Data dan informasi merupakan bagian penting dalam pertimbangan mengambil keputusan terkait penanganan COVID-19. Data COVID-19 baik demografi maupun agregat di Provinsi DKI Jakarta diolah dan dianalisis untuk memberikan informasi mengenai situasi dan kondisi terkini terkait pandemi COVID-19 di Provinsi DKI Jakarta. Data COVID-19 tersebut juga dimanfaatkan untuk analisis prediktif untuk mengetahui perkiraan jumlah kasus COVID-19 di masa depan. Analisis prediktif yang digunakan dalam artikel ini adalah metode Autoregressive Integrated Moving Average (ARIMA). Model ARIMA merupakan salah satu metode forecasting hasil dari perluasan model Autoregressive Moving Average (ARMA) untuk data yang tidakstasioner. Analisis dan visualisasi data dilakukan menggunakan program Python dan Tableau dimana hasil analisis prediktif memperlihatkan tren kasus positif harian yang cenderung naik di kurun waktu 14 hari ke depan dari data yang digunakan. Hasil analisis ini dapat digunakan sebagai pertimbangan bagi pemerintah dalam mengambil kebijakan dan intervensi dalam penanganan COVID-19 di Jakarta, dan untuk masyarakat agar tetap melakukan tindakan preventif dalam mencegah kenaikan kasus, seperti mematuhi protokol kesehatan yang sudah ditetapkan oleh Pemerintah.

Abstract The spread of the COVID-19 started in Wuhan on December 31, 2019, and a powerful outbreak of the disease occurred there. According to the latest data, more than 165 million cases of COVID-19 infection have been detected in the world (last update May 19, 2021). In this paper, we propose a statistical study of COVID-19 pandemic in Egypt. This study will help us to understand and study the evolution of this pandemic. Moreover, documenting of accurate data and taken policies in Egypt can help other countries to deal with this epidemic, and it will also be useful in the event that other similar viruses emerge in the future. We will apply a widely used model in order to predict the number of COVID-19 cases in the coming period, which is the autoregressive integrated moving average (ARIMA) model. This model depicts the present behaviour of variables through linear relationship with their past values. The expected results will enable us to provide appropriate advice to decision-makers in Egypt on how to deal with this epidemic.

The Impact

The novel coronavirus COVID-19 is spreading across the globe. By 30 Sep 2020, the World Health Organization (WHO) announced that the number of cases worldwide had reached 34 million with more than one million deaths. The Kingdom of Saudi Arabia (KSA) registered the first case of COVID-19 on 2 Mar 2020. Since then, the number of infections has been increasing gradually on a daily basis. On 20 Sep 2020, the KSA reported 334,605 cases, with 319,154 recoveries and 4,768 deaths. The KSA has taken several measures to control the spread of COVID-19, especially during the Umrah and Hajj events of 1441, including stopping Umrah and performing this year’s Hajj in reduced numbers from within the Kingdom, and imposing a curfew on the cities of the Kingdom from 23 Mar to 28 May 2020. In this article, two statistical models were used to measure the impact of the curfew on the spread of COVID-19 in KSA. The two models are Autoregressive Integrated Moving Average (ARIMA) model and Spatial Time-Autoregressive Integrated Moving Average (STARIMA) model. We used the data obtained from 31 May to 11 October 2020 to assess the model of STARIMA for the COVID-19 confirmation cases in (Makkah, Jeddah, and Taif) in KSA. The results show that STARIMA models are more reliable in forecasting future epidemics of COVID-19 than ARIMA models. We demonstrated the preference of STARIMA models over ARIMA models during the period in which the curfew was lifted.

Resesi merupakan penurunan secara signifikan dalam kegiatan ekonomi yang tersebar di seluruh aspek ekonomi. Resesi yang berkepanjangan dapat membawa perekonomian ke arah depresi. Indonesia termasuk ke dalam kategori fragile country yang menyebabkan kerentanan untuk masuk ke masa resesi semakin besar. Resesi merupakan bagian dari siklus bisnis yang mungkin akan dialami pada suatu waktu. Penelitian ini menggunakan model ­Generalized Linear Autoregressive Moving Average (GLARMA) untuk mengakomodir prediksi peluang dari fase resesi yang di definisikan dengan metode Bry Boschan dan meramal variabel independen dengan Autoregressive Integrated Moving Average (ARIMA). Variabel yang digunakan yaitu laju inflasi, fed fund rate, transaksi berjalan, harga minyak dunia, dan selisih U.S. 10Year-Bond dengan 3-Month LIBOR. Dari hasil penandaan siklus bisnis pada Produk Domestik Bruto riil, Indonesia mengalami delapan kali resesi sejak tahun 1993Q1-2020Q1 dengan durasi terpendek selama dua triwulan dan terpanjang selama delapan triwulan. Hasil dari model GLARMA(1,0) menunjukkan bahwa resesi di Indonesia didominasi oleh faktor eksternal yang dalam penelitian ini adalah selisih U.S. 10Year-Bond dengan 3-Month LIBOR dan fed fund rate memiliki pengaruh negatif secara signifikan terhadap resesi. Autoregressive lag-1 memiliki pengaruh positif terhadap resesi atau dengan kata lain kondisi yang terjadi pada triwulan sebelumnya berpengaruh terhadap terjadinya resesi di triwulan selanjutnya. Resesi di Indonesia diprediksi terjadi pada 2020Q3.

Abstract Seawater intrusion is one of the most serious issues to threaten coastal aquifers. Tourian aquifer, which is selected as the case study, is located in Qeshm Island, Persian Gulf. In this study, first the vulnerability of the region to seawater intrusion is assessed using chloride ion concentration value, then by using the autoregressive integrated moving average (ARIMA) model, the vulnerability of the region is predicted for 14 wells in 2018. The results show that the Tourian aquifer experiences moderate vulnerability and the area affected by seawater intrusion is wide and is in danger of expanding. It is also found that 0.95 km2 of the region is in a state of high vulnerability with Cl concentration being in a dangerous condition. The prediction model shows that ARIMA (2,1,1) is the best model with mean absolute error of 13.3 mg/L and Nash–Sutcliffe value of 0.81. For fitted and predicted data, mean square error is evaluated as 235.3 and 264.3, respectively. The prediction results show that vulnerability is increasing through the years.

Rainfall Forecast

Climate is an important element for human life, one of them is to agriculture sector. Global climate change leads to increased frequency and extreme climatic intensity such as storms, floods, and droughts. Rainfall is climate factor that causes the failure of harvest in Merauke. Therefore, rainfall forecast information is very useful in anticipating the occurrence of extreme events that can lead to crop failure. The purpose of this research is to model rainfall using autoregressive integrated moving average (ARIMA) model. The ARIMA model can be used to predict future events using a set of past data, including predicting rainfall. This research was conducted by collecting secondary data from Agency of Meteorology, Climatology, and Geophysics (BMKG) from 2005 until 2017, then the data was analyzed using R.3.4.2. software. The analysis result showed that ARIMA model (2.0,2) as the right model to predict rainfall in Merauke. The result of forecasting based on ARIMA model (2.0,2) for one period ahead is 179 mm of average rainfall, 46 mm of minimum rainfall, and 295 mm of maximum rainfall. Thus it can be concluded that the intensity of rainfall in Merauke has decreased and there was a seasonal shift from the previous period.
