the quality of the processed product and maintain the health of the process. This machine works automatically from the beginning to the end of the ginger pressing process.

Abstract

The rocket motor test stand is the equipment used to test the rocket motor's performance under controlled conditions. This equipment is used to measure the thrust of the Dextrose rocket motor and test the ability of components such as the tube, fuel, nozzle and cap of the rocket itself. Before the Dextrose rocket flight test is carried out, it must go through this test. In this study, the variations in the thrust are 2000, 2250, 2500, 2750, and 3000 N. The rocket motor test stands used Aluminum 6063-T6 which has light density and medium strength. Numerical simulations were carried out with Ansys Workbench software using the finite element method. The results of the static stress analysis show that the greater the thrust, the greater the maximum von Mises stress and deformation. It is inversely related to the safety factor. The greater the thrust, the lower the safety factor of the rocket motor test stand. The results of the fatigue simulation show that the greater the thrust, the lower the prediction of fatigue life and the safety factor. Rocket motor test stand fails to reach a 1 million cycle life at 3000 N thrust.

Abstract

Titanium paduan merupakan material implan yang banyak digunakan untuk implan medis terutama bidang kedokteran gigi ( ortodentik ). Aplikasi implan gigi pada rongga mulut mengalami fluktuasi temperatur sesuai dengan temperatur makanan dan minuman yang masuk kedalam mulut sehingga membuat implan mudah terkorosi. Pada penelitian ini dilakukan pelapisan biokeramik hidroksiapatit pada permukaan Ti6Al4V ELI dengan metode EPD kemudian direndam dengan larutan air ludah buatan selama 6 minggu pada temperatur yang berfluktuasi yaitu 20ºC dan 60ºC. Tujuan dari penelitian ini adalah mengetahui pengaruh temperatur fluktuasi dalam air ludah buatan terhadap laju korosi dari Ti6Al4V ELI yang dilapisi biokeramik dengan metode weight loss ( kehilangan berat ) dan mengetahui pengaruh temperatur fluktuasi dalam air ludah buatan terhadap nilai kekerasan dari Ti6Al4V ELI yang dilapisi biokeramik.Hasilnya laju korosi menurun dari 1,10 mpy menjadi 0,43 mpy dan nilai kekerasan menurun dari 317 HVN menjadi 200 HVN. Hal ini menunjukkan bahwa hidroksiapatit dapat menghambat korosi tetapi tidak dapat mempertahankan sifat mekanis dari implan.

Abstract

One of the components, namely the shaft that is subjected to torsion will experience torsional deformation. The greater the torsional deformation indicates the ability of the engine components is low, and vice versa. The problem that often occurs during torsional testing is that processing the data into a shear stress-strain curve requires a lot of effort. If the specimen used is a solid rod, there will be a fairly steep stress gradient along the cross-section of the specimen making measurements difficult. The objective of this research is to identify and analyze the torsional strength test on low carbon steel by a numerical method using SolidWorks software. The torsion test specimen is low carbon steel with ASTM E-143 standard. This research method begins with a literature study, testing the composition of the test specimen, making and modeling torsion test specimens. After that, torsional testing was carried out which was then carried out with static simulation tests. Then perform a torsional strength analysis using the finite element method using software (SolidWorks). Based on the results of geometry making and modeling of torsion test specimens with ASTM E-143 standard, that the stress distribution that occurs on the surface of the specimen angle area has a value that is not too significant, ranging from 2.879e+09 and 2.973e+09. However, it is necessary to simulate the torsion test of the SolidWorks software with varying mesh sizes and torsion test specimens with different ASTM standards.
