The analysis showed that the LC50 of Lavender was 151.2 ppm, the LC50 of peppermint was 101.9 ppm, and the LC50 of eucalyptus was 105.7 ppm;all were toxic. © 2023 Author(s).
ABSTRACT
The global COVID-19 pandemic has suppressed the economy and people's welfare, including in Indonesia and Central Java Province, as indicated by the weakening of the national economy by -2.06 percent and locally by -2.65 percent in 2020. Although the economy grew by 3.32 percent in 2021, societal welfare remains lower than in 2019, marked by an increase in unemployment and poverty throughout 2019-2021. Furthermore, the threat of COVID-19 including new variants of the virus continues to weigh on the economy, in 2022 and beyond. This study considered an industrial approach to production, based on inter-industrial linkages and policy simulations with input-output analysis. The objectives of this research are to analyze the impact of the COVID-19 pandemic on the economy of Central Java and to formulate an effective economic recovery policy for industry. The results show that the industries affected by the COVID-19 pandemic in Central Java can promote recovery of overall income in economic industry better than the leading industry and the industries with the highest output multipliers, expressed as a proportional increase in final demand for each industry. Meanwhile, the economic recovery strategy of increasing final demand in industries with high output multipliers results in a faster increase in economic output compared with increasing final demand in the affected industries or leading industries.
ABSTRACT
The COVID-19 pandemic has hit urban areas particularly hard, yet there is a lack of research on the hypothesis that living in more compact cities can provide better support for work and social conditions during the pandemic. This study addresses this gap by examining whether city compactness can mitigate the negative impact of the pandemic on the work and social life of urban residents in Jakarta, Indonesia. The study uses a household phone survey combined with publicly available urban form data. Ordinary Least Squares (OLS) regression, supplemented with a matching technique to address potential selection bias, is employed. The results suggest that living in more compact locations can reduce the disruption to work and social life associated with COVID-19 in urban communities. This positive effect is particularly experienced by males, non-migrants, and individuals from wealthy families.
ABSTRACT
To achieve their investment objectives, each investor has a strategy in place. A high amount of personality traits element influenced (perceived) investment performance. The purpose of this research was to test how the Big Five personality qualities affected (perceived) investment performance. The hypotheses were tested using PLS-SEM. Individual stock investors in Indonesia were studied, and the results revealed that openness and neuroticism personality had a negative impact on (perceived) investment performance. Consciousness, extraversion, and agreeableness, on the other hand, all had a positive effect on (perceived) investment performance. This research shows the importance of personality traits when allocating assets to meet investment objectives and improves behavioral finance theory.

ABSTRACT
BACKGROUND The Indonesian Chronic Disease Management Program (PROLANIS) is a government program that aims to improve the health outcomes of patients with chronic diseases, including hypertension. This preliminary study aimed to evaluate the impacts of the coronavirus disease 2019 (COVID-19) pandemic on the health outcomes of hypertension patients in rural areas who were enrolled in PROLANIS. MATERIAL AND METHODS This study used data from 4 PROLANIS groups in East Java province. The data were collected from participants' 6-month evaluations at 3 time points: before the COVID-19 pandemic in December 2019 (T0), during the COVID-19 pandemic in June 2020 (T1), and in December 2020 (T2). Evaluated parameters were body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low-density lipid (LDL), high-density lipid (HDL), triglyceride (TG), and estimated glomerular filtration rate (eGFR). RESULTS There were 91 patients included in the analyses. Compared to T0, BMI, blood pressure, eGFR, and TC had significantly deteriorated at T1, but LDL, HDL, and TG showed no marked changes. At T2, BMI, DBP, and TC were similar to T0. On the other hand, SBP and eGFR did not improve, while HDL significantly deteriorated. Stratified based on age, worsening of DBP, TC, and LDL at T1 and eGFR at T1 and T2 was only observed in those aged 60 years and older. CONCLUSIONS This preliminary study showed that the health outcomes of hypertension patients in rural areas who were enrolled in PROLANIS were negatively impacted during the COVID-19 pandemic, with the elderly being the most affected.

