Technology Innovation of Ginger Spring Machine as a Traditional Jamu for Coronavirus Prevention: Inovasi Teknologi Mesin Otomatis Pemeras Jahe Sebagai Jamu Tradisional Untuk Pencegahan Virus Corona
No full textThe 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

Effect Of Water Content On Characteristics Fuel From The Municipal Solid Waste Through The Pyrolysis Process: Effect Of Water Content On Characteristics Fuel From The Municipal Solid Waste Through The Pyrolysis Process
No full textThe increase in the population of Indonesia is proportional to the increase in the amount of waste produced. Municipal solid waste (MSW) especially organic waste, can be used as solid fuel by means of the torefaction process. Torefaction is a thermo-chemical heat treatment method for biomass conversion that takes place at a temperature of 200oC to 300oC under conditions of atmospheric pressure and in the absence of oxygen. The purpose of this study was to determine the effect of moisture content on calorific, proximate and ultimate values of torefaction samples using municipal solid waste. Setting the water content in the mixed sample (30% rice + 70% wood) with variations in moisture content of 30%, 40%, and 50%; and rice and wood samples with variations in moisture content of 40% and 50%. The torefaction was carried out at a temperature of 300oC for one hour and inert gas N2. Torefaction products have been tested contain of the calorific value, proximate testing, and ultimate testing. The results obtained were the best calorific value in the rice sample, the moisture content of 40% was 6351.1 cal / g or equivalent to sub-bituminous coal. The proximate and ultimate results of the best heating value are rice samples with 40% moisture content, fixed carbon 62.95%, volatile matter 27.85%, moisture 7.06%, ash 2.14%, carbon 71.85%, hydrogen. 2.80%, nitrogen 3.17%, and sulfur 0.05%. The calorific value calculation method that is almost close to the test results is the Dulong method, with an average error percentage of 1.63%

No full textTitanium 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

Analysis Numerical Of Torsion Strength Of Low Carbon Steel Using Software (Solidworks): Analisis Numerik Kekuatan Puntir Baja Karbon Rendah Menggunakan Software (Solidworks)
No full textOne 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
