Abstract

This study aims to examine the influence of corporate governance factors on firm value and earnings quality as mediating variables. Research Methodology Using Purposive Sampling techniques, so as to obtain a data of 102. The analysis technique used was to use multiple regression and path analysis. Indicator of corporate governance has effect on firm value are managerial ownership and audit committee. Indicator of corporate governance has effect on earnings quality are Institutional ownership and audit committee. The earnings quality has no significant effect on the value of the company and has not been able to mediate the influence of managerial ownership, institutional ownership and committee on the value of the company. The corporate governance indicator is used 3 while there are other indicators such as the proportion of the independent commissioners board and the proportion of the board of directors.

Abstract

When hospitalized, children have to be left behind by their loved ones, family and friends that it causes anxiety to the children. In addition to anxiety caused by separation, children can also experience anxiety due to losing control of themselves. The implementation of Play Therapy is part of child care and one of the effective interventions for children. The purpose of the study is to determine the effect of the application of Play Therapy on reducing anxiety in pre-school age children at RSUD Haji Provinsi Sulawesi Selatan. The research method used was Quasy experiment with a pre-test and post-test control group approach. The subjects in this study were pre-schoolers with a total sample of 40 people consisting of 20 people in the treatment group and 20 people in the control group with the determination of the sample using consecutive sampling. The instrument used to measure the level of anxiety was the Hamilton Anxiety Rating Scale (HARS), while the intervention was in the form of Play Therapy, especially drawing and coloring games. The results showed that the Wilcoxon Signed Rank Test statistical test in the treatment group obtains a significant value of p = 0.000, smaller than ? = 0.05, which means that there are differences in anxiety levels from the results of the pre-test and post-test. Meanwhile, in the control group, a significant value of p = 0.480 is obtained, which is greater than ?= 0.05, meaning that there is no difference in the level of anxiety from the results of the pre-test and post-test.

Abstract

One of the fastest growing sectors is wireless technology, which is evolving in all areas of mobile and wireless communications. Wireless technology has increased greatly in the last decade. 7.5 Generation (G) represents the history of wireless technology today. With 6G and 7G, data transmission rates will be higher over Future Generation wireless technology. With new technologies emerging in all fields of mobile and wireless communications, wireless technology continues to emerge as one of the hottest sectors with a high rate of development. Currently, 5G mobile communications systems are just getting started. Our current infrastructure supports a number of technologies, including voice over IP (VoIP), broadband data access over wireless, and more. This paper discusses several generations of wireless technologies from 0G to 7G. Wireless technology is important and beneficial to society. In this paper, we compare all of the generations and explain how each generation uses technology in its execution, application, and usage.

Abstract

The use of freezer machines has now become a necessity for the wider community, because it is very helpful for humans in everyday life. The cooling load given greatly affects the performance of the freezer, both in terms of electrical energy consumption and the ability to increase system usage time. The greater the cooling load will increase the use of electrical energy during operation. This is very worrying in the future where the issue of depleting fossil energy sources which is currently a priority for producing electrical energy is increasing and filling the media. In recent years, solar energy has been rumored to be the answer to this problem. Where heat energy from the sun is used to move protons and electrons in a solar panel media to produce electrical energy that can be used for the needs of many people. This has become the attraction of researchers to make an innovation in the use of solar energy in a freezer system. Judging from the research roadmap related to solar energy and the vapor compression system in the freezer that was launched in the last few years, not many innovations have been carried out in the use of energy sources. The cooling load to be used will be adjusted to the capacity of the energy source used, which is 410 WP. With the capacity of the freezer that is used with a power of 1/4 PK which will increase its ability/ efficiency to be used and replace the paid electric energy freezer. This is expected to be useful for the public and contribute knowledge and help realize the university roadmap in the future.

For many centuries traditional markets have become the economic strength of Indonesian society where trading business actors gather to carry out buying and selling transactions. Along with the development of the era, the advancement of information technology is developing very rapidly and changing many patterns of people live from various aspects of life as well as trade. In conventional trade, relying on traditional markets is considered inefficient considering the too long distribution channels of goods and the emergence of additional costs in trade, which causes a high cost economy. The shift of traditional markets to digital markets is an inevitable demand. This study discusses Digital Transformation in traditional markets and how the process should take place to provide some solutions to existing problems. The method used in this research is library research. The research locations are traditional Indonesian markets. Sources of data in this study were collected by collecting methods through literature, scientific publications, information from the internet. The data is induced and concludes the arguments that are made. The findings of this study are: The digital transformation of traditional markets to digital markets has not been fully carried out in Indonesia. Solution: Traditional market players are starting to open up to the online market. It is time for the government to build online infrastructure to move traditional markets to digital markets, although not completely so that marketing efficiency and convenience can increase overall welfare.