The present study reported a life experience of a teacher family in Indonesia with a 4-year-old daughter. The observation occurred from March 2020 to July 2021 during the COVID-19 pandemic. This stay-at-home moment became an opportunity to create more parent-kid preschooler bonding and interaction that could impact the developing children language. Indonesian is our family native language (L1);therefore, the exposure started earlier for the kids. However, as parent-kid interaction was enhanced during the pandemic, we boosted our kid English (L2) with a variety of Edu-home activities such as reading aloud, storytelling, role-playing, and watching YouTube-kid. Her language production was documented, and the progress was analyzed. The aim was to generate a more profound understanding of our roles as parents in scaffolding the acceleration of preschoolers' English development, especially in creating meaningful activities. Going through an autoethnography, we reflect on our practice to know how the family members played the role of a language catalyst and which activities were taken more into account.
ABSTRACT
Introduction: IL-12 and IL-10 are cytokines with different mechanisms in the pathogenesis of COVID-19. Differences in IL-12 and IL-10 levels in patients receiving convalescent plasma and non-convalescent plasma recipients need to be known because the total levels of IL-12 and IL-10 also determine the clinical condition of the patient. Materials and Methods: This study used 40 randomly selected blood serum samples with details of 20 samples of COVID-19 patients without convalescent plasma therapy and 20 samples of COVID-19 patients. The COVID-19 patients at the Haji General Hospital in Surabaya provided the patient serum that was utilized. Results: Based on the findings, there were differences in IL-10 levels between the control group and convalescent plasma therapy recipients (P<0.05). On IL-12 levels had no difference between the control and treatment groups (P>0.05). Conclusion: According to statistical estimates, convalescent plasma treatment made a difference to IL-10 but not IL-12 levels in COVID-19 patients. © 2023 UPM Press. All rights reserved.
ABSTRACT
Introduction: The preferred treatment for COVID-19 cases is Convalescent Plasma. In COVID-19 patients, cytokine storms are caused by high levels of cytokines including: Inflammatory cytokines such as (IL-10, IL-12, IL-27, IL-21, TNF-α and IFN-γ, IL-2, and IL-6), are triggered by T cell responses. The goal of this research is to determine Does administration of convalescent plasma affect the TNF-α and IFN-γ cases of COVID-19 sufferers. Materials and methods: The experimental research method uses (a post-test only control group design). The study material in the form of serum from the blood of COVID-19 patients as many as 38 samples selected randomly with details of COVID-19 patients as many as 19 samples were not given convalescent plasma treatment and 19 samples of COVID-19 patients receiving convalescent plasma therapy. Results: This study showed that there was no effect on TNF-α levels before and after convalescent plasma administration (P> 0.05), while IFN-γ levels showed an effect between before and after convalescent plasma administration (P< 0.05). Conclusion: Although in this study there were differences in the results of statistical analysis of TNF-α and IFN-γ levels in convalescent plasma treatment of COVID-19 patients, this study proved to be able to improve the clinical condition of COVID-19 cases. © 2023 UPM Press.

ABSTRACT
SARS-Cov-2 spreads quickly and continues to do so to this day. One way to limit the spread is by limiting people's mobility through transportation. The Provincial Government of Jakarta has implemented the Large-Scale Social Restriction Transitional Phase-1 since June 5th, 2020, to limit people mobility and the odd-even policies August 3rd, 2020, to limit private vehicles. To assess the effectiveness of these policies against the positivity rate of COVID-19 cases in Jakarta, we used data exploration and significant tests (pre-and post-condition). The result shows that the odd-even policy significantly impacts private transportation mobility, mobility in public transportation, and the COVID-19 positivity rate in Jakarta. The relationship between those three parameters is linearly significant. The odd-even policy stimulates people to switch from private to public transportations and increases the positivity rate of COVID-19. The odd-even policy effectively reduces the mobility of private transportation but insignificantly reduces the positivity rate of COVID-19 in Jakarta. The results can be used as insights for policy decision-makers to manage the COVID-19 pandemic. © 2023 Author(s).
