ABSTRACT
Efforts to resolve the COVID-19 pandemic are a common goal set out in the Sustainable Development Goals (SDGs). However, the rate of spread of COVID-19 in several countries is still high. To control the spread ofthe COVID-19 pandemic, various countries have implemented several strategic measures. In Indonesia, the government through the COVID-19 Handling Task Force has classified areas based on the level of risk ofthe spread of COVID-19. East Java as one of the major provinces is a province dominated by regencies and cities with a moderate level of risk of spreading COVID-19 (orange zone) and low (yellow zone) in Indonesia. Controlling the rate of spread ofthe COVID-19 pandemic is relatively more controlled in the yellow zone area. For this reason, research was carried out to create statistical modeling related to the level of risk of COVID-19 in each regency and city in East Java which was influenced by various indicators. In this study, we used factors affecting level of risk of COVID-19 namely the number of confirmed positive cases of COVID-19, the recovery rate, and the fatality rate. The method used in the analysis is spatial approach based on the Geographically Weighted Logistic Regression (GWLR) method. The results show that the percentages of regency and cities in East Java that the recovery rate and the number of COVID-19 positive confirmations factors significantly affect on the level of risk of COVID-19 are 78.95% and 18.42 %, respectively. The GWLR model has better classification accuracy of 84.21% than that of global logistic regression model of 76.30%. The opportunity for an area to have a low level of risk of spreading COVID-19 will increase as the recovery rate increases. Therefore, the government can encourage each region to increase the recovery rate to reduce the spread of COVID-19. © 2022 American Institute of Physics Inc.. All rights reserved.
ABSTRACT
The COVID-19 outbreak affected the world badly in this 21st century leading to the closure of all types of anthropogenic activities. It is declared that there was an environmental betterment in names of water quality and air quality during the COVID-19 period. In this study, we analyzed the improvement in water quality by evaluating the suspended particulate matter (SPM) using the remote sensing technique in a tropical South Sumatra wetland i.e., Musi River in Southern Sumatra, Indonesia. The SPM values were estimated from Landsat 8 images Level-2 product. A quantitative and spatial analyses of before (20th May 2019), during (22nd May 2020), and after COVID-19 (28th May 2022) periods were also calculated. Results revealed that the mean SPM values during COVID-19 period (4.56 mg/L) were lower than that before COVID-19 period (8.33 mg/L). Surprisingly, SPM showed an increase of 54% in SPM values after COVID-19 period, compared with during COVID-19 period. The role of human activities including industrial and domestic wastes during the restriction period was the main reason for alteration of pollution loads in the river. Outputs of this study can be used to arrange policies for the sustainable management of aquatic environments and water resources. © 2023 the Author(s), licensee AIMS Press.
ABSTRACT
The pandemic has transformed various aspects of everyday life. Since it first spread in 2020 until this day, the world has drastically reduced face-To-face interaction, resulting in almost all daily activities have been adapted to the virtual world. Social media, the bridge that connects people at this time when social distancing is imposed, records public issues and opinions in these difficult times. Entering the post-pandemic era, social media plays an important role in recording the world's journey to deal with the impact of COVID-19. This study examines the dissemination of information in one of the social media that is widely used by the world's population, Twitter. With the quantitative method, the distribution of information on Twitter related to what issues are being discussed post-pandemic is analyzed. The trend of information in this application shows the focus mainly fell on various social issues that affect many people, especially regarding economic recovery. The results of this study can be used as a source of information or a reference source, and can also be used as data in predicting various kinds of post-pandemic activities. © 2022 EDP Sciences.

ABSTRACT
The case of Coronavirus Disease 2019 (COVID-19) is growing rapidly worldwide. More than 6 million people in Indonesia were confirmed to be infected as of March 2022. This disease caused an increase in the demand of respiratory assistance and intensive care services back in 2021. Unfortunately, the report about COVID-19 case in Intensive Care Unit (ICU) of Indonesia is very scarce although it is very crucial to evaluate the treatment approach and the prognosis of the patients. This study aimed to determine the characteristics, therapy, and outcomes of critically ill COVID-19 patients treated in the ICU. This was a multicentre retrospective study conducted in 12 hospitals in Indonesia from April 2020 to March 2021. All data regarding the characteristics, therapy, and outcomes of COVID-19 patients admitted to ICU were recorded and analysed. 1,502 patients were included in this study. Inpatient mortality occurred in 44.67% patients. The highest morbidity is attributed to stroke (83.4%). We found a significantly longer duration of mechanical ventilation use in non-survivors group (5.57 vs. 1.74 hours). Furthermore, the results of this study showed a significant difference in all type of treatment (excluding antifungal) between two groups. The mortality of COVID-19 patients in ICU is considerably high. Hypothyroidism and DMIІ patients showed a high serum asprosin, which linked with poor glycemic and lipid management. It is a biomarker for diabetes and thyroid issues. © 2023 by SPC (Sami Publishing Company)
ABSTRACT
The Covid 19 pandemic, which is still ongoing, necessitates that we be able to respond to new behaviors by introducing health precautions such as preserving cleanliness and keeping distance by avoiding crowds in order to limit the spread of Covid 19. This undoubtedly has an effect on people's lifestyles, particularly purchasing patterns. Some people also opt to shop only once a week in order to minimize their encounters with a large number of people. As a result, they choose frozen foods that can be processed for an extended period of time and prefer to buy online. When conducting online transactions, it is common to notice the risks that can arise. The aim of this analysis is to evaluate the impact of confidence, convenience, and risk perception on online purchases of frozen food items. This study employs quantitative approaches as well as survey analysis. The study data where gathered by providing questionnaires to 100 frozen food customers. SPSS 25.0 was used to process the obtained data. According to the findings of partial data processing, ease and risk expectations influence the decision to buy frozen food items online. However, confidence has no bearing on the decision to buy frozen food items online. Meanwhile, the effects of simultaneous data processing suggest that trust, convenience and risk perception have an impact on the decision to buy frozen food online.
ABSTRACT
Covid-19 pandemic has changed the world of education where the learning process is done remotely by using an online learning system (online) which is done at home. The need for a device learning is designed to be able to support the distance learning process and achieve 21st century competence, which is directly involved in the learning process using internet facilities. This study aims to develop online learning tools using Inquiry Learning model for physics subjects on equilibrium of rigid bodies. The syntax of the Inquiry Learning model 1) orientation to the problem, 2) making a hypothesis, 3) collecting data, 4) processing the results of the data, and 5) formulating conclusions. The researcher used research and development method (Research & Development), using the ADDIE models (Analysis, Design, Development, Implementation,Evaluation). The validation results of the three experts and the overall average teacher showed a percentage of 81.89%, it can be categorized in a very good category. This online learning tool can be declared very good or feasible to use in physics lessons on rigid equilibrium material. So, the development of online learning tools using inquiry learning model on rigid equilibrium material is effective and suitable for the physics learning process of class XI senior high school.
