<![CDATA[Anxiety is a condition that arises when there is a threat of helplessness, feelings of isolation. Anxiety is also a matter of excessive concern and internalized as well as a variety of summative symptoms that cause significant disturbances in social or work functions that cause a decrease in interest in learning mathematics in students. Interest has a very important role in the learning process because interest is one of the determining factors in the success or action of the instructor's objectives to be achieved. Students who are not interested in the subject matter will show less sympathetic, lazy and not passionate attitudes. The data collection method uses a questionnaire for learning interest variables. The purpose of this study was to determine the relationship of student anxiety to interest in learning mathematics. The research subjects were 30 students. Based on the results of the study, it was concluded that: (1) there was a relationship of students 'anxiety to the interest in learning mathematics, or in other words the interest in learning mathematics at all was related by students' anxiety in their interest in learning mathematics in the face of examinations, especially in mathematics; (2) there is no relationship of interest in learning mathematics, or in other words there is no relationship of interest in learning mathematics that students have in learning mathematics. The relationship of anxiety that occurs between mathematics learning interest and anxiety is negative 0,417; (3) as a stimulus, anxiety about learning interest has a proven influence on the relationship of students' anxiety to mathematics learning interest]]>

<![CDATA[Stock is an investment in the capital market that is very promising for investors. Investors can also get high returns from the shares invested. However, this stock price is not always stable, it can go up and down drastically. The purpose of this study is to predict stock prices because they often experience instability. The method used in this research is using the Exponential generalized autoregressive conditional heteroscedasticity (EGARCH) model with the Quasi Maximum Likelihood (QML) method. The result of this research is the implementation of this model. The EGARCH model used is the stock price index model that is formed, namely the autoregressive integrated moving average (ARIMA) (0, 1, 2) EGARCH (1.4). The conclusion from the results of the research that predictions using the ARIMA model (0, 1, 2) EGARCH (1, 4) is the best model in accommodating the asymmetric nature of the volatility of the stock price index. The results of this egarch model show more optimal prediction results seen from an error of 3% compared to other modes such as the arch model and the GARCH model.]]>

<![CDATA[Cabbage is a seasonal plant that contains vitamin A, vitamin B complex, iron, potassium, rivoplafin and folic acid. The problems that often occur with cabbage are pests and diseases which are a serious problem, if not handled properly, the plants may die or not grow properly. Diseases that often attack cabbage are wilting leaves, root rot, fruit and flowers. The limited time of an agricultural expert is an obstacle for farmers to carry out consultations to solve a problem to get the best solution. The process of diagnosis with the help of experts can be applied to the Dempster Shafer method. The Dempster Shafer method is a solution in diagnosis because this method can provide additional information in the form of the percentage of confidence in the disease suffered by an object. The results of this study indicate that from the symptoms obtained using the Dempster Shafer method in 3 cases given by farmers, the percentage of confidence was 82% for wet rot disease, 73.3% for black leg rot disease and 73% for powdery mildew disease, so this method assessed can be applied to the diagnosis of diseases in cabbage plants]]>
