Abstract

The continuous development of information technology has an impact on the security of sensitive data and information. Cryptography is one of the relevant techniques to maintain data security and confidentiality. The encryption process converts the original data into an unintelligible format called chipertext, while the decryption process converts the chipertext back into the original data or plaintext. This research designs a cryptographic application using 128 bit AES algorithm to increase the security and trust of users in sending and storing text data. This application helps users protect data and provides a high level of security. The research method used is a literature study. The object-oriented system design analysis technique uses UML to model the system structure. The test results show that the encryption and decryption process runs according to the functionality. Overall, this application can provide confidence to users in securing text data through the encryption and decryption process. This research is expected to be an effective solution for individuals and organizations in maintaining the confidentiality of information. This application is also expected to adapt to the ever-changing development of security technology, so that it remains relevant and effective in the future.

Abstract

Small Medium Enterprise (SME) frequently still use manual recording to manage staff attendance and payroll, which leads to errors and inefficiencies. The goal of this research is to create a mobile web payroll system that is integrated with an Android application based on QR codes to enhance the accuracy and efficiency of payroll processing for employees of small and medium-sized businesses. The attendance application was developed in Android Studio with the Java programming language, while the payroll system was developed with HTML, CSS, and JavaScript. A cloud-based database platform called Firebase is utilized. This research uses the Unified Modeling Language (UML) modeling method. The attendance application is able to record employee attendance automatically through QR code scanning. The payroll system provides full control for SME owners, allowing the process of controlling, monitoring, and printing accurate attendance and payroll reports. The use of this attendance application and payroll system will reduce manual errors, improve operational efficiency, and provide real-time control to SME owners. The integration of the attendance application and employee payroll system is very important to improve the competitiveness and adaptability of SMEs in the digital era. Keywords— SME, QR code, Attendance recording, Employee payroll
