Abstract

The beauty industry in Indonesia continues to grow rapidly, with Wardah emerging as a leading local brand that garners numerous customer reviews on Instagram. Understanding these customer opinions is crucial, as they significantly influence brand perception and purchasing decisions. This study aims to compare the performance of K-Nearest Neighbors (KNN) and Naïve Bayes algorithms in classifying customer sentiment toward Wardah’s products on Instagram. The research follows the CRISP-DM methodology, involving data collection through web scraping, data preprocessing, and classification using both algorithms. The results show that KNN achieves higher accuracy (78.23%) than Naïve Bayes (74.56%), making it more effective in sentiment classification. KNN is advantageous in identifying distance-based patterns, while Naïve Bayes offers faster processing and easier implementation. These findings suggest that KNN is more suitable for accurate sentiment prediction. Wardah can implement a KNN-based sentiment monitoring system to track public feedback on product launches and campaigns, thereby enhancing marketing strategies and customer engagement

Abstract

Kegiatan Pengabdian Kepada Masyarakat (PKM) ini dilaksanakan untuk menjawab permasalahan rendahnya minat belajar anak-anak di Panti Asuhan LKSA Al-Izan’ni, yang dipengaruhi oleh keterbatasan metode pembelajaran, minimnya pemanfaatan teknologi interaktif, serta kurangnya keterampilan pengasuh dalam menggunakan aplikasi digital. Solusi yang ditawarkan berupa pelatihan penggunaan aplikasi pembelajaran interaktif, pendampingan, serta evaluasi implementasi dalam proses belajar. Metode pelaksanaan meliputi tahap persiapan, pelatihan pengasuh, implementasi aplikasi, hingga monitoring dan evaluasi. Hasil kegiatan menunjukkan peningkatan minat belajar anak-anak melalui penggunaan aplikasi seperti Duolingo dan Quizizz yang dikombinasikan dengan metode gamifikasi, kuis, dan video edukasi. Selain itu, keterampilan pengasuh dalam mendukung pembelajaran interaktif juga meningkat sehingga menciptakan lingkungan belajar yang lebih menarik, menyenangkan, dan efektif. Dengan demikian, program ini berhasil memberikan kontribusi nyata dalam mendukung kualitas pendidikan anak-anak di Panti Asuhan LKSA Al-Izan’ni.
