Abstract

This study aims to evaluate and compare the performance of two recommendation system approaches, namely Collaborative Filtering (CF) and Content-Based Filtering (CBF), in providing relevant product recommendations to users in an e-commerce context. The dataset used consists of 120 data including 90 relevant and recommended products (True Positive), 20 recommended but irrelevant products (False Positive), and 10 relevant but not recommended products (False Negative). Based on the calculation results, both methods show a precision value of 0.818 and a recall of 0.900. This means that approximately 81.8% of products recommended by the system are truly relevant, while 90% of the total relevant products are successfully recommended to users. The F1-score value obtained of 0.857 illustrates a good balance between the accuracy and completeness of the recommendations generated by the system. Furthermore, to measure the level of rating prediction error, the Mean Squared Error (MSE) and Root Mean Squared Error (RMSE) metrics are used. The evaluation results show that the CF method has an MSE value of 0.0784 and an RMSE of 0.28, while the CBF method shows an MSE of 0.0961 and an RMSE of 0.31. The lower RMSE value of CF indicates that this method has better accuracy in predicting user preferences than CBF. Overall, both methods show good performance with a low error rate. However, CF proved slightly superior in providing recommendations that match user preferences, so it can be used as a basis for developing smarter and more personalized recommendation systems on e-commerce platforms.

Abstract

Searching for products online is often an inefficient and confusing process, especially when users do not know the exact name of the product or use terms that differ from the search system. Keyword-based searches tend to produce irrelevant results because the system only matches text literally without understanding the meaning. As users increasingly talk to digital devices, voice-based search technology has become a more natural and intuitive alternative. This research aims to develop a semantic-based voicebot supported by Natural Language Processing (NLP) to improve the effectiveness of product searches on e-commerce platforms. The designed system not only recognizes user speech but also understands the context, intent, and semantic meaning of the given commands. The research stages include collecting user voice data, training the Automatic Speech Recognition (ASR) model for voice-to-text conversion, and applying the semantic NLP model for interpreting the context of product searches. The testing was conducted using Indonesian voice commands in a simulated e-commerce scenario. The results showed that the system achieved an average Word Error Rate (WER) of 1.29%, indicating a high level of accuracy in recognizing speech and understanding user intent. The integration between ASR and semantic NLP proved capable of creating a more natural, responsive search experience that resembles the way humans think and communicate when interacting with online search systems.

Abstract

The rapid advancement of digital technology and the growing use of social media, particularly TikTok, create new phenomena in consumer behavior. One of the most notable phenomena is the rising trend of Pop Mart blind box products, driven by user-generated content (UGC) and fear of missing out (FOMO). However, not all exposure to these two factors automatically translates into purchase intention. Some consumers engage with such content merely for entertainment purposes, while the emotional impulse triggered by the scarcity of Pop Mart products may be temporary in nature. This study aims to analyze the partial and simultaneous effects of UGC and FOMO on purchase intention toward Pop Mart blind box products among Generation Z in Malang City.This study employed a quantitative approach with data collected through questionnaires distributed to 100 Generation Z consumers in Malang City, aged 16–30 years, who had been exposed to Pop Mart blind box content on TikTok. The respondents were selected using a purposive sampling technique. Data were analyzed using validity and reliability testing, classical assumption testing, multiple linear regression analysis, coefficient of determination analysis, and hypothesis testing with t- and F-tests, with assistance from SPSS. The findings revealed that user-generated content (UGC) had a positive and significant partial effect on purchase intention toward Pop Mart blind box products among Generation Z in Malang City, as indicated by a t-value of 5.841 and a significance value of 0.000 (< 0.05). Similarly, fear of missing out (FOMO) also had a positive and significant partial effect on purchase intention, with a t-value of 7.380 and a significance value of 0.000 (< 0.05). Furthermore, the simultaneous test showed that UGC and FOMO jointly had a positive and significant effect on purchase intention, as evidenced by an F-value of 62.918, which exceeded the F-table value of 3.09, with a significance value of 0.000 (< 0.05). The coefficient of determination (R²) indicated that UGC and FOMO explained 55.6% of the variance in purchase intention, while the remaining 44.4% was influenced by other factors not examined in this study. Based on the findings, it can be concluded that UGC and FOMO significantly influence purchase intention toward Pop Mart blind box products among Generation Z in Malang City. The combination of these factors has proven effective in shaping consumers' purchase intention. These findings highlight the importance of authentic social media content and psychological factors in influencing consumer behavior in the digital era.

Abstract

Digital service transformation and service quality improvements are the primary strategies of Perumda Tirta Kanjuruhan, Malang Regency, to enhance customer satisfaction. However, satisfaction growth has slowed down, creating a gap between efforts and results. This study aims to analyze the effect of digital service transformation and service quality on customer satisfaction, both partially and simultaneously. This research utilizes a quantitative method with an explanatory research approach involving 100 respondents. The sample was determined using a purposive sampling technique, targeting active customers for at least the last six months.

Empirically, the research proves that digital service transformation and service quality, both partially and simultaneously, have a positive and significant effect on customer satisfaction. Service quality is proven to have the most dominant influence compared to digital transformation. Therefore, Perumda Tirta Kanjuruhan is advised to continuously improve the standards of direct employee service quality and further optimize the functionality of digital service features to ensure sustainable customer satisfaction.
