Abstract

Online transportation is a service that utilizes digital technology, such as mobile applications, to make it easier for users to book trips with just a touch on the phone screen. This convenience makes online transportation increasingly popular, especially in big cities in Indonesia. Two online transportation services that are widely used in Indonesia are Gojek and InDrive. These two platforms are inseparable from user opinions, which greatly affect the desires and competitiveness of each service. This study aims to conduct sentiment analysis on user reviews from the Google Play Store in order to compare the two applications using the Support Vector Machine (SVM) algorithm. This study shows that most of the 1000 Gojek and InDrive user reviews on the Play Store contain negative sentiment, especially related to driver delays and application disruptions. The Support Vector Machine (SVM) algorithm provides the highest accuracy of 86.11% at a training and test data ratio of 80:20, and shows relatively stable performance at other ratios. The dominant words in positive reviews are "good" and "fast", while in negative reviews are "old" and "cancel", indicating that the speed and brightness of the service are the main concerns of users. SVM is effective in analyzing online transportation review sentiment with high accuracy, and the analysis results reveal that users convey more complaints, especially regarding the speed and reliability of Gojek and InDrive services.

Abstract

The rapid development of information technology has become an essential element in various aspects of life, including the business sector. Robado Bakery, which has been operating since 2018 in Nusa Penida, faces challenges in managing orders, which are still manually processed through WhatsApp. This practice leads to unorganized record-keeping, overproduction, and the unavailability of required bread stock. To address these issues, this study aims to design and develop a web-based bread ordering information system. This research adopts the waterfall development method, encompassing stages such as requirements analysis, system design, implementation, testing, and maintenance. Data collection was conducted through observation, interviews, and literature studies. The results show that the waterfall method remains relevant for the design and development of structured and integrated web-based information systems, particularly in the context of order management. The implemented system successfully improves order tracking, displays real-time stock information, and supports pre-order functions, thereby optimizing store operations and reducing operational inefficiencies.

Abstract

Student learning interest plays a crucial role in educational success, as it directly influences engagement, comprehension, and academic achievement. This study aims to analyze the influence of pedagogical strategies on students’ learning interest using a machine learning approach with the Random Forest algorithm. Eight aspects of teaching strategies were examined as predictor variables, while learning interest was measured through two main indicators: interest in real-world application of the material and motivation for self-directed learning. Data were collected from 100 students via a Likert-scale questionnaire and analyzed using Orange Data Mining. The model was validated through 10-fold cross-validation and evaluated using accuracy, precision, recall, F1-score, and AUC. The results indicate strong model performance, with 95% accuracy, 96.7% precision, 97.8% recall, and a 97.2% F1-score. Feature importance analysis identified practical activities (P4), an inclusive learning environment (P6), and the use of technology (P3) as the most influential predictors of learning interest. In contrast, variables such as P1, P2, and P8 showed minimal contribution. These findings demonstrate that Random Forest is not only effective for classification tasks but also valuable in identifying key factors for improving pedagogical strategies. The results are expected to inform the development of more adaptive, interactive, and student-centered learning environments.

Abstract

This study aims to develop a prediction model to determine the method of delivery (normal or cesarean) using the Gradient Boosting algorithm based on maternal examination data. This model was evaluated using precision, recall, F1-score, and accuracy metrics. The results showed that the Gradient Boosting model had an accuracy of 48%, with better performance in predicting Normal delivery compared to Caesarean. Although this model is effective, there is an imbalance in precision and recall for the Caesarean class, indicating the need for improvement in identifying cases of cesarean delivery. Comparison with other algorithms such as Random Forest, Logistic Regression, and SVM showed that Random Forest gave the best performance with an accuracy of 55%. To improve performance, this study recommends hyperparameter optimization, application of class balancing techniques, and enrichment of medical features. The developed model has the potential to be used as a tool in medical decision-making related to delivery methods, which is expected to improve the safety of mothers and babies, and reduce dependence on subjective factors in medical decisions.

Abstract

This study conducts a comparative performance analysis of two widely utilized classification algorithms, Naive Bayes and K-Nearest Neighbors (KNN), in the context of customer satisfaction analysis based on product reviews from the Tokopedia e-commerce platform. Customer-generated reviews serve as a critical factor in shaping product reputation and perceived quality, while also influencing the purchasing behavior of prospective buyers.The methodology encompasses data collection of product reviews from Tokopedia, followed by a comprehensive preprocessing pipeline, including text cleaning, tokenization, and stemming. The processed reviews are then categorized into two sentiment classes-positive and negative-employing both Naive Bayes and KNN algorithms.The performance of these algorithms is evaluated using standard classification metrics: accuracy,recall,F1-score dan precision. Empirical results demonstrate that Naive Bayes yields superior accuracy in classifying product sentiments compared to KNN.This research offers practical insights for e-commerce businesses in selecting suitable machine learning techniques for sentiment analysis to better understand customer feedback and enhance satisfaction. Moreover, the study contributes to the academic discourse by highlighting the strengths and limitations of each algorithm, and provides recommendations for future research in developing effective sentiment classification frameworks for customer satisfaction measurement.

Abstract

Fire is a disaster that can cause significant material and human losses. Kampar Regency in Indonesia is a fire-prone area due to short circuits, human negligence, and environmental conditions. This study aims to predict fire risk based on historical fire incident data and environmental factors using the Naïve Bayes algorithm. This method was chosen because of its ability to classify large-dimensional data with high probability. The research stages include data collection, preprocessing, data exploration, modeling, and model evaluation. Data were tested using splits of 70:30, 80:20, and 90:10. The results showed that the Naïve Bayes algorithm was able to provide prediction accuracy levels of 95.82%, 96.00%, and 95.45%, respectively. The highest accuracy level was obtained in the 80:20 scenario. These findings indicate that Naïve Bayes is effective in predicting high-risk areas for fire and can serve as a reference for relevant parties in developing more targeted fire prevention and mitigation policies.

Abstract

Bus transportation in Indonesia plays a vital role in reducing traffic congestion and supporting sustainable urban mobility. This study aims to optimize the services of Trans Metro Deli Medan by analyzing operational patterns using the Partitioning Around Medoids (PAM) clustering method. The research applies a data mining approach to segment service performance based on passenger volume, travel time, departure frequency, and passenger satisfaction. The analysis results in three distinct clusters: Quiet (average 15 passengers, 38 minutes travel time, low frequency and satisfaction), Medium (50 passengers, 75 minutes, moderate frequency and satisfaction), and Dense (95 passengers, 105 minutes, high frequency and satisfaction). These clusters reveal strong correlations among operational variables and highlight disparities in service quality across routes. Based on the findings, service improvement strategies are proposed: enhancing service quality and visibility for quiet routes, maintaining operational stability for medium routes, and increasing fleet capacity with adjusted scheduling for dense routes. The study demonstrates that PAM clustering provides valuable insights for strategic planning and can significantly contribute to the efficiency and quality improvement of public bus services in Medan.
