Abstract

This research aims to forecast fluctuations in the price of West Texas Intermediate (WTI) crude oil within the potential threat of World War III by utilizing the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) method. Using daily closing price data of WTI crude oil from January 2022 to March 2025, consisting of 850 observations, this study employs the ARIMA-GARCH model to capture the patterns and volatility of the time series data. Based on the conducted analysis, it is concluded that the ARIMA (2,1,2) and GARCH (1,1) models demonstrate optimal performance, with a MAPE value of 13.71%, indicating a good prediction accuracy level. The forecast for the next two years shows a trend of price increases starting from Q2 2025 through Q4 2027. This research demonstrates how geopolitical tensions, particularly the Russia-Ukraine war and Middle Eastern Conflicts, can affect global oil price volatility while highlighting the GARCH model’s effectiveness in capturing heteroskedasticity in highly fluctuating financial data.

Abstract

This study aims to analyze the influence of leadership and communication styles on employee satisfaction in cafes in Tebing Tinggi City. The rapidly growing cafe industry demands effective human resource management, particularly in creating a supportive work environment through good leadership and effective communication. This study uses a quantitative approach with a sample of 50 permanent employees from 10 cafes selected using a purposive sampling technique. The research instrument was a questionnaire with a 5-point Likert scale, and data were analyzed using the Partial Least Squares (PLS) technique through the SmartPLS 3.0 application. The results of the study indicate that leadership style has a significant effect on employee satisfaction with a t-statistic value of 4.770 (p = 0.001), and communication also has a significant effect with a t-statistic value of 4.848 (p = 0.000). The research model has an R² value of 0.796, which means that 79.6% of the variability in employee satisfaction can be explained by leadership style and communication. The Q² value of 0.7960 indicates that the model has strong predictive relevance. These findings indicate that leadership style and communication play an important role in increasing employee job satisfaction, which impacts their performance and loyalty to the organization. This study recommends that café managers continue to improve the quality of leadership and internal communication to create a more productive and harmonious work environment.

Abstract

Currently, many schools do not provide financial knowledge to their students. Students should learn about investment early in accordance with the development of technology and science. Therefore, many students do not understand investment and capital markets, so they do not have the enthusiasm to save for the future. The purpose of this program is to increase students' knowledge about investment in the capital market and reduce the impact of low interest in investing in the capital market. In addition, the purpose of this service is to provide education and training on investment in the capital market to students of SMA Negeri 1 Dolok Masihul, Serdang Bedagai Regency. This activity is expected to motivate students to try to invest in the capital market.
