ABSTRACT
The COVID-19 pandemic has affected economies around the world, including the banking industry, and this depends on various factors. The aim of this study is to understand the influence of COVID-19 independently and through the moderation of bank capital ratios on changes in loans of Association of Southeast Asian Nations 5 (ASEAN-5) banking industry players. The study uses a sample of 86 banking companies listed on the stock markets of Indonesia, Malaysia, the Philippines, Singapore, and Thailand from the first quarter of 2018 to the fourth quarter of 2020 by employing the panel data regression technique. The results showed that COVID-19 had a significant negative effect on changes in bank lending. However, a bank's capital ratio was not found to play a role in moderating the effect of COVID-19 on changes in bank lending. These findings have three main implications: (i) the role of the government in recapitalization and liquidity injection can eliminate differences in behavior between banks with the classification of capital ratios;(ii) there are no signs of zombie lending in ASEAN-5's banking industry;and (iii) regulating incentives to change bank lending behavior in future crises must take into account that bank capital categorization will not be effective. © Michael Abraham Hukom, Arief Wibisono Lubis, 2023.

ABSTRACT
The global COVID-19 pandemic caused by SARS-CoV-2 has been the resulted of massive human deaths since early 2020. The purpose of this study was to determine the potential of mangosteen (Garcinia mangostana L.) as an inhibitor of RBD spike, helicase, Mpro, and RdRp activity of SARS-CoV-2 with an in silico approach. The samples were obtained from PubChem and RCSB PDB. Analysis of the similarity of the drug was carried out with the Swiss ADME on the basis of Lipinski rule of five. Prediction of antivirus probabilities was carried out using PASS Online. Molecular screening was performed using PyRx through molecular docking. Discovery Studio was used for visualization. The bioactive compounds with the highest antiviral potential were indicated with the lowest binding affinity to the targeted proteins RBD spike, helicase, Mpro, and RdRp of SARS-CoV-2. The results indicated that mangiferin has the greatest potential as a potential antiviral. However, more research is required to validate the results of these computational predictions.

ABSTRACT
The aim of this study is to screen the content of bioactive compounds of Moringa oleifera and to identify its potential as an antiviral against COVID 19 through an entry inhibitor mechanism using bioinformatics tools. The sample was obtained from PubChem database. Amino acis sequences were obtained from the NCBI. Protein modeling is made through the SWISSMODEL site. The target proteins for this study were SARS-CoV-2 Mpro and RdRp. The protein-inhibitory interaction of the drug from M. oleifera bioactive compounds to SARS-CoV-2 was predicted by molecular docking with PyRx software.The result shows that M. oleifera was a potential antiviral candidate for SARS-CoV-2 with an entry inhibitor mechanism through a compound, especially quercetin. The RFMS value of both interactions between Mpro and quercetion and RdRp with quercetin were not higher than 1.05. This result still needed further research to prove this prediction.

