Abstract

This study analyzes the relationship between market sentiment, trading volume, and stock volatility on the Indonesia Stock Exchange (IDX) using the Vector Autoregression (VAR) model. The research addresses the complexity of these interdependent variables and their impact on market dynamics, aiming to provide insights for investors, regulators, and policymakers. The objective was to evaluate how changes in market sentiment affect trading volume and stock volatility and how these variables interact over time. The VAR model was applied to daily and weekly data on market sentiment, trading volume, and stock volatility from IDX. Results indicate that positive sentiment generally increases trading volume and stock volatility, while negative sentiment tends to reduce trading activity and escalate volatility. The findings also highlight the significant role of market liquidity, as trading volume impacts volatility by improving market stability. This study underscores the importance of sentiment analysis in investment strategies and market regulation, suggesting that maintaining market liquidity and stabilizing sentiment can enhance market efficiency and stability. The implications of these results are critical for improving risk management and informing investment decisions in the Indonesian capital market.

Abstract

The purpose of this paper is for teachers to create their own teaching and evaluation materials using iSpring. This ability is very necessary considering that students are now a generation that is already familiar with the internet since they were born. While the teachers are a part of the digital immigrant generation, which was born before the internet developed rapidly. The method used in the form of training and mentoring was carried out by two English Education Lecturers and a Lecturer from the Faculty of Engineering which was attended by 36 junior high school teachers from both the city of Tuban and from other sub-districts around Tuban and held for four meetings. To find out the level of satisfaction of the training, participants were given a quiz and interview. The results of this training showed that most participants felt very enthusiastic, and could make their own material and evaluation in teaching English. After that they also managed to publish it in a format compatible with Android. This is very important because it is a combination of CALL (Computer Assisted Language Learning) and MALL (Mobile Assisted Language Learning), which means that this project uses computer devices and the results can be applied in the form of mobile (HP).
