Abstract

Recommender system or recommendation system is becoming an increasingly important technology on e-commerce websites to help users find products that suit their preferences. However, the growing number of users and products makes finding the right product difficult. Therefore, this study aims to develop a recommender system on e-commerce websites using collaborative filtering and deep learning techniques. Collaborative filtering is used to find similarities between users based on their preferences, while deep learning is used to improve the performance of the recommender system in generating more accurate recommendations. The test method is carried out by comparing the performance of the recommender system developed with the recommender system that already exists on the e-commerce website. The results of the test show that the recommender system developed is able to provide recommendations that are more accurate and more in line with user preferences compared to the existing recommender system.

Abstract

This study aims to analyze the financial performance of Indonesian manufacturing companies before and after the global economic crisis in 2008. In this study, financial performance is measured by Return on Assets (ROA), Return on Equity (ROE), and Net Profit Margin (NPM). By comparing the average ROA, ROE, and NPM before and after the crisis, the results of the descriptive analysis were tested. It can be seen that ROA, ROE and NPM after the crisis were higher than before the crisis. As a result, post-crisis financial performance has improved compared to before the crisis. Based on the descriptive analysis, it is known that the financial performance of manufacturing companies after the crisis is better than before the crisis. Based on the t test, the results of ROA, ROE and NPM tests were obtained as follows. First, Post-crisis ROA is higher than before the 2008 global economic crisis, and the increase is said to be large. Second, post-crisis return on equity appears to be higher than before the global economic crisis, but this is not statistically significant. Third, post-crisis NPM also appears to be larger than before the crisis, but not statistically significant. The results of the t test show that financial performance as measured by ROA has improved after the crisis compared to before the crisis.
