Stocks are one of the best-known forms of investment and are still used today. In stock investment, it is necessary to know the movement and risk of loss that may be obtained from the stock investment so that investors can consider the possibility of profit. One way of calculating risk is to use the Expected Shortfall (ES). Because the stock movement is in the form of a time series, a model can be formed to predict the movement of the stock which can then be used for ES calculations using time series analysis. The purpose of the study was to determine the expected shortfall value of MYOR shares using time series analysis. The data used for this research is the daily closing price of shares for three years. In the time series analysis stage, the models used in predicting stock movements are Autoregressive Integrated Moving Average (ARIMA) for the mean model and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) for the volatility model. The average value and variance obtained from the model are then used in calculating the ES on MYOR stock. Based on the results of the study, it was obtained that MYOR's stock had an ES of 0.050772. This means if an investment is made for MYOR shares of IDR 1,000,000.00 for 37 days (5% of 751 days) for an investment period with a 95% confidence level, the expected loss to be borne by the investor is IDR 50,772.00.

Sustainable development has emerged as a critical global concern, particularly in the context of energy consumption and environmental quality. In Southeast Asia, the heavy reliance on fossil fuels, especially oil, poses significant challenges to achieving sustainability goals. This study investigates the impact of renewable energy consumption, natural resource rents, and economic globalization on the Sustainable Development Index (SDI). Using panel data from five ASEAN countries—Indonesia, Malaysia, Thailand, Singapore, and the Philippines—from 2000 to 2020, the analysis applies panel quantile regression to explore the relationships among the variables. The findings reveal that renewable energy consumption and economic globalization contribute positively to the Sustainable Development Index, whereas natural resource rents exhibit a negative impact. A distinctive aspect of this research is its use of the Sustainable Development Index as a metric, offering a novel approach not extensively employed in prior studies. The insights derived from this study can inform the development of policies promoting sustainable development, particularly through adopting renewable energy and managing economic globalization. Additionally, the findings underscore the need to address the adverse effects of natural resource exploitation to enhance regional sustainability outcomes.

Inflation and unemployment are significant challenges faced by both developing and developed countries. This study analyzes the causal relationship between inflation, as measured by the Gross Domestic Product (GDP) Deflator, and open unemployment in Indonesia. Using a Vector Autoregressive (VAR) panel model, the analysis is based on panel data from 34 provinces from the first semester of 2015 to the second semester of 2022. The results of statistical tests indicate a unidirectional causality, with inflation Granger-causing unemployment, but not vice versa. This finding is further supported by the Vector Autoregression estimates, where Lag 4 reveals that unemployment is primarily influenced by inflation, while inflation remains unaffected by unemployment. To address the issue of unemployment, policymakers should prioritize controlling inflation and keeping it within manageable limits, as reducing inflation could contribute to improved unemployment rates. Future research should explore the relationship between inflation and unemployment through qualitative interviews with individuals who have experienced both issues to understand their daily impacts better.

Covid-19 is an infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The virus was first discovered in Wuhan, China in late December 2019. Because the virus spreads so quickly through droplets released by infected humans, the WHO (World Health Organizer) later announced that the disease is becoming an emergency requiring infected countries to impose a lock down system to slow the spread of the virus. The COVID-19 virus was first identified in Indonesia in March 2020 and the government imposed restrictions on activity and made recommendations for health protocols to be adhered to to date to prevent spread. One of the health protocols that must be adhered to is to wash your hands 6 steps properly. Hand washing can be done with soap and clean running water, or by using a hand sanitizer. The use of hand sanitizer is easy and practical because it can be taken anywhere and does not take a long time, but its availability is limited and the price is fairly expensive. Therefore, we want to teach children and teaching staff at Miftahul Khoeriyah how to make hand sanitizer independently with the basic ingredients of aloe vera, alcohol, and essential oil. This activity was carried out on September 5, 2021 located in Madrasah Miftahul Khoeriyah Bungursari Subdistrict.
