Abstract

This study identifies whether there are differences in the Average Abnormal Return and Average Trading Volume Activity before and after the 2024 presidential and legislative elections in Indonesia. The study includes samples of infrastructure companies listed on the Indonesia Stock Exchange during February 2024 and analyzes the data utilizing the Wilcoxon signed-rank test. Based on signalling theory, general elections can inform investors and affect investment decisions. However, the results of the study exhibit no significant difference yet align more with the semi-strong form of the efficient market hypothesis, where stock prices reflect all publicly available information, including expectations of government policies that impact the market. This finding also reflects the precautionary motive of investors, where market participants anticipate political uncertainty by adjusting their investment strategies before the 2024 election. This indicates that political factors affect market sentiment but do not necessarily lead to significant volatility.

Abstract

This study aims to analyze the implementation of the ERP-SAP system to improve the accounting information quality of Perum Jasa Tirta I Malang. This study applies a qualitative method with a descriptive approach, in which information is collected through semi-structured interviews and direct observation of relevant staff in the accounting division. The analysis is based on COSO theory to evaluate internal controls that support ERP-SAP implementation in the context of accounting information quality, including aspects of relevance, reliability, comparability, verifiability, timeliness, and understandability. The results exhibit that the implementation of ERP-SAP results in a positive effect in terms of time efficiency, accuracy of financial reports, and the ability to make real-time data-based decisions despite the challenge in human resource (HR) adaptation that needs resolution to maximize the use of the system.
