Abstract

There were many database methods for managing data. They were widespread industries that had a huge success. The method used in this study was the relational database method and the graph database. The relational database method was considered as the standard for over thirty years. The graph database consisted of several components e.g., nodes, edges, and properties that represented the data storage. The graph database provided index-free adjacency, which meant that each element contained a direct pointer which was adjacent to the elements and no longer required an index lookup. These databases can be more scaled to the larger datasets as they generally did not require a "joint" operation. Therefore, they were more suited to manage the fluctuating ad-hoc data with changing schemasKeywords:Relational Databases, Database Graph, Nodes, Edges, and Properties

Abstract

Implementation of Rabin-Karp Algorithm in Plagiarism Detection - Plagiarism is a crime and a scourge of science. To avoid plagiarism in scientific articles, as in the case of this research, string-matching methods can be used. This study aims to implement the Rabin-Karp Algorithm in detecting plagiarism in scientific writing based on the level of text similarity. The Rabin-Karp algorithm was chosen for this research problem because previous studies revealed that the Rabin-Karp premise is to separate the hash value of the input string from the text substring. Assuming they are the same, the character check is performed one more time, and if not, moves the substring aside. The main part of this computation exhibit is successfully calculating the hash of the substring when applied. This research is quantitative. The stages of this research flow were carried out by testing the implementation of the Rabin-Karp algorithm. Based on the calculation above, the percentage of similarity between Test Sentence 1 and Test Sentence 2 is 77.96%. Referring to previous studies, the Winnowing algorithm was found to be better at detecting text similarities than the Rabin-Karp algorithm. This is shown in the results of the similarity detection test of 30 paper documents as test data with the results of the average percentage value. Rabin-Karp Algorithm 41.41% and Winnowing Algorithm 35.15%. This study shows that the Rabin-Karp Algorithm does not work optimally in detecting text similarity, so further research needs additional methods to calculate a good level of similarity to optimize the performance of the Rabin-Karp Algorithm.

Abstract

Media penjualan di toko oleh-oleh kirana masih menggunakan cara yang manual dimana setiap pembeli yang menginginkan oleh-oleh tersebut harus datang secara langsung ke toko kirana sehingga pembeli tidak mengetahui barang apa saja yang tersedia saat ini. Dengan menggunakan e-commerce kegiatan jual beli maupun pemasaran online, di mana e-commerce tersebut akan memperlihatkan adanya kemudahan bertransaksi, pengurangan biaya dan mempercepat proses transaksi Mengimplementasikan e commerce untuk membuat aplikasi penjualan online berbasis android Dengan adanya masalah pada sistem yang sedang berjalan, maka penulis membentuk sistem yang baru Dengan harapan dapat berjalan dengan optimal sesuai dengan yang di butuhkan Toko Oleh-Oleh Kirana dan memeberi manfaat bagi pembeli yang ingin membeli produk-produk, makanan ringan, souvenir, pakaian, minuman khas dari Kota Pagar Alam melihat kondisi permasalahan di atas maka penulis memimplementasikan e-commerce sebagai media penjualan berbasis android pada Toko Oleh-Oleh Kirana sehingga mempermudah pembeli atau wisatawan untuk melihat produk apa saja yang dijual di Toko Kirana, serta melakukan pembeliannya tidak harus datang langsung ke Toko Kirana, melaikan melalui aplikasi penjualan secara online yang telah tersedia.

Abstract

Private universities in Indonesia are essential in meeting the educational needs of the country's increasing number of students. Among the key determinants of student enrollment is the accreditation status of these institutions. This study investigates how accreditation status influences student numbers at private universities in South Sumatra, employing the K-Means clustering method for analysis. Data from various institutions across South Sumatra were collected and analyzed, revealing distinct patterns in how universities are grouped based on their accreditation and enrollment figures. The findings shed light on the significant relationship between accreditation status and student enrollment, offering valuable insights for policymakers and university administrators. These insights can inform the development of effective student admission strategies, ultimately contributing to the growth and success of private universities in the region. This research not only highlights the importance of accreditation but also provides a comprehensive understanding of the factors driving student growth at private universities in South Sumatra.
