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

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.

Abstract

The number of various kinds of e-commerce that can provide a variety of products and needs. Sellers and buyers do not need to meet face to face, because the products offered can all be done through e-commerce. Because there are too many types of e-commerce, a comparison is made to choose e-commerce that is in great demand by service users. Therefore, a study was made using the method Analytical Hierarchy Process (AHP)to compare several criteria from e-commerce that are in great demand. Analytical Hierarchy Process (AHP) is a research method for decision making by using a hierarchy and making comparisons on each criterion and alternative considered in decision making. The application of AHP in this study is to determine an e-commerce that is in great demand as one of the recommendations. The results of this study concluded that Tokopedia (40%), in the second position was Shopee (35%), in the third position Lazada (14%), and the latter is BukaLapak (11%).

Abstract

One of the efforts of higher education institutions to ensure the quality of graduates and the teaching and learning process is to improve the quality of teacher performance in the teaching and learning process. The quality of educational institutions is determined by a minimum of three factors, namely students, teachers and teaching and learning facilities, these three factors are interrelated and mutually support each other in creating a good learning process. This study aims to build a decision support system to facilitate the assessment of the best and productive teacher performance in learning by using the Analytical Hierarchy Process (AHP) method. For the object of my research, I used teachers and school principals by distributing questionnaires for questions about learning in the classroom and the scope of the school that served as a tool for educational institutions in assessing the best teachers. In order for the purpose of this decision support system to be successful, research and observation are carried out as objects in the preparation. Keywords : Best Teacher Performance Decision Support System With Using the Analytical Hierarchy Process (AHP) method.

Abstract

Learning the introduction of computer device for children is will very monotonous. Of course, this is not effective and efficient in the learning of children who tend to see something that attracts attention. In addition, very few elements that help learning include images and text. In teaching and learning activities, the learning method is the key to the success of the learning activities carried out. The method used in this research is by means of observation and literature study where researchers make direct observations and study, research and examine various literatures related to the subject related to the background of this educational game.
