Abstract

The four regression algorithms used in predicting the Composite Stock Price Index (IHSG) have contributed significantly, as the test results show that the Decision Tree algorithm outperforms k-Nearest Neighbor, Linear Regression, and Random Forest, especially in terms of Mean Squared Error (MSE) and R2 score. The stages of data collection, pre-processing, and modeling, followed by model performance measurement, have provided valuable insights into the effectiveness of each algorithm. The success of the Decision Tree in this testing has further propelled its development into a web-based application. This conversion process, following the outlined flowchart, integrates various essential aspects of the model, including user interface and back-end integration, ensuring that the application can be accessed and used efficiently and effectively. Furthermore, the black box testing and User Acceptance Testing (UAT) results, using the Mean Opinion Score (MOS), enhance the validity and reliability of the application. Black box testing involving 2 features with 37 steps demonstrates the system's effectiveness in producing valid outputs, from the initial menu display to the prediction results. Additionally, UAT involving students and entrepreneurs as respondents provides in-depth insights into user acceptance. With a focus on functionality at 97.08%, reliability at 96.09%, and usability at 98.09%, UAT yields high scores in all three aspects, with usability achieving the highest score. These results not only confirm the efficiency of the system in performing its functions but also indicate a high level of user satisfaction, strongly suggesting the potential for widespread adoption of this application in the future.

Abstract

Indeks Harga Saham Gabungan (IHSG) or Indonesia Composite Index (ICI) is part of the macro indicators of a country that describes the economic condition of a country. ICI is an interesting study to research since its existence will be able to show market sentiment regarding an event that occurred in a country. This research tries to predict the ICI in the future based on historical data. The dataset used in this research is publicly available in Yahoo Finance. The experiment is conducted by implementing some regression machine learning algorithms, such as Decision Tree, Random Forest, k-Nearest Neighbor (kNN), and Linear Regression. As a result, Decision Tree has the lowest MSE value compared to other methods: 1268.242. In this research, a website-based application prototype was also developed that can be used to view IHSG graphs and make future predictions, using the 4 (four) tested algorithms.

The sample size was determined using the Cochrane formula with the inclusion criteria of pregnant women with a gestational age of 32-34 weeks. The study was conducted in January 2021. The instrument uses questionnaires and purposive sampling techniques. The Chi-Square and Fisher-Exact tests in this study are used to analyze the relationship between variables. Backward stepwise logistic regression test to determine determinants of postpartum care knowledge. Result: Mothers who had poor knowledge of postpartum care were 45.7%. Poor knowledge is found mainly in the aspects of nutritious food (65.2%), vitamin A (46.7%), and personal hygiene (47.7%). Mothers exposed to digital information are more likely to have knowledge of postpartum care (OR= 2.6; CI 95%= 1,100-6,018; p=0.029). Conclusion: Knowledge of postpartum care during the COVID-19 pandemic in Indonesia is still low and needs to be improved. The use of digital media as a medium for promoting postpartum care has an opportunity to improve maternal and infant health.

Abstract

Profit growth is important for businesses as it can be used to forecast future business plans. Earnings growth is difficult to separate from the company's financial performance as measured by financial ratios. This study aims to determine the effect of accounts receivable turnover ratio, current ratio, debt to equity ratio, and inventory turnover on profit growth. This study has a population of 17 companies over three years (per quarter), and a sample of 204 collected through purposive sampling method, and this study uses data analysis methods, namely multiple regression analysis and panel data with Eviews 12 software. The analysis shows that ITR has a positive and significant effect on earnings growth (Ln), while RTR, CR, and DER have no effect on earnings growth (Ln). All independent variables, namely RTR, CR, DER, and ITR, affect earnings growth (Ln) simultaneously. Earnings growth (Ln) is influenced by the four independent variables by 9%. This shows the capability of financial ratios in anticipating profit increases and can influence investor investment decisions.

Abstract

This study aims to analyze changes in abnormal returns and trading volume Activity (TVA) before and after the announcement of MUI Fatwa Number 83 of 2023 on companies that are targeted for boycott and allegedly affiliated with Israel. The researcher used an event study approach with an event window of 100 days before and 100 days after the announcement of MUI Fatwa Number 83 of 2023 to calculate abnormal returns and trading volume activity. The analysis step carried out in this study is to test the normality of the data first to see if the data has been distributed normally or not, then to test the hypothesis. For normally distributed data, the Paired Sample T-test will be used and the normally undistributed data will use Wilcoxon Signed Rank. The results of this study showed that there was no significant difference in abnormal returns before and after the boycott, but there was a significant difference in trading volume activity before and after. These findings reflect that the boycott has no significant impact and the impact of the boycott is only temporary. However, the action reacted to changes in market sentiment due to the boycott that affected the trading of shares of the boycotted target companies.
