Abstract

The development of information technology has significantly changed how information is accessed, necessitating readers to absorb content efficiently and make quick decisions. To address this challenge, this research developed a text summarization system specifically for Indonesian scientific articles using a web-based implementation of the TextRank and TF-IDF algorithms. TextRank was selected for its capability to identify key sentences without requiring training data, while TF-IDF was employed to weight words based on their frequency within the document. The dataset comprised 100 scientific articles in Indonesian from the Unimed Kode Journal, covering the years 2022-2024. The summarization process included several critical stages: text preprocessing, TF-IDF weighting, cosine similarity calculation, and sentence ranking. The resulting summaries were rigorously evaluated by language experts and website specialists using a Likert scale to assess both the quality of the summaries and the usability of the system. The findings demonstrated that the system effectively generated summaries that retained essential information from the original articles, with the highest accuracy observed at a 50% compression rate (88.533%). Additionally, the system achieved good performance at 40% compression (85.133%) and 30% compression (81.26%). The web-based system allows users to input article text and quickly obtain a summary, offering a practical tool for researchers and readers to efficiently comprehend academic content.

Abstract

Tarutung merupakan salah satu wilayah di Sumatera Utara yang masih aktif dalam melestarikan tradisi tenunnya. Desain kain tenun Tarutung terus berkembang dengan motif yang lebih bervariasi, mencerminkan dinamika budaya yang menggabungkan tradisi dan tren kontemporer. Hasil wawancara yang dilakukan peneliti dengan 25 pemasok songket di Tarutung menunjukkan 72% (18 orang) mengalami kesulitan mengidentifikasi jenis tenun, terutama penjual baru dan sales promotor yang perlu menjelaskan detail produk kepada pelanggan. Hasil wawancara juga menunjukkan 80% (20 orang) penjual kesulitan mengetahui kegunaan tenun karena keberagaman yang ada. Pembeli sering bertanya tentang penggunaan yang tepat, seperti untuk pakaian, upacara adat, keagamaan, atau dekorasi, sehingga penjual perlu memberikan informasi yang akurat. Kesulitan membedakan jenis tenun disebabkan oleh kemiripan pola akibat perbedaan satu atau dua lidi dalam proses mamutik (pembuatan motif). Penjual biasanya berdiskusi dengan sesama penjual atau memeriksanya ke pengrajin, yang tentunya memakan waktu lama. Ketidakakuratan informasi dapat mengurangi kepercayaan pelanggan, menurunkan pendapatan, dan mempersulit penentuan harga. Penjual harus memastikan informasi produk akurat untuk menghindari kerugian. Penelitian ini bertujuan untuk membangun model klasifikasi tenun Tarutung berdasarkan motif menggunakan metode Convolutional Neural Network (CNN), yang diintegrasikan ke dalam sebuah website untuk mengidentifikasi jenis kain yang diunggah pengguna. Selain itu, website juga menyediakan informasi relavan yang memudahkan akses pengguna ke berbagai fitur yang tersedia. Penelitian ini menghasilkan model CNN dengan akurasi sebesar 94%, precision 96%, recall 94%, dan F1-score 94%.
