Abstract

Stocks are evidence of ownership of the capital or funds of a company or institution and are represented by a document that includes the par value, the company name, and the rights and obligations described for each owner. Since so many factors affect the rise and fall of stock prices, investors should pay attention to the factors that influence the rise and fall of stock prices to avoid incurring losses or profits when buying and selling stocks. The rise and fall of stock prices can be analyzed with Markov switching regression by trying all possible placements of factors to get the best subset. Public holdings will continue to increase due to nation-building and Sharia Bank Indonesia (BRIS) stock price appreciation. This study aims to determine the impact of increases and decreases in the closing price of BSI stock. The modeling used in this study is Markov switching regression using the best subset approach. The data used in this study are secondary in the form of daily data for the closing price of Bank Syariah Indonesia shares, Inflation, BI Rate, Selling Exchange Rate, Money Supply, and Gross Domestic Product (GDP). Data are obtained from the official BPS website. The results of this study show that Markov switching regression modeling can identify the feasibility of regimes as "bull" and "bear" periods. State 2 indicates an uptrend or "bullish," and state 1 indicates a downtrend or "bearish." The best subset approach obtains the best model with the lowest SSE value. The study concluded that the statistical modeling results of  BSI stock's closing prices during "bull" and "bear" periods provide significant predictors: BI Rate, Selling Exchange Rate, and Money Supply.

Abstract

This study aims to analyze and understand the influence of compensation, work environment, and motivation on teacher performance at the Nurul Ulum Ngampon Foundation. The quality of education is highly dependent on teacher performance as the spearhead in the learning process. Teacher performance is influenced by various complex factors, including the welfare received, work environment conditions, and the level of internal and external motivation possessed. This study uses a quantitative approach with a survey method, which involves the active participation of teachers at the Nurul Ulum Ngampon Foundation. The collected data were then analyzed using multiple linear regression techniques with the help of SPSS statistical software. This analysis aims to identify the relationship between the independent variables (compensation, work environment, and motivation) with the dependent variable (teacher performance). The results of this study are expected to provide valuable recommendations for the foundation in an effort to improve teacher welfare, create a more conducive work environment, and increase work motivation. Thus, it is hoped that teacher performance can be significantly improved, which will ultimately contribute to the achievement of better educational goals at the Nurul Ulum Ngampon Foundation. This study is also expected to be a reference for further research in the field of human resource management, especially related to the factors that influence teacher performance.
