Abstract

The building is a place that is much needed in our daily lives, people choose the building as a place to conduct an event such as a wedding reception, seminar or other event activities. In the process of renting buildings many building providers still use conventional methods in building rental booking transactions, namely by keeping a bookkeeping process of existing rental transactions, this has an impact on recording financial income (financial recapitulation) of building transactions that occur frequently calculation error occurred. This study aims to facilitate the people in the process of leasing building transactions online and build information systems that are able to automatically recapitulate finances based on existing transactions so as to minimize human errors made using the laravel framework. The system was built using the SDLC (System Development Life Cycle) method as well as data collection which was carried out in a study of literature, observation and interviews, with this system making the process of building lease transactions even better than the previous system.

Abstract

Source code plagiarism has become a recurring issue in higher education, particularly in programming-related courses where students may copy portions or entire segments of source code from their peers. This situation creates challenges for lecturers in evaluating the originality of student assignments, especially when dealing with a large number of submissions within limited time constraints. Therefore, this study aims to design and develop a web-based source code plagiarism detection application using the Rabin–Karp algorithm to identify and measure the similarity level between programming code documents. The research employed a qualitative approach through observation, interviews, and literature review, while system development followed the Agile methodology. The developed application was tested using source code files written in C++, Java, and Python programming languages. Black-box testing demonstrated that all system functions operated successfully, including file uploading, preprocessing, tokenization, rolling hash generation, fingerprint matching, and similarity calculation. The validity testing results showed similarity percentages ranging from 2.81%–62.70% for C++ files, 17.26%–54.49% for Java files, and 6.35%–34.89% for Python files. These findings indicate that the application can effectively detect similarities between source code documents and support lecturers in identifying potential plagiarism cases. Furthermore, the Rabin–Karp algorithm proved capable of performing similarity analysis efficiently across multiple programming languages with relatively fast processing time.