ABSTRACT
Background: One of the efforts to control SARS-CoV-2 infection in health workers is vaccination. In this study, the levels of SARS-CoV-2 neutralizing antibody (nAb) in health workers were measured with Ichroma and iFlash. Method(s): This study applied an observational analytic design with a prospective cohort and was conducted at Dr. Soetomo Regional Public Hospital, Surabaya, from January to November 2021. The population of this study included a total of 75 health workers after taking the second dose of the SARS-CoV-2 (Sinovac) vaccine. The Covid-19 NAb levels of the population were tested with Ichroma and iFlash on day 0 before vaccination, as well as days 14 and 28, and months 3 and 6 after vaccination. Result(s): The Friedman test indicated a significant difference in NAb levels according to the iFlash test on day 14, day 28, month 3, and month 6 compared to those before vaccination (p < 0.05). The Wilcoxon test revealed a significant difference in NAb levels on day 14, day 28, month 3, and month 6. The results of the Cochran test showed a significant difference in the positivity of NAb according to the Ichroma test on day 14, day 28, month 3, and month 6 compared to those before vaccination (p < 0.05). McNemar's test demonstrated that the COI at month 3 was not significantly different from that before vaccination;The COI at month 6 was not significantly different from those at days 14 and 28. The results of the Pearson correlation test and Bland-Altman plot indicated a moderate correlation between Ichroma and iFlash (r = 0.592, p = 0.002). Conclusion(s): Neutralizing antibodies for Covid-19 were formed after day 14 and started to increase on day 28 and started to decrease in months 3 and 6. The levels of NAb for Covid-19 were measured with Ichroma and iFlash in roughly the same pattern and had a moderate positive correlation.Copyright © 2023 Phcogj.Com.
ABSTRACT
Studies evaluating the levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) anti-spike protein receptor-binding domain (S-RBD) immunoglobulin G (IgG) antibodies in vaccinated healthcare workers in Indonesia are limited. Objectives: Evaluating time-dependent levels of anti-IgG S-RBD antibodies and monitoring the response of healthcare workers in a tertiary hospital in Indonesia after vaccination. Materials and methods: This prospective cohort observational study was conducted from January to December 2021. A total of 50 healthcare workers participated in the study. Blood samples were collected at five time points. Antibody levels were measured using a CL 1000i analyzer (Mindray Bio-Medical Electronics Co., Ltd., Shenzhen, China). Antibody levels between groups were analyzed using the Wilcoxon signed-rank test with P less than 0.05. Results: The median levels of SARS-CoV-2 anti-S-RBD IgG antibody on days 14, 28, 90, and 180 were significantly higher than the levels on day 0 (P<0.001). After the second dose, peak levels were observed on day 14; the levels decreased gradually after day 28. Despite receiving two doses of the vaccine, 10 out of 50 participants (20%) were infected with COVID-19 (coronavirus disease 2019). However, symptoms were mild, and antibody levels were significantly higher than in noninfected participants (P<0.001). Conclusion: SARS-CoV-2 anti-S-RBD IgG antibody levels increased significantly until day 14 after the second dose; the levels decreased gradually after day 28. Ten participants (20%) were infected with SARS-CoV-2, with mild symptoms.
ABSTRACT
The authors reported two patients with a history of asymptomatic mild mitral valve prolapse, a male in his late 40s (Case 1, vaccinated) and a female in her late 20s (Case 2, unvaccinated), who developed worsening (severe) mitral prolapse and New York Heart Association symptoms class III-IV after exposure to coronavirus disease 2019 with evidence of myocarditis on MRI. Both patients received similar 6-month of heart failure therapy; however, the outcomes did not affect the severity of their symptoms or mitral regurgitation. Subsequently, both patients underwent mitral valve surgery.
