APLIKASI MODEL ARIMA GARCH DALAM PERAMALAN DATA NILAI TUKAR RUPIAH TERHADAP DOLAR TAHUN 2017-2022
Get PDFThe Indonesian rupiah (IDR) exchange rate is used to gauge Indonesia's economic stability. Maintaining the IDR exchange rate's stability is critical since it has a direct impact on Indonesia's national monetary situation, particularly during the Covid-19 pandemic. Forecasting the rupiah exchange rate is important to do and is one way to assess government policy. The data series to be used here are IDR exchange rate from the Yahoo Finance. It consists of 271 data taken from August 2017 to October 2022. This study aims to use the Autoregressive Integrated Moving Average (ARIMA) and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) modeling method using the R-studio software and predict the IDR exchange rate. The ARIMA method describes the data based on a certain time series. ARCH-Lagrange Multiplier (ARCH-LM) was applied on the residuals of the best ARIMA model to test whetoer the data is heteroscedasticity. The testing result shows that the residual of the IDR exchange rate is heteroscedasticity. Therefore, the GARCH model can be used to handle it. The results of this study are obtained for the ARIMA(2,1,3) GARCH(3,6) model as the best and describe the actual data pattern with a mean absolute percentage error (MAPE) forecasting value is 1,99%

Terpaan Lingkungan terhadap Kesetaraan Gender dalam Keluarga
Get PDFGender socialization in the family is intended for children to learn about gender roles. It is the family that begins to teach a boy to adhere to masculine traits and a daughter to adhere to feminine traits. This gender learning process is often influenced by factors outside the family which then have an impact on gender equality. Therefore, research was conducted to examine how the environment influences the implementation of gender equality in the family. This study used a combined approach to collect and analyze quantitative and qualitative data because researchers wanted to see trends in data regarding the influence of the environment on gender equality in the family. The results of the study showed that the environment has a significant influence on the implementation of gender equality in the family. The higher the environmental exposure, the higher tendency of respondents not to implement gender equality. This means that there are still differences between boys and girls related to the type of task, type of toys, type of character, pride, and type of color. Every boy or girl already has their own references that have been determined by the family and influenced by the environment. The neighboring factor becomes the dominant factor, in which respondents are aware of these differences, compared to the mass media, friends, and parents. This implies that neighbors are a factor that has a significant influence on respondents in applying differentiation

Get PDFThe pandemic causes the need for new jobs. Most workers from rural areas experienced many layoffs due to the significant reduction in employment opportunities. One of the jobs that can be an option to accommodate these workers is the tourism sector. With community-based tourism, local workers can be absorbed by areas with natural tourism potential. The challenge faced by prospective tourist objects is how significant the potential of the tourism object is and how much the tariff will be set. This study aims to find the economic potential of the object of research used by the micro tourism manager in determining the rates or price ranges used in the sale of culinary or other goods/services. This study uses environmental valuation with the Travel Cost Method to calculate several potential economic objects to be used as the basis for investors to invest in research objects. In addition, managers can also use the average willingness to pay (WTP) as the basis for entrance fees, parking, and culinary prices offered. Considering visitors' preferences is a tourist attraction that looks free; the WTP value for the entrance fee is IDR 0. This study concludes that without managing micro-tourism objects, the value is IDR 63.129.290.00 to IDR71.835.382,00, while if it is managed, the potential increases to IDR5.752.023.104,00. The recommended culinary price is no more than IDR12.084,00, while the parking fee can be collected at IDR 1.000,00.Pandemi menyebabkan perlunya lapangan pekerjaan baru.
