Abstract

The rapid development of e-commerce has made promotional strategies increasingly vital, with free shipping vouchers standing out as one of the most effective tools to enhance consumer engagement. Shopee, as a leading player in the digital marketplace, has effectively utilized this strategy to boost user transactions by consistently offering free shipping vouchers. This study aims to analyze the influence of such vouchers on consumer purchasing decisions, focusing on users in Kelurahan Rengas Pulau. A quantitative research approach was adopted using a descriptive associative method. Data collection was carried out through the distribution of questionnaires to 200 respondents, selected using purposive sampling techniques. The data were then analyzed using regression analysis to determine the relationship between the use of free shipping vouchers and consumer purchasing behavior. The results of the regression analysis showed a strong and statistically significant relationship, with a regression coefficient of 0.620 and a p-value of 0.000. This suggests that the presence of free shipping vouchers substantially increases the likelihood of consumers making purchases. These findings confirm that free shipping promotions are a key factor in shaping consumer behavior, especially in suburban areas like Kelurahan Rengas Pulau. In conclusion, free shipping vouchers not only attract potential customers but also contribute to an increase in sales transactions. Businesses and e-commerce platforms should consider incorporating similar promotional tactics to maintain competitiveness and enhance customer satisfaction. This study affirms the positive and significant effect of Shopee’s free shipping incentives on user purchasing decisions, highlighting their strategic importance in today’s competitive digital marketplace

Abstract

Abstract: The rapid growth of the e-commerce industry in Indonesia compels companies to actively evaluate customer satisfaction through tingkat kepuasant analysis of app reviews. This study aims to compare the effectiveness of the K-Nearest Neighbors (K-NN) and Naive Bayes algorithms in assessing user satisfaction levels of the Shopee app as a component of IT governance. The research data comprises 2,000 samples of Shopee user reviews collected from Google Play Store and App Store, classified into five rating categories: excellent, good, fair, poor, and bad, based on textual content analysis. The preprocessing stage involved text cleaning (removing stopwords and punctuation), feature extraction using TF-IDF, and an 80:20 split of the dataset (training and testing). The analysis revealed significant differences between the two algorithms. K-NN achieved an accuracy of 54% with the optimal parameter *K=5*, while Naive Bayes demonstrated superior performance with 98% accuracy. The low accuracy of K-NN is suspected to stem from its sensitivity to data imbalance and noise in text features, whereas Naive Bayes, with its probabilistic foundation, better handles the sparse characteristics of review data. These findings emphasize the criticality of selecting appropriate algorithms in IT governance for user satisfaction analysis. Naive Bayes is recommended as the optimal approach for text classification in e-commerce reviews, while K-NN requires refinement through techniques such as feature normalization or class imbalance handling. The study also highlights the need to integrate adaptive models, such as deep learning, to enhance accuracy in complex scenarios. For future research, expanding data scope or implementing multilingual analysis could serve as strategic steps to improve result generalization. Keywords: K-NN, Naive Bayes, E-commerce, user satisfaction, IT governance, Shopee. Abstrak: Perkembangan yang cepat dalam industri e-commerce di Indonesia mendorong perusahaan untuk secara aktif mengevaluasi kepuasan pelanggan melalui analisis kepuasan pelanggan dari ulasan aplikasi. Studi ini bertujuan untuk membandingkan efektivitas algoritma K-Nearest Neighbors (K-NN) dan Naive Bayes dalam menilai tingkat kepuasan pengguna aplikasi Shopee sebagai komponen tata kelola teknologi informasi. Data penelitian mencakup 2000 sampel ulasan pengguna Shopee yang diambil dari Google Play Store dan App Store, dengan klasifikasi penilaian 5 kategori yaitu sangat puas, puas, cukup puas, kurang puas dan buruk pada konten teks. Proses pra-pemrosesan data melibatkan pembersihan teks (menghilangkan kata penghubung, tanda baca), ekstraksi ciri menggunakan TF-IDF, serta pembagian dataset menjadi 80% pelatihan dan 20% pengujian. Hasil analisis mengungkapkan perbedaan yang signifikan antara kedua algoritma. K-NN mencapai akurasi 58,50% dengan parameter *K=5*, sementara Naive Bayes menunjukkan performa lebih unggul dengan akurasi 100%. Rendahnya akurasi K-NN diduga berasal dari kepekaan algoritma terhadap ketidakseimbangan data dan gangguan pada fitur teks, sedangkan Naive Bayes, yang berbasis probabilitas, lebih mampu mengatasi karakteristik data yang jarang (sparse) dalam ulasan. Temuan ini menekankan pentingnya pemilihan algoritma yang sesuai dalam tata kelola TI untuk analisis kepuasan pengguna. Naive Bayes direkomendasikan sebagai pendekatan optimal untuk klasifikasi teks pada ulasan e-commerce, sedangkan K-NN perlu disempurnakan melalui teknik seperti normalisasi fitur atau penanganan ketidakseimbangan kelas. Studi ini juga mengidentifikasi perlunya integrasi model adaptif, seperti deep learning, untuk meningkatkan akurasi dalam skenario yang lebih kompleks. Untuk penelitian mendatang, perluasan cakupan data atau penerapan analisis multibahasa dapat menjadi langkah strategis guna meningkatkan generalisasi hasil. Kata kunci: K-NN, Naive Bayes, E-commerce, Kepuasan Pengguna, Tata Kelola TI, Shopee.
