PARAMETER ESTIMATION OF COVID-19 COMPARTMENT MODEL IN INDONESIA USING PARTICLE SWARM OPTIMIZATION

Background: The government established a vaccination program to deal with highly reactive COVID-19 cases in Indonesia. In obtaining accurate predictions of the dynamics of the compartment model of COVID-19 spread, a good parameter estimation technique was required.. Purpose: This research aims to apply Particle Swarm Optimization as a parameter estimation method to obtain parameters value from the Susceptible-Vaccinated-Infected-Recovered compartment model of COVID-19 cases. Methods: This research was conducted in April-May 2020 in Indonesia with exploratory design research. The researchers used the data on COVID-19 cases in Indonesia, which was accessed at covid19.go.id. The data set contained the number of reactive cases, vaccinated cases, and recovered cases. The data set was used to estimate the parameters of the COVID-19 compartment model. The results were shown by numerical simulations that apply to the Matlab program. Results: Research shows that the parameters estimated using Particle Swarm Optimization have a fairly good value because the mean square error is relatively small compared to the data size used. Reactive cases of COVID-19 have decreased until August 21, 2021. Next, reactive cases of COVID-19 will increase until the end of 2021. It is because the virus infection rate of the vaccinated population is positive . If occurs before the stationary point, then the reactive cases of COVID-19 will decrease mathematically. Conclusion: Particle Swarm Optimization methods can estimate parameters well based on mean square error and the graphs that can describe the behavior of COVID-19 cases in the future.

Survival Analysis Of Health Rate Of Covid-19 Patients Using Kaplan-Meier Method At Islamic Hospital In Surabaya A. Yani

Corona Virus Disease2019 (COVID-19) is a disease that shocked the world at the end of 2019. Based on data, positive cases of Covid-19 in Indonesia on July 29, 2021 reached 3,331,206 people, with 3,240,654 Covid-19 patients recovering and 90,552 Covid-19 patients dying. Meanwhile in the city of Surabaya there were 52,782 confirmed cases with 50,894 patients recovered and 1,888 patients died. The high death rate shows that this virus is dangerous, but the cure rate is also high. A survival analysis is needed to determine the patient's survival time (cured) for Covid-19. This research was conducted non-reactively using secondary data in the form of medical records of Covid-19 patients at the Surabaya A. Yani Islamic Hospital in January-July 2021. The results of the study using the Kaplan-Meier method found that the survival time based on age was 12,423 days, the survival time based on gender was 12,078 days, the survival time based on Early Symptoms was 11,461 days and the survival time based on SpO2 capacity was 16,787 days. The conclusions of this study indicate that, age affects the survival time of respondents where the 27-36 year interval has a better survival time than the other respondents' age intervals. The female sex has a better survival time than the male. Initial symptoms determine the severity and duration of recovery for respondents. SpO2 capacity is directly proportional to the degree of patient safety, the higher the percentage of SpO2 capacity, the greater the chance of survival and the lower the percentage of SpO2 capacity, the lower the expectation.

Factors Affecting Community Compliance in Preventing COVID-19 Based on the Health Belief Model

COVID-19 cases in Indonesia are increasing. This has been caused by several factors, such as the lack of compliance and the negative perception that COVID-19 is not a dangerous disease. This study used the health belief model to analyze the factors influencing community compliance in preventing COVID-19. This was a descriptive quantitative study with a cross-sectional approach. The participants included 130 residents of Saronggi District, Sumenep Regency. Data were collected through a questionnaire about compliance and perceptions based on the health belief model. Perceptions of vulnerability, seriousness, benefits, barriers and actions were examined, along with their association with COVID-19 prevention compliance. The data were analyzed using an ordinal regression test. Compliance in preventing COVID-19 was measured as obedient in 75 people (57.69%), quite obedient in 17 people (13.07%), and not obedient in 38 people (29.24%). Meanwhile, based on the findings, the dominant factors that influenced compliance were perceived benefits (p = 0.001), perceived barriers (p = 0.023), and perceptions of action (p = 0.003). Public education about the dangers and prevention of COVID-19 needs to be improved by involving community leaders as role models so that community compliance will increase.

