Abstract

Information technology is growing rapidly, one of the examples is the library information system. The amount of interest in reading the public makes borrowing books that are increasingly crowded on the visit by young people and adults. Both who want to borrow a book, who want to just read in the library, and who will see what books are in the library. Libraries as providers of services to users or visitors require methods of service that are fast, easy and efficient. Existing library services are still manual causing various obstacles in the provision of services, for example library staff in providing services must record new book data into a master book, for members themselves when they want to borrow a book they have to record it into the borrow books data, calculation of the amount of fines that occur when the member is late in returning books to library staff, thus to improve services to library members it is necessary to build a system to facilitate librarians in serving their members. The research method used is Research and Development (R&D). The software development process model uses the waterfall model which consists of requirements analysis, design, implementation, and testing. Then the software used for developing this library system is Macromedia Dreamweaver CC2019, MySQL Database, Php My Admin and XAMPP.

Abstract

Serat optik merupakan media transmisi yang banyak digunakan untuk jaringan pada serat optik pada lokal. transmisi terdapat berbagai macam kerugian atau loss redaman, salah satunya dikarenakan penyambungan serat optik. Kerugian dari penyambungan serat optik disebabkan oleh metode penyambungannya, yaitu metode fusion dan metode mekanik. Pada tugas akhir ini dilakukan penelitian tentang pengaruh teknik penyambungan fusion dan penyambungan mekanik terhadap serat optik guna mengetahui metode mana yang lebih baik untuk digunakan. Adapun serat optik yang diamati menggunakan serat optik Single Mode dengan panjang 30m, 70m, 90 dan 160m. Hasil yang diperoleh berupa table kerugian dari penyambungan serat optik. Pada penyambungan fusion didapatkan hasil yang tetap yaitu 0,01 dB. Pada penyambungan mekanik didapatkan hasil yang tidak tetap yaitu 0,06 dB dan 0,13 dB. Dari hasil yang diperoleh maka dianalisis bahwa penyambungan menggunakan metode fusion menghasilkan redaman yang lebih kecil dibandingkan dengan penyambungan menggunakan metode mekanik

Abstract

Penelitian ini mengkaji efektivitas algoritma Naive Bayes (NB) dan K-Nearest Neighbors (KNN) dalam analisis sentimen ulasan pengguna aplikasi Vidio di Google Play Store. Evaluasi kinerja kedua model dilakukan menggunakan berbagai metrik, termasuk akurasi, precision, recall, dan Area Under Curve (AUC). Hasil penelitian menunjukkan bahwa KNN mengungguli Naive Bayes dalam beberapa aspek penting. KNN mencapai akurasi 74.92% dibandingkan dengan Naive Bayes sebesar 71.32%. Dalam hal precision, KNN juga menunjukkan performa yang lebih baik dengan nilai 76.52%, sementara Naive Bayes mencapai 71.61%. Meskipun demikian, kedua model menunjukkan kinerja yang sebanding dalam hal recall, dengan KNN mencapai 72.54% dan Naive Bayes 71.46%. Yang menarik, kedua model memiliki nilai AUC yang sangat tinggi dan hampir setara, yaitu 90.10% untuk KNN dan 90.00% untuk Naive Bayes, menunjukkan kemampuan yang sangat baik dalam membedakan sentimen positif dan negatif. Berdasarkan hasil evaluasi secara keseluruhan, algoritma KNN lebih direkomendasikan untuk implementasi analisis sentimen pada ulasan pengguna aplikasi Vidio.

Abstract

Ulasan pengguna aplikasi e-commerce di platform seperti Google Play Store merupakan sumber umpan balik vital bagi pengembang, namun volumenya yang masif menyulitkan analisis manual. Penelitian ini bertujuan untuk mengatasi tantangan tersebut dengan melakukan analisis sentimen otomatis pada ulasan aplikasi Tokopedia. Fokus utama adalah mengklasifikasikan sentimen ulasan ke dalam kategori positif dan negatif serta membandingkan secara empiris kinerja dua algoritma klasifikasi populer, yaitu Naive Bayes (NB) dan K-Nearest Neighbors (KNN). Metodologi penelitian mencakup tahapan pengumpulan data ulasan dari Google Play Store, pra-pemrosesan teks ekstensif (termasuk case folding, cleaning, tokenizing, stopword removal, stemming), ekstraksi fitur numerik dari teks, implementasi model NB dan KNN, serta evaluasi komparatif menggunakan metrik Akurasi, F1-Score, dan Area Under the Curve (AUC). Hasil evaluasi pada data uji menunjukkan bahwa algoritma KNN menunjukkan kinerja yang secara signifikan lebih unggul dibandingkan Naive Bayes. KNN berhasil mencapai akurasi sebesar 80.00% dengan nilai AUC 0.865, sementara Naive Bayes hanya mencapai akurasi 71.50% dengan nilai AUC 0.576 yang mengindikasikan kemampuan diskriminatif rendah. Penelitian ini menyimpulkan bahwa KNN merupakan metode yang lebih efektif dan reliabel dibandingkan NB untuk tugas klasifikasi sentimen pada dataset ulasan aplikasi Tokopedia ini, dan menawarkan potensi aplikasi praktis untuk memonitor opini pengguna secara otomatis.
