JURNAL: PERANCANGAN SISTEM PENENTUAN SIMILARITY KODE PROGRAM PADA BAHASA C DAN PASCAL DENGAN MENGGUNAKAN ALGORITMA RABIN-KARP

Abstract

This research aims to design and implement an application that can determine the percentage of similarity to the C code and post using Rabin-Karp algorithm. In this application the input use is a code C and Pascal who type *. C and *. Pas, while the output of the application is in the form of percentage similarity of both the tested code and the processing time required in each process. The results of this study are called "Similarty Checked" is developed using Borland Delphi 7. This application can determine the percentage of similarity of code under test. On the application of "Similarity Checked", there are 5 stages of a process called preprocessing to prepare the program code before checking the similarity of two documents, that are: case folding, filtering, parsing, k-gram, hashing and two-stage process to obtain the percentage of similarity checking code ie: checking the rabin-Karp algorithm and determination of the value of similarity calculated by dice similarity coeficients. Testing is done by trying out some of the code C and Pascal programs are different, and by using k-gram values are different. Based on the testing that has been done, showed that the application has been designed to determine the percentage of similarity of code C and Pascal programs were tested.

Keywords: similarity, similarity checked, rabin-karp, code program, string matching, k-gram

Pendahuluan

Dengan perkembangan dunia teknologi dewasa ini yang semakin pesat membawa banyak pengaruh baik itu positif maupun negatif. Salah satu dampak negatif dari perkembangan teknologi adalah memudahkan orang dalam melakukan kecurangan-kecurangan yang dapat menimbulkan kejahatan. Kecurangan yang sering terjadi akibat perkembangan teknologi adalah menjiplak hasil karya orang lain yang kemudian menjadikan seolah-olah hasil karyanya sendiri. Pencegahan dalam pencontekan merupakan salah satu cara yang paling efektif untuk meningkatkan kualitas pendidikan, sehingga mahasiswa institusi pendidikan dapat mengembangkan kreativitas serta imajinasinya secara alamiah.