Multi-criteria Decision Analysis for Readiness of COVID-19 Referral Hospital in Jakarta

In early March, Indonesia had reported the first two cases of COVID-19 and this was the beginning for the spread of the COVID-19 outbreak in Indonesia. The need for health services is increasing along with the increasing number of COVID-19 cases in Indonesia. DKI Jakarta is the capital city of Indonesia and is a city with a dense population, causing the transmission of the COVID-19 to be faster than other areas. An assessment of the capacity of health facilities which includes infrastructure and resources is very important to determine the ability of health facilities to manage the rate of spread of COVID-19. This study aims to evaluate the capability of health facilities using the COVID-19 referral hospital readiness index in DKI Jakarta. The data used is the availability of human resources and infrastructure for COVID-19 referral hospitals. Analysis of Geographic Information Systems and Multi-criteria was used to map the readiness index of COVID-19 referral hospitals. The results show that there are no referral hospitals with a high readiness index. There are only 10 referral hospitals with a medium and 92 referral hospitals with a low readiness index. The lack of referral hospitals with a medium readiness index in areas of high vulnerability can have serious consequences in handling COVID-19 cases. Most of the referral hospitals have a low readiness index. However, referral hospitals are capable to reach almost all areas of DKI Jakarta in an emergency condition. It can be concluded that most of the referral hospitals do not have adequate facilities for handling COVID-19 patients.

Identification of Social Support and Knowledge of Covid-19 Survivors with Structural Equation Modeling in R

COVID-19 cases in Indonesia have finally reached a second peak amounting to 4 million cases. A number of the death rate was 3.4 percent, yet the recovery rate was 95.9 percent. The Health Ministry of Republic Indonesia through the Covid-19 Task Force has issued guidelines for preventing and controlling Covid-19 to decrease the death rate and increase the recovery rate. According to the guidelines, a person who undergoes quarantine needs to be provided with health care, and social and psychosocial support. This study seeks to identify the influence of external factors including social support, as well as internal factors including patient motivation, and knowledge on the recovery rate of Covid-19 survivors. The research methods use Structural Equation Modelling to determine the indicators that have the most significant influence on the latent variables of social support, knowledge, and motivation for healing Covid-19. Primary data collection was carried out online with a sample of 176 Covid-19 survivors across Indonesia in August 2021. The methods of the Shapiro-Wilk test for normal multivariate show the p-value at 0.00 significantly satisfies the assumption. The result shows that social support has a significant effect on knowledge with a regression coefficient is 0.263. Knowledge has a regression coefficient is 0.645 for the Healing of Covid-19. In conclusion, the higher social support provided by the patient's external parties: family, surrounding environment, and public health center officers, will impact the higher patient's knowledge and healing of Covid-19 disease. Meanwhile, social support has no significant effect on healing actions.

Evaluating COVID-19 Transmission Prevention Measures in Public Rental Flats (Rusunawa)

Surabaya is an urbanized area with one of the highest numbers of confirmed COVID-19 cases in Indonesia. With Surabaya's healthcare system on the brink of collapse, housing is crucial in extending healthcare facilities. Therefore, adequate housing is the most prioritized prerequisite for people to cope with the transmission rate of the virus. Unfortunately, public rental flats (rusunawa) are among the most vulnerable housing types due to their high density, lack of adequate facilities, and low environmental quality. This paper presents a two-stage investigation to uncover Coronavirus transmission prevention strategies in dense urban settlements, namely in rusunawa. First, the research observes transmission prevention strategies and measures employed by rusunawa residents and managers. Second, the investigation concludes with evaluating the effectiveness of the identified strategies and measures using cross-tabulation analysis. Data for this research was collected using questionnaires distributed among rusunawa residents and managers. Results indicate that effective prevention strategies differ across vulnerability groups. Thus, research findings can potentially help stakeholders and decision-makers enhance their approach to prevent Coronavirus transmission. Not only that, but research findings can also help inform and anticipate future outbreaks.