ABSTRACT
Significant focus has been placed on improving Indoor Air Quality (IAQ) due to the emergence of the large-scale severe acute respiratory syndrome (SARS) virus epidemic in the air conditioning system of buildings. There is also a need for an adequate air ventilation system that balances energy needs with air quality. This led to the discovery of liquid desiccants which have the ability to enhance air quality and lower primary energy usage as an alternative to the standard air dehumidification technology. Therefore, this study was conducted to investigate the dehumidi-fication and regeneration processes in a Fin and tube liquid desiccant system. This involved flowing air horizontally while the ionic liquid flowed through the cooling or heating coil verti-cally downward to create a cross-flow fin and tube configuration. In the testing process, we ob-tained measurements of relative humidity and dry bulb temperature inlet and outlet from ducting by varying the input parameters. Moreover, the differential humidity ratio of the inlet and output process for the dehumidification and regeneration was observed to be essential for the dehu-midifier performance indices. The experimental result showed that the system absorbed a hu-midity ratio of 5.5 g/kg during the dehumidification process and released 10.7 g/kg during regeneration.
ABSTRACT
BACKGROUND: West Java is ranked 4th as the province with the highest number of COVID-19 cases in Indonesia up to December 1, 2020. The COVID-19 pandemic has a major impact on human health, lifestyle changes, and economic life. AIM: The purpose of this study was to analyze the impact of the COVID-19 pandemic on lifestyle changes among the community of West Java. METHODS: The study was conducted in September 2020 using a cross-sectional study design. A total of 2502 people aged ≥12 years living in West Java were involved in this study as a sample, willing to fill out a questionnaire in the form of a Google form that was distributed online through social media (WhatsApp, Facebook, and Instagram). RESULTS: The results showed that the COVID-19 pandemic had an effect on lifestyle changes in the people of West Java. During the COVID-19 pandemic, the people of West Java became more frequent to wash their hands, do regular exercise, sunbathe in the morning, consume more vegetables and fruits, and consume vitamins or supplements to increase endurance (p < 0.05). CONCLUSION: Based on the result, the community should continue to improve the COVID-19 prevention practices in breaking the chain of transmission.
ABSTRACT
Coronavirus Disease of 2019 began in Wuhan in December 2019 and it was declared as a global pandemic by WHO. Until January 2021, it affected all of human activities on earth i.e., experiencing many obstacles from restrictions on activities, closure of tourist attractions to restrictions on face-To-face learning activities in schools or universities. Due to the policy of providing a broad influence on the community with various comments through social media, many twitter users make tweets containing positive and negative comments leading to statements about online learning or daring. The problem is that they contain so many different words, abbreviations, informal language, and symbols, creating difficulties to choose which words or groups of words that can produce positive or negative statements. K-Nearest Neighbors algorithm is used to classify positive and negative tweet data, the results were AUC for class 0: 0.754, 1: 0.635, 2: 0.721 and with a precision classification score of 0.86, recall is 0.85 so that the results of the classification of negative and positive sentences on the online learning tweet data were ROC-AUC of 0. 853 and the accuracy value of 0.885. © 2022 IEEE.

several studies, the benefit of IVIG therapy for COVID-19 remains controversial.6,7 There is limited data that support IVIG's efficacy for TEN-COVID-19 patients and TEN after COVID-19 vaccination. Here, we present two pediatric patients with TEN due to COVID-19 infection and one case with potentially serious adverse reactions to the COVID-19 vaccines that consent was obtained from parental consent.
ABSTRACT
COVID-19 contact tracing is one of preventive solution to slow down the spread of the virus. Some of countries have been implementing manual contact tracing and also digital tracing using smartphone application. The success of the digital tracing implementation requires cooperation from the community and firm leadership from the government as well as medical record reporting from the public health so that the data can be analyzed as soon as possible for the next preventive action required. However, for countries with large population like Indonesia, it is difficult to control the society while the health facilities are quite overwhelmed enough to cope with the number of infected, which has not decreased to date. Proximity-based COVID-19 contact tracing system devices using BLE (Bluetooth Low Energy) technology is focusing on tracing and controlling the spread of virus in local community. For example, the system devices will be implemented in a factory, the devices are put in front pocket of factory employee' shirt or hooked on the shirt. The devices will record the proximity between employees and the data is synchronized using their smartphone or via application to be stored in database. The proximity records will be used once there is an infected employee to obtain information of possibility of other employees are being infected, to avoid massive test and isolation. In addition, the use of this device can be expanded even further. © 2020 IEEE.
ABSTRACT
Time series is a method of forecasting in which it is carried out on the previous data to obtain future data. This study conducted forecasting on the price of gold, in which the process is divided into two patterns. In the first pattern, forecasting used change-based time series with the world economic instability such as the Covid-19 pandemic, and the second pattern is that using time series based on changes with the stability of the world economy. In forecasting, the test level is measuring forecasting accuracy. It can be done by MSE, which is still so easy that optimization is carried out in measuring accuracy by modifying MSE using a false alarm rate in the form of a formula to find the difference. The first pattern process went well and got an accuracy value calculated with the MSE of 0.0538, and the modified MSE measurement technique used the False Alarm Rate of 0.0119. In the second pattern, it also went well and got an MSE value of 0.1508, and the modified MSE measurement technique used a False Alarm Rate of 0.446. Forecasting using change-based time series could affect the amount of accuracy based on the amount of training data so that the more training data, the smaller the accuracy value was obtained, while the less training data, the greater the accuracy value. © 2020 IEEE.
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.
