Abstract

The security system within a company is the top priority, one of its application is in web media, where it exist various confidential information in it, such as user information on the company PT. One Standard Group PTE LTD must be kept confidential not to fall into unauthorized parties, therefore a security system to address the information security is needed. The security system of modern symmetric key cryptography algorithms is considered to be able to overcome these problems which are generally divided into two, namely Data Encryption Standard (DES) dan Advanced Encryption System (AES). From the two algorithms, the author makes comparisons to obtain a more efficient algorithm in terms of security and times. The method that the author used in this research is Extreme Programming Research Methodology, with a qualitative methodological analysis technique, and in data collection author uses direct observation and literature study. The system that the author created applies additional security for user information which will be directly stored with the AES method and the DES method and the system will display the processing time of both. The conclusion that the author can achieve from this thesis is AES method cryptographic algorithms are more secure than the DES method because the AES method has double protection, but from the time aspect efficiency, the DES method cryptographic algorithms are more efficient.

Abstract

At  present  the  development  of  digital  technology  and  telecommunications  is  progressing  very  rapidly throughout the world, making almost in every country always closely related to technology in their daily lives, including Indonesia. Utilization of computer applications in everyday life has become a necessity. For this reason, the issue of security and confidentiality of data and information is very important. Personal data should not be known by others to suppress the occurrence of data that is misused and used. It needs to be protected and restricted from anyone who can access important data. In this study, the authors developed a login data security system application with the AES algorithm method to assist individuals in maintaining important data, especially passwords they have. In addition this application uses a MySQL database as a means of storing data, and PHP, HTML as a programming language, and CodeIgniter as a framework for supporting system development. This  research  was  conducted  by  utilizing  the methods  in  collecting  data,  namely,  literature  study  and documentation. And utilizing the AES algorithm as a data analysis and measurement technique The design of the application that the authors propose will include a system architecture, a system description using UML diagrams, namely use case diagrams, activity diagrams, and class diagrams, there is also a design interface and program flow design to explain how the program can run and how the program displays when viewed by the user, and there is a system implementation that covers hardware specifications, installation guides, and usage guides. The cryptographic application that the authors produced through this research is intended to be able to provide a security system solution that can maintain data security on the login system so that users can stop using passwords that are weak and repetitive, so users can keep their passwords safer.

Abstract

This study developed a web-based personal finance application integrated with semantic retrieval using embedding and Large Language Models to address limitations in conventional keyword-based search. The system was developed using the Extreme Programming approach to ensure iterative development, rapid feedback, and adaptability to user requirements. The application was designed using a client–server architecture and implemented to support transaction recording, financial management, and contextual data retrieval. Financial transaction data were preprocessed and converted into vector embeddings to capture semantic meaning, enabling more flexible and accurate search using natural language queries. The system utilized a vector database with pgvector extension to store embeddings and perform similarity search. Evaluation was conducted using the RAGAs framework with 100 financial transaction data and 20 query scenarios. The results showed that the system achieved a context recall of 0.81, context precision of 0.70, faithfulness of 0.83, and answer relevancy of 0.84. These results indicate that the system was able to retrieve relevant contextual information and generate consistent and accurate responses. Furthermore, the implementation demonstrated improved effectiveness in organizing, managing, and retrieving financial data compared to traditional methods. Overall, the proposed system successfully provided a more efficient and context-aware solution for personal financial management and information retrieval.
