Abstract

Ice crystal is a daily needs for consumables, so that it needs an inovation that serves as asupport to sover the needs of ice crystal. For the performance of tools needed automation made tofacilitate the performance of this ice crystal machine, with the main drive of the DC motor made forthe ups and downs of the plate as a mold for this ice crystal, then in the automation writer usesArduino as a micro-controller that will capture the DS18B20 sensor. with a DS18B20 sensor that cancapture sensors below -55 ? so that when the ice crystal is frozen the sensor will read and move theDC stepper motor that makes the automatic plate down and the ice crystal attached to the evaporatorwill be released with a reverse process on the system. Ice crystal will fall automatically and prepare atray as a base to hold the ice.

Abstract

Banyak pengaplikasian Axial Fan di bidang industri. Terutama untuk sistem ventilasi dan cooler suatu sistemyang lainnya. Untuk mendesain sebuah blade axial fan perlu designer untuk memperhatikan studi airfoil.Namun, tidak banyak tulisan yang membahas dalam tentang airfoil terutama pada kebisingan dan getaran yangdapat berdampak terhadap performa axial fan menggunakan metode komputasi atau dengan bantuan software.Penelitian ini melakukan analisa axial fan menggunakan metode komputasi atau dengan bantuan softwareANSYS CFX untuk mendapatkan nilai efesiensi, volume flowrate, rpm, dan tekanan. Dengan mendapatkan nilaiefesiensi, volume flowrate, rpm, dan tekanan dari setting angle dan airfoil yang tepat maka dapat dipilih dandilakukan untuk fabrikasi. Desain airfoil dipilih menggunakan bantuan software Designfoil R6.46 dan situs resmidari NACA (National Advisory Comitee for aeronautics). Desain axial fan di bentuk menggunakan softwareANSYS Geometry. Setelah mendapatkan semua desain 3D axial fan, desain tersebut di import ke dalam softwareANSYS CFX untuk mendapatkan data efesiensi, air flow rate, kebisingan, dan getaran

Abstract

Transmission of COVID-19 is still increasing in the world, such as in China andIndonesia. One of the reasons for the increasing number of positive cases of COVID-19 isthe occurrence of transmission from industrial clusters, the implementation of a minimumsocial distancing of 1 to 2 meters between workers is difficult to do. This is due to limitationsin layout, area, and industrial work systems. Thus, a system is needed to protect industrialworkers from potential exposure to COVID-19. One technology that has high potential to beapplied is air curtain. From these problems, this research will carry out an analysis of theoptimum push-pull discharge and air velocity, and the regime map for downward push-pullair curtain, the method used to carry out the analysis is Computional Fluid Dynamics (CFD)where the stages of the CFD process are preprocessing, processing, postprocessing. Thesoftware used to complete this final project is SALOME for the preprocessing,, OpenFOAMfor the processing, and for the postprocessing stage using ParaView. From the simulationresults that have been carried out, the results show that at a nozzle blow speed of 6,24 m/s,with a suction nozzle speed of 37,44 m/s, these are the optimum blow speed and suction nozzlevalues and are able to withstand droplet dispersion.
