Weight Calculation

The journal is known as one of the relevant serial literature that can support a researcher in doing his research. In its development journal has two formats that can be accessed by library users namely: printed format and digital format. Then from the number of published journals, not accompanied by the growing amount of information and knowledge that can be retrieved from these documents. The TF-IDF method is one of the fastest and most efficient text mining methods to extract useful words as the value of information from a document. This method combines two concepts of weight calculation that is the frequency of word appearance on a particular document and the inverse frequency of documents containing the word. Furthermore, data analysis of journal title is done by Nave Bayes Classifier method. The purpose of the research is to build a website-based information retrieval system that can help to classify and define trends from Indonesian journal titles. This research produces a system that can be used to classify journal titles in Indonesian language, with system accuracy in determining the classification of 90,6% and 9,4% error rate. The highest percentage result that became the trend of title classification was decision support system category which was 24.7%.

Subject Collection

Di era digital saat ini, sistem alat bantu perpustakaan harus dievaluasi untuk mengetahui kepuasan dan efektivitas penggunaannya. Penelitian ini membahas evaluasi sistem temu balik informasi di Perpustakaan Badan Pengkajian dan Penerapan Teknologi (BPPT). Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif. Data dikumpulkan melalui observasi, studi dokumen dan analisis audio visual kualitatif. Hasil penelitian menunjukkan bahwa dalam hal cakupan, sistem temu balik informasi telah mampu mencakup dan memproses banyak dan beragam koleksi dari berbagai subjek yang digunakan oleh pengguna perpustakaan. Ingat dan presisi juga tinggi dan hasil pengukuran pada jeda waktu pencarian cepat dan efektif dengan waktu rata-rata 0,48 detik. Tampilan katalog juga memudahkan pengguna perpustakaan untuk menggunakan dan mencari informasi meskipun tampak kaku. Katalog online juga telah dapat membantu mengurangi upaya pengguna perpustakaan yang berlebihan dengan tampilan yang akrab serta beberapa klasifikasi sederhana yang mengelompokkan koleksi ke dalam mata pelajaran tertentu. Studi ini memberikan praktik terbaik tentang penggunaan sistem temu balik informasi di perpustakaan pemerintah yang memiliki keunikan dalam hal jenis koleksi, subjek, koleksi itu sendiri dan pengguna perpustakaan.ABSTRACTIn the digital age, library retrieval system tools must be evaluated to find out the satisfaction and effectiveness of its use. This research discusses information retrieval system evaluation at Badan Pengkajian dan Penerapan Teknologi (BPPT) library. The study used qualitative approach with descriptive method. The data was collected through observation, document study and qualitative audio visual analysis. The results showed that in terms of coverage, its information retrieval tool has been able to cover and process numerous and varied collections from various subjects used by library users. Recall and precision were also high and measurement result on search time lag was fast and effective with resulting average time of 0.48 seconds. Catalog interface made it easy for library users to use and search information even though it seemed rigid. Online catalog has able to help reduce library users excess of effort with familiar display as well as several simple classifications categorizing collections into particular subjects. This study provides best practice on the use of information retrieval system for government libraries, in which its uniqueness in terms of collection types, subject, collection itself and library users.
