The Effect of Female College Students' Perception of VR on the Expectation of VR-using Beauty Education

In the era of the 4th industrial revolution, various 4th industrial technologies are being used in the beauty industry. Therefore, education courses using the 4th industrial technology are needed for beauty education as well. Therefore, this study tried to apply to beauty education by empirically examining the perception of VR and expectations for VR applied beauty education among beauty major learners. A total of 106 beauty-related learners from 1st to 4th grade participated in the study. As a result of analyzing the perception of VR, there was a statistically significant difference according to the grades (p<.01), and the higher the grade, the higher the perception of VR. In addition, the perception of VR was found to have a statistically significant (p<.001) positive (+) correlation with educational, immersion, interest, and deviance by sub-factors of VR applied beauty education expectations. It was found that the higher the awareness, the higher the educational, immersive, interesting, and deviant factors of VR applied beauty education expectations. These results confirm the learners' expectations for the operation of beauty courses using VR and the necessity of developing VR-using beauty courses in the beauty education environment. Therefore, in beauty education, it is necessary to quickly realize the development and operation of beauty education courses using VR in line with the 4th industrial revolution era, thereby reviving the expectations of learners. For follow-up research, it is necessary to develop a VR-using beauty course or study after the course is operated.

Industrial Revolution: A History of Industrial Revolution and Its Influence in Manufacturing Companies

Before the existence of industrial technology, people in doing their job using their power. People were able to produce goods and sell services with their power. These activities are ineffective because they are constrained and take a long time, so the discovery of industrial technology is today. This study aims to determine the meaning of the industrial revolution, the history and development of the industrial revolution 1.0 to 4.0, the relationship between the industrial revolution and Indonesian history, and the influence of the industrial revolution in Indonesian manufacturing. Indonesian people do not understand what revolution means and how it relates to Indonesian history, where the current and former situation is very different because of a revolution, especially the industrial revolution. The discovery of industrial technology or industrial revolution makes human development become advanced and rapidly growing. In this study, the author uses a method in the form of a Literature Review (LR) or a literature review and data obtained from several articles that have been published and registered online. Technology is believed by many people to make their work easier and takes a short time. The development of technology became necessary because of the emergence of the industrial revolution 4.0 that changed human life. This article tries to review the understanding of the industrial revolution, its development history, and its influence on Indonesian manufacturing companies. The limitation or weakness of this research lies in the research process, namely the author's weakness in collecting the reference sources used.

A discussion of S.M. Krylov’s book «Neocybernetics» (2008)

A comparative analysis of the “general formal technology (GFT)” by S. M. Krylov is carried out in the context of the published book of the authors “General Theory of Technologies and Microelectronics” (2020) and on the basis of his work of 2008. Despite the abstractness of the algebraic-algorithmic approach, Krylov offers a number of specific constructions that are in demand during the fourth industrial revolution and for the future development of industrial technology in nanoelectronics and biotechnology. Industrial technology is considered as a complex object of management, i.e., it is the object of study of the new discipline «neocybernetics». Although the foundations of this approach were laid in 1930s–1960s within the framework of logical and mathematical research, its expansion is inevitable when using self-organization processes to obtain functional supramolecular structures in technological processes of nanoelectronics (for example, DNA origami engineering). The issues of complexity quantification for a product itself (structure) and its manufacturing technology, or, according to Krylov, the complexity of technological automata, have become even more relevant than before. The theoretical issues of self-organization, the development of artificial life, and the creation of self-replicating technical systems also seem promising for solution. In our opinion, Krylov’s formal technology is an important “block” in the advancement of general theory of technologies (GTT) useful for describing the technology at the levels: operation, route, and process. We would like to encourage a wide range of readers to study the book and form a steady interest in general technological issues. The value of GTT and GFT extends beyond the sphere of technology and, in a narrow sense, factory production, but also into the area of «fine» regulation of physiology in biological objects and pharmacy, as well as into the problem field of cognitive sciences, psychology, and education. when the focus is on the personality structure and heterogeneous constructs «floating in the sea of the unconscious». Both S.M. Krylov and we demonstrate that the issues of industrial technology cannot be considered without abstract formalization and without reference to philosophy.

