ABSTRACT
Organizational citizenship behavior (OCB) is necessary in overcoming emergency conditions, including learning difficulties such as experienced during and after the Covid-19 pandemic. Therefore, this research explored the visionary leadership effects of teachers' OCB through quality of work-life (QWL) and organizational commitment, and developed a new empirical model of the mediation mechanism. A quantitative approach with a survey method was used in this research, where Likert-scale questionnaires were distributed to 387 social sciences teachers in Indonesia. Using structural equation modeling (SEM) analysis, it was found that visionary leadership, QWL, and organizational commitment have a significant effect on OCB;visionary leadership significantly influences QWL and organizational commitment;and visionary leadership has a significant effect on OCB through QWL and organizational commitment. This evidence promotes a new model regarding the effect of visionary leadership on teachers' OCB mediated by QWL and organizational commitment. It not only confirms several previous studies as the basis for developing this research hypothesis, but is also an antithesis to previous research with contradictory conclusions. With such conditions, the new model provides theoretical and practical contributions which require in-depth and critical discussion before it is adopted or adapted as a model in improving teacher OCB via visionary leadership supported by QWL and organizational commitment. © Authors This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0)
ABSTRACT
Students' misconceptions need special attention, especially in learning physics during the Covid-19 pandemic. This study aims to analyze students' conceptions after learning physics with an online flipped classroom. This study uses a one shoot case study design. The subjects in this study were postgraduate students who took school physics courses in the first semester of the 2020/2021 academic year, State University of Surabaya. The data taken includes learning activities, with observation techniques on the learning process and identification of students' conceptions with a misconception test with the Certainty of Response Index (CRI). Data were analyzed by descriptive analysis. The results of this study indicate that the online flipped classroom learning process makes students actively analyze concepts, find potential misconceptions, and discuss. However, online learning still leaves students with misconceptions. As many as 69.44% of students have understood the concept correctly, but 22.22% of students have misconceptions on certain materials. In a situation where online learning is a must, the application of an online flipped classroom can make students more active, have understanding of concepts, and relatively few students experience misconceptions. © 2022 American Institute of Physics Inc..

ABSTRACT
Since the Covid-19 pandemic, the business organizations' performance has experienced great shocks, including Indonesian banking. This study aimed to investigate Indonesia's banking organizations' performance based on intellectual capital (IC), corporate governance (CG), and enterprise risk management (ERM) with competitive advantage (CA) mediation. It intended to develop a new model that could theoretically contribute to scientific civilization with practical implications for business, particularly the banking industry. Secondary data used was obtained from the Indonesia Stock Exchange (IDX). The sample comprised 185 observations consisting of 37 banks selected through purposive sampling, with the criteria of submitting annual report data for five consecutive years of observation (2016-2020). Data were analyzed using partial least squares structural equation modeling (PLS-SEM). The results showed that IC, CG, and ERM do not directly affect OP. However, IC and CG significantly affect CA, which significantly influences OP. CA indirectly mediates the effect of IC and CG on organizational performance (OP). These results confirmed a new model regarding the effect of IC and CG on OP mediated by CA. Therefore, the bank's OP could improve through IC and CG supported by CA. In line with this, the Indonesian banking sector should simultaneously improve IC, CG, and CA through strategic policies and approaches. The new model developed in this study could be adopted by taking the different fields and samples, other indicators, and using different analytical tools such as Lisrel.

ABSTRACT
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.
