Abstract

This study implements the Naïve Bayes algorithm for classifying spam and non-spam (ham) messages using the RapidMiner Studio platform. The dataset used was obtained from the SMS Spam Collection Dataset on the Kaggle platform, which consists of 5,759 messages with a distribution of 4,075 ham messages and 1,291 spam messages. The research stages included text pre-processing, model training, and performance evaluation using accuracy, precision, recall, and F1-score metrics. The experimental results showed that the Naïve Bayes model achieved an accuracy of 89.64% with a precision of 56.93%, a recall of 100%, and an F1-score of 72.56%. The research findings indicate that the Naïve Bayes algorithm is effective in detecting spam messages with adequate accuracy, and prove that RapidMiner is an efficient tool for implementing machine learning methods in text classification.

Abstract

This study aims to analyze and classify various food items based on their nutritional content using an unsupervised learning approach, specifically the K-Means Clustering algorithm. The increasing complexity of nutritional data requires effective data-driven methods to support accurate and efficient analysis. This research utilizes K-Means to group food items into distinct clusters according to their energy, fat, carbohydrate, protein, and fiber levels. The clustering process successfully identified three main groups that represent different nutritional characteristics. Cluster 1 consists of high-energy and high-fat foods suitable for individuals with high physical activity. Cluster 0 includes balanced-nutrition foods recommended for daily consumption, while Cluster 2 contains low-calorie and high-fiber foods ideal for weight control or diet programs. The results demonstrate that K-Means is effective in simplifying complex nutritional data and providing clear classifications for practical use. This study highlights the potential of machine learning as a valuable tool in nutritional analysis and digital health innovation. The application of this method can support the development of intelligent nutrition-based applications that help individuals manage healthy diets more effectively and contribute to promoting public awareness of balanced nutrition.

Abstract

Accounting management in sporting goods stores often faces challenges such as inefficient manual recording, error-proneness, and delays in presenting financial reports. This situation impacts suboptimal managerial decision-making. This study aims to apply the Scrum method to develop an accounting information system capable of improving the effectiveness of recording and presenting financial reports. The research method uses the Scrum framework approach, with the stages of product backlog, sprint planning, daily scrum, sprint review, and sprint retrospective. Each stage is implemented iteratively to adapt to user needs and minimize the risk of errors. The results show that the application of the Scrum method results in an accounting information system that is more structured, flexible, and tailored to the store's operational needs. This system simplifies the process of recording transactions, managing inventory, and preparing financial reports quickly and accurately. Thus, the system is able to support more informed decision-making for sporting goods store management
