Abstract

Penelitian ini bertujuan untuk mengevaluasi sentimen pengguna terhadap aplikasi M-Pajak yang tersedia di Google Play Store menggunakan algoritma Naïve Bayes. Proses pengumpulan data dilakukan dengan teknik web scraping, menghasilkan 1000 ulasan pengguna. Dari 1.000 ulasan tersebut, 900 bersentimen negatif, 55 positif, dan 45 netral. Data ini dianalisis melalui tahapan Knowledge Discovery in Databases (KDD), mencakup preprocessing data seperti tokenize, transform case, filter stopword dan token by length. Algoritma Naïve Bayes diterapkan untuk mengklasifikasikan sentimen ke dalam kategori positif dan negatif. Pengujian evaluasi model dilakukan menggunakan cross validation, 10 k-fold stratified sampling dengan total 669 data, yang terdiri atas 630 data berlabel negatif dan 30 data berlabel positif. Model yang dihasilkan menunjukkan akurasi sebesar 89,84%. Hasil analisis mengungkap dominasi ulasan negatif, yang disebabkan oleh masalah teknis seperti error aplikasi, waktu respons yang lambat, dan antarmuka pengguna yang kurang intuitif. Penelitian ini merekomendasikan pengembang aplikasi untuk meningkatkan kinerja teknis dan desain antarmuka pengguna guna meningkatkan pengalaman dan kepuasan pengguna, sehingga mendukung penerimaan aplikasi yang lebih baik di masa depan.

Abstract

Penelitian ini menganalisis pola pembelian produk di Kedai "Ngenyod'S", dengan menggunakan algoritma FP-Growth untuk meningkatkan strategi pemasaranPola pembelian pelanggan sangat penting untuk membuat strategi promosi yang lebih baik dan mengelola stok.  Salah satu masalah yang dihadapi adalah tidak memanfaatkan data transaksi secara efektif saat menentukan strategi pemasaran.  Akibatnya, tujuan penelitian ini adalah menerapkan algoritma FP-Growth untuk menemukan itemsets sering dan pola asosiasi yang dapat digunakan dalam strategi bisnis berbasis data.  Proses penelitian ini terdiri dari beberapa langkah: pengumpulan data transaksi, preprocessing data, penerapan algoritma FP-Growth, dan analisis hasil dengan mempertimbangkan nilai dukungan dan kepercayaan tertentu. Dataset yang digunakan mencakup 508 penjualan dengan atribut seperti tanggal penjualan, nama produk, jumlah penjualan, harga satuan, dan pendapatan total.  Hasil penelitian menunjukkan bahwa beberapa produk, seperti Milo Milk dan Milo Ori, memiliki pola pembelian yang kuat dengan keyakinan sebesar 70%. Pola ini memberikan wawasan untuk strategi pemasaran, seperti menerapkan promosi bundling atau diskon untuk produk terkait.  Selain itu, penelitian ini menemukan bahwa algoritma FP-Growth lebih efisien dalam analisis data transaksi dibandingkan dengan metode konvensional. Kesimpulannya adalah bahwa penggunaan algoritma FP-Growth dapat membantu bisnis menemukan pola pembelian pelanggan, meningkatkan efisiensi pemasaran, dan mengoptimalkan manajemen stok. Studi ini membantu mengembangkan sistem rekomendasi berbasis pola pembelian yang dapat digunakan dalam bisnis ritel, terutama usaha kecil dan menengah.  Memperluas atribut dataset dan menggabungkan teknik lain seperti algoritma Apriori untuk mendapatkan hasil yang lebih lengkap adalah saran untuk penelitian lanjutan. Model serupa juga dapat diterapkan untuk meningkatkan efisiensi pemasaran berbasis data di berbagai industri bisnis lain.

Abstract

The development of digital technology has brought significant changes in the world of education, especially in online learning methods. Digital literacy is an essential skill for educators in navigating technology-based learning. This research aims to improve digital literacy for elementary school teachers in facing online learning challenges. The training program developed includes a basic understanding of digital technology, the use of learning software, and effective teaching strategies in an online environment. The research method used was a qualitative approach with observation, interviews and case studies in several primary schools in Cirebon district. The results showed that digital literacy training significantly improved teachers' competence in using technology and improved the effectiveness of online teaching. Teachers who participated in this training program were able to optimize the use of various digital platforms, improve interaction with students, and adapt the curriculum to better fit the online learning model. In addition, the main challenges faced include limited access to technology infrastructure and lack of adequate technical support. Therefore, more supportive policies in the provision of technology resources and continuous training programs for teachers are needed. The findings of this study confirm that improving digital literacy is a key factor in the successful implementation of online learning at primary school level. By improving teachers' competence in technology utilization, it is expected that the learning process can be more interactive, effective and adaptive to the times. This study also recommends the need to integrate digital-based curriculum so that teachers are better prepared to teach online materials.