Measurement of Outside Thread Pitch Distance Results of TONGTAI TCS 1500[M] CNC Lath Using Profile Projector

Research has been carried out on the Measurement of the Outer Thread Pitch Distance from the Tongtai Tcs 1500[M] Cnc Lathe Using a Projector Profile. The use of a screw system to unite two components, is almost always found in all industrial technology results from the form of industrial technology with a low level of accuracy (rough) to a very high level of precision (precision). Therefore the screw system has become one of the important factors in industrial progress in all types of production. The higher the level of a component made means the higher the level of accuracy of the thread system. In this study, calculations were carried out to determine the level of precision of a thread made through the machining process using a TONGTAI TCS 1500 [M] CNC lathe. The precision measurement was carried out by measuring using a dimension measuring instrument, namely Profile Projector type HST-CPJ-3000/3000Z. To find out the average value and the value of the screw deviation, a research and measurement process was carried out with several product samples or test objects (sample A, sample B, sample C) where each sample was the same size, namely M15 × 50 P 1.5. The first measurements were made on the major and minor diameters. Because this measurement is more focused on the level of precision of the thread pitch distance, the second measurement is carried out by measuring the dimensions of the distance between the pitches as much as N = 10. From the 10 measuring points of the thread pitch distance, different average values and deviation values will be produced although in the same size.. The purpose of this study was to determine the level of pressure of a thread made through a machining process which in this study used a CNC TONGTAI TCS 1500 [M] lathe. it is known that the overall average value of the three samples is with a major diameter = 14,949 mm, a minor diameter = 13,219 mm, and a thread pitch distance = 1.5309 mm.

Canna (Canna edulis Kerr.) is a type of tuber plant with a fairly high starch content to be used as food. The use of canna is generally processed first into flour. The initial process of flouring canna is done in two ways; the canna plants are sliced and grated. The Department of Agricultural and Biosystem Engineering, Faculty of Agricultural Industrial Technology, University of Padjadjaran, designed the TEP-1902 Canna Slicing and Shredding Machine (MPPG). However, the performance of this machine was not yet known, so testing was needed to determine its performance. The research method used was an experimental method that was analyzed descriptively by measuring, observing, calculating, analyzing, testing, and evaluating the TEP-1902 Canna Slicing and Shredding Machine (MPPG). The results of the performance test of this machine showed that the machine's performance was good, with the following parameters: the actual capacity of the slicing unit and grating unit was 40.95 kg/hour and 182.98 kg/hour, respectively, efficiency was 92.61% slicing and 97.60% grater, the yields were 98.75% slicing and 96.50% grating, respectively, the average thickness of the slices was 2.13 mm, and the uniformity of slice thickness was 65.51%.

Development of technology for the production of a lightweight observation and protective container (LOOK) made of nanostructured ultra-strength steels

The article contains results of research and analyses concerning application of nanostructured bainitic steel in the form of plates for manufacturing of armour components. The presented results of examination of microstructure and properties include a wide range of laboratory experiments and industrial tests, which resulted in the achievement of the assumed functional properties. In the period of 2017-2021, a scientific and industrial consortium consisting of Łukasiewicz – Institute of Ferrous Metallurgy (leader); WITPiS, Tarnów Mechanical Works, Alchemia and Heatmasters Poland carried out a project funded by the POIR 04.01.04 programme aimed to develop the design and to manufacture an observation and protective container with a specified resistance to penetration by armour-piercing projectiles and with a lower mass of steel armouring in relation to that currently produced. The aim of the project was achieved by using armour plates made of nanostructured bainitic steel (nanobainitic), which are characterised by high resistance to high-energy impact concentrated in a small area. The technological tests carried out in the project mainly concerned the development of a new container and industrial technology of armour plates production and their application in the armour of this container. Based on the results of investigation of the semi-industrial scale material, the optimum chemical composition for industrial scale melting and casting was determined. An industrial technology for the production of plates of nano-structured bainitic steel was developed, which includes the following processes: smelting and casting, preliminary heat treatment and ingot hot processing, as well as hot rolling, final heat treatment, and surface treatment. A test batch of the material in the form of 1500×2470 mm armoured plates was fabricated under industrial conditions. The final result of the project is a container armoured with bainitic nanostructured steel plates with implementation documentation and a technology for producing armoured plates from this steel under the technical and technological conditions of domestic steel manufacturers.