ABSTRACT
Tyramine-Fe complex is predicted present in Brotowali (Tinospora crispa) and play a role in its anti-inflammatory activity. Excessive inflammation in COVID-19 patients can be fatal and can even cause death. Anti-inflammatory drugs such as aspirin and ibuprofen inhibits the reaction of prostaglandin formation from COX 2 and arachidonic acid. This study aims to investigate COX 2-tyramine-Fe complex interactions using bioinformatic softwares In this study, docking simulations was performed between COX 2 and tyramine-Fe complex, tyramine, ibuprofen, and aspirin. The results showed that COX 2-tyramine-Fe complex binding site overlapped with the COX 2-ibuprofen binding site while COX 2-tyramine binding site overlapped with the COX 2-Aspirin binding site. COX 2-tyramine-Fe complex's binding energy is smaller than COX 2- tyramine, COX 2- aspirin, COX 2-ibuprofen. These results suggest that the COX 2-tyramine-Fe complex has anti-inflammatory properties so that it can prevent excessive inflammation in COVID-19 patients. © IEOM Society International.
ABSTRACT
Purpose: This study aims to explore how small and medium-sized enterprises (SMEs) in Indonesia display resilience in response to the Covid-19 pandemic. Design/methodology/approach: A qualitative research design was used, which involved semi-structured interviews on five creative industry-based businesses in Yogyakarta, Indonesia. A narrative inquiry approach was used to obtain an in-depth understanding of SMEs’ resilience. The data obtained were analyzed using thematic analysis via MaxQDA 2020. Findings: The Covid-19 pandemic triggered the emergence of both new opportunities and new constraints for SMEs. These, in turn, significantly interrupt their business model. SMEs are found to navigate survival, continuity and growth by drawing from their resourcefulness and firm-level strategies to cope with the new opportunities and constraints. Research limitations/implications: This study was conducted qualitatively based on five SMEs in the creative industry in Indonesia. This limits the ability to compare the findings across different economic sectors. Practical implications: SMEs facing emergent constraints may need to find new ways to recombine existing resources and simultaneously seek to innovate their business model. Business owners and entrepreneurs should adopt a positive mindset such as optimism, perseverance and efficacy, to cope with adversity. Growth-oriented SMEs may make use of a competitive mindset such as flexibility, speed and innovation, to spot and exploit opportunities that emerge from the crisis. Social implications: SMEs’ resilience should be understood not only in terms of economic survival and continuity but, more deeply, about their social contribution to the localities where they operate. Originality/value: This study illustrates the process of how adaptive resilience is adapted and executed by SMEs. It also contributes to entrepreneurial resilience and resourcefulness literature by explaining how entrepreneurs anticipate, respond to and leverage from the crisis. © 2021, Emerald Publishing Limited.
ABSTRACT
BACKGROUND: To date, no recommendations have been published on when and how to start again carrying out elective, non-urgent surgery on COVID-19-negative patients after the epidemic peak has been reached in a given country or region and the pressure on healthcare facilities, healthcare workers and resources has been released by so far that elective surgery procedures can be safely and ethically programmed again. This study aims to investigate whether elective orthopaedic surgery will increase the risk of developing COVID-19. MATERIALS AND METHODS: This was a combined retrospective and prospective studies performed at a national tertiary hospital in Jakarta, Indonesia. Subjects were patients who underwent elective orthopaedic surgeries at our institution from April to May 2020. Those who were previously infected with COVID-19 from polymerase chain reaction (PCR) reverse transcriptase (RT) examination obtained via nasopharynx and oropharynx swab, as well as those who were reluctant to participate were excluded from the study. RESULTS: A total of 35 subjects (mean age 32.89 ± 17.42) were recruited. Fifteen (42.9%) subjects were male, and 20 subjects (57.1%) were female. Mean duration of surgery was 240 min with the longest and shortest duration of 690 and 40 min, respectively. General anaesthesia was performed in the majority of cases in 18 surgeries (51.4%) with local anaesthesia as the least in 2 surgeries (5.7%). Length of stay of our study was 6 days of average. None of the patients developed symptoms suggestive of COVID-19 infection. CONCLUSION: We found that elective orthopaedic surgery may not be associated with increased cases of COVID-19 cases. However, our study was limited by short duration of follow-up. Further studies are required in order to investigate the affect of undergoing elective surgery and the number of COVID-19 cases.
