Abstract

This research aims to explore the application of the Apriori algorithm in identifying purchasing patterns in the drop-off service industry in order to increase sales. Drop-off services often face challenges in designing effective marketing strategies due to limited understanding of customer purchasing behavior. In this study, the Apriori algorithm is applied to uncover recurring purchase patterns among customers, which are then used to develop more efficient marketing strategies. Customer transaction data is analyzed to find associations that reflect their purchasing preferences. The results show that the application of the Apriori algorithm successfully identifies patterns that can improve marketing strategies and, ultimately, increase sales. This research emphasizes the importance of applying data mining techniques to improve the performance of delivery services.

Abstract

This research explores the effect of applying Synthetic Minority Oversampling Technique (SMOTE) on the performance of Support Vector Machine (SVM) algorithm in sentiment classification on imbalanced datasets. Public review data was collected from social media platform X (formerly Twitter) regarding the Free Lunch Program, with a total of 2,368 reviews automatically labeled using the BERT model into three categories: positive, negative, and neutral. Sentiment imbalance in the dataset was addressed by applying SMOTE to generate synthetic data on minority classes. The research method follows the stages of Knowledge Discovery in Databases (KDD), including data selection, preprocessing, labeling, transformation using TF-IDF, SVM model training, and performance evaluation. The experimental results show that the application of SMOTE successfully improves the accuracy of the SVM model by 12.48%, from 71.41% to 83.89%. Other evaluation metrics, such as precision, recall, and F1-score, also showed significant improvement from 0.69, 0.71, and 0.68 to 0.84, respectively. These findings confirm that SMOTE is effective in overcoming data imbalance, resulting in a more accurate and reliable sentiment classification model. This research contributes to the application of sentiment analysis in data-driven public policy evaluation.

Abstract

History education in secondary schools still faces challenges in presenting material that attracts the digital generation’s attention. The Bandung Lautan Api event, a topic rich in local and national values, is often taught using conventional methods that limit student engagement and motivation. This study evaluates the feasibility of Augmented Reality (AR)-based learning media to enhance students’ historical literacy on the Bandung Lautan Api topic. A quantitative approach was applied using three integrated evaluation models: the System Usability Scale (SUS), User Experience Questionnaire (UEQ), and Technology Acceptance Model (TAM), involving 100 respondents comprising high school teachers and students. The results indicate that the AR media demonstrates excellent usability (SUS = 87.69), a highly positive user experience across all UEQ dimensions (highest attractiveness = 2.12), and strong technology acceptance (PU = 5.87; PEOU = 5.69; BI = 6.18). Both teachers and students shared consistent perceptions. These findings confirm that the AR media is feasible and capable of creating immersive and interactive learning experiences. Theoretically, this research enriches AR-based learning evaluation literature, while practically, it provides a ready-to-adopt model for integrating AR into history education.
