Abstract

Hampir 7 bulan Pandemi COVID-19 yang melanda Indonesia tidak hanya berdampak pada sektor ekonomi yang terdampak tetapi juga sektor pendidikan. Di bidang pendidikan, pembelajaran tatap muka di sekolah bergeser menjadi pembelajaran online atau learning from home (LFH). Mau tidak mau, guru, siswa, dan orang tua harus dilibatkan dalam proses pembelajaran agar kegiatan belajar dari rumah (BDR) tetap berjalan efektif. Menjadi guru bagi sebagian orang di tengah pandemi tentu tidak mudah. Harapan yang tinggi membutuhkan kesabaran yang luas, sehingga tidak jarang mengeluhkan tidak efektifnya belajar dari rumah. Bagi guru, kegiatan BDR tentu sangat menyiksa, biasanya bertatap muka dengan siswa kini hanya bisa menyapa lewat online. Membaca nyaring merupakan kegiatan sederhana yang dilakukan tidak lebih dari 10 menit sehari tetapi jika dilakukan terus menerus dapat merangsang belajar membaca pada anak. Belajar membaca membutuhkan proses yang panjang dan kompleks, dari membaca anak memiliki perbendaharaan kata yang banyak sehingga mampu membaca meningkatkan kemampuan bahasanya. Jika kecerdasan bahasa anak sudah tercapai, tidak sulit bagi anak untuk belajar mengenal matematika. Masalahnya adalah banyak dari kita mendefinisikan matematika hanya dalam istilah kata-kata saya (kali, bagi, tambah, kurangi) ketika matematika ada di sekitar kita. Akibatnya, anak-anak dapat mengerjakan matematika tetapi tidak menyukai matematika. Melalui kegiatan membaca nyaring diharapkan anak mendapatkan dua rangsangan kecerdasan sekaligus yaitu kecerdasan bahasa dan kecerdasan matematis logis sehingga proses BDR terasa lebih menyenangkan. Kata kunci : Matematika logis, Membaca nyaring, Anak usia dini

Abstract

Background of the study: the aim of this research is to find out whether there is a relationship between self-efficacy and mathematics anxiety and aims to see a picture of students' self-efficacy and mathematics anxiety. The method used in this research uses a quantitative approach. The population and sample in this research were 189 Bina Dharma Jakarta Middle School students. Data were analysed using SPSS version 27 software with correlational techniques. The findings in this research are that there is a significant relationship between self-efficacy (X) and mathematics anxiety (Y), seen from the contribution made by self-efficacy of 17.6% to mathematics anxiety. The relationship between levels of self-efficacy and mathematics anxiety is in the moderate relationship category with a significance value of -0.419 (negative), so it can be stated that an increase in students' self-efficacy causes a decrease in mathematics anxiety.

Abstract

Dengue Hemorrhagic Fever (DHF) is an infectious disease that remains a serious public health problem in Indonesia, particularly in West Java Province. This study aims to model the number of DHF cases using Gaussian, Poisson, and Compound Poisson Tweedie regression methods based on 2023 data sourced from the West Java Central Statistics Agency (BPS) and the West Java Provincial Health Office. Predictor variables used include humidity, rainfall, real per capita expenditure, poverty ratio, population density, percentage of households with clean and healthy lifestyles, ratio of health facilities, and average altitude of the area above sea level. The analysis results indicate that Gaussian and Poisson regression are less suitable for use because they are unable to handle overdispersion in the data. The Compound Poisson Tweedie model provides the best performance with the smallest Akaike Information Criterion (AIC) value. Three variables that significantly influence the number of DHF cases in West Java in 2023 are rainfall, real expenditure per capitaand the ratio of health facilities, so that the resulting model equation is  (2.233 plus 0.001387 times rainfall plus 0.000022 times real per capita expenditure minus 0.015250 times health facility ratio), indicating that rainfall and expenditure increase DHF cases, while more health facilities reduce them.

Abstract

Dengue Hemorrhagic Fever (DHF) remains a major health problem in West Java Province, which has a tropical climate and dense population. This study aims to model DHF cases using Gaussian, Poisson, and Negative Binomial regression. The data used include the number of DHF cases in 2024 as the response variable and eight predictor variables, namely humidity, amount of rainfall, real expenditure per capita, poverty ratio, population density, percentage of households with clean and healthy lifestyles, ratio of health facilities, and average height of the area above sea level (ASL) according to rainfall stations. Data were obtained from the Central Statistics Agency (BPS) and the West Java Provincial Health Office. The analysis results showed that Poisson and Gaussian regression were less suitable because they were unable to handle overdispersion in the data. The Negative Binomial model provided the best results with the smallest AIC value. Two variables that significantly influenced the number of dengue cases were population density (variable 5) and the ratio of health facilities (variable 7)

Abstract

A Foreign exchange reserves are a vital instrument in maintaining Indonesia's macroeconomic stability, particularly in mitigating external turmoil and stabilizing the rupiah exchange rate. This study aims to analyze the factors that affect Indonesia's foreign exchange reserves position for the period from January 2022 to August 2025 using the Error Correction Model (ECM) method. Independent variables used include the Consumer Price Index (CPI), the rupiah exchange rate against the US dollar (IDR/$), and the policy rate (BI Rate). Data was obtained from the publication of Indonesian Economic and Financial Statistics (SEKI) of Bank Indonesia. The results of the Dickey-Fuller Augmented Stationarity test showed that all variables were stationary at the first difference, while the Engle-Granger co-integration test confirmed the existence of a long-term relationship between the variables. The results of the estimation indicate that, in the long term, no variables have a significant impact on foreign exchange reserves. However, in the short term, the exchange rate has a positive and significant influence, while the policy rate has a negative and significant effect on Indonesia's foreign exchange reserves. A value speed of adjustment indicates that short-term imbalances are corrected towards long-term equilibrium each month, indicating a swift adjustment mechanism.
