The growth of information technology has driven changes in consumer behavior, one of which is through e-commerce platforms such as Shopee. This phenomenon has generated a large number of customer reviews, including those for local cosmetic products such as Wardah. These reviews serve as an important source of information for understanding customer perceptions and satisfaction levels. However, manual analysis of large and linguistically diverse datasets is inefficient and potentially subjective. This study aims to implement the multi-category Naive Bayes algorithm to classify the sentiment of Wardah product reviews on Shopee into three categories: positive, negative, and neutral. The data were collected using a web scraping technique and processed through a series of preprocessing stages including case folding, tokenization, stopword removal, stemming, and text cleaning. Subsequently, term weighting was performed using the TF-IDF method prior to classification. Model performance was evaluated using a confusion matrix as well as accuracy, precision, and recall metrics. The results indicate that the multi-category Naive Bayes algorithm achieved an accuracy of 86.00%, a precision of 86.63%, and a recall of 98.24%. This approach can assist business practitioners in objectively understanding customer opinions and support decision-making in business strategy and product development.

To evaluate the classification performance, K-Fold cross-validation was employed with K values of 4, 5, 6, and 10 to ensure model reliability and robustness. Considering the issue of imbalanced datasets in user-generated reviews, the Synthetic Minority Over-sampling Technique (SMOTE) was utilized to balance the distribution of sentiment classes. Based on the confusion matrix, the Multinomial Naïve Bayes algorithm demonstrated effective performance in classifying sentiments, achieving satisfactory levels of accuracy, precision, and recall across different folds. These results indicate that the algorithm is capable of handling sentiment analysis tasks for local product reviews effectively. The findings of this study are expected to provide meaningful insights for businesses in understanding consumer perceptions, thereby supporting decision-making processes in product development, marketing strategies, and customer engagement for local brands.

This study explores the influence of digital marketing, service quality, and product innovation on customer satisfaction among Skintific skincare consumers on TikTok Shop. Employing a quantitative, explanatory research design, the study used purposive sampling to collect 200 valid responses from consumers who had purchased Skintific products via TikTok Shop. Data were collected through an online questionnaire and analyzed using multiple linear regression with SPSS, preceded by validity, reliability, and classical assumption tests. The results revealed that product innovation had the most significant impact on customer satisfaction (β = 0.589, p < 0.001), followed by service quality (β = 0.343, p < 0.001). However, digital marketing did not have a significant direct effect on customer satisfaction (β = 0.019, p = 0.746). The model explained 86.9% of the variance in customer satisfaction (R² = 0.869), indicating strong combined effects from the three factors. These findings suggest that post-purchase factors, particularly product innovation and service quality, are more decisive in influencing customer satisfaction than promotional efforts alone. Managerial implications highlight the importance of continuous product development, enhancing service responsiveness and reliability, and integrating digital marketing with value delivery to optimize customer satisfaction. The study contributes to social commerce literature by clarifying the distinct roles of marketing, service quality, and innovation in the context of TikTok Shop, providing both theoretical insights and practical guidance for brand strategy in social commerce platforms. This research adds to the understanding of how businesses can strategically leverage product innovation and service excellence to enhance consumer satisfaction and foster long-term customer loyalty in the competitive social commerce landscape.

This study aims to determine and analyze the influence of product development, service quality, and pricing on sales volume at PT Indoqurma Sejahtera, East Jakarta. The background of this study is based on increasingly fierce business competition, especially in the trading industry, so companies need to identify factors that influence sales volume. This study uses a quantitative approach with data collection techniques through distributing questionnaires to 50 employees directly involved in marketing and sales activities, using a saturated sampling technique. The research instrument was tested for validity and reliability before use. Data analysis was carried out using multiple linear regression using SPSS software version 19, which includes the classical assumption test, t-test, F-test, and coefficient of determination.
