The Importance of Natural ACE2 Inhibitor: Potency of Porang Glucomannan as Anti-SARS-Cov-2

The inhibition of SARS-Cov-2 S binding with hACE2, expressed in most human tissues, may prevent the severity of virus infection. However, commercial ACE2 inhibitor drugs are still limited, while several natural compounds have already been reported to have anti-ACE2 activity. We found the potential of hydrolyzed glucomannan of porang tuber in the inhabitation of binding activity between ACE2 and S1 of SARS-Cov-2.

Waste treatment innovation for infusion bottles using soil solution.

The amount of medical waste, especially infusion bottles, is a problem for environmental pollution. Improper management of infusion bottle waste can have an impact on disease transmission. The medical waste treatment used high technology and high costs will be a financial burden, so simple and effective treatment innovations is needed. This study uses an experimental method of removing bacteria from infusion bottles using a mixture of water and Andoso soil as a solution for washing infusion bottle waste. The soil solution concentration used in washing was 45% with a contact time of 2 minutes. The experiment was carried out with two repetitions. The treatment effect on decreasing the number of bacteria using a multiple linear regression mathematical model. The results showed that the disinfection process of bacterial-contaminated infusion bottles using water required rinsing up to six times, whereas using 45% andosol soil solution only rinsed once. The effectiveness of the disinfection of infusion bottles contaminated with bacteria using soil solution reduces the number of bacteria by 98%.

Adversity Quotient Promotes Teachers' Professional Competence More Strongly Than Emotional Intelligence: Evidence from Indonesia.

Teachers' professional competence has become a popular issue since the COVID-19 pandemic. Therefore, this study investigates teachers' professional competence, in terms of emotional intelligence (EI), adversity quotient (AQ), and organizational citizenship behavior (OCB), when teachers need to deal with abnormal situations, such as the COVID-19 pandemic. Moreover, this study also seeks to explore the relationship of EI and AQ with teachers' professional competence mediated by OCB. The research data were collected through a questionnaire using a Likert scale from 589 participants: elementary school teachers in Indonesia were chosen through accidental sampling. The data analysis used structural equation modeling (SEM), complemented by common method bias, correlational, and descriptive analysis. The result shows that EI, AQ, and OCB have a significant relationship with teachers' professional competence. However, AQ more strongly promotes teachers' OCB and professional competence than EI does. In addition, OCB mediates the relationship between EI and AQ with teachers' professional competence. Accordingly, a new model regarding the relationship of EI and AQ with teachers' professional competence mediated by OCB was confirmed. Therefore, it is suggested that teachers' professional competence can increase through EI, AQ, and OCB. Hence, the new empirical model deserves to be discussed, adapted, and even adopted by practitioners and researchers to develop the professional competence of teachers in the future.

Period use of language terms pandemic COVID-19

A word or phrase (a combination of words) that is used as a name or symbol and which accurately expresses the meaning of a concept, process, state, or characteristic that is unique in a particular field such as science, technology, art and so on. This study aims to describe the characteristic patterns of various linguistic terms during the COVID-19 pandemic. This study uses a qualitative descriptive approach in which this study does not use numbers but in the form of words to describe the results of the study. The technique used in this study is to use observation and data collection techniques. The results showed that there were 36 data on the pattern of the COVID-19 language terms which were analyzed and then classified into 14 data in the form of English, 8 data in the form of synonyms, 3 data in the form of English abbreviations, 4 data in the form of Indonesian abbreviations and 6 data in acronym form. The implication of this research is that many people use foreign terms such as Coronavirus, social distancing, physical distancing, and new normal. Therefore, it is necessary for the role of every citizen, government and media during a pandemic to use the Indonesian language in order to protect the sovereignty of the nation.
