Prediksi Akhir Pandemi COVID-19 di Indonesia dengan Simulasi Berbasis Model Pertumbuhan Parametrik

Abstract

This research aims to predict the end of the COVID-19 pandemic in Indonesia based on parametric growth models. The models are chosen by considering their fitness with the data of Taiwan which is believed to have passed over the peak of the pandemic and have gone through all phases in the growth curves. The models are parameterized using the nonlinear least squares method. The deviation and confidence interval of each parameter is estimated using the k-fold cross-validation and the bootstrap techniques. Using the total cases per million population data from March 2 to June 18, 2020, it was found that two growth models fit the data, i.e. logistic and modified Gompertz, where the latter performs better. Using the information about the deviation of each model parameter, a simulation model is developed to predict the time at which the total cases curve starts to flatten, which is an indication of the end of the pandemic. It was found with 95% confidence level that based on the modified Gompertz model the pandemic will end somewhere between March 9 – September 7, 2021 with total cases per million of 206 - 555. Meanwhile, based on the logistic growth model, the end of the pandemic is between August 28 – September 23, 2020 with total cases per million of 180 - 375. This model can be extended by making comparative scenario with Taiwan based on measures that represent the quality of the pandemic mitigation such as test ratio and the intensity of social restriction.

Spatial differentiation and determinants of COVID-19 in Indonesia

“…Alpha, Beta, Gamma, Gamma, and Delta variants [ 107 ]. This step could be better than simply referring to pandemic prediction models, which only consider virus transmission based on increasing rates of daily cases until the saturation point is reached and mostly miss, especially those created during the early stage of the pandemic [ 108 – 110 ] owing to insufficient attention to overfitting. The GWR spatial interaction model can serve as input for the development of a pandemic model for Indonesia, which can determine up to 70% of the spreads of COVID-19 pandemic cases.…”

Developing operational accounting competencies during the pandemic using emergency online learning

“…If it is assumed that the COVID-19 pandemic will not be over yet, the government is likely to extend the online learning period. Based on the forecast, this pandemic may end in September 2021 (Pratikto, 2020). This prediction implies that online learning would last for almost four semesters, or two years.…”

Respon Mahasiswa Pada Pembelajaran Hybrid Pasca Pandemi Covid-19

“…Oleh karena itu, kementrian Pendidikan dan Kebudayaan (Kemendikbud) mengeluarkan surat edaran nomor 36962/MPK.A/HK/2020 tentang pembelajaran secara online (Ismunandar dkk., 2021). Namun pada awal bulan Maret 2021 kasus Covid-19 sudah mulai melandai (Pratikto, 2020). Hal ini berdampak pada perubahan tindakan dalam pembelajaran.…”
