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.

The purpose of this study was to explore the effectiveness of artificial in-telligence in detecting malware and improving cybersecurity in computer net-works. Success rate in detecting and preventing malware attacks on computer networks using AI-based methods. The time it takes to detect and prevent malware attacks on computer net-works using AI-based cyber protection methods. Furthermore, the selection of two types of malware that are often found on computer networks, namely Trojans and Worms, and data sampling was then test-ed on a simulation system. In this study, three different AI techniques were applied, namely Support Vector Machine, Neural Network , and Decision Tree to detect malware on computer networks.

Abstract

Dalam era digital saat ini, keamanan informasi menjadi hal yang sangat penting untuk diperhatikan. Terdapat banyak metode untuk menjaga keamanan informasi, namun masih banyak juga kerentanan yang dapat dimanfaatkan oleh pihak yang tidak bertanggung jawab. Teknologi blockchain memberikan solusi dengan menyediakan sistem keamanan informasi yang kuat dan handal. Teknologi blockchain dapat digunakan untuk memastikan integritas dan validitas data yang disimpan. Hal ini dapat dilakukan dengan cara menyimpan data dalam bentuk blok yang tersambung satu sama lain dan menggunakan enkripsi untuk menjaga privasi. Selain itu, sistem terdesentralisasi yang ada pada teknologi blockchain membuatnya sulit untuk diubah atau dihapus oleh pihak yang tidak bertanggung jawab. Penerapan teknologi blockchain pada sistem keamanan informasi dapat dilakukan pada berbagai sektor, seperti perbankan, perdagangan, dan pemerintahan. Dalam sektor perbankan, teknologi blockchain dapat digunakan untuk menjaga integritas data transaksi dan memastikan bahwa transaksi yang dilakukan benar-benar valid. Dalam sektor perdagangan, teknologi blockchain dapat digunakan untuk memastikan bahwa barang yang diperdagangkan benar-benar asli dan memiliki sumber yang dapat diverifikasi. Dalam sektor pemerintahan, teknologi blockchain dapat digunakan untuk menyimpan dan memverifikasi data pemilihan, serta memastikan bahwa hasil pemilihan benar-benar valid dan representatif.
