Sistem Repositori Tugas Akhir Mahasiswa dengan Fungsi Peringkat Okapi BM25
Downloads
Abstrak” Saat ini Jurusan Teknik Informatika Universitas 'X' mewajibkan mahasiswa yang telah selesai tugas akhir untuk mengumpulkan hasil karya mereka dalam bentuk softcopy (CD) yang berisi program aplikasi dan dokumentasi, serta hardcopy (dalam bentuk buku laporan dan jurnal). Karya tersebut disimpan di perpustakaan secara fisik dan beberapa data disimpan di Digital Library Universitas 'X'. Namun keterbatasan sistem yang ada saat ini menyebabkan kesulitan pencarian hasil karya tugas akhir, karena teknik/metode yang digunakan untuk melakukan pencarian dibuat dalam bentuk query sederhana dengan kriteria yang masih terbatas, tanpa pengurutan dengan peringkat. Selain itu, kepala lab di jurusan juga menemui kesulitan dalam melakukan pemetaan bidang keahlian dari tugas akhir yang dikerjakan oleh mahasiswa di masing-masing lab. Berbagai permasalahan tersebut melatarbelakangi penelitian ini, sehingga diperlukan adanya sistem yang dapat membantu jurusan dalam menyimpan hasil karya tugas akhir mahasiswa, mempermudah pencarian, serta menampilkannya. Pencarian tugas akhir pada penelitian ini berdasarkan query yang diinput oleh pengguna menggunakan metode pencarian fungsi Okapi BM25. Dengan fungsi peringkat Okapi BM25 maka hasil karya dapat ditampilkan dengan urutan peringkat sesuai relevansinya.

Abstract” Every student in Department of Informatics University 'X' who has completed final project must submit their work in both softcopy (CD) – which containing the documentation and application software – and hardcopy, containing final project documentation and journal report. Currently students hardcopies are stored physically in the university library and some information are stored in the Digital Library System of University 'X'. But there are some difficulties of finding those information in the current system. The system only use simple query method with very limited criteria. The query results are being displayed by the system without any ranking method. In addition, Kalab (lab manager in the department) also encountered difficulties in mapping expertise areas of students final project in their lab. The purpose of this research aims to build a repository system to help the department to store students final project results, also makes it easy to search, display, and being managed. The system also clusters, ranks and displays a set of students final project documents according to some given queries using Okapi BM25 function.