ABSTRACT
Background: COVID-19 cases surge, it has a crucial impact on healthcare systems, with rapidly increasing demand for healthcare resources in hospitals and intensive care units (ICUs) in Indonesia and worldwide. It is necessary to quantify the extent to which the effects of the COVID-19 pandemic on the hospital admissions, and clinical and financial outcomes of patients with non-COVID-19 respiratory symptoms. Objective: To determine whether the COVID-19 pandemic changed the hospitalisation of child and adult patients with non-COVID-19 respiratory conditions and whether these changes affected the patient's disease condition, clinical outcomes, and hospital finances. Methods: A retrospective cohort study was conducted from May 1, 2018 (before the COVID-19 pandemic) until December 31, 2021. Total sampling was done to compare hospital admission of patients with non-COVID-19 respiratory symptoms before versus during the COVID-19 pandemic. The results were analyzed using SPSS 26.0 and SmartPLS.v.3.2.9. Results: There was a reduction in hospitalisations for respiratory disorders unrelated to COVID-19 during the pandemic by 55.3% in children and 47.8% in adult patients. During the pandemic, the average hospital revenue per patient of child and adult patients increased significantly, but the profit per patient decreased. Pathway analysis showed that in children, the COVID-19 Pandemic changed disease severity and complexity (ß = 0.132, P < 0.001), as well as clinical outcomes (ß = 0.029, P < 0.05). In adults, the COVID-19 pandemic improves disease severity and complexity (ß = -0.020, P < 0.001), as well as clinical outcomes (ß = -0.013, P < 0.001). COVID-19 pandemic increases care charges (in children with ß = 0.135, P < 0.001; and in the adult patients with ß = 0.110, P < 0.001), worsens hospital financial outcomes relating to child (ß = -0.093, P < 0.001) and adult patient (ß = -0.073, P < 0.001). In adult patients, seasonal variations moderate the impact of the COVID-19 pandemic on improving disease conditions (ß = -0.032, P=<0.001). The child structural model effectively predicted clinical outcomes (Q2 = 0.215) and financial outcomes (Q2 = 0.462). The adult structural model effectively predicted clinical outcomes (Q2 = 0.06) and financial outcomes (Q2 = 0.472). Conclusion: The conclusions are that the number of non-COVID respiratory patients decreased during the COVID-19 pandemic (47.8% in adult patients, 55.3% in child patients). Disease severity and complexity increased in child patients but decreased in adult patient. Costs of care and insurance payments increased. Since the insurance payments did not increase as much as the cost of care, hospital profit decreased.

There was a significant difference in the expression of IL-17 in the COVID-19 group and the non-COVID-19 group with p-value = 0.001 (p < 0.05). There was a significant correlation between the expressions of IL-6 and IL-17 in the COVID-19 group, with the Spearman coefficient value (rs) of 0.548 with p = 0.034 (p < 0.05). Conclusion: There are differences in the expression of IL-6 and IL-17 between COVID-19 and non-COVID-19 lung tissue. There is a significant correlation between the expressions of IL-6 and IL-17 in post-mortem lung tissue of COVID-19 patients.
ABSTRACT
The use of private vehicles during the Covid-19 pandemic has increased because private vehicles, especially cars, are considered as the safest mode of transportation to maintain distance and prevent transmission of the Covid-19 virus. Based on data from two different Indonesian secondary car market place, a comparison of a price sample of Car X in the city of Surabaya with the specifications for the 2015 to 2018 car years with car milage under 1000 kilometers, the used cars have a variety of prices hence a used car price prediction system is needed so that people can find out the average price of used cars sold in the market. In this study the author will use the Random Forest Regressor as a machine learning algorithm to predict the price of a used car with a dataset from the AtapData website. The reason for choosing the Random Forest Regressor is because the algorithm has the power to handle large amounts of data with high dimensions with categorical and numerical data types. The evaluation method used in this study is the Root Mean Absolute Error which produces a value of 0.55612 for validation data and 0.56638 for testing data, while the evaluation proceed with Mean Absolute Error produces a value of 0.45208 for validation data and 0.47576 for testing data. © 2022 IEEE.
ABSTRACT
Problem-solving skills are part of Critical Thinking which focuses on the student's abilities to face the 21st century. Recently, one technique to foster and improve problem-solving skills is by learning through Computational Thinking. Many previous studies have described that Computational Thinking is a problem-solving technique adopted from Computer Sciences. However, Computational Thinking learning had been carried out in class or asynchronous. The COVID-19 situation raises the challenges of how Computational Thinking can be taught online. Therefore, this study aims to develop an instructional design in online-based computational thinking learning. The development of this study employs the ADDIE method. The final step of the development stage was carried out through a small-scale online class experiment.
