Semaphore is a communication method used to send and receive messages by utilizing flags, paddles, sticks, bare hands, or gloves. Semaphore signaling is commonly used in scouting activities (Pramuka). However, novice scouts often face difficulties in accurately recognizing semaphore gestures. Although guidebooks are available, errors may still occur, especially when learning independently. To address this issue, a gesture detection system using the Multi-Layer Perceptron (MLP) method and MediaPipe framework is proposed, which aims to evaluate the accuracy of MLP and MediaPipe in detecting semaphore poses. To assess the performance of the MLP model, a Confusion Matrix is used to analyze the number of correct and incorrect predictions and generate metrics such as accuracy, precision, recall, and F1-score. The evaluation results show that the system successfully recognized 122 poses correctly, achieving an accuracy of 93.84%, precision of 93.84%, recall of 100%, and an F1-score of 96.80%. Based on these results, the system is considered sufficiently accurate and can be used as an interactive learning tool to recognize semaphore codes, particularly in scouting activities.

Furniture has high added value and significant global competitiveness, largely due to the diversity of natural raw materials available in Indonesia, such as wood, rattan, and bamboo, as well as distinctive and high-quality designs. This advantage is supported by the skills and competence of the available human resources, making Indonesian furniture superior to products from other countries. Product quality is a key element in winning market competition, as it impacts customer satisfaction and loyalty. Masnur Joglo, a furniture company located on Jl. Muara Karya, specializes in producing various types of furniture from high-quality woods such as super mahogany and red teak. However, the purchasing system, which requires customers to visit the store directly and manually record prices, results in inefficiencies in terms of time and transportation costs. Customers often need to visit multiple stores to find the desired product, which is an inefficient process. To address these challenges, this study proposes the development of an Android-based sales application as a solution. This application is designed to expand Masnur Joglo's market reach and facilitate online ordering of furniture products, anytime and anywhere. The study aims to design and develop an Android-based sales information system that can enhance operational efficiency and streamline the sales process while better meeting customer needs. The application development method employs the waterfall model and uses MySQL and Firebase databases.
 

This research emphasizes the importance of health for every individual, as good health facilitates daily activities. One crucial aspect of health is physical health, which includes being free from various diseases. With the increasing public interest in traditional medicine, the information regarding the public's knowledge about traditional medicine also needs to be enhanced. Therefore, this research aims to develop a mobile-based traditional medicine information system at UPKM/CD Bethesda YAKKUM as an information medium for the wider community. The method used for system development in this research is the waterfall method, which involves stages such as concept, design, data collection, creation, and testing. The developed application is a mobile-based traditional medicine information system, designed to help introduce traditional medicine in Indonesia. This application is designed to be easily accessible without the need to worry about internet connection or data charges, and it can be used in various regions. The result of this research is a mobile-based information system application that provides information about traditional medicine for various diseases. This application includes information on types of medicinal plants, their benefits, and explanatory videos, making it easier for the public to learn about and understand traditiona l medicine.
